This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it’s often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).
I do not issue any guarantee that this will work for you!

How to clone virtual machines in VMware ESXi
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.
via How to clone virtual machines in VMware ESXi.
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.

Convert a VMWare Image to VirtualBox Image
Convert VMWare image called centos.vmdk to /tmp/centos.bin
$ qemu-img convert centos.vmdk /tmp/centos.bin
Now use VBoxManage to get back image in native format:
$ VBoxManage convertdd /tmp/centos.bin centos.vdi
How to Convert a KVM to a VDI
KVM is a bare metal virtualization software use to run several operating system on the same hardware. VDI is the file type used in VirtualBox, Sun Microsystems’ desktop virtualization product. A desktop virtualization product allows you to run an operating system in a window independent from your main operating system. VirtualBox and KVM use different file formats to store the virtual machine and transferring a KVM virtual machine to VirtualBox requires an indirect approach.

Reassign a vswif to a new vmnic
VMware doesn’t like having two service console connections with different IP addresses in the same subnet, so I have two options.
1. Create a service console connection in a different subnet and access the host from that subnet using the VIclient.
2. Enter the commands directly on the host console.I recommend option two. Keep in mind that this process temporarily disrupts network communications to the host via the service console IP.
After obtaining physical access to the host’s console (or network access via a DRAC or ILO), log in and su – to establish root.
