[libvirt] Interface script for qemu/kvm determinately fails?
by Ryota Ozaki
Hi,
I have a question about interface script (e.g., qemu-ifup) for qemu/kvm.
qemu/kvm is dropped its all capabilities by libcap-ng before executed.
So the script that is executed by qemu/kvm will fail if it executes
privileged operations which are usual jobs of it.
It means we cannot use <script> anymore? or I'm missing something?
I think executing the script in libvirtd after creating a tap and before
dropping capabilities would be a solution for that issue. Am I wrong?
Thanks,

[libvirt] [PATCH] Add virConnectGetLibvirtVersion API
by Cole Robinson
Hi all,
The attached patch adds a new API call for retrieving the libvirt
version used by a connection: virConnectGetLibvirtVersion. Without this,
there is currently no way to determine the libvirt version of a remote
qemu connection for example. This info can be useful for feature
detection/enabling/disabling.
As an example, virt-install may want to use the AC97 sound device as
the default sound model for new VMs. However, this was only added to
libvirt's white list in 0.6.0, while the other models have been
available since 0.4.3. If installing a remote guest, virt-install will
want to ensure that the remote libvirtd is >= 0.6.0. Granted, the remote
version could have backported the AC97 patch and virt-install would be
incorrect, but better to be overly restrictive than to blindly specify
AC97 and have guest creation bomb out.
The 'correct' way to handle the above issue would be some combination of
dropping internal whitelists from libvirt and generating them from info
reported by the hypervisor, and advertising the available values in the
capabilities XML. However I think this API addition makes things more
manageable with little downside until a proper solution is implemented.
Thanks,
Cole

[libvirt] [PATCH] Finer grained migration control
by Chris Lalancette
Normally, when you migrate a domain from host A to host B,
the domain on host A remains defined but shutoff and the domain
on host B remains running but is a "transient". Add a new
flag to virDomainMigrate() to allow the original domain to be
undefined on source host A, and a new flag to virDomainMigrate() to
allow the new domain to be persisted on the destination host B.

[libvirt] Windows VM doesn't start as Linux one does
by Daniel Huhardeaux
Hi,
everything is in the subject. I'm running Debian SID with libvirt-bin
0.7.2-3 and virt-manager 0.8.0-2.
I had 4 VMs created manually some times ago (Lenny, Ubuntu 9.04, W2k and
XPHome) which I migrate to libvirt. Both Linux are booting well, both
Windows not: they start but suddenly reboot.
On W2K I see the white starting bannier increasing on the bottom off the
screen, and when done, reboot.
On XPh at the time where the booting Windows screen should appear, VM
restart. The I get the famous "Windows hasn't shutdown clearly, do you
want to start in safe mode ... aso)
On both systems, after first fail reboot, I can try and try again,
always the same. If I stared VMs manually, no problem!
My start script -which started without any problem my XPHome VM- is:
#!/bin/bash
AUDIO="es1370"
VGA="std"
sudo /usr/bin/kvm -localtime -cdrom /dev/scd0 -boot c -hda
/media/XP/vdisk.img -hdb /media/XP/vdisk1.img -m 512 -soundhw $AUDIO

[libvirt] [PATCH] Fix save and restore with non-privileged guests and SELinux
by Daniel P. Berrange
When running qemu:///system instance, libvirtd runs as root,
but QEMU may optionally be configured to run non-root. When
then saving a guest to a state file, the file is initially
created as root, and thus QEMU cannot write to it. It is also
missing labelling required to allow access via SELinux.
* src/qemu/qemu_driver.c: Set ownership on save image before
running migrate command in virDomainSave impl. Call out to
security driver to set save image labelling
* src/security/security_driver.h: Add driver APIs for setting
and restoring saved state file labelling
* src/security/security_selinux.c: Implement saved state file
labelling for SELinux

[libvirt] [PATCH 0/2] Fix xen domain listing
by Daniel P. Berrange
These patches are a re-post of Jonas Eriksson's work from a couple of months
ago, that we mistakenly forgot to commit.
The first patch is unchanged, apart from being adjusted for new source code
layout. The second patch is changed so that it checks against the hypervisor,
not Xend, since using Xend has a very serious performance impact (as much as
1 second per domain queried has been seen)

Hi all,
On an ubuntu host, I have the network:
virsh # net-dumpxml default

<range start='192.168.122.2' end='192.168.122.254' />
</dhcp>
</ip>
</network>
Would you now some doecumentation on non NATing configuration?
I would like to give my guests public IP adresses.
I create my guests using:
virt-install --connect qemu:///system \
[...] \
--network=network:default
where 'default' is the configuration above.
