Subject: vhost user examples


Hi Xie,

I would be interested in alpha testing the vhost user patchset.

Is there an up to date example of how to use it ?

vHost has a parameter called base_name. Temporarily you could specify --base-name as
the unix domain socket path, and set it in the qemu command line as socket path.
recommended qemu command line for memory and vhost configuration:
-m $MEM -object memory-backend-file,id=mem,size=${MEM}M,mem-path=/mnt/huge,share=on -numa node,memdev=mem  -mem-prealloc
-chardev socket,id=char0,path=$sock_path  -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,mac=52:54:00:12:34:11,netdev=mynet1

Thanks,

Is the upstream vhost example in master already patched for this ?
Or does it still required some patches ?

Best regards
