3CX Debian installation - no network interface to select

[Lars Köchling]

Hi there,

I'm trying to install the 3CX Phone System on a virtual Debian 9 64-bit System. The Debian installation is clean and up-to-date.
In the installation process I have to choose the network interface, but there is nothing to choose - I tried the web installation and the text based one.

My /etc/network/interfaces file looks like this:

auto lo
iface lo inet loopback

# Auto generated venet0 interfaces

auto venet0
iface venet0 inet static
address 127.0.0.1
netmask 255.255.255.255
broadcast 0.0.0.0
up route add default dev venet0

iface venet0 inet6 static
address ::2
netmask 128
up ip -6 r a default dev venet0

auto venet0:0
iface venet0:0 inet static
address *here is my public ip address*
netmask 255.255.255.255

Can anybody help me to fix this issue?

Can Debian see any NICs?

Sounds like a Debian problem rather than a 3CX one.

What virtualization method are you using?

ifconfig -a shows the following output:

What virtualization method are you using?

I think my provider Strato is using Virtuozzo - but I'm not sure.

 

[cobaltit]

That is likely the problem. I believe the only virtualization platforms are HyperV, VMware and KVM.

Agree with cobaltit.

If I could point you to this thread:

"As the general idea of this hyper visor is of an abstract layering of instances the instance it self does not have a NIC we can see or bind to..."

I would advise deploying from the 3CX website in future. That way you know you're deploying into a tested environment.

Did you install Debian from the ISO from 3CX?

From his initial description no, but it doesn't matter... 3CX doesn't work on Virtuozzo.
