[libvirt-users] behaviour of "virsh shutdown domainName"
by Jorge Somavilla
Hi all,
I am experiencing some problems with different versions of libvirt
(0.7.5 and 0.7.7), with a kvm (WinXP), host running Ubuntu 9.10, and i
would like to ask you two questions:
- In virsh, after running the command "shutdown domainName", what
should be the final state of the domain, if the shutdown finishes
correctly: "shutoff", "no-state", "inactive", or the domain shouldn't
show in "list --all" (full clean-up)?
- After the command "shutdown domainName", should i be able to run the
command "start domainName", without first defining the domain? (i.e.:
does shutdown "undefine" the domain?).
In my experience 0.7.5 used to leave the shut down domains as defined,
so i could run "start" right after. Testing in other hosts this
doesn't work always like that, and even if the domain apparently shuts
down correctly, the domain sometimes shows in "list --all", and
sometimes it doesn't. With libvirt 0.7.7 the domain never shows in
"list --all" after a successful shutdown, which makes me think it was
a bug and it has been corrected. Am i missing anything?
Any help would be much appreciated, thanks in advance.
Jorge Somavilla.

[libvirt-users] Duplicate USB vendor,product specification
by Don Morrison
I studying how to attach USB devices to a KVM guest virtual machine using
libvirt. Using the "vendor" and "product" to specify the source device
seems like a good option since the "bus" and "device" values can change as
a device is removed and re-inserted. The question I have is what should I
expect to happen if I plug in two identical USB devices - so they have the
same vendor/product information? There is nothing in the documentation on
libvirt.org to address this case. Thanks.

[libvirt-users] Memory domain
by angelo alfano
1. Can I set the memory of a domain when it is running?
2. If the host has a total memory of 2GB and launch two VM which respectively 2GB of memory setting, because I don't have a mistake o warning?

[libvirt-users] Regarding SPICE
by anuj rampal
Hi,
I have set up KVM on FC12.
I was wondering if its possible to Display the VM using spice + libvirt?
As in, if I can define my domain with graphics like:
<graphics type='spice' port='-1' autoport='yes' listen='0.0.0.0'/>
or
<graphics type='spice' port='5903' ' listen='0.0.0.0'/>
Thanks & Regards

[libvirt-users] Problem with libvirt migration
by Daniel Bidwell
I have two hosts, vm1 and vm2, which are both running libvirt 0.7.0.
They share a common ocfs2 file system that resides on a san, and have
identical network configurations. I am running qemu-kvm 0.11.0 on
ubuntu 9.10 servers.
I start base32 on vm1 and it comes up (it also runs fine if started on
vm2). Then from vm2 I do:
vm2#: virsh -c qemu://vm1/system
migrate --live base32 qemu://vm2/system
The migration starts and the vm2 virsh returns to the prompt. vm2 shows
base32 as running and vm1 shows base32 as stopped. The console for
base32 on vm2 is frozen and unresponsive.
I have the debug level set to 1 on both machines.
This is an excerpt from the virsh.log file from vm1:

[libvirt-users] ESX support
by Jonathan Kelley
Just curious but how long has ESX support been in libvirt?
Also I noticed this error when accessing one of my windows vms:
error: internal error Expecting VMX entry 'scsi0.virtualDev' to be
'buslogic' or 'lsilogic' but found 'lsisas1068'
Not sure whether this is an enhancement, defect, or not supported at this time.
Thanks.

[libvirt-users] unable to get domain list of KVM guests from libvirt as non-root user
by Tom Georgoulias
I have a python script that monitors the guest VMs on a servers running
Xen, but the script doesn't work properly on a server I just built with
KVM. The script runs as a non-root user (same on all servers) and
simply gathers some details on the status and names of the domains
running on the host.
The Xen and KVM servers are running CentOS 5.4 x86_64 and are using the
same version of libvirt:
libvirt-0.6.3-20.1.el5_4
libvirt-python-0.6.3-20.1.el5_4
Both Xen and KVM servers have the default libvirt.conf config file and
the following /var/run/libvirt permissions:
KVM:
[root@kvm ~]# ls -l /var/run/libvirt
total 16
srwx------ 1 root root 0 Mar 12 08:37 libvirt-sock
srwxrwxrwx 1 root root 0 Mar 12 08:37 libvirt-sock-ro
drwxr-xr-x 2 root root 4096 Mar 8 13:05 network
drwxr-xr-x 2 root root 4096 Mar 11 16:17 qemu
Xen:
[root@xen ~]# ls -l /var/run/libvirt
total 16
srwx------ 1 root root 0 Feb 5 08:53 libvirt-sock
srwxrwxrwx 1 root root 0 Feb 5 08:53 libvirt-sock-ro
drwxr-xr-x 2 root root 4096 Jan 21 14:38 network
drwxr-xr-x 2 root root 4096 Oct 20 18:50 qemu
Kernel/hypervisor versions of Xen and KVM servers:
kernel-xen-2.6.18-164.9.1.el5
xen-3.0.3-94.el5_4.2
kvm-83-105.el5_4.27
kvm-qemu-img-83-105.el5_4.27
kernel-2.6.18-164.11.1.el5
To troubleshoot, I've been running python interactively as the non-root
user. Here's how my Xen servers behave:
[testu@xen ~]$ python
Python 2.4.3 (#1, Sep 3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libvirt
>>> conn = libvirt.openReadOnly(None)
>>> domains = conn.listDomainsID()
>>> print domains
[0, 3, 15, 16, 21, 24, 26, 30, 32, 36, 38, 41, 43, 45, 47, 49, 51, 55,
63, 67]
>>>
When I try the same thing on the KVM server:
[testu@kvm ~]$ python
Python 2.4.3 (#1, Sep 3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libvirt
>>> conn = libvirt.openReadOnly(None)
14:33:07.303: error : No vport operation path found for host0
14:33:07.320: error : No vport operation path found for host4
14:33:07.325: error : No vport operation path found for host3
14:33:07.367: error : No vport operation path found for host1
14:33:07.368: error : No vport operation path found for host2
>>> domains = conn.listDomainsID()
>>> print domains
[]
>>>
However, when logged in as root on the KVM server, it works just like my
Xen servers:
[root@kvm ~]# python
Python 2.4.3 (#1, Sep 3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libvirt
>>> conn = libvirt.openReadOnly(None)
>>> domains = conn.listDomainsID()
>>> print domains
[1]
As an experiment suggested by a someone on the centos-virt list, I
modified the ownership and permissions of the socket files in
/etc/libvirt/libvirtd.conf to use the same user running the python
script. That didn't make a difference.
[testu@kvm ~]$ ls -l /var/run/libvirt
total 16
srwxrwx--- 1 root testu 0 Mar 12 07:45 libvirt-sock
srwxrwxrwx 1 root testu 0 Mar 12 07:45 libvirt-sock-ro
drwxr-xr-x 2 root root 4096 Mar 8 13:05 network
drwxr-xr-x 2 root root 4096 Mar 11 16:17 qemu
[testu@kvm ~]$ python
Python 2.4.3 (#1, Sep 3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libvirt
>>> conn = libvirt.openReadOnly(None)
07:45:56.893: error : No vport operation path found for host0
07:45:56.912: error : No vport operation path found for host4
07:45:56.919: error : No vport operation path found for host3
07:45:56.967: error : No vport operation path found for host1
07:45:56.968: error : No vport operation path found for host2
>>> domains = conn.listDomainsID()
>>> print domains
[]
>>>
Can someone give me some pointers on what to check next? I'm running
out of ideas.
Thanks,

