Without venet, I don't have any IP Address. It's only static IP, so I need to add a venet ?

venet -> you need to configure ip in proxmox gui
veth -> you need to configure ip inside the container (static or dhcp)

OK, if I add veth, how can I configure the IP of my VM if the VM have no ip address ??

You already have a nic added. You don't need to add anything else. Boot into your VM. Configure your IP there

jsenzier · Sep 29, 2014

So I have to use the console mode to configure the ip address of my VM ?

PS : I've attached the network map to be more explicit. I want to configure VM 1,2 and 3 to access to Internet by the address 10.0.0.1 (eth0 is connected to 10.0.0.0/24) and the VM 4 to access to Internet by the ip address 192.168.0.1 (eth1 is connected to 192.168.0.0/24)

I added the VETH "eth0" linked with the bridge vmbr1 in my VM.

But, when i start my VM, in /etc/network/interfaces, there is no eth0 !

Any idea ?

you need to defined it manually

auto eth0
iface eth0 inet static
address X.X.X.X
netmask X.X.X.X
broadcast X.X.X.X
gateway X.X.X.X

or

auto eth0
iface eth0 inet dhcp

It doesn't work, I add the configuration in /etc/network/interfaces

auto eth0
iface eth0 inet static
address 10.0.0.189
netmask 255.255.255.0
broadcast 10.0.0.255
gateway 10.0.0.1

I restart networking service :
service networking restart

root@test:/# ifconfig

But on the local network, when I ping my VM from my computer on 10.0.0.153 :

adda@D2SS35J:~$ ping 10.0.0.189

From 10.0.0.153 icmp_seq=4 Destination Host Unreachable

And, no Internet access for the VM.

And, no Internet access for the VM.

The conf seem to be ok inside the container.

Can you do a

#brctl show

on your host ? (to see if the veth is correctly plugged on the bridge)

jsenzier · Sep 30, 2014

This is the result of brctl show :

root@proxmox:~# brctl show
bridge name bridge id STP enabled interfaces
vmbr0 8000.74d4359ba5b0 no eth0
vmbr1 8000.000acd2414d3 no eth1
veth100.0

Ok, seem to be good.

So, are you sure that your eth1 is plugged on the same switch/vlan than your client computer ?

jsenzier · Sep 30, 2014

No, there are on 2 differents switchs.

Just to be sure, are the 2 switchs linked together ?
