I am running the 2.6.30 dom0 kernel (suse patched) and everyting else is working except suspend:

When I try to run "xm save" the domU will shutdown and in xend.log I can see following:

2009-07-16 18:09:34 2559] DEBUG (XendCheckpoint:110) [xc_save]: /usr/lib64/xen/bin/xc_save 57 6 0 0 0 [2009-07-16 18:09:34 2559] INFO (XendCheckpoint:417) ERROR Internal error: Can't create lock file for suspend event channel

And then I just have to restart the domU. The only kernel that I have tested with working suspend is the defaul pv_ops, suse patched and the novell 2.6.27 all fail the same way.

What could be the problem?
