[Qemu-devel] [PATCH 3/3] hyperv: make SynIC version msr constant

The value of HV_X64_MSR_SVERSION is initialized once at vcpu init, and is reset to zero on vcpu reset, which is wrong. It is supposed to be a constant, so drop the field from X86CPU, set the msr with the constant value, and don't bother getting it. Signed-off-by: Roman Kagan

[Qemu-devel] [PATCH 1/3] hyperv: set partition-wide MSRs only on first vcpu

From: Evgeny Yakovlev Hyper-V has a notion of partition-wide MSRs. Those MSRs are read and written as usual on each VCPU, however the hypervisor maintains a single global value for all VCPUs. Thus writing such an MSR from any single VCPU affects the global value that

[Qemu-devel] [PATCH] kvm: apic: save and restore x2APIC LDR

QEMU saves only 8 bits of APIC LDR, which means that it does not support x2APIC. The correct way of fixing this would be to save and restore the full 32 bit register, but because x2APIC LDR is a function of x2APIC ID, we can also compute it and keep the migration format untouched. KVM always
