Hi Domien, As far as I understand (I'm not a Veeam expert), if you are taking backup by connecting Veeam to the Engine API, after receiving the backup request the Engine application will request the KVM host to provide the items to backup. That communication from Engine to KVM and backwards will go through the ovirtmgmt network. If you are backing up VMs by using an agent installed on VMs, your VMs must have access on that backup VLAN you mentioned. I recommend you to talk to your Veeam backup support to confirm this.

We have an OLVM setup (version 4.5.5-1.42.el8) with 3 hosts in 1 cluster for now. Each host has a 1Gbps NIC pair in a seperate management LAN that is only used for ovirtmgmt Each host also has a 10Gbps NIC Bond where all the VLAN's are trunked including a dedicated Backup VLAN. The hosts do not have an IP in this Backup VLAN configured (is this needed?) Each host also has 2 NICs dedicated to storage backend (iSCSI Multipathing) Our Veeam Appliance and workers are setup in the Backup VLAN and they can communicate with the backup repository that is also in this VLAN. When we take a backup, however, we see that the ovirtmgmt network is maxed out on trafic, which probably shouldn't happen. We come from a VMWare environment where the backup proxies handle all the trafic through the backup VLAN without relying on the management network and I was expecting it to work similarly Has anyone managed to get this working as I envision it? Or is the solution to simply link ovirtmgmt to the 10Gbps bond and skip the dedicated mgmt networking? I've also opened a ticket with Veeam for this, but for now I'm just getting questions from them and no real answers. If I get a useful solution from them I will also post it here _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://urldefense.com/v3/__https://www.ovirt.org/privacy-policy.html__;!!ACWV5N9M2RV99hQ!Ou5tZKByCUJMHeCAh-afW6DpaXvWtn621OiDcBNT5i85iKGmXDKH2XAregJWcCf-jzc9LxqccnHsJJBgCw$ oVirt Code of Conduct: https://urldefense.com/v3/__https://www.ovirt.org/community/about/community-guidelines/__;!!ACWV5N9M2RV99hQ!Ou5tZKByCUJMHeCAh-afW6DpaXvWtn621OiDcBNT5i85iKGmXDKH2XAregJWcCf-jzc9LxqccnE_nQh3Xg$ List Archives: https://urldefense.com/v3/__https://lists.ovirt.org/archives/list/users@ovirt.org/message/CSBYRUEGDM3W3TDHFXAHAGDBN4GQOJY7/__;!!ACWV5N9M2RV99hQ!Ou5tZKByCUJMHeCAh-afW6DpaXvWtn621OiDcBNT5i85iKGmXDKH2XAregJWcCf-jzc9LxqccnGajIBZvw$ _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/BUFV4C32R3RIJGU6KDGWUXN2LSRO54AC/
