Hmmm... qemu-dm is only used in fully virtualized domUs, right?
I'm having trouble with using drbd devices in xen 3.0.3, I'm wondering
if it is the same issue.
Here are my symptoms:
if I define drbd device as
disk = [ 'phy:/dev/drbd12,sda,w' ]
then it works, but then the device is not put into primary or
secondary mode automatically so the migration does not work
if I define it as
disk = [ 'drbd:resourcename,sda,w' ]
then I get
# xm create xxx -c
Using config file "./xxx".
Traceback (most recent call last):
File "/usr/bin/pygrub", line 650, in ?
fs = fsimage.open(file, get_fs_offset(file))
IOError: [Errno 95] Operation not supported
No handlers could be found for logger "xend"
Error: Boot loader didn't return any data!
if I put a print file before line 650 in pygrub I see that the
resource name is being passed to pygrub instead of device name. If I
hardcode file in pygrub to device name then it works OK.
Is this a bug with xen 3.0.3 that is fixed later or will it work only
if I get the patches from you? ;)
