[libvirt-users] Live migration of instance using KVM hypervisor fails
by Gurjar, Unmesh
Hi,
I am trying to migrate a running instance, but it fails with the following error:
$ virsh migrate --live instance-00000008 qemu+tcp://10.2.3.150/system --verbose
error: operation failed: migration job: unexpectedly failed
I can see following in the instance specific qemu log directory (/var/log/libvirt/qemu/instance-00000008.log) on the destination host:

Libvirt version on both hosts:

$ virsh --version

Here are my libvirtd.conf details:

unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "none"
Would be great if someone can point out the issue here.
Note: I have disable apparmor for libvirtd profile and am able to list the instances running on the remote host (from both the servers).

[libvirt-users] No way to obtain guest's cpu and mem usage?
by RaSca
Hi everybody,
I'm using the PHP API to make a web interface interact with the virtual
machines installed on some hypervisor.
Everything is fine, but I would like to find a way to get the guest's
cpu and mem usage, so that it should be possible to make some rrd
graphs. I didn't find out anything and also it seems looking around that
there is no way to obtain those data.
What is strange for me is that programs like virt-top are showing
exactly what I'm looking for. Can anyone help me to find out a way to
retrieve those statistics?
Another related question: do you think I can obtain the same data by
using this:
ps aux | egrep "[/]usr/libexec/qemu-kvm.*libvirt.*" | awk '{print $3"/"$4}'
on the hypervisor? These are related to the kvm process, and the kvm
process IS the virtual machine... Or not?
Thanks to everybody,

[libvirt-users] Libvirtd not starting on reboot
by Shawn Davis
Hello everyone,
I have libvirt and qemu/kvm running on ubuntu 11.10 desktop. Everything is
working great when it is on. The problem is if I reboot, virsh doesn't see
the hypervisor anymore and I can't manually start libvirtd. Libvirtd is
currently located in /usr/sbin/libvirtd and I originally started it with
sudo ./libvirtd -d from that directory. How do I ensure that libvirtd
starts on bootup of the host machine?
Thanks,
Shawn

[libvirt-users] vol-wipe and delete
by Shawn Davis
Hello all,
I know libvirt has the following two commands:
vol-wipe
vol-delete
Can someone please explain to me how these function? Do these only remove
previous session data so that a new virtual instance cannot see it or does
it remove it at the physical level level too so that the data cannot be
found anywhere on the physical drive? I know Eucalyptus and KVM use sparse
files upon instance creation and the instance thinks the ephemeral space is
all zeroes even though it is just sparse. I appreciate any insight in how
the two virsh commands work and if they use zeroes, sparse, or some other
method.
Thanks,
Shawn

[libvirt-users] virsh attach-disk with cache=none and io=native for raw devices (online)
by Frido Roose
Hello,
I see there is an option with virsh attach-disk to set the cache to "none" for raw devices, but I can't find how to attach the disk with io=native (needed for performance reasons).
The goal is to attach a disk online, directly with the proper performance settings.
I know I can set this in virt-manager, but then I have to restart the VM to apply the change, so this is an offline operation.
With virsh edit, I guess I also would have to restart the VM...

[libvirt-users] PCI passthrough error
by Jaap Winius
Hi folks,
Has anyone encountered the following PCI passthrough error?
error: internal error Process exited while reading console \
log output: char device redirected to /dev/pts/1
assigned_dev_pci_read: pread failed, ret = 0 errno = 2
It's produced after I've detached the PCI device from the base OS and
have tried to start up the guest domain.
To get to this point, I mostly followed these instructions:
http://docs.fedoraproject.org/en-US/Fedora/13/html/Virtualization_Guide/c...
The distro I'm using is Debian squeeze, which by default comes with
libvirt 0.8.3 and qemu-kvm 0.12.5, although to avoid a different PCI
passthrough error, I used Debian backports for squeeze to upgrade them
to libvirt 0.9.8 and qemu-kvm 1.0.
The motherboard involved has VT-d support, which I've enabled with the
"intel_iommu=on" kernel option (dmesg shows "Intel-IOMMU: enabled"). I
did not bother with setsebool because SELinux is disabled.
According to lspci, the device I want to pass through to the guest
domain, a USB controller, has bus/slot/function 00:1a.0, so I added
the following stanza to the <devices> section of my guest domain:
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x00'
slot='0x1a' function='0x0'/>
</source>
</hostdev>
Actually, every time I save this configuration, libvirt changes it to:
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x00'
slot='0x1a' function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x05' function='0x0'/>
</hostdev>
Huh, slot 5? I don't have any PCI devices that use slot 5. Well, at
least the system doesn't complain, but I worry that this might be a
symptom of something more serious.
Anyway, I'd be very grateful if anyone has any tips on how I might
avoid the aforementioned error and get PCI passthrough to to work.
Thanks,
Jaap

I have installed parted (GNU parted) 3.0 ( previously it was 1.8.1 .
I have seen that a lot of people have reported this error but no one has

Does anyone remember the solution?
Thanks in advance.

I can also start and stop VMs via virsh.
So the next move for me was to get this working with the java bindings,
libvirt-java. I grabbed libvirt-0.4.7.jar and built it. Eclipse is set up

ran it.

[libvirt-users] NFS + sanlock problems
by Kyrre Begnum
Hello list,
In short: I am experiencing a problem where trying to start a VM which
is allready running on a different libvirt host. Starting it fails,
thanks to sanlock, but the disk dies on the original hypervisor and the
vms filesystem is rendered read-only.
Long version:
i have the following setup:
Two machines (H1 and H2) using CentOS 6.2 with the packages:
qemu-kvm-0.12.1.2-2.209.el6_2.4.x86_64
libvirt-client-0.9.4-23.el6_2.7.x86_64
libvirt-0.9.4-23.el6_2.7.x86_64
libvirt-lock-sanlock-0.9.4-23.el6_2.7.x86_64
They share two NFS folders, one for filesystems ( net set up as a
libvirt storage pool ) and one for sanlock.
sanlock is started without watchdog.
/etc/libvirt/qemu-sanlock.conf:
auto_disk_leases = 1
disk_lease_dir = "/opt/mln/sanlock"
host_id = 51
( host_id is 52 on H2 )
cat /etc/libvirt/qemu.conf | grep sanlock
lock_manager = "sanlock"

I can log in to the VM and everything is fine. Next, i try to start the
VM on H2, i get the following error:
error: Failed to create domain from libvirt/rhel1.locktest.xml
error: internal error Failed to acquire lock: error -243
All seems well, but now the VMs filesystem is in read-only state....
This is the qemu log from H2:

Back on H1 there are multiple lines in the qemu log for the VM:
block I/O error in device 'drive-ide0-0-0': Input/output error (5)

Can someone please help me understand why the filesystem dies on the
original host? Is this an NFS problem? What should I do differently?
Many thanks in advance,
