[SOLVED] Round-Robin Bonding does not work with VM's

[potetpro]

Hi.

So i have now tried with 3 different sets of network cards, same result.

The proxmox hypervisor works just fine.

The VM wont get an IP unless I disconnect one of the network cables. And when i reconnect it, the VM looses connectivity.
I have seen alot of posts on this forum with people having the same result.

Has anyone got it working?

I have tried 3 different switches, both managed and unmanaged (smart & dumb)

balance-rr requires support on all sides of the bond.
If you want redundancy, use active-backup and if you want load balancing, use LACP if your switch supports it.

Ah shoot.
So i pratice there is no way to get 2gbit speed for faster VM migration? as none of the other bonding options allow for a faster than 1Gbit on a single tcp stream?

One followup question. We are using a 1 Gigabit uplink + VM network, and a 10GBIT Ceph storage network.
Is it possible to utilize the 10gbit network for VM migration?

Thanks for answering.

You can specify a migration network: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_guest_migration
