[libvirt-users] where is the libvirt.xml ?
by suyi wang
Hi all:
My OS is now Fedora16 , and the spice server is installed on it by
rpms. Then I run 'qemu-kvm -hda /root/vaddsoft.img -m 512 -vga qxl -spice
port=5930,disable-ticketing' , I want to find out where is the libvirt.xml
for the command . Well , I mean that the libvirt.xml is genrated
automatically, not by myself manually.
Wish your help! Thanks a lot!

[libvirt-users] tunneled VM migration error
by Shantanu Pavgi
I am getting following error with tunneled migration command:
{{{
$ virsh --connect qemu:///system migrate --verbose --p2p --tunnelled 32 qemu+ssh://kvm-03/system
error: operation failed: Failed to connect to remote libvirt URI qemu+ssh://kvm-03/system
}}}
However I am able to perform other virsh command like list, pool-list, dumpxml using the same remote libvirt URI:
{{{
$ virsh --connect qemu+ssh://kvm-03/system list
}}}
Also, the hypervisor native migration is working fine with following command:
{{{
$ virsh --connect qemu:///system migrate 31 qemu+ssh://kvm-03/system
}}}
I am confused why remote URI worked for some of the commands but not for the migrate command. Am I missing something with the tunneled migration command or libvirtd/qemu configuration file? Any help would be appreciated.
Software versions on both systems:
* CentOS 6.2
* Libvirt 0.9.4
* qemu-kvm 2:0.12.1.2-2.209.el6_2.4

[libvirt-users] Correctly using libvirt to mount /dev/pts and /dev in an lxc application container
by David Jablonski
We would like to mount /dev and /dev/pts correctly using the libvirt xml
config file instead of doing a bind mount in a container init script we use.
Currently the container config is:
<domain type='lxc'>
<name>CentOS_57</name>
<uuid>ff5d3c04-49e6-a3cc-0a14-ff13625eca3c</uuid>
<memory>262144</memory>
<currentMemory>262144</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='i686'>exe</type>
<init>/bin/lxc-progs</init>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<filesystem type='mount' accessmode='passthrough'>
<source dir='//home'/>
<target dir='/home'/>
</filesystem>
<filesystem type='mount' accessmode='passthrough'>
<source dir='/archive/centos57-root'/>
<target dir='/'/>
</filesystem>
<filesystem type='mount' accessmode='passthrough'>
<source dir='//archive'/>
<target dir='/archive'/>
</filesystem>
<console type='pty'>
<target type='serial' port='0'/>
</console>
</devices>
</domain>
The /bin/lxc-progs file is:
#!/bin/sh
service rsyslog start
service sssd start
service sshd start
mount -t devtmpfs none /dev
mount -t devpts none /dev/pts
mount -t tmpfs none /dev/shm
exec /bin/sh
Basically how do we remove the above mount points in the lxc init
process and use libvirt to control the mounts instead?
Any help would be appreciated. Thank you.

This tells the "lsi" device is not supported by
your qemu. You must configured scsi device in
domain XML, and "lsilogic" is the default controller
model if you don't configure it. see

[libvirt-users] libvirt for spice
by suyi wang
Hi all:
I tried kvm on my ubuntu with the libvirt.xml file as follows:
<domain type='kvm'>
<name>instance-00000011</name>
<memory>2097152</memory>
<os>
<type>hvm</type>
<boot dev="hd" />
</os>
<features>
<acpi/>
</features>
<vcpu>1</vcpu>
<devices>
<sound model='ac97'/>
<input type='tablet' bus='usb'/>
<disk type='file'>
<driver type='qcow2'/>
<source
file='/opt/stack/nova/nova/../
/instances/instance-00000011/disk'/>
<target dev='vda' bus='ide'/>
</disk>
<disk type='file'>
<driver type='qcow2'/>
<source
- Ignored:
file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/>
<target dev='vdb' bus='ide'/>
</disk>
<interface type='bridge'>
<source bridge='br100'/>
<mac address='02:16:3e:44:a1:dd'/>
<filterref
filter="nova-instance-instance-00000011-02163e44a1dd">
<parameter name="IP" value="10.0.0.2" />
<parameter name="DHCPSERVER" value="10.0.0.1" />
</filterref>
</interface>
<!-- The order is significant here. File must be defined first
-->
<serial type="file">
<source
path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/>
<target port='1'/>
</serial>
<console type='pty' tty='/dev/pts/2'>
<source path='/dev/pts/2'/>
<target port='0'/>
</console>
<serial type='pty'>
<source path='/dev/pts/2'/>
<target port='0'/>
</serial>
<graphics type='vnc' port='-1' autoport='yes' keymap='en-us'
listen='0.0.0.0'/>
</devices>
</domain>
So it works well.
Howerver, I want change the remote access method by spice, I simply
changed
the libvirt.xml as follows:
<domain type='kvm'>
<name>instance-00000011</name>
<memory>2097152</memory>
<os>
<type>hvm</type>
<boot dev="hd" />
</os>
<features>
<acpi/>
</features>
<vcpu>1</vcpu>
<devices>
<sound model='ac97'/>
<input type='tablet' bus='usb'/>
<disk type='file'>
<driver type='qcow2'/>
<source
file='/opt/stack/nova/nova/..//instances/instance-00000011/disk'/>
<target dev='vda' bus='ide'/>
</disk>
<disk type='file'>
<driver type='qcow2'/>
<source
file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/>
<target dev='vdb' bus='ide'/>
</disk>
<interface type='bridge'>
<source bridge='br100'/>
<mac address='02:16:3e:44:a1:dd'/>
<filterref
filter="nova-instance-instance-00000011-02163e44a1dd">
<parameter name="IP" value="10.0.0.2" />
<parameter name="DHCPSERVER" value="10.0.0.1" />
</filterref>
</interface>
<!-- The order is significant here. File must be defined first
-->
<serial type="file">
<source
path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/>
<target port='1'/>
</serial>
<console type='pty' tty='/dev/pts/2'>
<source path='/dev/pts/2'/>
<target port='0'/>
</console>
<serial type='pty'>
<source path='/dev/pts/2'/>
<target port='0'/>
</serial>
<graphics type='spice' port='-1' autoport='yes' keymap='en-us'
listen='0.0.0.0'/>
</devices>
</domain>
As you can see, I just change <graphics type='vnc' port='-1'
autoport='yes'
keymap='en-us' listen='0.0.0.0'/> to <graphics type='spice' port='-1'
autoport='yes' keymap='en-us' listen='0.0.0.0'/> , But it called the
error as follows:
libvirtError: internal error Process exited while reading console log
output: char device redirected to /dev/pts/12
TRACE: do_spice_init: starting 0.8.1
TRACE: do_spice_init: statistics shm_open failed, Permission denied"
I wish someone can give me some help! Thanks!

I have a rhel6.0 server running kvm. I have recently needed to add additional cpu's to some of the guests but cannot do it via virt-manager, can't doit using virt, and can't do it by vi the guest.xml file. Is this a bug or am I missing something?
