The criteria only require virtualization to work at Beta, and then only N on N and N on N-1, not N on N-2. For me, both 19 on 19 and 19 on 18 work at present. So I'm -1 to this.
Comment 5 Reartes Guillermo 2013-03-23 15:29:53 UTC 
I looked at this issue again, and found that it did not affect all guests just one (i did not test all guest yet), and for the affected one, adding 'selinux=0' boot parameter fixed the issue.

I don't known why selinux selected that guest in particular for failing, it has a lot of AVCs. The other guests booted fine with the defaults boot parameters.

I'm also -1 to this now, since it is not even a general issue.

Discussed at 2013-03-27 blocker review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2013-03-27/f19alpha-blocker-review-3.2013-03-27-16.01.log.txt . Rejected as a blocker per criteria and comment #5.

Re-assigning to correct component; are you still seeing this one? Any more useful info on the affected VM?
Comment 8 Reartes Guillermo 2013-05-15 02:48:25 UTC 
> are you still seeing this one? Any more useful info on the affected VM?

no, and that is a good thing.
maybe this can be closed, i will re-open if i encounter it again.
Comment 9 Adam Williamson 2013-05-15 02:50:41 UTC 
OK, let's go with that. Thanks!