[libvirt-users] Problems with a logical pool creation
by Rubén Vejabalbán
Hi all,
I am new in virtualization so forgive me any evidence.
After pool definition, when I try to create a logical pool I obtain the
following error:
# virsh pool-define vms.pool.xml
> Pool vms.pool defined from vms.pool.xml
>
> # virsh pool-start vms.pool
> error: Failed to start pool vms.pool
> error: internal error '/sbin/vgchange -ay vms.pool' exited with non-zero
> status 5 and signal 0: Volume group "vms.pool" not found
>
Is anything wrong with my xml file?
<pool type="logical">
> <name>vms.pool</name>
>
<source>
> <device path="/dev/sda2"/>
> </source>
> <target>
> <path>/var/lib/virt/images</path>
> </target>
> </pool>
>
Are pools created in this way permanent?
Thank you!

[libvirt-users] LXC: unable to configure networking for LXC
by Avi Weit
Hello,
I would like to set up sshd under an LXC application container and to be
able to connect into it from the host. I was able to achieve that with LXC
tools CLI after setting up a bridge via brctl and creating a proper
lxc.conf file for lxc-execute to use. However, I am unable to do so via
libvirt. I am using libvirt version 0.7.1 installed on fedora 12.
I first verified that the default network is up
[root@enc12 avi]# virsh net-list --all
Name State Autostart
-----------------------------------------
default active yes
and that the bridge exists
[root@enc12 avi]# brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.000000000000 yes
I then went over the explanations under
http://www.libvirt.org/formatdomain.html#elementsNICS and
http://wiki.libvirt.org/page/Networking
and made sure net.ipv4.ip_forward = 1 under file /etc/sysctl.conf on the
host
after that, I created a container with the following xml specification:
<domain type='lxc'>
<name>ssh9</name>
<memory>500000</memory>
<os>
<type>exe</type>
<init>/usr/sbin/sshd</init>
</os>
<vcpu>1</vcpu>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<interface type='network'>
<source network='default'/>
</interface>
<console type='pty' />
</devices>
</domain>
Below is the command that verifies LXC is running followed by dumpxml:
[root@enc12 avi]# virsh -c lxc:/// list --all
Id Name State
----------------------------------
1551 ssh9 running
<domain type='lxc' id='1551'>
<name>ssh9</name>
<uuid>ead3dc4f-9b3f-eec0-e83a-1d87e0ffb1eb</uuid>
<memory>500000</memory>
<currentMemory>500000</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686'>exe</type>
<init>/usr/sbin/sshd</init>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<interface type='network'>
<mac address='52:54:00:e8:e3:dd'/>
<source network='default'/>
<target dev='veth0'/>
</interface>
<console type='pty' tty='/dev/pts/1'>
<source path='/dev/pts/1'/>
<target port='0'/>
</console>
</devices>
</domain>
However, I can not see the IP address of the container so was not able to
connect it. I can also see that the routing table configured on the host -
routes any address destined to network 192.168.122 - into the bridge and I
understood that the container should have constructed with one of the IPs
in the range of 192.168.122.2 to 192.168.122.254 (as defined in dhcp tag
under default network) but it did not happen.
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
9.148.28.32 * 255.255.255.240 U 1 0 0
eth0
192.168.122.0 * 255.255.255.0 U 0 0 0
virbr0
default 9.148.28.33 0.0.0.0 UG 0 0 0
eth0
I wonder what am I missing here.
Thanks,
- Avi
