Can you reproduce using 'virt-manager --debug' and post the output? Does restarting the app help? Does 'virt-viewer $vmname' have the same issue?

Hmm, getting worse.

I'll probably report a separate BZ for the above SIGSEGV. I'll give you the information needed when I am in the office to access the system tomorrow.

virt-manager --debug output

Hmm, if it's also an issue with virt-viewer, then this is likely either gtk-vnc or kvm. Reassigning to KVM for future triage

Works for me with sdl/vncviewer/gvncviewer (but I obviously use other PXE server). Please try other vnc clients _before_ reassigning to qemu-kvm. Reassigning back to virt-manager as the only other option for me is to close the bug as WORKSFORME.

gpxe-roms-qemu-0.9.7-6.3.el6 works fine.
