[libvirt] [PATCH] qemuDomainAttachDeviceLive: Check provided disk address
by Michal Privoznik 30 Sep '15

30 Sep '15

https://bugzilla.redhat.com/show_bug.cgi?id=1257844 Imagine an user who is trying to attach a disk to a domain with the following XML: <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/sr0'/> <target dev='vde' bus='virtio'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> The XML is obviously wrong.

[libvirt] Entreing freeze for libvirt-1.2.20
by Daniel Veillard 30 Sep '15

30 Sep '15

I'm afraid I forgot to warn about this last week, but we are close to the end of the month and it's time ! I have tagged the git tree and pushed release candidate 1 signed tarball and rpms at the usual place: ftp://libvirt.org/libvirt/ I didn't really had time to give it a bit of testing, at least it compiles and build fine <grin/>, so it may be broken, check it ! Plan is to have an rc2 probably on Wednesday, and final release on Friday. Hope that works for everyone !

Had a chance to run with your log settings. The query-migrate doesn't seem to have a corresponding "return" in the logs. So as you say, there may be a qemu bug that is not returning a response when the fd is still open(as libvirt didnt close it) but no read actually happening there. I felt qemu can't sense the failure as the fd is open, so posted this patch. Though, the qemu should return with the current state of migration as it sees instead of not returning at all. Hope we are on the same page. Mailer refused my reply as the attached logs with the mail crossed 300KB. Not attaching the logs for now. Please let me know if you want to me check anything specific.
