Hi all,
 
Firstly please forgive me if I put this problem in the wrong mail list. 
However, it seems that xen-users mail list cannot resolve this QXL 
problems. Therefore, I have to post QXL problem in devel mail list.
My problem is as follow:
 
I'm testing QXL for windows HVM, spice works well with stdvga. 
However, when I switch to QXL, qemu exit abnormally:
I specify vga="qxl" and videoram=128, using qemu-xen. The windows 7 boots 
and automatially switch resolution for me in virt-viewer.
While display and sound transfering very well, if I change display 
resolution, the virt-viewer will be suddenly closed and
I check the physical server, the qemu process disappear simultaneously. 
Then I switch to wheezy backport qemu 2.0 as device model, the qemu process 
will exit as soon as the welcome page appears and at the beginning of resolution 
change.
I tested and found the same bug on both xenbits xen 4.4.1 rc1 and Fantu's 
Xen 4.5 unstable, this problem exists in both branches.
Is it a known issue or is there any solution for this bug?
Thank you very much!
