Bug Description
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.
Traceback (most recent call last):
File "/usr/share/
dom = guest.start_
File "/usr/lib/
return self._do_
File "/usr/lib/
raise RuntimeError, _("It appears that your installation has crashed. You should be able to find more information in the logs")
RuntimeError: It appears that your installation has crashed. You should be able to find more information in the logs
