Hello there, forwarding messages regarding remote-viewer/spice-QXL bugs.
I'm using Deb8 unstable (sid) -software list attached- with Xen 4.5RC4
with Qemu upstream, seabios from Deb8 unstable, QXL patch from Fantu and
remote-viewer.
Trying to run a Win7 x64 vm which runs fine using vnc but having issues
with spice:
on reboot I loose ability to access the machine
if I resize/move window, randomly -or sort of- it can close remote-viewer
window saying that it can't connect.
Here are two gdb / trace full of Xen.
Does someone have an idea cause I'm short here.
can provide any log needed.
regards
greg B

another bt full,
same problem with remote-viewer, this time trying to move the window and it
sticked somewhere -you know those sticky functions that develop a window-
so that it fits one half or smtg...
