Re: [Xen-devel] xen4.5 dom0pvh test failed

["Yuzhou (C)" <vitas.yuzhou@xxxxxxxxxx>]

Hi Roger,

        I did the tests with three ways:

(1). xen4.5+linux3.17.4+dom0pvh=1, boot failed!
        please view the attachment (xen4.5+linux3.17.4+dom0pvh=1.boot.log).  

(2). xen4.5+linux3.17.4+dom0pvh=1+dom0_mem=4096000, boot failed, but different 
from (1).
        please view the attachment 
(xen4.5+linux3.17.4+dom0pvh=1+dom0_mem=4096000.boot.log).  

(3). Xen4.5+linux3.17.4, boot OK.
        If needed, please view the attachment (xen4.5+linux3.17.4.boot.log).

For Linux kernel config, please view the attachment (config-3.17.4-4-xen).

        Thank you for your help!

Thanks,

Yuzhou
