Thanks Erik,
actually i want to increase MTU of instance from
1500 to 8000,from what i know "dhcp-option-force=" will only change
MTU of vNIC and not all the interfaces related to neutron.Can this be
also changed.

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
If you are using neutron you need to change it there
ovs_neutron_plugin.ini agent veth_mtu 1500 for example.

The DHCP option will only change the MTU of interfaces within the
instances. You probably don't want to lower the bridge ibtefaces sine the
point of lowering instance MTU is to account for GRE / VXLAN overhead going
into those bridge interfaces. If you lower everything, you'll still be left
with po
Yo need to change nova.conf this settings are for your vm which get the ip
address from dhcp

Hello all is there any way we can change MTU of all relevant
interfaces of instances,if i set
dhcp-option-force=26,1400 will it change MTU of all relevant
interfaces like qbr qvo br-int etc etc
is there any way to change MTU of all neutron interfaces.
Thanks
