You can change the MTU in the network config in oVirt engine. The management portal. Go to clusters then networks or something like that. You can then modify the MTU.
MTU can also be set manually in network scripts on the host but you need to define this in the engine. At least this is how I got Infiniband working. I can send screenshots on Monday.

Install OS, Install OFED, Create Bond for ib0 and ib1 - bond0 Set IP to bond0, and MTU to 65520. Add Host to oVirt Cluster At this moment of time everything is Fine. Next step. Assign New network to bond0, oVirt set MTU to 1500, and ... That is all. No storage, No IP. I can't change MTU to 2044 or 65520 and can't assign IP to IB interface. From system perspective i do understand why. oVirt Creates new bridge using brctl - and brctl didn't support IPoIB, but how can i change it back to original config? _______________________________________________ Users mailing list -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]> Privacy Statement: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ovirt.org_site_privacy-2Dpolicy_&d=DwIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=2Fzhh_78OGspKQpl_e-CbhH6xUjnRkaqPFUS2wTJ2cw&m=jwMwtr2jshglWiDqQd4INhiCOlBiOfKYOkwSnr1z3kQ&s=M8vdEx7eERfm8L0gajLI1yASRQs7Y-SF7pj-Noc0i0s&e= oVirt Code of Conduct: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ovirt.org_community_about_community-2Dguidelines_&d=DwIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=2Fzhh_78OGspKQpl_e-CbhH6xUjnRkaqPFUS2wTJ2cw&m=jwMwtr2jshglWiDqQd4INhiCOlBiOfKYOkwSnr1z3kQ&s=-PJUsKbNKY3GRhGSr1PFiarA4QmH7wS6JsSKnwtAJvc&e= List Archives: https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.ovirt.org_archives_list_users-40ovirt.org_message_TTFYAEIUXIDQ3DD7NM6XBF33QXYONLXL_&d=DwIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=2Fzhh_78OGspKQpl_e-CbhH6xUjnRkaqPFUS2wTJ2cw&m=jwMwtr2jshglWiDqQd4INhiCOlBiOfKYOkwSnr1z3kQ&s=fD_BeZlUQn5017aujyhz5eBMzq6egoo9rUmxAMSZvak&e=
