I was wondering, if I do not have hardware that natively supports full virtualization...and I choose to use KVM, will my VMs be running in some form of chip emulation (and therefore terribly slow). To date, I've been using Xen and am very comfortable with it. I have some fears that later whenever Xen is dropped - I'll have to consider KVM. Also, will Xen be carried forward should Xen be dropped from RHEL? -- Scot P.

However it might (actually I am pretty sure this will happen) no longer get enhancements after a given time (but only bugfixes)

RHEL5 will be supported until 2014. So Xen will be supported in RHEL5 until 2014. Redhat has stated this many times.> Also, will Xen be carried forward should Xen be dropped from RHEL? >RHEL6 will run as Xen guest/domU, even if RHEL6 won't have Xen dom0 support. Upstream Xen development is very active, so no worries there either. -- Pasi> > -- > Scot P.
