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 Milan Barta 2013-08-06 12:58:35 UTC 
Description of problem:
VM fails to shutdown correctly when running it with Spice QXL driver. The VM freezes and never shuts down completely. This is reproducible 75 % of the time.

When qemu-kvm is executed with different -vga parameter (tested with 'cirrus'), the VM shuts down 100 % of the time correctly.

Version-Release number of selected component (if applicable):
Host & client: RHEL 7
Guest: RHEL7, (Fedora 19)

qemu-kvm-1.5.2-2.el7.x86_64
spice-server-0.12.4-1.el7.x86_64

xorg-x11-drv-qxl-0.1.1-0.13.20130703git8b03ec16.el7.x86_64
virt-viewer-0.5.7-1.el7.x86_64
spice-gtk-0.20-2.el7.x86_64
spice-vdagent-0.14.0-3.el7.x86_64

How reproducible:
75 %

Steps to Reproduce:
1. run a VM with qxl graphics driver (e.g. see qemu-kvm command below)
2. initiate shutdown from within the guest system

Actual results:
Guest hangs on shutdown.

Expected results:
Guest system shuts down completely and correctly.

Additional info:

qemu-kvm command:
/usr/libexec/qemu-kvm -m 768 -name r7 -drive file=/home/mbarta/rhel7.img,if=virtio -vga qxl -spice port=5901,addr=127.0.0.1,disable-ticketing,image-compression=off,streaming-video=off,playback-compression=off -device virtio-serial-pci -device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 -chardev spicevmc,id=spicechannel0,name=vdagent -device intel-hda -device hda-duplex

Comment 4 Søren Sandmann Pedersen 2014-01-10 19:31:10 UTC 
Doesn't reproduce for me with RHEL 7 guest on RHEL 7 host, both as of approximately Beta1.

Does this still reproduce with a more recent RHEL 7?
Comment 5 Milan Barta 2014-01-21 11:02:50 UTC 
With RHEL7 Beta 1, I couldn't reproduce either. Looks like it's been fixed.
