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

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

Hi Roger,

        I do the test with Linux kernel 3.18.3:

(1). Base on xen4.5, linux3.18.3, dom0pvh=1, dom0_mem=4096000 ;  boot failed!
   From boot log, I think the disk device can not be scaned.
   More details , please see the attachment 
xen4.5+linux3.18.3+dom0pvh=1+dom0_mem=4096000.boot.log

(2). Base on linux 3.18.3, not xen, system boot OK.

        Thank you for your help!
