I create a domU in an LVM using virt-install (CentOS current). The installation goes as expected and all is well.

I thought that I would be able to mount this file system like so:

mount -o loop /dev/VolGroup00/vm_name /mnt/image

...yet I cannot, it tells me I have to provide the filesystem type. When I do (ext3), that fails telling me it can't find a valid block device.

Can someone point out what I have done wrong?

The virtual disk has a partition table -- use losetup and kpartx like this:

   losetup /dev/VolGroup00/vm_name
   kpartx -av /dev/loopN

where /dev/loopN is the device created by losetup.

I think that's the right syntax -- check the manual pages for details. (And just in case you think it is, kpartx is nothing to do with X or KDE.)
