We have a VPS with a US provider that uses Xen and allows us to install our own kernel. We can either select Xen HVM mode and use a standard kernel (reduced performance) or Xen PV mode (high performance) and use a Xen kernel (the 2.6.38 mainline kernel works as a guest with Xen config as well with no extra patches). According to /sys/hypervisor/version/ our US VPS server is running on Xen 3.4.3 which is more recent than the current Crucial Xen version: 3.1.2-194.26.1.el5 . Would it be possible to implement this on the current host servers?
