Hi Javier,

It doesn't work for me:

server:/tmp# cat a
vif = [ 'ip=167,112,134.223,mac=00:16:3E:FD:58:B8']

server:/tmp# sed -i
'/^vif/s/B8.*$/C8,vifname=veth216'"'"','"'"'ip=10.1.1.1,mac=00:16:3E:FD:58:BB,vifname=veth216a'"'"']'
a
sed: -e expression #1, char 87: unterminated `s' command


regards,
Israel.
