What kernel are you using for your guest? The event channel warning
suggests it's not 2.6.18. If you can, use the Xen 2.6.18 kernel for
your guest as well. Also, take a look at the instructions here:

I have no idea where that kernel comes from or how old it is. It may
be missing event-channel suspend support. Try building the 2.6.18 tree
hosted at xenbits: http://xenbits.xen.org/linux-2.6.18-xen.hg

2.6.18-128.e15xen is Redhat RHEL 5.3 default kernel..

It doesn't have the latest Xen bits.. when was that added to linux-2.6.18-xen.hg ?
