From: Liu Ping Fan <pingf...@linux.vnet.ibm.com> vhost should have high priority than kvm. Take the following scenario: kvm_region_add earlier before vhost_region_add, then vring's desc[i] can refer addressX known by guest, and then used by guest. But vhost does not know this yet, and the vring handler will fail.
