[libvirt-users] hardware error 0x80000021 on Ubuntu 12.10, need advice
by Sebastien Douche
Hi,
On a DELL r610 (Intel Xeon L5520) and a Windows guest I have an
hardware error. The bug is well known[1][2] and seems fixed with the
package 3.5.0-16-generic. But I use 3.5.0-30-generic. Do I need to
upgrade to 13.10? Or just the kernel ? Or modify the options of the
kvm module?
Thanks.

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.

[libvirt-users] USB passthrough not working
by Dale Amon
I just updated an Ubuntu Oneiric to Raring and the VM that works fine on one
fails to start a VM with this passthrough:
<hostdev mode='subsystem' type='usb' managed='no'>
<source>
<vendor id='0x055f'/>
<product id='0x040b'/>
<address bus='3' device='8'/>
</source>
</hostdev>
It just dies at boot time.

[libvirt-users] Two VF cards
by Dominik Mostowiec
Hi,
I try to add 2 VF functions to VM via network.
Livirt networks:
vnet0:
<network>
<name>vnet0</name>
<forward mode='hostdev' managed='yes'>
<pf dev='eth0'/>
</forward>
</network>
vnet1:
<network>
<name>vnet0</name>
<forward mode='hostdev' managed='yes'>
<pf dev='eth1'/>
</forward>
</network>
In VM configuration:
<interface type="network">
<source network="vnet0"/>
<mac address="52:54:0a:b1:48:07"/>
</interface>
<interface type="network">
<source network="vnet1"/>
<mac address="52:54:0a:b1:48:07"/>
</interface>
VM can't start because:
kvm: -device
pci-assign,configfd=24,host=01:10.1,id=hostdev0,bus=pci.0,addr=0x4:
Duplicate ID 'hostdev0' for device
libvirt version 1.0.5.
What i am doing wrong?

[libvirt-users] How to use xl (in place of xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
by Gizmo Chicken
QUESTION: What, if anything, can I do so that I can use xl (in place of
xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
BACKGROUND: I am testing a fully updated (as of March 27) installation of
Ubuntu 13.04 that includes the following packages:
libvirt - version 1.0.2-0ubuntu9
xen-hypervisor-4.2-amd64 - version 4.2.1-0ubuntu1
Upon setting TOOLSTACK=xm in /etc/default/xen (as well as making a few
needed tweaks to /etc/xen/xend-config.sxp), libvirt and virt-manager worked
great. Yippee!
I guess that I should be happy that the xm toolstack still works with Xen
4.2.1 and quit while I'm ahead, but...
According to libvirt's documentation:
"libxl: Starting with Xen 4.2, the legacy XenD/xm toolstack is deprecated
in favor of libxl, also commonly called libxenlight. libvirt supports this
new Xen toolstack via the libxl driver. If XenD is enabled, the legacy xen
driver consisting of the above mentioned channels will be used. If XenD is
disabled, the libxl driver will be used."
See http://libvirt.org/drvxen.html.
In view of the above, I attempted to use xl in place xm by setting
TOOLSTACK=xl in /etc/default/xen. And after doing so (both with and
without, the above mentioned tweaks to /etc/xen/xend-config.sxp), I
recieved the following error when attempting to start virt-manager:
Unable to connect to libvirt.
unable to connect to 'localhost:8000': Connection refused
Verify that:
- A Xen host kernel was booted

Libvirt URI is: xen:///

[libvirt-users] libvirtd using 11GB
by Alex Leonhardt
Hi All,
Am new to this list, and have asked in #ovirt / ovirt-users list and they
pointed me to here ... I've seen libvirtd using ~11 GB of resident memory
after the host has been running for about 60+ days with about 40 VMs
running on it.
The versions I'm currently running are :
libvirt.x86_64 0.9.10-21.el6_3.7
libvirt-client.x86_64 0.9.10-21.el6_3.7
libvirt-lock-sanlock.x86_64
libvirt-python.x86_64 0.9.10-21.el6_3.7
I know I can just restart libvirtd and "all should be fine" (and hopefully
I'll regain the 11GB of memory) - however, is there an updated version that
maybe fixes a memory leak ??
Thanks in advance,
Alex

[libvirt-users] How to see the console output of an EXE session?
by Jon Taylor
Hi,
I am having trouble with a libvirt lxc EXE container which is starting
another EXE container itself, and I need to see the console output of
(hopefully) both containers. How do I do this? I have searched the net a
lot, but the answers I found were either out of date, wrong or didn't work.
Has anyone else here done this?

[libvirt-users] nova compute libvirt driver and libvirt compatibility
by arvind viswanathan
Hi,
>From my reading about nova interface to libvirt, I came to know it uses a
libvirt driver module to communicate with host libvirt. I was wondering if
there are any compatibility matrix available between the nova libvirt
driver and the libvirt installed in the host ?
Thanks

[libvirt-users] connect to esx: Could not find HostSystem with name '(null)'
by Dimitri Nilsen
Hi all,
I am trying to connect to esx vi libvirt 0.10.2.
virsh # connect esx://hostname?no_verify=1&auto_answer=1
error: Failed to connect to the hypervisor
error: internal error Could not find HostSystem with name '(null)'
could you give me a hint, what could be a reason for that problem
in a debug log of libvirt I see:

'/root/.libvirt/auth.conf'
14447: debug : virAuthGetConfigFilePath:86 : Checking for readability of
