This series of patches introduces checkpoint and restore operations for the VMX state of a VM, so that VMX-capable VMs can be migrated. Two new ioctls are introduced: KVM_GET_VMX_STATE and KVM_SET_VMX_STATE. The VMX state that is checkpointed/restored consists of the VMXON region address (if any), the current VMCS address (if any), and the cached current VMCS contents (if any). One piece of implementation-specific state that is also checkpointed/restored is the nested_run_pending bit. On live migration, our userspace process does not have access to guest memory when the VM is set up on the target host, so some operations that require a GPA->HPA mapping are deferred until the next vcpu_run using a new vcpu request. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
