– Identify the disk number for the USB disk inserted, usually you can find it from the “Name” and “Size” field.
Below eg: , We inserted a USB with 4.1 GB size (so as the identified: “disk2”.)
Open terminal and execute the following commands:
sh-3.2$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *120.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_CoreStorage 119.0 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: Apple_HFS Macintosh HD *118.7 GB disk2
/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: UNTITLED *4.1 GB disk2
– Unmount the disk
sh-3.2$ diskutil unmountDisk /dev/disk3
Unmount of all volumes on disk3 was successful
– write the ISO file to USB using dd command
sh-3.2$ sudo dd if=Downloads/ubuntu-12.04.3-desktop-i386.iso of=/dev/disk2 bs=1m

Download and install vCenter Converter on a windows machine. http://www.vmware.com/products/converter
Unfortunately this tool does not have a Linux / MAC version.
vCenter Converter
In case you see an error: “Permission to perform this operation was denied”, right click and run the program as Administrator.
Provide the source and destination information, the source is the physical server to be converted and the destination vCenter.

vCenter Converter
Follow the steps, to do the conversion , a temporary OS will be started on the destination, by default it try to get an IP address from the DHCP server so that it can connect to the source machine and fetch the files required. But in case if you don’t have DHCP server you might see error like: “Unable to obtain the IP address of the helper virtual machine” . Fix this issue by setting up a static IP to the helper virtual machine during the conversion setup. Basically the helper VM IP should be able to communicate with the source machine which needs to be migrated
vCenter Converter Static IP
Proceed with the conversion, the duration will be based on the size of the VM and the connectivity if it belongs to another site/LAN.
You may need to change the network configuration (eg: HWADDR) and the MAC address mapping (/etc/udev/rules.d) to get it connected.
