+Pre-Installation:
+
+You need to install the VMware VI Perl toolkit installed on the VCL server
+
+Each vmware esx hypervisor requires a mounted NFS datastore named 'VCL'
+
+This same datastore needs to be mounted on the VCL server at /mnt/vcl/
+
+This NFS export needs to be exported (from the NFS server) at /mnt/export/
+
+This same datastore requires the following structure.
+
+[VCL]
+ /inuse (required)
+ /golden (required)
+ /imagename
+ imagename.vmdk
+ imagename-flat.vmdk
+ ...
+
+Image requirements:
+ All images used by this module must have names that begin with esx3-<anything you want>
+ ssh must be set to start on boot
+ ssh keys must be setup so that VCL can ssh into it
+ The image needs two NICs (eth0 is private, eth1 is public)
+ The IP addressing of the private (eth1) interface must be set to DHCP on boot
+
+
+VCL expects the blades to have a consistant private IP address. Go configure dhcpd.conf and in /etc/hosts manually
+
+
+Customize the module:
+
+This module expects the following three variables to be hard-coded at the top of the esx.pm file. Remember to character escape any special characters.
+
+$vmhost_username, $vmhost_password, $datastore_ip
+
+A note about datastore_ip. Because the module ssh's to the storage system directly instead of doing a cp over nfs, you need to set the IP of the datastore here. The datastore machine should be setup with SSH keys from the VCL ssh keys set as IDENTITY_blade_linux in the VCL conf file.
+
+Install the module:
+
+Do these once:
+1) Insert a row into the module table with `perlpackage` equal to 'VCL::Module::Provisioning::esx'
+2) Insert a row into the provisioning table with `moduleid` equal to the id of the entry from step 1 in the module table
+3) Insert a record into the 'vmprofile' table with the following guidelines
+ profilename: VMware ESX SAN
+ vmtypeid: link to anything valid ID from the vmtype table.
+ imageid: link to the "No Image" id in the image table
+ virtualswitch0: <name of your private virtual machine port group>
+ virtualswitch1: <name of your public virtual machine port group>
+
+Make VCL aware of your ESX hosts:
+1) For each esx hypervisor, which VCL should provisong virtual machine to, create an entry for that hypervisor by going to Manage Computers -> Edit Computer Information -> Add
+ Hostname <your ESX's hostname>
+ IP <your ESX's IP>
+ Type "blade"
+ Provisioning Engine: This doesn't matter
+ Computer Groups: Don't add the hypervisors to any computer groups
+
+2) For each esx hypervisor manually create an entry in the 'vmhost' database table with the following guidelines:
+ computerid: the id of the computer created in step 1
+ vmlimit: the max number of vms to have on this hypervisor
+ vmprofileid: the id of the vmprofile entry created in the "Do these once" secion step 3
+
+Create a virtual machine placeholder for each VM you would like to concurrently run. Do so by going to Manage Computers -> Edit Computer Information -> Add
+ Hostname: <the hostname of the vm when it is provisioned and turned on>
+ IP: <the public IP of the vm when it is provisioned and turned on>
+ Type: virtualmachine
+ Provisioning Engine: VMware ESX
+ Computer Groups: allComputers
+
+For each virtual machine, manually update the private IP, eth0macaddress (private), and eth1macaddress (public) for the placeholder virtual machine entries created in in the computers table during step (4)
+
+Add static entries in dhcpd.conf for the eth0macaddresses (private) for all computer placeholder entries
+
+Add similar entries for each compter placeholder to the /etc/hosts file to provide VCL with name resolution on these vms
+
+Finally, once all virtual machines placeholders have been created, 'assign' them to hypervisors by using the 'Virtual Hosts' area of your web interface.
+
+Now your hypervisors and virtual machines are setup, time to add an image:
+
+1) Create an entry in the image table.
+ name: esx3-<what you want>-v0
+ OSid: link to the fc9 entry on the OS table
+2) Create an image revision table with the imageid fromt the entry created in (1) and the imagename used in (1)
+3) Add the image revision to the allImages and allVMimages groups

+ the same for every instance of the VMWARE class, a class attribute
+ is used and the hash is shared among all instances. This also

+ once.
