I'm using ruby 1.8.7 and going to port to ruby 1.9. I'd like to confirm whether the libvirt ruby support the latest ruby 1.9. Thanks.

[libvirt-users] SCSI tape drive device
by Tom Stave 01 Nov '10

01 Nov '10

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 01 Nov '10

01 Nov '10

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 31 Oct '10

31 Oct '10

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.
