Hi Chris,
I think vzctl create command invokes processes which occupy CPU and
Disk I/O.
It seems clearly necessary for such commands to prevent from running
prior to other processes.
But I almost agree with you. We should have flexibility about it for
users.
As you said if it requires to encode policy into libvirt, we should
avoid it still now.
And I want to spend more time in writing some other patches :)

Hi all
About OpenVZ, it uses vzctl command that produces tar/gzip commands.
I think we should lower these commands for running other procedures
prior to them.
This is the patch to achieve it with nice/ionice commands.
I'm not sure that this is such a good idea, as it is encoding policy
into
libvirt. There have been other requests for being able to set the
priorities of
certain domains, so it might make sense to have a more generic
"priority"
concept that could be set by the user. Then the user would specify
how
important a particular task is, and we wouldn't be putting any
policy into
libvirt itself.
