I've done some more searching on this (remember those people that say
you don't need to know, you just need to look up? I wonder if they
imagined hours of googling instead of *knowing*)

So I checked for "xm trigger" on my dom0 and it had the command (Xen 4.0.1)
It has the following options and is not documented in the xm manpage.
"waxh0002:~# xm trigger
Usage: xm trigger <Domain> <nmi|reset|init|s3resume|power> [<VCPU>]
Send a trigger to a domain."
Using xm trigger xen08 power the FreeBSD domU immediately started
shutdown (at usual FreeBSD speed, so it was gone roughly 1-2 seconds
I'll try to find out why it's not hooked into xm shutdown per Default
and I very strongly assume it's the typical Xen problem of the last 3
years: Actually enabling the features is an exercise left for the
I would be interested if anyone could test this on Xen 4.1.
- it might be already working there
- it might be working when using "xl" isntead of "xm"
- it might have been forgotten in "xl" and not work in "xm"
Thanks for your help so far!
the purpose of libvirt is to provide an abstraction layer hiding all
xen features added since 2006 until they were finally understood and
copied by the kvm devs.
