I have created a guest using virt-install.
On the dom0 we have created a LogicalVolume and used it to install the guest

We need to copy all the contents of the guest, so we'd like to access 
the guest filesystem from dom0

Tried something like :
mount -o loop /dev/xenvps/mylv /mnt

But it doesn't work
    

Omit "-o loop". /dev/xenvps/mylv is a (symlink-to) a real block device
file, so there's no need for loop.

Keep in mind that having it mounted R/W in guest and R/W or R/O in dom0
at the same time is asking for trouble.

  
It doesn't work

# mount /dev/mapper/xenvps-centos45 /mnt/
mount: you must specify the filesystem type
