Commit message

added multi-nic support

Description of the change

Add support for instances having multiple nics. Also affected many changes regarding interaction between projects and networks, host management, network and host interaction, network creation, compute gets all network information through the network api and passes it to virt, virt should no longer make network related db calls, ..., i'm sure there is more.

$NOVA_DIR/bin/nova-manage --flagfile=nova.conf network create public 10.1.0.0/16 1 8 0 0 0 0 xenbr1
$NOVA_DIR/bin/nova-manage --flagfile=nova.conf network create private 10.2.0.0/16 1 8 0 0 0 0 xenbr2

will create two networks, one labelled public the other private with different ip ranges, each network will result in a vif being created on instances attached to xenbr1 and xenbr2 respectively. Supposing you are using flatdhcp or vlan, you can/must also pass in a bridge interface (ex: eth1) so that the network bridge will be connected to the correct physical device when created.

I'd also like to point out that I'm not well equipped for testing the flatDHCP and vlan network managers, so I'm asking for help in this regard.

Unittests pass, but I have skipped a few them because their respective areas of code are probably broken: ex vmware.

The new host management structure is a little bit tricky. Hosts are not specified by users in any way. If a new network is added, a host will pick it up and configure itself as part of its periodic task. BUT the networks can be created before hosts are booted, and the network host can be set, and the network hosts will configure themselves for their networks on boot. I found this was best for allowing easy scaling and pre-configuring. Related to this, if a network does not yet have a host it is considered unconfigured and therefore, will not be included in the pool of networks chosen for an instance. This also applies to networks being chosen to associate with a project. This will result in a NoMoreAddresses error if you attempt to create an instance before any of the networks have been picked up the network hosts.

feel free to tear it apart,

Good work Trey.

I deployed your multi-nic branch into our environment and found one issue while spinning a new instance.

No, I think that nova/network/manager.py:get_instance_nw_info() doesn't return enough
information of network. It would be like this.
(it may be exist more elegant way to copy network to network_dict :-)

If libvirt had worked successfully I would have been surprised. The only hypervisor I supported in this patch was xen.

If it comes to moving some of the information in the network_info tuple from the info portion to the network portion, I can do that, but I won't have it existing in both. The original idea was for network to be the network db object and for info to be the info an instance might need to configure networking. And then passing around network objects failed when going through rpc. What I would prefer is if the relevant areas of libvirt would refer to the info portion of the tuple. That is unless there is disagreement in the way I've set up the network_info tuple, which would require more drastic change.

As for network delete, Dan can you make a paste of your virtual interfaces and networks tables for me?

Impressive work, Trey. I don't see any major problems, just some style/cleanup stuff. I would really like to see massive merge props like this split up (Launchpad truncates at 5000 lines), but I can understand if there may not have been a logical break point.

I noticed several of the docstrings you added could use some reformatting. Would you mind adding capitalization/punctuation where necessary and following sphinx syntax for parameters? This doesn't apply to bin/nova-manage (I think).

619: This new method name implies returning a single fixed_ip, but it still returns a list. Would you mind changing it back? Same goes for the 'fixed_ip_get_by_virtual_interface.' I feel like that name should be pluralized since it also returns a list.

4279-4284: This change is also unnecessary.

2106: Can you make this inherit from NovaException and change the name to something more descriptive? Maybe "VirtualInterfaceCreationFailed" or something. I know it's long, but it describes the error better than just "VirtualInterface."

2129: Could you make NoFixedIpsDefinedForHost inherit from NoFixedIpsDefined? If there are any other exceptions like this that you added I would appreciate it if you would define the correct inheritance. It can be really handy.

It also seems that NoFloatingIpsDefined, NoFloatingIpsDefinedForHost, and NoFloatingIpsDefinedForInstance aren't used anymore. Should we delete those?

3947: Aren't we supposed to put "Copyright 2011 OpenStack LLC." on all of the copyright notices, with any other contributing companies listed under it? I may just not know the correct policy here.

As for all of the skipped tests: I would prefer to see them fixed, but if it is going to be a lot of work, I am okay leaving them for now. I think we may want to file a bug or something so we don't forget about it.

I think we may want to follow up with another merge prop to make the OSAPI display this new information correctly. Right now we have hard-coded public/private networks. We should really be using the new network labels. Again, this isn't something I expect in this MP, just something I don't want us to forget about.

Trey,

It looks like maybe you removed vm_mode from Instance in models.py, perhaps unintentionally--however, its not showing up in the diff on Launchpad. Can you check on that in your checkout?

I'm not sure what vm_mode is used for but it doesn't seem to be removed during the migration so I'm assuming something needs fixing here.

Just looked again and realized the issue with vm_mode is you need to merge trunk and bump your migrate version numbers. And should those *.sql files be in there?

I went back and forth about this a few times.. If, for example, an instance may have multiple widgets, then it seems widget_get_by_instance() should return that list. Otherwise we'd have widget_get_all_by_instance() and widget_get_first_by_instance() and widget_get_last_by_instance() and..... In addition, there are other similar functions, should they all be changed, and to what? widgets_get_by_instance(), widget_get_all_by_instance(), widgets_get_all_by_instance() ? There doesn't seem to be a standard. Maybe we should set one.

