Description Julian Stecklina 2013-07-12 11:13:03 UTC 
/dev/vhost-net, which is necessary for decent network performance in qemu/kvm, is only accessible by root. By default it is owned by root and gets 0600 rights.

I would expect /dev/vhost-net to be owned by group kvm or qemu and group-read/writable.

Adding a udev rule such as
SUBSYSTEM=="misc", KERNEL=="vhost-net", GROUP="kvm", MODE="0660"
does not work for me.
Comment 1 Cole Robinson 2013-09-09 13:39:28 UTC 
Michael, is this safe to do? /dev/kvm is already non-root
Comment 2 Michael S. Tsirkin 2013-09-10 15:12:58 UTC 
I think root-only is a better default. What exactly happens when you add the udev rule?
Comment 3 Cole Robinson 2013-10-31 21:08:22 UTC 
No response, closing as INSUFFICIENT_DATA (and sounds like enabling for non-root isn't recommended anyways)
