[libvirt] [PATCH] spec: Yet another permission fix for qemu dirs
by Martin Kletzander
Since we autogenerate path for QEMU guest agent into
LOCALSTATEDIR /lib/libvirt/qemu/channel/target/, the process should be
able to access that socket no matter under what user/group it is
running co you can set the user/group in qemu.conf.

[libvirt] Reopening file descriptors
by Christopher Pereira
Hi,
I'm chasing a bug related with libvirt not being able to resume a VM
paused because of an IO Error for images stored on a gluster volume.
The bug was reported in oVirt here:
https://bugzilla.redhat.com/show_bug.cgi?id=1058300#c39
To reproduce:
1) Run a VM on a gluster volume
2) Stop the gluser volume (VM will be paused)
3) Start the gluster volume
4) virsh resume VM (will fail)
QEMU logs will say:
block I/O error in device 'drive-virtio-disk0': Transport endpoint is
not connected (107)
And VM will not be resumed.
My guess is that libvirt is not telling QEMU to reopen its file descriptors.
Can someone please confirm or fix?

[libvirt] [PATCH 0/9] Make capacity optional when creating volumes
by Ján Tomko
If the volume has a <backingStore> or we are cloning a volume,
we don't need to know the capacity upfront.
https://bugzilla.redhat.com/show_bug.cgi?id=958510
Ján Tomko (9):
Add flags argument to virStorageVolDefParse*
Parse backingStore before capacity in volume XML
Allow parsing volumes without specifying the capacity
Allow cloning volumes with no capacity specified
Fix error messages in virStorageFileGetMetadataFromFD
Probe for capacity in virStorageBackendUpdateVolTargetInfo
Revert "Restore skipping of setting capacity"
Allow omitting volume capacity when backing store is specified
Allow creating volumes with a backing store but no capacity

[libvirt] [PATCH for 1.2.13] schema: Add virtio-mmio address type into RNG
by Martin Kletzander
The "virtio-mmio" is perfectly valid address type which we parse and
format correctly, but it's missing in our RNG schemas, hence editing a
domain with device having such address fails the validation.

[libvirt] QEMU's File Descriptors
by Christopher Pereira
Dear Martin,
Does libvirt currently reopen image files when resuming a VM?
There is an issue of an IO Error after restarting a gluster volume and probably doing other maintenance tasks (VM will not resume) which probably invalidates QEMU's File Descriptors.
It's an old BZ.

[libvirt] Unattended guest installation fails
by ChandraShekar Shastri
Hi,
I am following the below link to install a Fedora19 guest on Fedora19 Host.
http://kashyapc.com/2011/08/18/unattended-guest-install-with-a-local-kick...
Version :
libvirtd (libvirt) 1.0.5.1,
QEMU emulator version 1.4.2, Copyright (c) 2003-2008 Fabrice Bellard
I have the iso which I loop mounted and created a http repo using python
module "python -m SimpleHTTPServer". This repo is properly accessible and
the guest is able to pull the initrd.img and vmlinuz but further it fails.
Please find the attached xml and console messages and let me know how to
proceed further.
Thanks,
Chandrashekar