Is it the name of the exception that is important or the message? For example, I don't see why we'd want to have 50 different VirtualInterface exception classes when we can have one that can handle any and all VirtualInterface exception messages. If there is a reason, please excuse my ignorance.

I can do this yes. But I'd still like a response to the question posed in the previous paragraph. Seems cleaner to have a FixedIP class exception and it handled all of the possible messages.

Some of the floating ip exceptions are not being used and they should be.

I corrected an error where someone had been using floating ip exception classes with the fixed ips by copy and pasting what they had done for floating ips in the exceptions and didn't really put much thought into the exceptions themselves. I guess they never raised similar exceptions for the floating ips. I can correct this.

I see what you mean. We also have the methods 'instance_get_fixed_addresses' which is another option.

It may just be my preference, but I like to use exception names to communicate the actual error, while the message can have more of a description and any extra information (through keyword arguments). I also like the inheritance hierarchy because you can try/except a more basic 'VirtualInterfaceError' and catch any of its more specific subclasses. Again, it may just be my personal preference. Maybe somebody else can chime in here.

I think the virtual interfaces records should be deleted at the time of releasing the fixed IP address and not in the deallocate_for_instance method.

Any functions which require network_info need to have it passed in from compute or somewhere else in libvirt which received it from compute. I started down that rabbit hole and quickly reverted when I found there were functions that called libvirt/netutils.py get_network_info() that didn't have network_info as a function argument at all.

Comments:

Tushar, most changes implemented. I'm curious why you'd like to have release_fixed_ip delete the virtual interface row instead of deallocate for instance. To me this seems like a bad plan. Supposing an instance has a virtual interface with multiple fixed_ips associated with it. I would like to be able to release one of the fixed_ips (but not all) without deleting the whole virtual interface... In addition, when migrating instances, we may want to release the IPs, but keep the mac addresses, meaning the virtual interfaces should remain in tact in the db.

Sandy, you're next.

You have a valid point here. Instead of deleting the virtual interfaces from the release_fixed_ip method you can delete them in the deallocate_for_instance as you did it before. But in this case virtual interfaces shouldn't be referred in the release_fixed_ip method otherwise it gives exception since this release_fixed_ip method is invoked by the nova-dhcpbridge script by the dnsmasq process way after deallocated_for_instance is called.

I see following exception :-

yes it is. I've got pressure to get this merged. I/we aren't responsible for all the different hypervisors/APIs hence having lieutenants. Multi-nic actually breaks some functionality in them, so of course it will also break some of their associated tests. It could be done where we go in to each hypervisor/API and make sure they are prepared to work with or without multi-nic prior to merging multi-nic and then remove any shims after, but that could take ages and is hard to manage. Instead we're basically taking a "push this with bugs and skipped tests approach". This allows the rest of hte network planning/development to start immediately and the rest of the fixes can be done in parallel by the parties responsible or requiring use of the hypervisors/APIs which are broken. I'm not going to say it's ideal, but it works and at the same time forces a clear division of labor.

skipped! Near as I can tell without getting all the way in the rabbit hole, there is some underlying rpc stuff not being stubbed correctly so it just waits and waits for a response. This should not cause API tests to fail. You mentioned earlier they weren't unittests. I think this is a problem. We should be able to develop in one area without breaking a bunch of (seemingly) unrelated tests. I think there are also 10 different network_info fake data structures floating around the tests. This kind of thing is bad juju.

> Questions:

Good one! Let's see, in pseudololcode:
loldef remove_network(network):
  if network haz project
     we raises
  elses
     we deletes

This wasn't written to handle flat networks which don't ever have associated projects. So you'd have instances with virtual_interfaces that have associated fixed_ips. When you delete the network, the row in the networks table would go away (be set to DELETED), but the fixed_ips would still exist and be associated with everything. How do you see this working, best case scenario? I can see doing something like checking to see if the network has any allocated_fixed_ips and fail if so. What about the fixed IPs, should those go away? For DHCP and vlan managers we'd also have to reconfigure the network host associated with that network (it doesn't really make any different for the hosts in flatmanager). I don't think the network delete functionality is fully functional yet. Maybe outside the scope of multinic?

Need a bit more context, by this do you mean:

I tested again the above problem with your latest branch and this time I am not able to reproduce it. The fixed ip address virtual_interface_id is set to NULL when virtual interfaces are deleted in the deallocate_for_instance method.

Now I see only 2 exceptions, one in the release_fixed_ip method and another in the lease_fixed_ip method. In both the cases the virtual interface is referred which is already deleted in the deallocated_for_instance method.

Perhaps a specific function for each test, with no conditionals in it?

Yeah, that's my ignorance of the domain showing through. Perhaps it's really something for Anne to head up. So many switches around network it's hard to know what's what.

You have completely eliminated checking of mac address from both these methods so now there is no question of getting these exceptions. But IMO, mac address checking is very important without which it is possible to release fixed ip which is associated with another instance.
But having said that, I don't see there is any problem here because until this fixed ip address is not disassociated it cannot be assigned to another instance.

