No problem, freeze is there to find bugs, you found a serious bug, let's fix it before the release. [...] > //sleep(20); > sleep(1); does sleep(20); there avoid the problem ? There is a failure in guest start but we don't get a proper description There is no urging deadline, except well for the pending patches waiting for the end of the freeze, if we can fix this by Monday, then that would be IMHO just fine. If on Monday we still don't have a solution let's discuss the status of the analysis, okay ?

[Libvirt-announce] Entering freeze for libvirt-1.0.3
by Daniel Veillard 27 Feb '13

27 Feb '13

I have just tagged git and pushed the tarball. The rpms for F17 are following too at the usual place: ftp://libvirt.org/libvirt/ I gave a try to the set of rpms and this seems to work fine for relatively simple tests, but of course more testing and checking on other architectures is needed ! If everything goes fine, I will make an rc2 in a couple of days and then we can decide if a final release on Friday is fine or if we need to postpone to next week, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

Hum, i just read your patch but i don't have enough knowledge of qemu parameters to know if there is large side effect to your patch. Also you remove code which is about core and replace it with something completely different. As is and with the amount of details you provided I can't make any jugement of how bad or good those changes are. One thing is sure, bug fixes can go in, they are fine during freeze !
