Paravirtualization coming to KVM?
Posted by Fraser Campbell Sat, 06 Jan 2007 04:37:00 GMT
In a post to kvm-devel this afternoon, Ingo Molner announced a patch to support paravirtualization under KVM. The support speeds up context switches and TLB flushes.
The email announcement is here, some interesting snippits:
2-task context-switch performance (in microseconds, lower is better): native: 1.11 ---------------------------------- Qemu: 61.18 KVM upstream: 53.01 KVM trunk: 6.36 KVM trunk+paravirt/cr3: 1.60
KVM will be available in the stock 2.6.20 kernel, great news and at the current pace I’d expect it to be quite a powerful solution before long.
Would be great to hear from Qumranet though …
