Just tried it, as well as tried to compile:

python /usr/lib/python2.5/py compile.py *.py

- still getting the same error.

Some debugging shows that - when I run 'xm create test.cfg' - fail comes from /usr/lib/python2.5/site-packages/xen/util/blkif.py


kernel 2.6.24-24-xen

it seems that Xen3.3 in Ubuntu Hardy is missing integration with drbd:

I get -
Error: "Block device must have "phy", "file", or "tap" specified to

VM 'test' has in config file 'drbd' resource as block device.

disk    = ['drbd:test-swap,xvda1,w', 'drbd:test-disk,xvda2,w' ]

Does anybody have success with this type of configuration on Ubuntu

I had the same problems with my block-iscsi script. Maybe the
attached patch will work for you. This works for my paravirtualized
domUs, but not fully virtualized domUs.

How you patched - and compiled? Do I have to get Xen-source from Ubuntu

No, you have to edit a plain text python file,
/usr/lib/python2.5/site-packages/xen/xend/server/blkif.py around
line 59 it should say something like:

if typ not in ('phy', 'file', 'tap'):

Change it to say:

if typ not in ('phy', 'file', 'tap', 'drbd'):

That should at least get you in the right direction if it doesn't
immediately help you.
