make sure your device.map has correct maps (yours look good) then run
grub as follows:
grub --device-map=/boot/grub/device.map
I migrated all my centos 5.5 vms to virtio like that, and it worked
fine. And yes something is not correct with grub and virtio detection on
centos, it works on fedora.

I'm doing some tests in a KVM virtual machine with CentOS 5.5 and it

I've never had any problems with installing grub on virtio. what is in
your /boot/grub/device.map?
# cat /boot/grub/device.map
# this device map was generated by anaconda
(hd0) /dev/vda
In Debian I had no problems, but in CentOS 5.5 I came across this when I
was doing some tests to convert an existing installation in another with
RAID-1.
Thanks for your reply.
