Dear all:
I found a bug of qemu: hot-pluging a vhost-net may cause virtual machine crash
in following steps:
1. Starting a vm without any net device.
2. Hot-pluging 70 memory devices.
3. Hot-pluging a vhost-net device.
After the 3rd step, the qemu crashed with following messages:
vhost backend memory slots limit is less than current number of present memory
slots
warning: vhost-net requested but could not be initialized
qemu-system-x86_64: ../net/net.c:1106: net_client_init1: Assertion `nc' failed.
