Re: [Xen-users] unable to get domain type for domid

[soapcn <soapcn@xxxxxxxxx>]

I'm using 12.04 actually. Here are the commands I used:

update-rc.d xencommons defaults 19 18
update-rc.d xendomains defaults 21 20
update-rc.d xen-watchdog defaults 22 23

For some reason I don't have xen-init-dom0 after building from source.

Your dom0 is trusty 14.04?

The `unable to get domain type for domid` error should be caused by a missing service at xen startup.

Its called

xen-init-dom0

Take a look at

`ls -al /etc/init.d | grep xen`

be sure to enable xen-init-dom0.

Hi,

I keep getting this error about not being able to get domain type when I try to create a domU.
