Don't allow reads of /proc and modprobe zfs through
New zfs_supported check reads /proc/filesystems to see if
zfs is already available and attempts to modprobe. These things
fail under launchpad sbuilds. Make sure to mock out the calls to
these functions and provide positive values for the failing unittest.
vmtest: enable persistent journal and collect at boot time
Target OSes which use systemd-journald may or maynot enable a
persistent journal on the root filesystem. If the target release
supports journald, issue the commands to create a persistent
journal. During the boot phase, issue commands to flush the
journal and collect (and compress) the journal as the last
script before tar'ing the collect data.
Rename vmtest_pollinate.yaml to vmtest_defaults.yaml. This
file is included in all vmtest runs.
This adds some decorators and functions to easily time function call.
It was originally done to get an idea on how much time we spend waiting
for udevadm settle, but the code is generally useful.
Note that the 'cmd_install' timer unfortunately doesn't make it
into the saved-off log as the message is appended after it is copied.
parse_dpkg_version: support non-numeric in version string.
This fixes parse_dpkg_version for packages with non-numeric (0-9.)
in their versions. It also improves it to work for native packages.
Native packages do not have '-'. Also adds tests of parse_dpkg_version.
block: use uuid4 (random) when autogenerating UUIDS for filesystems
The use of uuid1 (timebased) results in UUID values that are visually
hard to distingish. Instead use uuid4 which generates a random
UUID value to provide a more visually distinctive /etc/fstab.
Updated tools/xkvm to add a virtio-rng device when launching VMs
I believe that this change removes the final 2G root (/) filesystems.
These 2G filesystems were too small to handle upgrades sometimes.
Things that lead to this state:
a.) we started testing with propsed enabled (and upgrade to it)
b.) the failing cases here were Trusty HWE tests, which end up
getting 2 kernels installed and 2 update-initramfs and such.
That worst case scenario led to the following output of apt:
Need to get 2404 kB of archives.
After this operation, 10.9 MB of additional disk space will be used.
Need to get 1467 kB of archives.
After this operation, 4904 kB of additional disk space will be used.
Need to get 68.3 MB of archives.
After this operation, 308 MB of additional disk space will be used.
Need to get 63.9 MB of archives.
After this operation, 275 MB of additional disk space will be used.