To keep mac address checking intact, you can have to set delete status to True in the virtual_interfaces db table instead of deleting the virtual interfaces records of that instance.

Apart from that, during testing rev 854 I am getting following errors:-

1) While upgrading database using nova-manage db sync command , I get following error:-

OperationalError: (OperationalError) (1005, "Can't create table 'nova.#sql-51a_f3a' (errno: 121)") 'ALTER TABLE fixed_ips ADD CONSTRAINT fixed_ips_virtual_interfaces_fkey FOREIGN KEY(virtual_interface_id) REFERENCES virtual_interfaces (id)' ()

I am using Mysql 5.1.49.

I think this problem is not relevant to you since "provider_fw_rules" db table is not added in the trunk.

Sorry this "provider_fw_rules" db table is already there in the 027_add_provider_firewall_rules script. May be this db table is not added because of the issue #1.

This is my mistake again, I tried to sync the database from rev 849 to rev 850 of yours branch.
If I try to sync db on the clean database, I don't get this problem. Closing issue #1 also.

The IP can't be released if it is allocated. I don't see how this is a problem. Are you suggesting I move up in the function where it checks for the ip being allocated?

The problem with this is that we'd have unused mac addresses in the table and the column is unique'd for creating new mac_addresses. I delete them so they can be reused without issue.

I can't replicate or find anyone else able to replicate this error. Looking into this I did fix a syntax error, but I don't think it was related to your issue.

You are correct. I take back my problem but now mac parameter is redundant and should be removed from both release_fixed_ip and lease_fixed_ip methods.

Hey Vish,

Sorry. I've been working w/ Trey a bit offline to address these issues. Perhaps I need to use a different networkmanager. I'm using FlatDHCP with XenServer and Libvirt. I haven't actually been able to boot an instance with that sort of setup.

Couple of things I've noticed recently:

root@nova1:~# nova-manage network create private 192.168.0.0/24 1 254
root@nova1:~# nova-manage network list
network netmask start address DNS
192.168.0.0/25 255.255.255.128 192.168.0.2 8.8.4.4

I would have expected my network created with multi_nic to be named '192.168.0.0/24' instead of '192.168.0.0/25'.

---

Additionally I'm hitting this error with regard to floating IPs when trying to boot an instance:

So we have a small issue where the IP's don't show up in the OSAPI v1.0.

try:
nova-manage network create private 192.168.0.0/24 0 256

Jason Koelker has a branch that is modifying the way networks and ip addresses interact, including creation so the fact that this syntax doesn't make a whole lot of sense will be going away.

Very easy fix, but I've had exactly zero luck with any API related changes lately due to API zealots and their contracts. Here's the diff that would fix it. I have no problem adding it if you guys agree.

197+MultiNic
198+========
199+
200+What is it
201+----------
202+
203+Multinic allows an instance to have more than one vif connected to it. Each vif is representative of a separate network with its own IP block.
204+
205+Managers
206+--------
207+
208+Each of the network managers are designed to run independently of the compute manager. They expose a common API for the compute manager to call to determine and configure the network(s) for an instance. Direct calls to either the network api or especially the DB should be avoided by the virt layers.
209+
210+On startup a manager looks in the networks table for networks it is assigned and configures itself to support that network. Using the periodic task, they will claim new networks that have no host set. Only one network per network-host will be claimed at a time. This allows for psuedo-loadbalancing if there are multiple network-hosts running.
211+
212+Flat Manager
213+------------
214+
215+ .. image:: /images/multinic_flat.png
216+
217+The Flat manager is most similar to a traditional switched network environment. It assumes that the IP routing, DNS, DHCP (possibly) and bridge creation is handled by something else. That is it makes no attempt to configure any of this. It does keep track of a range of IPs for the instances that are connected to the network to be allocated.
218+
219+Each instance will get a fixed IP from each network's pool. The guest operating system may be configured to gather this information through an agent or by the hypervisor injecting the files, or it may ignore it completely and come up with only a layer 2 connection.
220+
221+Flat manager requires at least one nova-network process running that will listen to the API queue and respond to queries. It does not need to sit on any of the networks but it does keep track of the IPs it hands out to instances.
222+
223+FlatDHCP Manager
224+----------------
225+
226+ .. image:: /images/multinic_dhcp.png
227+
228+FlatDHCP manager builds on the the Flat manager adding dnsmask (DNS and DHCP) and radvd (Router Advertisement) servers on the bridge for that network. The services run on the host that is assigned to that nework. The FlatDHCP manager will create its bridge as specified when the network was created on the network-host when the network host starts up or when a new network gets allocated to that host. Compute nodes will also create the bridges as necessary and connect instance VIFs to them.
229+
230+VLAN Manager
231+------------
232+
233+ .. image:: /images/multinic_vlan.png
234+
235+The VLAN manager sets up forwarding to/from a cloudpipe instance in addition to providing dnsmask (DNS and DHCP) and radvd (Router Advertisement) services for each network. The manager will create its bridge as specified when the network was created on the network-host when the network host starts up or when a new network gets allocated to that host. Compute nodes will also create the bridges as necessary and conenct instance VIFs to them.
