Steps to Reproduce:
1.boot guest with spice + qxl
e.g:/usr/libexec/qemu-kvm -M q35 -cpu SandyBridge -enable-kvm -m 4096 -smp 4,sockets=2,cores=2,threads=1 -no-kvm-pit-reinjection -name sluo -uuid 355a2475-4e03-4cdd-bf7b-5d6a59edaa61 -rtc base=localtime,clock=host,driftfix=slew -device pci-bridge,bus=pcie.0,id=bridge1,chassis_nr=1,addr=0x3 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,vectors=0,bus=bridge1,addr=0x4 -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait -device virtserialport,chardev=channel1,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port1 -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2 -drive file=/home/RHEL-7.0-20130628.0-Server-x86_64.qcow3,if=none,id=drive-system-disk,format=qcow2,cache=none,aio=native,werror=stop,rerror=stop,serial="QEMU-DISK1" -device virtio-scsi-pci,num_queues=4,id=scsi0,bus=bridge1,addr=0x5 -device scsi-hd,bus=scsi0.0,drive=drive-system-disk,id=system-disk,bootindex=1 -device virtio-balloon-pci,id=ballooning,bus=bridge1,addr=0x6 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -netdev tap,id=hostnet0,vhost=on,queues=4,script=/etc/qemu-ifup -device virtio-net-pci,mq=on,vectors=17,netdev=hostnet0,id=virtio-net-pci0,mac=08:2e:5f:0a:0d:b1,bus=bridge1,addr=0x7,bootindex=2 -k en-us -boot menu=on -qmp tcp:0:4444,server,nowait -serial unix:/tmp/ttyS0,server,nowait -spice port=5931,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -monitor stdio

Actual results:
after step 1, guest will call trace, i will attach the log later.

Expected results:
it should have no any call trace with spice + qxl.

Also seeing this on Fedora 19 guests.

Seems like a linux (kernel) qxl driver issue, moving to xorg-x11-drv-qxl
Comment 5 Søren Sandmann Pedersen 2014-01-10 14:27:07 EST
Does this happen with recent RHEL 7 kernels?

Tried the recent rhel7 kernel with the same testing as comment #0 which did not meet such issue any more.

host info:
# uname -r && rpm -q qemu-kvm
guest info:
# uname -r
