Public bug reported:
Hi.
KQEMU crashes if you trying to attach new machines with libvirt-manager.
Already (auto) running machines lost the virtual hardware NIC, also the client
are loosed the net connections. I recommend to solve this issue as soon as
possible.
I have watched:
Creating the KQEMU module with the module assistant (m-a a-i...) fails. After I
have made a new link to the linux sources, the module assistant fails too.
Creating the module in /usr/src/kqemu.. running well. After the
installation.sh, a KQEMU module is running after reboot (or with insmod), but
with the errors I have described above.
The following may help you to find the errors:
Messagebox output:
Unable to complete install '<type 'exceptions.RuntimeError'> It appears that
your installation has crashed. You should be able to find more information in
the logs
