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.

Fixed In Version: libguestfs-1.36.1-1.el7
Doc Type: Bug Fix
Doc Text:
Cause: when exporting guests to Glance, virt-v2v did not set the hw_video_model property of images. Consequence: Nova does not configure the guest to use the correct video model (QXML, for example). Fix: virt-v2v set the hw_video_model property with the proper video model. Result: in OpenStack, the guest is configured to use its video model.

404 Not Found: No image found with ID esx6.0-win7-x86_64 (HTTP 404)
virt-v2v: warning: glance: failed to set image properties (ignored)
[ 800.9] Finishing off
Image properties:
  --min-ram 4096
  --property 'os_version'='6.1'  --property 'hw_disk_bus'='virtio'  --property 'hw_vif_model'='virtio'  --property 'architecture'='x86_64'  --property 'hypervisor_type'='kvm'  --property 'vm_mode'='hvm'  --property 'os_type'='windows'  --property 'os_distro'='windows'

2.After conversion, lanuch the win7 instance using the image in openstack and checkpoint for win7 guest, but find that qxl driver can't installed for display device and  pls refer to screenshot

3.Check xml of win7 guest in openstack server, win7 guest has vnc+cirrus graphic mode as below
# virsh dumpxml instance-0000001f
<domain type='kvm' id='33'>
  <name>instance-0000001f</name>
..... 
 <graphics type='vnc' port='5903' autoport='yes' listen='0.0.0.0' keymap='en-us'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>
    <video>
      <model type='cirrus' vram='16384' heads='1'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>
....

4.But check that v2v has set qxl for guest video in v2v conversion log, details pls refer to attachment log, but openstack still set cirrus for guest video.that it is the reason why can't install qxl driver for display device in win7 guest

libguestfs: trace: v2v: pwrite_device = 2
gcaps_block_bus = virtio
gcaps_net_bus = virtio-net
gcaps_video = qxl
gcaps_arch = x86_64
gcaps_acpi = true


 
Actual results:
As above description

Expected results:
Can install qxl driver for display device in win7 guest after converting to glance by virt-v2v

I asked Ming Xie to file this RFE.  However I'm not clear if
OpenStack can actually support QXL/Spice now.  If it can now do
that, then please reassign this bug to RHEL 7 -> libguestfs.

Richard, 

QXL itself is supported with native clients.
However, since we have removed the spice-HTML5 client users have no simple way to connect to the guest. Users can use the native spice client to directly connect to the host.

It seems that --property hw_video_model=qxl is missing from the Image properties, there nova doesn't set the guest to use qxl..

Thanks,
Vladik

[1461.7] Finishing off

2.After conversion, launch the win7 instance using the image in openstack

3.Checkpoints for win7 guest are passed except that graphic driver is still VGA after restarting guest according to reminder

4.Right click the display device and manual update display driver from VGA to qxl successfully

Additional info
1.Also could reproduce the problem of step3 on win2008r2 guest


Hi rjones,

The problem of step 3 may be same as bug 1356550, and I also verified the bug 1356550, the display of win7 still can't be updated to qxl driver automatically after converting the guest from kvm to rhv,so the bug1356550 has not been fixed yet, could I move this bug to verified status because of problem of step3 is a known bug
Comment 11 Richard W.M. Jones 2017-03-13 16:46:38 UTC 
The fix here was to pass this property to glance:

> | hw_video_model   | qxl                                  |

As that is being done, this bug is *verified*.

Now as you say, it may also be that we aren't installing the qxl
driver for Windows 7, causing the problematic step 3.  That is
another bug, likely bug 1356550 which you linked to.
Comment 12 mxie@redhat.com 2017-03-14 02:03:07 UTC 
According to the comment 10 and comment 11, move this bug from ON_QA to VERIFIED
