[SOLVED] Assign multiple VLAN (IP) to a virtual machine

[sharbich]

Hello,
how can I assign multiple VLAN (IP) addresses in my VM?

I want to assign different VLAN IP addresses to the VM on a single network interface?

 

[ce3rd]

make sure your vmbr0 bridge is vlan aware - add it to the vm - make the vlan interfaces in the VM operating system.. ;-)

 

[sharbich]

The virtual machine "102" is only assigned an IP address from VLAN 140. Not from VLAN 200.
However, the Proxmox host psme02 gets an IP from VLAN 200. Just not the VM 102.

I'm not entirely sure if you understood the mechanics of networking in Proxmox or Linux in general.
@ce3rd already had an idea fitting your request that you attach a vlan-aware bridge to your vm and create all vlan-interfaces (with multiple ips as you asked for) inside your vm. This way you just need to attach one bridge to the VM.
You can also attach multiple network adapters using the same VLAN-Tag and assign the IPs in the VM like that. But that would be inconvenient IMHO. Depends on your network design.

I have the following entry in the "/etc/network/interfaces" directory of VM 102. What do I need to add to get an IP address assigned from VLAN 200?

root@freepbx:~# cat /etc/network/interfaces
# Diese Datei beschreibt die auf Ihrem System verfügbaren Netzwerkschnittstellen
# und wie man sie aktiviert. Weitere Informationen finden Sie unter interfaces(5).

Quelle /etc/network/interfaces.d/*

# Die Loopback-Netzwerkschnittstelle
auto lo
iface lo inet loopback

# Die primäre Netzwerkschnittstelle
Hotplug zulassen ens18
iface ens18 inet dhcp

These are the network settings on the Proxmox host:

root@psme02:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

If your VM has it‘s NIC on vmbr0 and you added the appropiate tag (200) on the vNIC interface within the GUI everything else depends on your network setup (DHCP reachable for VLAN 200 etc.).

 

[fstrankowski]

Do you have a DHCP Server in VLAN 200?

 

[sharbich]

I was able to solve my problem.
I created a bridge on the Proxmox server that includes all VLANs:
see Appendix 1
In the data center under the Proxmox host in the VM, I had to create another network device with the VLAN tag 200:
see Appendix 2
After that, I was able to create in VM 102 another interface in the "/etc/network/interfaces" directory, which then received an IP address from VLAN 200 via DHCP:

root@freepbx:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug ens18
## iface ens18 inet dhcp
iface ens18 inet dhcp

allow-hotplug ens19
## iface ens19 inet dhcp
iface ens19 inet dhcp

I still dont understand why you create vlan-bridges on your node and use the vmbr0 with tagged frames in your vm. But you do you, glad its working for you.

Please be so kind and change the thread to [SOLVED]. Thanks

Then I don't understand what you mean? What do I need to configure on my node? Which network device do I need to create on the VM, and what look like should my interface file on the VM?

 

[Wichets]

Use can add vlan to vm use multiple nics
and tag vlan id and setting static ip to vm with no default route.
