A while ago I thought it would be a good idea to make a backup of my Linux server by just dumping the complete disk to a file. In retrospect, it would have been much easier had I just dumped the individual filesystems.

Note: If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain. If you place two reflectors on an AP with two antennas you will see an additional increase in performance.
For this project you are going to need scissors, a utility knife, some adhesive putty and an empty beer can. More than one empty beer can is acceptable but don’t kid yourself, the router only needs the one.

This is the tricky step. Unlike VMware Server, the Infrastructure Client does not have the File > Open option, allowing you to browse for existing .vmx configuration files and registering them. So it seems you might be stuck.
The answer lies in the datastore. In the destination folder, where you have just created your clone, right-click on the .vmx configuration file. Select Add to Inventory.

Update: This indeed worked. The problem occurs in that if a .vmx file is copied directly from Workstation, it can contain erroneous info that can cause problems. In my case eth0 would not pass traffic. I noticed something wrong by examining the virtual machines on Configuration -> Networking when the esxi box is selected. I noticed the vm I was having problems with wasn’t listed so I thought to examine the .vmx file.
The copied over .vmx file had ethernet0.vnet=”/dev/vmnet0″ which is a Workstation reference that doesn’t apply to esxi. By eliminating this and adding ethernet0.networkName = “VM Network” networking worked.
In our case, we selected physical computer but notice all the different sources you can import virtual machines from. You could import an existing virtual machine, a physical machine that this program is running on, or a remote machine over the network.

VI API is a Web Service and XML interface focused on management of virtual machines and ESX server configuration.
VCB offers command-line tools to integrate with backup products on SAN.
The VDDK is focused on efficient access and transfer of data on virtual disk storage. The VDDK can be used in conjunction with other APIs to offer a complete integrated solution for management of virtual infrastructure.
Dynamic disks were first introduced with Windows 2000 and provide features that basic disks do not, such as the ability to create volumes that span multiple disks spanned and striped volumes, and the ability to create fault tolerant volumes mirrored and RAID-5 volumes.
Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. Because each dynamic disk in a computer stores a replica of the dynamic disk database, Windows Server 2003 can repair a corrupted database on one dynamic disk by using the database on another dynamic disk.

I am unsure as to why this is done at the OS level.

I found this marketing speak funny in that I had no idea what View was after reading that. After perusing the site more it does look useful. VMware wants to be gatekeeper to a business’ computing infrastructure and View looks like the end user portal. Will download to see how this works.
