[Qemu-devel] [PATCH] vhost: make priority higher than kvm

[Liu Ping Fan]

From: Liu Ping Fan <address@hidden>

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.
