Install a dom-u problem.

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'', ]
: on_reboot = ''destroy''
: on_crash = ''destroy''
: #bootloader="/usr/bin/pygrub"
: extra = "text"

but hang on this screen...
http://imageshack.us/photo/my-images/201/6v1j.gif/

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:

You don''t say which distro this is but it seems like the problem is
with
their installer, your disk configuration looks correct to me. I
recommend you ask on the appropriate distro list.

You could also check wiki.xenproject.org, there are HOWTOs for many
distros and you may find a guide for yours which helps avoid whatever
the problem is.

Finally, I appeared the disk problem because I mkfs at Dom-0 already,
so Dom-U can''t use them,but in text mode won''t show detail
message.
I try several days, then know I did wrong at this in VNC install screen.

VmError: Boot loader didn''t return any data!>
I think maybe I didn''t set ks.cfg correctly or disk problem above,
so /usr/bin/pygrup couldn''t work..

So I must learn how to save Dom-U domain info after I install it now,
or after I install and reboot(destory) it, I don''t know how to find it
back...

I find my wrong early,
After I install a domu, I should comment kernel and ramdisk both,
then just set the bootloader to pygrup,

I didn''t how set it before.
