[PVE-User] How to configure which network is used for migration

[Uwe Sauter]

Good morning,

I'm currently replacing one PVE cluster with another. The new hardware has a bunch of different
network interfaces that I want to use to separate VM traffic from Corosync/Ceph/migration traffic.

Is there a way to configure the interface/network that is used for migration or does this depend on
the combination of hostname resolution and which hostname was used to create the cluster?
(I have various hostnames configured per host, for each configured network one, so that I can
explicitly choose which interface I use to connect to a host.)

Regards,

	Uwe


Interface configuration:

eno1np0 --+-- untagged VLAN X -- Corosync ring 1/management network (192.168.1.0/24)

eno2np1 N/C

enp3s0  --+
          +-- bond0 --+-- bond0.100 -- vmbr100 \
enp4s0  --+           +-- bond0.101 -- vmbr101 +-- VM traffic
                      +-- bond0.102 -- vmbr102 /

enp5s0  --+
          +-- bond1 --+-- untagged VLAN Y -- Corosync ring 0/Ceph (172.16.1.0/24)
enp6s0  --+
