Re: [libvirt-users] vhost-net requested but could not be initialized

For qemu, the default vhost drive file is “/dev/vhost-net”, when you configured vhost on. Give the command “modprobe vhost-net” to add host kernel support for vhost. This is cannot controlled by libvirt I think.

The qemu doesn't use the default "/dev/vhost-net" directory as character device. Due to this I am getting the error: qemu-system-x86_64: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net requested but could not be initialized ​Is there a way to tell libvirt to ​avoid using the default /dev/vhost-net file? I have tried using the pass-through arguments but libvirt still processes the command and throws the error. PS: I can successfully create a vhost VM using qemu command-line, so this is a libvirt issue. -- Cheers, Asadullah Hussain
