 This is not acceptable, since the guests are basically tar files that are unaware of the existance of xen. They are pre-created ostemplates from jailtime.org and it is the duty of the host to provide transparent virtualization. Also just think of the scale. It is always better to get ONE host working properly rather than to makes sure that 200 guest ostemplates are all kept in sync.
