Re: Network Setup
Arbin, I have a little VCL playground set up on a Dell desktop configured similarly to what you described. The public network is on a vSwitch that routes through eth0, but it has a single static IP assigned to it so I don't use DHCP. The private network is only connected via a (different) vSwitch. I think the challenge will come in with the DHCP part. I believe the VCL software expects to manage the assignment of external IP addresses to VMs. In other words, it assumes a block of routable IPv4 addresses are assigned to it to manage. Hence a DHCP server on the external network would conflict with the VCL management of those addresses. Someone with more experience setting things up could tell you for sure but that is how I understand it to work.

Re: Network Setup
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Arbin, Generally, public addresses are handled by a DHCP server. However, if one it not available, VCL can manage the public addresses directly. So, VCL does not always expect to manage the external addresses. I'm not that strong with VMware, but I believe both the public and private networks will need to go through vSwitches. However, you should be able to set up those vSwitches so that they are both connected to the same physical NIC with one of them set up to be on a separate VLAN.

Network Setup
All, From the documentation, VCL has to have two networks, Private and Public. My question is can they be setup within VMware where the public IP can routed through the eth0 and get a DHCP address and the private IP can be routed through a vSwitch? Do all of you have two vlans provided by a physical switch? Any info would be helpful.
