Adding additional network interfaces to a VMware virtual machine

Adding additional network interfaces to a VMware virtual machine
I am running VMware 5.5.0 and I have just deployed a new virtual machine from an Ovf file but I can only install 4 network adaptors, I have seen before that there is a way to reconfigure the vm to allow you to add more network interfaces. Has anyone heard of this?

Is there a reason you need more than  four ?

What is the virtual machine version ?

What is the OS ?

What is the OVF ?

usually, limitations are based on the above.

10 is usually the maximum per VM.

The system is for a firewall and it uses separate nic for each network
The virtual machine version is version 4
The OS is Form of Linux
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
That is the issue. virtual machine version 4, only supports 4.

I would discuss this requirement with the vendor, that has provided the firewall.

it was only at virtual machine version 7.0 and later, that 10 nics per VM, were introduced.

Your VM was designed for ESX/ESXi 3.5.

Will this fix cause a problem? The only reason I am using this older Ovf is so that I can import an older config from my older system, but if you think it might come back to hunt me I will just use the newer Ovf that supports 10 Nicks and build my firewall config from scratch.

Use a newer version for the Hypervisor you are using.

A newer version of the appliance, may use VMXNET3 interfaces which perform better, and uses a more up to date virtual machine hardware version.

virtual machine version 4.0 support is ancient, e.g. ESX/ESXi 3.5!

Deploy OVF to Vmware Workstation 10/11.

Once deployed - upgrade VM H/w, edit VM settings.

Power off VM and create a new OVF from Vmware Workstation .

Deploy this OVF to vsphere environment. I hope it should work as well.

well if he wants to "hack" the vendors VMX file, just change 4 to 8 in the VMX file! (or convert, using VMware Converter!).

and then add as many nics, as you like from the GUI (up to 10!)

rather than use a modern new version of the appliance.

But as for what changes this is going to do, with the OS.....only you will be able to access, if it works!
Manmeet BhatnagarCommented:
You're right Andrew.

I was just suggesting if any level of customization is required could be performed that way, like creating your own appliance.
