[Qemu-devel] qemu-kvm-1.0 crashes with threaded vnc server?

[Peter Lieven]

Hi,

is anyone aware if there are still problems when enabling the threaded 
vnc server?
I saw some VMs crashing when using a qemu-kvm build with 
--enable-vnc-thread.

qemu-kvm-1.0[22646]: segfault at 0 ip 00007fec1ca7ea0b sp 
00007fec19d056d0 error 6 in libz.so.1.2.3.3[7fec1ca75000+16000]
qemu-kvm-1.0[26056]: segfault at 7f06d8d6e010 ip 00007f06e0a30d71 sp 
00007f06df035748 error 6 in libc-2.11.1.so[7f06e09aa000+17a000]

I had no time to debug further. It seems to happen shortly after 
migrating, but thats uncertain. At least the segfault in libz seems to
give a hint to VNC since I cannot image of any other part of qemu-kvm 
using libz except for VNC server.

Thanks,
Peter
