I got trouble with install Dom0 in XEN 4.3.1 PV mode,

how should I mount the file system to dom0 correctly?

I mkfs two sub-volgooup partitions for domU on a mdraid(1) LVM disk,

but didn't let dom0 mount.

# lvs

LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert

xen-dom_0 vg -wi-a---- 5.00g

xen-swap vg -wi-a---- 1.00g

# ls /dev/mapper/

control vg-LogVol0 vg-LogVol1 vg-LogVol2 vg-LogVol3 vg-xen--dom_0 vg-xen--swap

I use a test.cfg file:

xm create test -c

: kernel = "/boot/vmlinuz-xen4-install"

: ramdisk = "/boot/initrd-xen4-install"

: name = "test"

: vcpus=2

: memory = "1024"

: disk = [ 'phy:/dev/mapper/vg-xen--dom_0,xvda,w', 'phy:/dev/mapper/vg-xen--swap,xvdb,w', ]

: vif = [ 'bridge=br0', ]

: >

: #bootloader="/usr/bin/pygrub"

: extra = "text"

but hang on this screen...

I can't go to next page whatever I choice what option here,
and once I enter at that green place,It's hang.

how should I do or read what docu to make a correct disk path?

(and PV mode can't mount two or more disk with xvd* ?)

and,if I uncomment

: bootloader="/usr/bin/pygrub"

got another error. I check the xend log, error message is:
