Hello all

I am trying to launch:

kernel = "/boot/vmlinuz-2.6.12-xenU"
memory = 512
name = "oes1"
disk = [ 'phy:vgdata/lv_xen_oes1,md0,w' ]
dhcp="dhcp"
root = "/dev/md3 ro"
extra = "4"

End result is:
bicolor:~/hg-xen-unstable/xen-unstable.hg # xm list
Name              ID  Mem(MiB)  CPU  VCPUs  State   Time(s)
Domain-0           0       251    0      1  r-----    553.2
Zombie-oes1        1         0    1      1  ----cd      0.4
oes1              54       503    1      1  r-----      1.9

I get:

bicolor:/etc/xen # xm create oes1 -c
Using config file "oes1".

While I can shutdown 'oes1', I cannot make Zombie-oes1 go away, even
with xm destroy. A reboot makes it go away.

As you can see above, raid modules are loaded. What am I missing?
which device is unknown-block(2,0) ?

Thanks for the help.
