[MRE] Xen stable update to 4.2.2

Hi There

Would like to see this as upgrading to 13.04/xen 4.2.1 broke pci-e passthrough for me but is fixed in 4.2.2.

Status changed to 'Confirmed' because the bug affects multiple users.

+1. I'm trying to do some PCI passthrough as well.

Actually for Saucy I would rather like to get Xen 4.3 uploaded instead.

The provisional micro-release exception for Xen includes the following caveat:

Xen, first SRU needs to define a formal regression test procedure, such as "boot the last N releases/LTS default install and verify some list of things (networking, file system test suite, etc.)" (2013-07-22)

Where has that been defined? I do not see it in the description here.

Hello Stefan, or anyone else affected,

Accepted xen into raring-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/xen/4.2.2-0ubuntu0.13.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Hi Brian,

not formally yet as I wanted to write that down here as comments with results. Need to see how much effort it will be to leverage some or more of the regression testing that xen upstram does on the git repos. But since I am travelling right now it will get delayed till next week.

Adding the test results as an attachment to keep the formatting sane. Note on the one occasional failure of the security QRT run: one of the tests for /proc/<pid>/maps turns out to be racy at least (I need to talk to the security team about it). But failing or not failing is only depending on execution speed of the test and not a regression at all.

So from my point of view I would hope this to be sufficient regression testing.

This bug was fixed in the package xen - 4.2.2-0ubuntu0.13.04.1
