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. 2022-12-05 03:14:08.794+0000: shutting down, reason=crashed This commit is used to fix the mentioned problem. It is based on commit a33c25399f9bc3dcf83064adeba2a82e61bf4608 of master branch. Kind regards.
