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
