Thanks Remo, this is exactly what i am looking for with this changed to 8000 and dhcp-option-force=26,8000 will all interface created for that instance get this MTU or just veth pairs.I mean will it change MTU of bridge created for each instance ie qbr-portid , its veth pairs qvb-portid ,qv0-portid then patch ports between br-tun and br-int.My switch supports upto 9000 and i can change eth0 MTU 8000+ (ip header+GRE+VLAN). I was thinking for writing a script to change MTU of all interfaces connected to vms,your information was very helpful
