I am looking at configuring either a Windows or Linux host to run GNS3.

Is it better to run VirtualBox to connect hosts for testing, or is it better to run the GNS3 host on a ESXi host with multiple NICs, and run virtual machines?

If running on a ESXi box, do you use a cloud per NIC, or do you need to use a MS Loopback interface?

Any assistance or links to other peoples setups would be appreciated.

I have run up to 10 simultaneous virtual machines (GNS3 WorkBench) on a MacMini (with 16GB RAM) - all 10 VMs talking to each other to create a fairly large topology

I would have installed ESXi on the Mac Mini If I had time, but I found VmWare Fusion (in spite of it's insistance of putting packet on the wire twice) did the job rather well.

And the Mac mini is a pretty decent PC in itself anyway. I run mine "headless" and it is quite as a mouse but packed with power.

[Edit: Re the multiple NICs - found I didn't need them. Just create as many VLAN interfaces as you want on the MAC mini and feed the traffic to the wired network on the correct vlans right up front. It does mean that you are dependant on a single trunk port going to the MAc Mini though]
