libvirt users - Jun 2015 - <vcpu placement='static' current='N'>M</vcpu>

Hello.

I seem to be to stupid to configure vcpu hotplugging on one of my
machines. Whenever i set:

<vcpu placement='static' current='4'>4</vcpu>

and save this setting, this setting is undone by libvirt. It jumps back to:

<vcpu placement='static'>4</vcpu>

I'm confused now. Someone has an idea what's going on here? Any hints
are really appreciated.

cheers

Aieee! It seems this setting is not needed anymore. "<vcpu
placement='static'>8</vcpu>" just works fine. I can
downscale with this
setting as i wish.

Whenever current == vcpu the attribute is just not put into the XML.
