Subject: KVM vs Xen/OpenVZ for VPS hosting business
Hello,
Currently both Xen and OpenVZ are well known and
KVM would like to provide x2APIC interface to a guest without emulating
interrupt remapping device. The reason KVM prefers guest to use x2APIC
is that x2APIC interface is better virtualizable and provides better
performance than mmio xAPIC interface:
- msr exits are faster than mmio (no page
