libvirtError: internal error unsupported disk type 'vda'


Hi everyone,

I am creating VM on my host Centos 5.4 (Ubuntu as a VM) ..

When i execute command :

virt-install --connect qemu:///system -n r1u1 -r 1024 --disk vol=rf/r1u1 --disk path=/home/devang/ubuntutest.iso,device=cdrom,bus=ide,perms=ro --vnc --noautoconsole os-type linux --os-variant ubuntujaunty --accelerate


Here ----
rf - Volume Group defined using "Virsh pool-define-as" Command

r1u1 - Logical Volume on that Volume Group 'rf'

ubuntutest.iso -- This iso contain my own created Preseed.cfg file in initrd


I got following error:

Starting install...
internal error unsupported disk type 'vda'
Domain installation may not have been
successful. If it was, you can restart your domain
by running 'virsh start r1u1'; otherwise, please
restart your installation.

self.domain = self.conn.createLinux(install_xml, 0)

if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)
libvirtError: internal error unsupported disk type 'vda'




So if u have any suggestions to overcome this problem...... and if u have proper steps to perform Ubuntu Preseed installation then plz share with us.........

Thanks in advance............

vda is what the virtio_blk disks are called in linux (instead of sdX/hdX). I usually start my VMs with if=virtio
