To accomplish that we've worked on a small patchset to cover only the guest side - avoiding changes beyond that. All patches are upstream.

Hi Ziviani,

Could you please add an SRU request template to the bug report, as described
in [1]? We are interested mainly on the regression potential of these changes
and how they can be tested.

Another thing to notice is that the format of the URL for the BugLink would be:

https://bugs.launchpad.net/bugs/<bug number>

But we can fix that when applying.


Thanks!
