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.

Description of problem:
error shows when changing video from qxl to other models
Version-Release number of selected component (if applicable):
# rpm -qa libvirt qemu-kvm virt-manager kernel
kernel-3.7.0-0.36.el7.x86_64
virt-manager-0.9.4-4.el7.noarch
libvirt-1.0.3-1.el7.x86_64
qemu-kvm-1.4.0-1.el7.x86_64
Reproduce steps:
1. prepare a guest with a qxl video device, guest xml like:
<video>
<model type='qxl' ram='65536' vram='65536' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>

Error changing VM configuration: XML error: ram attribute only supported for type of qxl
Actual results:
As steps.
Expected results:
Step 2 should work well and delete <ram> element automaticly when change models.

--- Additional comment from Martin Kletzander on 2013-03-14 11:08:24 EDT ---
This is cause by the wrong use of 'ram' instead of 'vram' and recent change in libvirt, should be trivial to fix.

I can reproduce this bug:
Version:
virt-manager-0.9.0-18.el6.x86_64
libvirt-0.10.2-18.el6_4.9.x86_64
Steps for Reproduce:
1. prepare a guest with a qxl video device, guest xml like:
<video>
<model type='qxl' ram='65536' vram='65536' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
2. # virt-manager, select video device from the guest, and change model from qxl to others.
Result:
After step 2, get error:
Error changing VM configuration: XML error: ram attribute only supported for type of qxl
Verify:
libvirt-0.10.2-21.el6.x86_64
virt-manager-0.9.0-19.el6.x86_64
Steps for Verify:
1. prepare a guest with a qxl video device, guest xml like:
<video>
<model type='qxl' ram='65536' vram='65536' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
2. # virt-manager, select video device from the guest, and change model from qxl to others.
Result:
After step 2, guest works well and delete <ram> element automaticly when change models.
