Slightly off topic for this thread, but something which hasn't quite 
sunk in for me yet. You are running a Dom0 with the 3.4.0 hypervisor and 
the Lenny 2.6.26-2 xen kernel. The lenny xen kernel is (IIRC) patched 
with the 3.2 version of Xen.
So my question is, what is the difference on the kernel side between the 
different versions of xen? Is there any advantage of having the kernel 
patched with Xen 3.4 over 3.2?
Also, the new features in each Xen release, do these only require the 
updated hypervisor? Does it matter which kernel is running in Dom0 as 
long as it supports Xen?
Thanks,
Jeff
