612842 – [virt-convert] convert xml doesn't support qcow,qcow2,cow format

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Version-Release number of selected component (if applicable):
-libvirt-0.8.1-13.el6.x86_64
-qemu-kvm-0.12.1.2-2.90.el6.x86_64
-qemu-img-0.12.1.2-2.90.el6.x86_64
-kernel-2.6.32-42.el6.x86_64
-libvirt-python-0.8.1-13.el6.x86_64

How reproducible:
5/5

Steps to Reproduce:
1.
# cat virt_image.xml 
           <image>
             <name>demo</name>
             <domain>
               <boot type="hvm">
                 <guest>
                   <arch>x86_64</arch>
                 </guest>
                 <os>
                   <loader dev="hd"/>
                 </os>
                 <drive disk="mydisk" target="hda"/>
               </boot>
               <devices>
                 <vcpu>1</vcpu>
                 <memory>262144</memory>
                 <interface/>
		 <graphics/>
               </devices>
             </domain>
             <storage>
               <disk id="mydisk" file="RHEL-Server-6-64-virtio.qcow2" use="system" format="qcow2"/>
             </storage>
           </image>

2.
# qemu-img info RHEL-Server-6-64-virtio.qcow2 
image: RHEL-Server-6-64-virtio.qcow2
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 971M
cluster_size: 4096

3.
# virt-convert -i virt-image -o vmx virt_image.xml 
ERROR    Couldn't import file "virt_image.xml": Unable to determine disk format
  
Actual results:
  I tried the 'qcow2' and 'qcow' format and get the same result:
ERROR    Couldn't import file "virt_image.xml": Unable to determine disk format
  

Expected results:
 virt-convert command support virt-image format convert to other format.

Additional info:

 I try to change the format in the xml file use that:
"<disk id="mydisk" file="RHEL-Server-6-64-virtio.qcow2" use="system" format="raw"/>" and  <disk id="mydisk" file="test.qcow" use="system" format="raw"/>.

Setps
1. 
# virt-convert -i virt-image -o vmx virt_image.xml 
Generating output in 'vmx' format to demo/
Converting disk 'RHEL-Server-6-64-virtio.qcow2' to type vmdk...
Done.

# virt-convert -i virt-image -o vmx virt_image.xml 
Generating output in 'vmx' format to demo/
Converting disk 'test.qcow' to type vmdk...
Done.

For the above steps, virt-convert can support qcow2/raw/qcow convert to vmdk. xml format = ?,maybe need to add some options support qcow2/qcow format.

Comment 2 RHEL Program Management 2010-07-15 14:54:30 UTC

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Comment 3 Cole Robinson 2010-08-06 18:27:37 UTC

virt-image / virt-convert aren't really high priority items, so just deferring to 6.1 since we are this late in the cycle.

Comment 4 Cole Robinson 2010-12-08 01:24:16 UTC

Thanks for the report, fixed upstream now:

http://hg.fedorahosted.org/hg/python-virtinst/rev/27a536f58932

Though COW format is not included since this isn't currently supported by virt-image, and is barely used in the wild anyways.
