Priority: medium
Bug ID: 78541
Assignee: dri-devel@lists.freedesktop.org
Summary: QXL DRM Driver Freezes QEMU KVM Guest when Switching
to Text Console
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: reimth@gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: DRI CVS
Component: DRM/other
Product: DRI
Host:
- Debian Linux with kernel 3.11-2-amd64
- QEMU emulator version 1.7.0 (Debian 1.7.0+dfsg-2)
- Spice server 0.12.4
- libvirt Virtual Machine Manager 0.9.5
Guest:
- Ubuntu Saucy with kernel 3.11.0-20-generic
Reproduce:
- Start qemu with option -global qxl-vga.revision=4, which allows drm to load
the
qxl driver
Other parameters related to graphics:
+ -device
qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,bus=pci.0,addr=0x2
+ -spice port=5900,addr=127.0.0.1,disable-ticketing,seamless-migration=on
+ -chardev spicevmc,id=charchannel0,name=vdagent
+ -device
virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0
- Check with dmesg, that QXL DRM has been correctly initialised
- Send Ctrl-Alt-Fn (n = 1, 2, ...) to VM guest
Bug:
Virtual machine manager will switch to console but freezes with strange
display. Guest cannot be contacted any more. Switching back to vc is not
possible. ssh connections will hang. No netconsole output. The guest must be
restarted using forced shutdown.
The problem occurs also for qemu 2.0. It does not occur, if only userspace
driver is used (omit option -global qxl-vga.revision=4). In this case lspci
reports:
00:02.0 VGA compatible controller: Red Hat, Inc. Device 0100 (rev 03)
and dmesg reports:
[drm] Initialized drm 1.1.0 20060810
[drm:qxl_pci_probe] *ERROR* qxl too old, doesn't support
client_monitors_config, use xf86-video.
I can provide further information, but need some guidance, what you prefer in
order to locate the root cause of the problem.

Hi,
Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated
to http://gitlab.freedesktop.org.
To avoid migrating out of date bugs, I am now closing all the bugs that did not
see any activity in the past year. If the issue is still happening, please
create a new bug in the relevant project at https://gitlab.freedesktop.org/drm
(use misc by default).
Sorry about the noise!
