mtu 9000 on OVS IntPort for Proxmox management

[mad1993max]

Hi i would like to set mtu 9000 on my promxox management port, which i configured as a tap port for a ovs switch on which I enabled mtu 900.
My /etc/network/interfaces looks like this:

auto eth0
iface eth0 inet manual

auto eth1
iface eth1 inet manual

allow-vmbr0 bond0
iface bond0 inet manual
          ovs_bonds eth0 eth1
          ovs_type OVSBond
          ovs_bridge vmbr0
          ovs_options lacp=active ...
          pre-up ( ifconfig eth0 mtu 9000 && ifconfig eth1 mtu 9000)
          mtu 9000

auto vmbr0
iface vmbr0 inet manual
          ovs_type OVSBridge
          ovs_ports bond0 vport1
          mtu 9000

allow-vmbr1 vport1
iface vport1 inet static
           address 192.168.0.2
           netmask 255.255.255.0
           gateway 192.168.0.1
           ovs_type OVSIntPort
           ovs_bridge vmbr0
           ovs_options tag=1
           mtu 9000

I tried to add the pre-up line also to the vport1 but that it wouldnt come up at startup. Hase someone solved this problem or an idea on how to?

There is a known bug with bonding. I have the same problem. I hope this problem will be solved soon.

ok now it suddenly worked but the downside is it broke the web gui so i reverted back to mtu 1500 and the web ui worked again
