Description Luigi Toscano 2011-01-21 15:06:53 UTC

Description of problem:
Recent version of libvirt disabled detection of image type (see RHBZ444583). When no image format is specified, raw format is used. 
Condor used to rely on image autodetection, and it does not allow to specify the format; at this point, only raw images work.

It should be possible to specify the format of disk image(s).

Version-Release number of selected component (if applicable):
RHEL 5.6 (libvirt-0.8.2-15.el5_6.1)
condor-7.4.4-0.17.el5 (and later)

How reproducible:
Submit a job which uses a qcow (or !=raw) image.

Comment 1 Timothy St. Clair 2011-03-11 14:53:35 UTC

Resolution is to append a format to the end.  

VM_DISK=<file>:<drive>:<mode>:<format>

Comment 3 Timothy St. Clair 2011-05-04 16:18:18 UTC

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.
    
    New Contents:
C: Submit a non-raw image which is supported by libvirt
C: Can not startup image 
F: Add submission support for optional :image_format at the end of vm_disk 
R: Allows users to submit multiple formats which are supported by kvm

Comment 4 Luigi Toscano 2011-05-17 16:34:05 UTC

The 4th parameter for VM_DISK is now considered. At this time, the only supported format (apart from raw) is qcow2 for KVM systems.

Verified on RHEL5.6/6.1 KVM x86_64.
condor-7.6.1-0.4
condor-vm-gahp-7.6.1-0.4
