RE: Problem with auto-starting DomU on NetBSD5.0.2 running Xen3.3
Other question I had (and never asked so far) was if we have multiple guest
domainname put in xendomains param in rc.conf, I assume the order of creating
them is as specified in the param. Does it also guarantee that a given VM is up
and running before next VM is going to be created. I know that the definition
of "up and running" is subject to user interpretation. What I want to find out
is if there's any way to serialize the VM creation and have hook which checks
(using xm commands) if the given VM has reached a particular state before going
to next VM.
I could think of two ways to do that. Pl let me know which one I should go with
or if you have any better alternative.
1) Put hooks in xendomains script itself to check if given VM is active. Put
sleep to wait if required.
2) Get rid off the auto-creation of VM. That is, xendomains in rc.conf is
empty. Have a custom script to be called during init (after xend/xenbackend of
course) that creates the domains (using xm create) serially and makes sure one
is up before next is created.

Looks like auto_ifconfig was set to NO in rc.conf, due to which the interfaces
were not created in /etc/rc.d/network script. Hence, xendomains complained
about not able to connect the vif to bridge. I still don't know how the bridge
got created later on.
Once, I set auto_ifconfig to YES, the bridge was created and xen had no problem
creating the guest domain.
Thanks Manuel for helping me narrow down the issue.

looks good, xen is started near the end.
Next thing would be to boot single user and check that
does indeed create the bridge.
