[Xen-users] Kernel Errors: SLES 11 - XEN-3.3.1

[James MacLean <macleajb@xxxxxxxxxxx>]

Hi Folks,

First time I've seen these errors. This is a slice of Windows 2003 with 
James' PV drivers installed.
When it says "a reboot is needed" does it mean the slice or the Dom0 ?

Hope this doesn't mean I can not use the 10G card that it seems to be 
referring to  :(.
