[ UPDATE ] Some person in the DC doesn't had the necessary skills to perform the right switch configuration. So after sent him a link to a CISCO forum shew up the issue, other person managed to fix the issue [this procedure is close!]
Hi there.
Guys I have a strange problem.
I have 2 proxmox and it has several network cards.
I took 1 on each server, 1G and created a vmbr1 with this NIC eno4.
2 vms with Ubuntu with 2 network cards:
1 - WAN using vmbr0
2 - VLAN tag 100 using vmbr1
The problem is that when vm1 is on serverA and vm2 on serverB I have to leave it without VLAN Aware.
When I migrate vm1 from serverA to serverB the connection from vm1 to vm2 stops.
I have to go there on vmbr1 in Networks to remove the VLAN Aware and then it works ping etc.
Sometimes it only works when you remove and install the vmbr1 network card firewall. Note that there is no firewall rule.
But when I switch vm1 back to serverA, I have to put vmbr1's VLAN Aware again.
Any tips?
