From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this interrupt automatically, without any software invo...

I've been using virt-manager and kvm with a disk image (as in the raw bits) from a physical windows 7 machine. Initial performance was dreadful, but improved as I switched to virtio and spice. I've been running linux VM's somewhat longer (much longer if you count kvm without libvirt). There are lots of choices exposed by virt-manager. How do I find out what the choices mean, and

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

A minimal implementation of the Viridian (Hyper-V) guest interface. The only enlightenments advertised and supported are vAPIC MSRs and long-spin-wait notifications. The set of enlightenments can easily be extended in future, as they are found to provide a performance win, and configured via an extended HVM_PARAM_VIRIDIAN hvm parameter.
