[SOLVED] Proxmox cluster not using Link 0 to migrate VMs

[itret]

Hello.

Does anyone know why proxmox cluster uses Link 1 instead of Link 0 to migrate VMs?
My Link 0 is 10G network card and Link 1 uses 1G card.
I was wondering why migration is so slow so I checked NIC traffic with vnstat and I noticed proxmox cluster data goes thru backup link.
Is there anyway to force it to use Link 0?

here is pretty good explained. you configured the wrong network.

Under "Datacenter --> Options --> Migration Settings" you can specify which network to use ;-)

OMG! Thank you so much!
Why isn't it set by default?

Why isn't it set by default?

Until some time ago this explicit option wasn't available at all, if I remember correctly.

Probably the default is simply to use "the first network, which works"...

Best regards
