This should be a regression. I didn't see it in changeset 22653. And it still 
exist latest xen-unstable tree.

No, we don't use stubdoms. This also is a regression. Changeset 22653 didn't 
have this problem.

Here are two questions:
1.Is there new format to set cdrom to disk? It will show the following error 
when I use the default config:
[root@vt-snb3 var]# xl create xmexample.hvm
Parsing config file xmexample.hvm
Unknown disk type: ,hdc

2. If I removing CONFIG_XEN_BLKDEV_BACKEND and CONFIG_XEN_BLKDEV_TAP from dom0, 
when using xm to create qcow guest, it will show VBD error. Also xenu guest 
cannot be boot up successfully. I had reported this issue before, but no 
response.


Best regards
