Description Miroslav Rezanina 2011-02-03 08:37:52 UTC 
Description of problem:
When trying to create hvm guest with cdrom device without specified media, creation fail with "Block device must have physical details specified.". This happens only when xm create is used, with virsh start/virt-manager guest is created successfully.


Version-Release number of selected component (if applicable):
xen-3.0.3-122.el5

How reproducible:
Always

Steps to Reproduce:
1. use disk = [ "...", ",hdc:cdrom,r" ] configuration
2. use xm create to start guest
3. use virsh start to start guest
  
Actual results:
Step 2. fail 

Expected results:
Step 2. succeed

Additional info:
This problem is caused by patch for bz 658712 - Add syntax check for block device. Device uname is "" instead of None so incorrect path is used and error invoked.
