[libvirt-users] SCSI tape drive device
by Tom Stave
I have a SCSI tape backup unit attached to a kvm host managed by
libvirt. Is there a way to expose the SCSI device in libvirt so I could
pass the device to a virtual machine and have the virtual machine
control the tape backup?
Defining the device as a SCSI disk does not appear to work.
In this situation, live migration is not an issue. The VM would always
be tied to this host.

[libvirt-users] libvirt problems. Create bridged network via cmdline?
by Денис Барышев
Hello!
I've faced a weird problem. And I totally can't understand how libvirt
handles networks. The thing that i need to do is simple. I create a bridge
in my ubuntu host, the following config:
*iface eth0 inet manual*
*
*
*auto br0*
*iface br0 inet dhcp*
* bridge_ports eth0*
* bridge_stp on*
* bridge_maxwait 0*
That's OK, and my bridge turns up automatically. But I don't understand why
libvirt can't use it, it always want to create bridge on its own. So that
when I try to create bridged network with the command:
virsh virsh net-create net.xml
net.xml contents:
* <network>*
* <name>virbreth0</name>*
* <bridge name='br0' stp='on' delay='0' />*
* </network>*
I always get error ===>
error: Failed to create network from net.xml
error: cannot create bridge 'br0': File exists
That's pretty obvious that libvirt wants to create bridge on its own. But
what should I do in my specific situation. May be there is a workaround.
I appreciate any help and ideas...
Thanks for your answers.
Best regards,
Denis Barishev.

[libvirt-users] qemu sdl parameters via libvirt
by Bruce Hohl
Hello List, I run a few VMs via libvirt using '--sdl'. I would like
to use qemu parameters -no-quit, -no-frame and -ctrl-grab with
libvirt. Does libvirt support a way to use these qemu parameters?
Does libvirt provide a way to add these options under <graphics/> in
the domain.xml using 'virsh edit domain.xml'?
My current <graphics/> is as follows:
<graphics type='sdl' display=':0' xauth='/home/admin1/.Xauthority'/>
I know I could just create a regular kvm start-up script and include
these parameters but I would like to manages all VMs via libvirt &
virt-manager.
