[Xen-users] Centos 5.2 using LVM -> DRBD 0.82 -> Xen Problems

Hi Everyone,

I’m trying to get Xen to use a native DRBD device but it seems it will not create the virtual machine. It does not seem to like the DRBD device type, any ideas on what might be wrong?

I’m pretty sure my xen config file is OK and the DRBD device looks fine too.

Full details below.

xm create centostest

Using config file "./centostest".

Error: Device 768 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected.

drbd.conf contents:
