RE: [Xen-ia64-devel] DomU does not start.

["yo.fujita" <yo.fujita@xxxxxxxxxxxxxxxx>]

Hi Dan, Kevin,

Thank you. I succeeded in Boot of DomU by the patch of kevin. (8474)
I will start the benchmark on DomU.

However, VTI did not stand up.
Is this because virtual memmap was disable?
Please look at an attached VTI bootlog.

Thanks,
Fujita
