title: VCL 2.2.1 - Further Steps if Using VMware

If you are using standalone VMware servers (i.e. ones that VCL did not deploy using xCAT), you first need to add the VMWare servers; then, you need to add the virtual machines. You can either add them individually (Adding Individual VMWare Servers/Virtual Machines), or if they have sequential hostnames and IP addresses, you can add them all at once (Adding Multiple VMWare Servers/Virtual Machines).

Once you have added at least one computer, you can get to the “Add Single Computer” page by going to Manage Computers->Edit Computer Information and clicking Add. You can get to the “Add Multiple Computers” page by doing the same thing but checking the “Add Multiple” checkbox.

Adding Individual VMware Servers

1. Click Manage Computers
2. Select the Add Single Computer radio button
3. Click Submit
4. Fill in the following:
5. • Hostname
6. • IP Address
7. • State - vmhostinuse {note}Double-check this because you will not be able to change it later{note}
8. • Owner - admin@Local
9. • RAM
10. • Processor Speed
11. • Network Speed
12. • Type - blade
13. • Provisioning Engine - xCAT 2.x Provisioning
14. • Click the checkbox under allcomputers
15. Click Confirm Computer
16. Click Submit
17. Select a VM Host Profile these VMware hosts will use.  See the VCL:VMware Configuration  page for more information about VM Host Profiles.  {info}You can modify the VM Host Profile later if needed{info}
18. Click Add Computer {info}The computer you just added isn't listed after clicking Submit. This is not a problem.{info}

Adding Multiple VMWare Servers

1. Click Manage Computers
2. Select the Add Multiple Computers radio button
3. Click Submit
4. Fill in the following:
5. • Hostname - the hostnames of all the computers must have a numerical part that is sequential, use a % as a placeholder where that part would be
6. • Start value - the first number of the numerical part of the hostname
7. • End value - the last number of the numerical part of the hostname
8. • Start IP Address - if using static public addresses, the IP addresses must be sequential; enter the first address here; if using DHCP, just enter something like 1.1.1.1
9. • End IP address - the last IP address of the sequence; if using DHCP, you'll need to enter something that would work out to the last address relative to Start IP Address (i.e. if adding 3 computers, use 1.1.1.1 for start and 1.1.1.3 for end)
10. • State - vmhostinuse {note}Double-check this because you will not be able to change it later{note}
11. • Owner - owner of the computer
12. • RAM
13. • Processor Speed
14. • Network Speed
15. • Type - blade
16. • Provisioning Engine - xCAT 2.x
17. • Check allComputers
18. Click Confirm Computers
19. Click Submit
20. Select a VM Host Profile these VMware hosts will use. See the VCL:VMware Configuration  page for more information about VM Host Profiles.  {info}You can modify the VM Host Profile later if needed{info}
21. Click Add Computers

Adding Virtual Machines

1. Click Manage Computers
2. Select the Add Multiple Computers radio button
3. Click Submit
4. Fill in the following:
5. • Hostname - the hostnames of all the computers must have a numerical part that is sequential, use a % as a placeholder where that part would be
6. • Start value - the first number of the numerical part of the hostname
7. • End value - the last number of the numerical part of the hostname
8. • Start IP Address - if using static public addresses, the IP addresses must be sequential; enter the first address here; if using DHCP, just enter something like 1.1.1.1
9. • End IP address - the last IP address of the sequence; if using DHCP, you'll need to enter something that would work out to the last address relative to Start IP Address (i.e. if adding 3 computers, use 1.1.1.1 for start and 1.1.1.3 for end)
10. • Start private IP Address - similar to Start IP Address, but for the private side
11. • End private IP Address - similar to the End IP Address but for the private side
12. • Start MAC Address - if mac addresses are sequential, with the first one being the private MAC address for the first computer, the second one being the public MAC address for the first computer, the third one being the private MAC address of the second computer, etc, you can enter the first one here and then have the option of generating data to add to your dhcpd.conf file later in the process. {note}For VMware virtual machines, the MAC addresses you choose must be in the range {color:#008000}{}00:50:56:00:00:00{}{color} {color:#008000}-{color}{color:#008000}{}00:50:56:3F:FF:FF{}{color}. Pay special attention to the upper bound of this range. {color:#ff0000}{}00:50:56:40:00:00{}{color} {color:#ff0000}-{color} {color:#ff0000}{}00:50:56:FF:FF:FF{}{color} are NOT valid VMware virtual machines.{note}
13. • State - maintenance
14. • Owner - owner of the computer
15. • RAM
16. • Processor Speed
17. • Network Speed
18. • Type - virtualmachine
19. • Provisioning Engine - VMware
20. • Check All VM Computers and newvmimages
21. Click Confirm Computers
22. Click Submit
23. If you filled in the private address fields and the Start MAC Address, you can now enter the private IP address of the management node that will be handling these virtual machines to generate information to add to your dhcpd.conf file.

Assign a VM to a Virtual Host

1. Click Virtual Hosts
2. On the VM Hosts tab, select the virtual host server added previously.
3. Click Configure Host, You should see VM limit set to a number along with the vm profile, two columns of VM's assigned to host and Unassigned VMs.
4. Adjust the VM limit to the desired number of vms you would like to run on this host. Warning please consult your hypervisor documentation for the recommended number of virtual machines to run concurrently for your virtual server configuration.
5. Select the virtual machine nodes from the Unassigned VMs: column. 
6. Click Add.
