Linux Bond + Linux Bridge (Not Working in VM)

[tanoojmehra]

Hi,
I'm facing an issue:

This is a screenshot of my Network Interfaces:

I have created bond0 by using eno1, eno2, eno3, eno4 without setting an IP Address on the bond.
After this, I've created vmbr0 using bond0 and my Private IP Range which is 172.15.200.1 (Gateway: 172.15.254.1)

I can update my Proxmox, Ping Google, Download Files, Connect CIFS / SMB to other servers, but I cannot gain Network Access on a Virtual Machine.
It cannot reach DHCP or Ping my Server. I've tried Ubuntu, CloneZilla, Windows, etc

Srceenshot of my Proxmox successfully pinging Google via Shell.

Also, I'm using RoundRobin, because my switch doesn't support LACP.
I was using Hyper-V before this and had no problem bonding my interfaces there.

Please help!

do you use vlan for your vm nic gui ? (as you have enabled vlan-aware option)
