Re: [ovirt-users] Jumbo Frames
Why do you use OVS at all? If you have VLANs, all you need is to tag the
mgmt traffic, and create a VM traffic VLAN with a different MTU. The bridge
and underlying NICs will have MTU=9000 and the VM bridge will have MTU=1500

Hello:
am really enjoying oVirt but have now hit an issue with iSCSI. As there
is only one NIC in the host I have had to enable an MTU of 9000 on
ovirtmgmt. Then have vNIC profiles on that interface which are using a
custom hook for Openvswitch. I have created a specific vLAN for iSCSI
traffic and on the initiator and targets have set their respective
interface MTUs to be 9000. When I connect to a LUN it is timing out
straight away with a 1011 error. If I drop the MTU back to 1500 all works
okay. This is all fine on my other KVM, non-oVirt, system so am wondering
if I have missed a step ?
Thanks, Phil
