[Xen-devel] Suspend/save wont work with the newer dom0 kernels

[Valtteri Kiviniemi <valtteri.kiviniemi@xxxxxxxxxxxx>]

Hi,

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

XendDomainInfo.handleShutdownWatch
[2009-07-16 18:09:34 2559] DEBUG (XendDomainInfo:1709) 
XendDomainInfo.handleShutdownWatch
And then I just have to restart the domU. The only kernel that I have 
tested with working suspend is the defaul 2.6.18.8. pv_ops, suse patched 
and the novell 2.6.27 all fail the same way.
What could be the problem?
