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

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

Hi, Fujita,
        I'm not sure about your target memory layout. But generally if you plug 
a >=2G memory bank in your box, you may need the patch I sent out yesterday to 
disable virtual memmap in guest. Or else vbd driver doesn't work. If you only 
have 1G-like system, then that's possibly a different issue.

Thanks,
Kevin
