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
virt-v2v: warning: display <graphics type='sdl'> was ignored when converting rhel5 guest with sdl graphics

Version:
virt-v2v-1.27.60-1.1.el7.x86_64
libguestfs-1.27.60-1.1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare a rhel5 xen guest with sdl graphics.
# virsh dumpxml rhel6.5-test 
    <graphics type='sdl' display='localhost:10.0' xauth='/root/.Xauthority'/>

2.Use virt-v2v to convert the guest,warning info shows:virt-v2v: warning: display <graphics type='sdl'> was ignored
# virt-v2v -ic xen+ssh://10.66.106.64 -os default rhel6.5-test  -on sdl-test  -of qcow2
[   0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 rhel6.5-test
virt-v2v: warning: display <graphics type='sdl'> was ignored
[  16.0] Creating an overlay to protect the source from being modified
[  31.0] Opening the overlay
[  57.0] Initializing the target -o libvirt -os default
[  57.0] Inspecting the overlay
[  67.0] Checking for sufficient free disk space in the guest
[  67.0] Estimating space required on target for each disk
[  67.0] Converting Red Hat Enterprise Linux Server release 6.5 (Santiago) to run on KVM
This guest has virtio drivers installed.
[ 146.0] Mapping filesystem data to avoid copying unused and blank areas
[ 147.0] Closing the overlay
[ 147.0] Copying disk 1/1 to /var/lib/libvirt/images/sdl-test-sda (qcow2)
    (100.00/100%)
[ 288.0] Creating output metadata

3.After conversion,check guest graphics,it defaults to vnc.

Actual results：
Confusing warning info shows:virt-v2v: warning: display <graphics type='sdl'> was ignored

Expected results:
No such warning info shows.

Comment 2 Richard W.M. Jones 2014-10-09 08:48:57 UTC 
Old virt-v2v was a bit confused as to how it handled
<graphics type='sdl'> .  If it saw it in the input, it would
parse it (and not give a warning), but none of the output
drivers would use it -- either it would be ignored or replaced
with spice.

New virt-v2v explicitly warns you that SDL is not going to be
handled.

I think I will make the warning clearer to fix this bug.  The basic
problem however is that SDL is not handled by the old or new virt-v2v.
And indeed cannot be handled because management layers like OpenStack
and RHEV don't work in a way that SDL could work.  SDL is only
relevant if you run qemu directly on your local machine.
Comment 3 Richard W.M. Jones 2014-10-09 09:17:31 UTC 
Upstream fix:
https://github.com/libguestfs/libguestfs/commit/626d85d80be994065951b5f17706ca33ca5fc152

This changes the warning to:

virt-v2v: warning: virt-v2v does not support local displays, so
<graphics type='sdl'> in the input libvirt XML was ignored

which is hopefully clearer.

Tested with:
libguestfs-1.27.61-1.1.el7.x86_64
virt-v2v-1.27.61-1.1.el7.x86_64

# virt-v2v -ic xen+ssh://10.66.106.64 -os default rhel6.5-test  -on sdl-test  -of qcow2

Pool default refreshed

Domain sdl-test defined from /tmp/v2vlibvirt64f57b.xml

[ 320.0] Finishing off

The warning info shows as:
virt-v2v: warning: virt-v2v does not support local displays, so <graphics 
type='sdl'> in the input libvirt XML was ignored

After conversion,the graphics become vnc.
