Re: [Xen-ia64-devel] RE: Has anyone seen this before? vcpus > 1 panics DomU kernel

[Alex Williamson <alex.williamson@xxxxxx>]

   Very odd, I run 4-way HVM guests all the time.  The domain boots if
vcpus=1 is set in the config file?  You might try removing the quiet
option from the guest elilo to see if you get any informative boot
messages.
