Description Ladislav Slezák 2008-06-19 06:40:28 UTC

When I doubleclick on 'localhost - xen' line in virt-manager after start it crashes immediately.

Starting it from command line shows that it crashes due to a floating point exception:

# virt-manager --no-fork -c xen://
Floating point exception

Comment 1 Matthias Brenner 2008-06-23 18:09:08 UTC

I encountered the same problem:
double opteron system, OpenSuse 11.0, 64bit
I tried with pdb to localize the problem in /usr/share/virt-manager/virt-manager.py

it fails in /usr/lib64/python2.5/site-packages/libvirt.py
772  ->     def getInfo(self):
773             """Extract hardware informations about the Node. """
774             ret = libvirtmod.virNodeGetInfo(self._o)
775             if ret is None: raise libvirtError ('virNodeGetInfo() failed', conn=self)
776             return ret
777
(Pdb) s
> /usr/lib64/python2.5/site-packages/libvirt.py(774)getInfo()
-> ret = libvirtmod.virNodeGetInfo(self._o)
(Pdb) s
Floating point exception

At this point I know to less about python to go ahead. 
Line number will not match the product, due to import pdb and trace statement.

I will be trying to reproduce this.

In the mean time, could you attach your /root/virt-manager/virt-manager.log file?

Thanks

Created attachment 224472 [details]
virt-manager.log

The log is similar to the previous one.

This is the same issue we're seeing in #398932

We'll finish looking at it Friday, when Jim gets back.
