Description Chris Lalancette 2006-11-13 11:25:28 EST
Description of problem:

blktap doesn't tell you if your disk image file doesn't exist which can confuse
users as the domain starts, but doesn't find the root device.

Version-Release number of selected component (if applicable):
xen-3.0.3-3 (although I looked at current CVS as of 11/13, and the fix is not in
there, either).

IBM also provided the upstream changeset that fixes this:  12322:d173b32f54ab
I'll attach the patch.

Comment 5 Konrad Rzeszutek 2006-12-11 17:56:02 EST

Is there anything IBM can do to help get this fixed?

Comment 9 Jay Turner 2007-05-09 15:32:49 EDT
QE ack for RHEL5.1.  Straightforward to test.
Comment 10 Daniel Berrange 2007-06-15 20:28:43 EDT
This is now built into xen-3.0.3-29.el5  in dist-5E-qu-candidate. To test try

 - Create a VM config file with a single disk backed by a file & using tap:aio:
 - In the 'disks' config line, insert a delibrate typo in the disk filename
 - Try to start the guest

A friendly error message should be displayed and the guest should not start.
