Details:

Hello.

I tried to install grub2 on my virtual machine which uses Virtio as an
emulation layer for devices.

This is what I got:

Setting up grub-pc (1.98+20100804-14) ...

Creating config file /etc/default/grub with new version
error: cannot seek `/dev/vda'.
error: cannot seek `/dev/vda'.
/usr/sbin/grub-probe: error: cannot seek `/dev/vda'.

And now what grub-probe says:
