[Xen-users] creating a DomU from tar
Hi,
I am new with XEN.
I have installed XEN 4 on Debian 6.0.
I am using LVM with XEN.
I created a new DomU with Debian 6.0
Now I am planning a backup solution.
So I made a lvm snapshot:
lvcreate --snapshot --name=samba-snapshot -L 10G
/dev/XEN-Server/vm-samba-disk
after I mounted the snapshot:
mkdir -p /mnt/samba-snapshot
mount /dev/XEN-Server/samba-snapshot /mnt/samba-snapshot
and made a tar archive:
tar -pczf /opt/backups/samba.tar.gz /mnt/samba-snapshot
So far so good.
Now my plan is using the tar archive to create a new DomU.
So I changed the xen-tools.conf using tar instead of debootstrap:
install-method = tar
install-source = /opt/backups/samba.tar.gz
tar-cmd = /bin/tar --numeric-owner -xzvf $sr
The hole xen-tools.conf can be found here:

Now I am trying to create a new DomU with this command:
xen-create-image --size=5Gb --memory=254Mb --hostname=VM-samba-restore
--ip=192.168.255.211
and get the following error:
