[Xen-users] xen-create-image:ALERT! /dev/xvda2 does not exist. Dropping to a shell
hi,
i install xen-4.2 on debian6.0(i386)/squeeze,and the dom0 kernel is 2.6.32.40.
i create a domU successfully using xen-create-image:xen-create-image --hostname
localhost --ip 192.168.226.242 --verbose

but when i start this domU(xm create -c /etc/xen/localhost.cfg),error happens:

- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)

yeal,you are right~
1)root@debian:/bootapt-get install linux-image-2.6-xen-686(for i386)
2)root@debian:/boot# ls /boot/
config-2.6.32.40 initrd.img-2.6.32-5-xen-686 vmlinuz-2.6.32-5-686-bigmem

initrd.img-2.6.32-5-686-bigmem vmlinuz-2.6.32.40.old xen-syms-4.2-unstable
3)vim /etc/xen/localhost.cfg:

on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''
4) i can start the domU successfully.that''s ok,thank you very very very
