Hi all,
after installing debian wheezy I'm running a clonezilla virtual
machine to clone some computer harddrives. Unfortunately the
data transfer breaks during the backup and the restore process
and it's not possible to connect to the VM over ssh or with a vnc
client. I tried all the virtual network cards and the only
improvement seems to be a _change_ of the nic after a shutdown.
However, this only delays the vm not reachable state.
Is there a way to locate the error?
I cannot find anything suspicious in the logs of the server or the
vm. I experienced the same behaviour in lenny 32bit environment. Is
there a way to isolate the problem?
Georg
