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 David Jaša 2014-02-18 11:22:40 UTC 
Description of problem:
spice-vdagent (session part) exits on client-initiated resolution change

Version-Release number of selected component (if applicable):
guest: spice-vdagent-0.14.0-7.el7.x86_64
host: spice-server-0.12.4-6.el6_5.1.x86_64 (latest RHEL 6.5 version)
client: Fedora 20 (I'll retest later with other clients)

How reproducible:
always

Steps to Reproduce:
1. install a fresh RHEL 7 guest in rhev 3.3, boot to gnome
2. resize client window or go fullscreen or add another monitor
3.

Actual results:
  * resolution remains the same
  * spice-vdagent process exits
  * spice-vdagent process can not be restarted till system-wide
    daemon spice-vdagentd gets restarted
This is what "spice-vdagent -d -d -d -x" prints after resolution changes:
window resize:

  Value in failed request:  0x400
  Serial number of failed request:  86
  Current serial number in output stream:  86



Expected results:
spice-vdagent keeps running and resolution gets resized

Comment 1 Marc-Andre Lureau 2014-02-18 14:01:39 UTC 
It works for me with F20 as host.

What is the version of your kernel?
Is the qxl module loaded? 
What is the version of qemu on host? iirc, there is some support missing there.

I remember Christophe was tracking a similar bug in December. I guess he could help, adding in CC.

3.10.0-88.el7.x86_64

> Is the qxl module loaded? 

yes:
# lsmod | grep qxl
qxl                    69673  2 
drm_kms_helper         52758  1 qxl
ttm                    83948  1 qxl
drm                   297829  4 qxl,ttm,drm_kms_helper

> What is the version of qemu on host?

qemu-kvm-rhev-0.12.1.2-2.415.el6_5.4.x86_64
spice-server-0.12.4-6.el6_5.1.x86_64

> iirc, there is some support missing there.

What extra support is required on _host_ for resolution change of rhel7 guests compared to rhel6 or windows guests?
Comment 3 Marc-Andre Lureau 2014-02-18 16:27:52 UTC 
qemu needs qxl.client_monitors_config support, not sure it is there...

It is not there. This specific crash is fixed by http://lists.freedesktop.org/archives/spice-devel/2014-January/015941.html but then enabling monitors from the guest using xrandr is not working.

Is there a bug for it? I can't see qxl monitor config neither in qemu changelog, nor in bugzilla.
Comment 7 Marc-Andre Lureau 2014-04-09 16:37:14 UTC 
I guess that would be bug 1075139.
