Hi,
I updated my libvirt git clone and install yesterday (after about a
month or so) and now I can't start domains:
$ virsh start fedora18
error: Failed to start domain fedora18
error: unsupported configuration: This QEMU does not support QXL
graphics adapters
While libvirt is self-built, I'm using qemu 1.2.2-1.fc18 from vanila
Fedora 18 repo. Just to be clear, qemu was not updated before the
problem appeared, only libvirt.
Here is the libvirtd log:
http://static.fi/~zeenix/tmp/libvirtd-session-zeenix.log (13 MB).
Also attaching the domain config.
If my `git bisect run` script worked, I've found the commit
introducing this issue:
4c993d8ab5473334e9d4155faa913476ada39069 is the first bad commit

Fix a typo in qemuCapsObjectTypes, the string 'qxl' here
should be -device qxl rather than -vga [...|qxl|..]

Basically for some reason we tried to build the command line up as
qemu-kvm ... -vga qxl instead of -device qxl-vga which is what I
thought Guannan was aiming for. I could be wrong though. I'll take
another look at it tonight.
When libvirt reports this error, probably the qemu you are
using doesn't support
qxl-vga as the primary video device, and at the same time the
qemu doesn't
support "-vga qxl" either.
The reason why libvirt worked out before is that there is a
typo for the caps flag bit
QEMU_CAPS_VGA_QXL fixed in the above commit. And libvirt didn't set
QEMU_CAPS_VGA_QXL on for qemu(>1.2) by using QMP mode to check
for qemu
capabilities.
- { "qxl", QEMU_CAPS_VGA_QXL },
+ { "qxl", QEMU_CAPS_DEVICE_QXL },
So Doug's patch probably could fix your problem temporarily,
but we need to think it
through as Eric said.
