I am trying to convert a XEN vm to KVM and have followed the SUSE XEN to KVM Guide. When the system starts, it cannot find the vda1 and vda2 disk drives. Also, before this, there is an error which appears regarding xenblk. I have searched all the files mentioned in the guide, and do not have any mention of xenblk or xvda2 within any of them. Any ideas of what I am missing? I am using virtio as per the guide.
