Re: Help with external DHCP issue
Ah, this makes much more sense. Thanks Josh! I'll add the incrementally higher MAC address values and then edit dhcpd.conf and hosts files and we'll see what happens.

Re: Help with external DHCP issue
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Jeff, VCL will handle creating the virtual machines on the VMWare host. It manages both the vmdk and vmx files, and then registers/unregisters the virtual machines as needed. What it doesn't currently do is automatically create new virtual machines in its own database or dynamically assign virtual machines to VM hosts. This is what you should do next time you need to add virtual machines: * look at the highest MAC address assigned in the computers table * go to the Add Multiple Computers page, enter the MAC address that would come after what you looked up, and enter the rest of the information required on that page. * get the DHCP info and add it to your dhcpd.conf file * add entries to /etc/hosts for the virtual machines * go to the Virtual Hosts section of the site and assign the new virtual machines to VM hosts After doing that, vcld should be able to provision reservations for the virtual machines. Aaron/Andy: correct me if I missed anything.

Re: SSH service on Windows Base Image
Ryan, You can fix this issue by creating a user on the virtual machine (windows) called root. Make sure to give it a strong password, though.

To access normal user accout
Hi Some users want to reserve a virtual machine and access existing user account on the image. However, VCL post configuration seemed disable all other accounts which are on the image. How can I maintain the original account on the image? I check the NC state university VCL. It seemed that, VCL let user login the image by VCL account first, then user use internal network to login to other machine which has original user account on the image. Command is "ssh -l username linux" Thanks, Xianqing
Re: Help with external DHCP issue
I did use the "Add Multiple" for this, but I didn't put a MAC as we hadn't created virtual machines for these (and thus had no MAC to use). I created 10 computers using add multiple. I plan to create 10 virtual machines on the VMWare host and get their MAC addresses and add them to the 10 computers in the computer table that were created with add multiple. From what I understand, this should resolve it. Correct me if I'm wrong. To save some time next time, I'd have created the 10 virtual machines first, grabbed the first MAC address, and then used the "Add Multiple" with that MAC address. I'd still have to actually create (or clone) the 10 virtual machines though.

Jeff, The "Add Multiple" checkbox on Manage Computers->Edit Computer Information is designed to help with this. You should only need to enter the information on the "Add Multiple Computers" page that link takes you to one time to generate as many virtual machines as you want. Make sure you enter the start/end private IPs and the start MAC (also make sure to select available as the state as there's currently a bug preventing adding machines directly in the maintenance state). After submitting that page, you will also be able to generate the additional DHCP info for your dhcpd.conf file. You will need to enter the private IP of your management node to get that file. We have it slated for version 2.4 to dynamically manage the virtual hosts/guests for you.
