Re: [Xen-users] QXL problem: Xen 4.4.1 rc1 and xen 4.5 unstable

[Fantu <fantonifabio@xxxxxxxxxx>]

Thanks for testing spice and qxl and report issue.
I have spice + qxl working as kvm on xen unstable except this problem:
http://lists.xen.org/archives/html/xen-devel/2014-07/msg01021.html

Please post details on your dom0 installation and domU (for example xl cfg,
spice guest tools version ecc...)
About qemu crash try to take a full backtrace with gdb and post it here.

Small help with gdb of qemu launched by xl:

Add the line below in domU's xl cfg:
device_model_override="/usr/lib/xen/bin/qemu-gdb"

vi /usr/lib/xen/bin/qemu-gdb # create the file, change the qemu path if
needed
#!/bin/sh
exec gdbserver 0.0.0.0:1234 /usr/lib/xen/bin/qemu-system-i386 "$@"

# after xl create, do it fast (before timeout or xl create will fails)
target remote localhost:1234
c 
bt full # when qemu stops

You should install also all needed dbg packages before, spice qemu ecc or
without package should be compiled with debug enabled (for xen and qemu
default in unstable).

The latest qemu crash with spice I saw was in 2.0-rc solved before 2.0.0
final, your qemu is at least 2.0.0 final?
