[Xen-users] Hi - Regarding xend - xm create Error

[Mahendra Kutare <mahendra.kutare@xxxxxxxxx>]

Hi,

I am able to get Xend running on Fedora 8 but when I try to create any
VM it fails.

The xm create osc.cfg throws following error -
[root@asds174 vm_images]# xm create osc.cfg

The /var/log/xen/xend.log shows the following -

Anyone can provide some pointers on this ?
