OpenVZ dnsmasq set capabilities failed fix

When running dnsmasq under OpenVZ I sometimes get an error when restarting: set capabilities failed. This is because dnsmasq starts as root, then does privileged stuff and then drops to the configured run user. In OpenVZ these permissions are not passed to the VPS, sadly. These three commands fix the problem.

Replace 195 with your container ID in the steps below.
Stop the container:
vzctl stop 195
Give it extra permissions:
vzctl set 195 --capability setuid:on --save vzctl set 195 --capability net_admin:on --save vzctl set 195 --capability net_raw:on --save
Then start it again:
