[PVE-User] Dedicated Migration Network?

[Phil Kauffman]

I am resubmitting this to the user list after a conversation with Thomas 
Lamprecht <t.lamprecht at proxmox.com> during the proxtalks conference.


Is setting up a dedicated migration network a configurable?
How can I get this working?

 From what I have seen online I found this hack: 
https://forum.proxmox.com/threads/how-to-separate-migration-network-dirty-fix.21538/

# diff QemuServer.pm usr_share_perl5_PVE_QemuServer.pm.erb
4295c4295
<               $migrate_uri = "tcp:${localip}:${migrate_port}";
---
 >               $migrate_uri = "tcp:192.168.2.162:${migrate_port}";

This hack does not seem to work either.

Even after specifically setting up my cluster like so:
   pvecm create bravo \
       -bindnet0_addr 192.168.2.164 \
       -ring0_addr bravo-vmnode2-coro.example.com

   pvecm add bravo-vmnode2-coro.example.com \
       -ring0_addr bravo-vmnode1-coro.example.com

The 192 network is a bonded 10G interface with a vlan.


After creating the cluster it seems that proxmox ignores my request and 
does the following:

# cat /etc/pve/.members
{
"nodename": "bravo-vmnode1",
"version": 4,
"cluster": { "name": "bravo", "version": 2, "nodes": 2, "quorate": 1 },
"nodelist": {
   "bravo-vmnode1": { "id": 2, "online": 1, "ip": "10.135.164.162"},
   "bravo-vmnode2": { "id": 1, "online": 1, "ip": "10.135.164.164"}
   }
}

The 10.135 network is only 1G and only supposed to be used to access the 
web interface.

My dns is setup like so:
bravo-vmnode1.example.com has address 10.135.164.162
bravo-vmnode1-coro.example.com has address 192.168.2.162
bravo-vmnode1-priv.example.com has address 192.168.1.162

Each network is dedicated to a particular task. The 192 networks are 10G.

Attached is also a sample of the proxmox nodes /etc/network/interfaces file.

Any insight or links to documentation would be very helpful.

Cheers,

Phil
