Nominating as a Beta blocker per https://fedoraproject.org/wiki/Fedora_19_Beta_Release_Criteria#Self_hosting_virtualization : "The release must be able host virtual guest instances of the same release." The criterion basically requires F19-on-F19 virt to work, and if I can't attach an F19 ISO to a VM, I can't really do that. I am seeing this as well. +1 blocker *** Bug 958697 has been marked as a duplicate of this bug. *** +1 blocker. I've met this one too. Note - the crash comes through abrt's ccpp handler, not pyhook, and there is no 'normal' Python backtrace in the report directory, just the core_backtrace . It's like the python interpreter itself crashed, I guess? Anyhow, it doesn't seem like a 'normal' Python crash. Both "Local install media (ISO image or CDROM)" (attach an iso) and "Import existing disk image" crashes virt-manager.

Discussed at 2013-05-06 blocker review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2013-05-06/f19beta-blocker-review-3.2013-05-06-16.02.log.txt . We agreed this doesn't quite need to be a blocker: it's annoying for those of us doing f19-on-f19 testing, but there are alternatives to virt-manager for that, we mostly have f18 systems available, and this issue can be fixed with an update (the fix doesn't need to be on the frozen media). Obviously, we'd like it to be fixed ASAP, though. commit 7e23244096da09a5ae2e5f9559a7a12804c1b57a Author: Cole Robinson <crobinso> Date: Wed Apr 17 17:39:25 2013 -0400 Port from gconf to gsettings looks like the recent change that touched this stuff. I think the relevant gsettings key was just inadvertently left out of the new schema. As the commit message notes: "Another big piece is that gsettings can't accept arbitrary paths like gconf would, everything needs to be described in the schema." So I think the key didn't need to be explicitly listed in the schema for gconf, but it does for gsettings, and it was just missed. I'm experimenting with a patch that adds the relevant key into the schema (maybe I'll have more luck than Reartes). It looks like it should be a boolean, no idea if it should default to true or false (the name of the key makes it rather difficult to guess what 'true' and 'false' actually mean), but I don't think it's too important, so I just guessed. OK, got a scratch build that works: http://koji.fedoraproject.org/koji/taskinfo?taskID=5337928 I just added the appropriate key to the gsettings schema: <schema id="org.virt-manager.virt-manager.paths" path="/org/virt-manager/virt-manager/paths/"> ... <key name="perms-fix-ignore" type="b"> <default>false</default> <summary>Ask about fixing permissions</summary> <description>Whether to ask about fixing path permissions</description> </key> </schema> and adjusted virtManager/config.py to look for paths/perms-fix-ignore rather than paths/perms_fix_ignore . Pretty trivial. I won't post the patch unless Cole wants as I'm sure he can re-create it in ten seconds and he probably wants the schema key to be slightly different. But this gets it flying for now, for me. This fixes the bug for me too. Thanks!
