Bug 734358

Description of problem:
Install a RHEL6.2 guest with the RHEL6.2-20110823.1/ tree with spice. After finish installation, can not resize client resolution to larger value, and the largest resolution is 1024x768. Another issue is on the guest login screen, the mouse will be captured by the guest. After login to guest desktop, it can move out from guest.
So check the guest related packages version, they are:
kernel-2.6.32-191.el6.x86_64
xorg-x11-drv-qxl-0.0.14-5.el6

Then I upgrade xorg-x11-drv-qxl to 0.0.14-6 and reboot guest,but guest will hang on the login screen. If system_reset it in the qemu monitor there's prompt: (qemu) system_reset 
(qemu) red_wait_outgoing_item: blocked

Guest still hang after system reset, the qemu-kvm process consumes 100% host cpu. 

Version-Release number of selected component (if applicable):
Host:
kernel-2.6.32-192.el6.x86_64
qemu-kvm-0.12.1.2-2.184.el6.x86_64
Guest:
install tree: RHEL6.2-20110823.1
kernel-2.6.32-191.el6.x86_64
xorg-x11-drv-qxl-0.0.14-5.el6.x86_64


How reproducible:
Always

Steps to Reproduce:
1.Install and boot a RHEL6.2-64 guest with spice
/usr/libexec/qemu-kvm -M rhel6.2.0 -cpu cpu64-rhel6,+x2apic  -enable-kvm -m 4096 -smp 2,sockets=2,cores=1,threads=1 -name RHEL6.2-64 -uuid 2b379603-6f73-497c-bbdc-d3dc948248e8 -monitor stdio -rtc base=localtime -boot c -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x4 -drive file=/home/RHEL6.2-64.qcow2,if=none,id=ide-drive-0,format=qcow2,cache=none,werror=stop,rerror=stop -device ide-drive,bus=ide.0,unit=0,drive=ide-drive-0,id=ide0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,id=net0,mac=00:1a:4a:10:84:09,bus=pci.0,addr=0x3 -chardev socket,id=charchannel0,path=/tmp/foo,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -usb -spice port=5930,disable-ticketing -k en-us -vga qxl -global qxl-vga.vram_size=67108864 -device virtio-balloon-pci,bus=pci.0,id=balloon0

2.Check the guest kernel, xorg-x11-drv-qxl version.
3.Check if the virtio serial and spice-vdagent work well.
Copy/paste some strings from guest to external host. It works.

3.Resize guest screen resolution by click "System" -> "Preferences" -> "Display" on guest desktop.
  
Actual results:
Can not set resolution to larger than 1024x768.
Guest's mouse is captured on the login screen.

Expected results:
Should have more resolution values larger than 1024x768 that's supported by spice+qxl.
Guest's mouse should move external host and guest freely before and after login.

Additional info:
I reinstall a RHEL6.1-64-released guest on the same host, can change the guest resolution successfully.
But after I upgrade RHEL6.1 guest's kernel to a RHEL6.2 version. Sometimes the guest mouse will be captured by desktop.
