It sees the disk, but no partitions on it. How did you see up
your /sda3/vmdisk2? Are there partitions on it? Did you make sure to
build the kernel with the filesystem support for this (ext2, ext3,
ext4?) Or do you have logical volumes? If so, you need to make
the root option (in you guest configuration file) use your LVM
name, not the disk name. Also this requires turning on the
CONFIG_DM_LINEAR option.
