let me tell you, what i mean. On Februar i had a  course on Vmware ESX
and i was very impressed how smooth let the system move the VMs via
VMotion to systems with a low load to balance the power on the network.
You have several options to choose, when Vmware let switch the hosts.
Vmware assign stars, from one, to five. If one VM hast nothing to to, it
has only one star, but if the load is higher and you get 3-5 stars, than
Vmware decide to move the VM to a better Host.
You have the choice, if Vmware does the VMotion automatically, or let
the admin do this.

My hope was, that Xen can this too, but it seems, that i have to do a
lot, to get this feature under Xen.

My testing system reside on a software ISCSI so all VMS can migrate all
ready without any problems :-)

The next step would be to monitoring Xen and the hosts. Most software i
saw are not enough professional enough or need a specialist for
something like nagios. But, Xen is young so, i have to be patient ;-)
