Migrate machine

[kenny82]

Hello,
I have proxmox in HA, it has multiple network cards (different networks). My question is if there is a way that if a network goes down, the machines that use it can migrate to another proxmox, can it be done?

thank you so much

Hi @kenny82 no, ha is currently only triggered when your corosync-ring0 has a problem. Theres a feature request to have multiple conditions that could lead to a ha-scenario. Like when vm-network is down on one node, use the storage-network to live migrate to the other hosts, where the vm-network is still alive.

Currently when your vm-network goes down, nothing will happen regarding ha, vms just dont have a network.

Heres the bugreport: https://bugzilla.proxmox.com/show_bug.cgi?id=4122

Improvements would be:

• Switch to ring1 when ring0 has high latency (instead of rebooting the node ...)
• Do Live-Migration if one of your desired networks is done (and is not on the other nodes)
  • VM-Network, Ceph-Network, Backup-Network for example
