I have been using it for a year. Xen is para-virtualization, VMware is
full virtualization. Xen will be faster but requires modified guest OS
unless you have a new Intel/AMD cpu which supports virtualization in
which case it will run any x86 OS. Xen rocks. I am moving my entire
company to Xen. CPU's are vastly underutilized running just one OS
instance per box. We expect to be able to reduce our overall machine
count over the next year (saving power and datacenter space) while
continuing to grow the business. And Xen's ability to migrate running
virtual machines from one physical box to another with no downtime
(requires a SAN such as AoE, iSCSI, fibrechannel) it should greatly
increase our availability as well. If you are dual-booting between Linux
and Windows Xen won't do it for you unless you have a new cpu that
supports the virtualization extensions. You will also have to choose
which OS you want to have the graphical console (the other you will have
to access through vnc or some similar hack) because they haven't
virtualized it yet but that is coming.
Can you give some clues about "new enough" CPUs? Thanks.
