Auto-starting Xen/xVM domains in OpenSolaris

Posted by peter on May 19, 2009

Normally, when using Red Hat’s tools (which like everyone else Sun has ripped off wholesale) this is exposed in virt-manager and virsh, but the versions that Sun has brought over from Redhat lag quite a bit behind upstream, so you have to dig in below the convenience tools. Shut down your guest, then use xm list -l to dump the xen config file. There’s a on_xend_start property in here- change it from ignore to start, then dump it back into xen with xm new -F .sxp.

All at once:

pfexec xm list -l  > guest.sxp
sed -i 's/on_xend_start ignore/on_xend_start start/' guest.sxp
pfexec xm new -F guest.sxp

..and you’ve got a domain that’ll auto-start when xend is brought up, which is pretty much what I usually want.
