[libvirt-users] TUNGETIFF ioctl() failed - virtual machine can't start
by Matthias Meyer
Hi,
I want to migrate from vmware to KVM. Therefore I have installed debian
stable (lenny) and create two virtual machines (KVM).
Both (XP as well as Vista) running fine.
After upgrading to debian testing (sqeeze) both XP-guest as well as
Vista-guest didn't start anymore.
Both are failing during preparation, probably because of a network-problem.
I will give XP as an example:
cat /var/log/libvirt/qemu/devel-xp.log.2
/usr/bin/kvm -S -M pc -m 256 -smp 1 -name devel-xp -monitor
pty -localtime -no-acpi -boot c -drive

char device redirected to /dev/pts/2
info cpus
-> the above will run fine before the upgrade
the following will fail after the upgrade

[libvirt-users] Xen/KVM guest disk sizes
by Tavares, John
I was wondering if there is any way from either the virsh CLI or the libvirt API (preferably virsh) to get the amount of disk space to get the amount of disk space each guest has been assigned??

Lastly, if there is no way to get this information from virsh and/or libvirt, is there a way to figure it out any other way??
Thanks.
John

[libvirt-users] autostarting storage pool

Hello everyone,
How do I make storage pool auto start?
I have:
virsh # pool-list
Name State Autostart
- -----------------------------------------
default active yes
virtimages active no
I don't see anything in pool's xml that could suit this purpose:
virsh # pool-dumpxml virtimages
<pool type='dir'>
<name>virtimages</name>

[libvirt-users] availability of snapshots functionality via Python bindings
by Marcin Krol
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello everyone,
Is this being worked on? I rather need this thing...
Although my system is Debian Lenny, not RH:
kulfon 10.0.0.228 /etc/default % dpkg -l | grep libvirt
ii libvirt-bin 0.4.6-10+lenny1 the
programs for the libvirt library
ii libvirt0 0.4.6-10+lenny1
library for interfacing with different virtualization systems
ii python-libvirt 0.4.6-10+lenny1
libvirt Python bindings
I don't see anything like snapshots available via libvirt.virDomain:
>>> dir(dom0)
['ID', 'OSType', 'UUID', 'UUIDString', 'XMLDesc', '__del__', '__doc__',
'__init__', '__module__', '_conn', '_o', 'attachDevice', 'autostart',
'blockPeek', 'blockStats', 'connect', 'coreDump', 'create', 'destroy',
'detachDevice', 'info', 'interfaceStats', 'maxMemory', 'maxVcpus',
