Hello Peter, hello list
yes I do the 'dd' on the Xen guest/ duomU.
why do you ask ?
Meanwhile I tried to take another NIC for the drbd/heartbeat cross
connection (have the drbd cluster on two Sun X2100M2 which has 2
Broadcom and two Nvidia NIC), but switching on the Nvidia NIC did not
solve the problem.
Now I think about, to setup LVM on/over drbd (because Florian Haas told
that Xen with loop/img files is not recommended)
and setup a LV for each domU.
Any experiences about that ?
