VMware vSphere: Create a linked clone with Powercli

Hi,

linked clones have some advantages:

  • New virtual machines are rapidly deployed. The initial task is only to reference to a snapshot of an existing virtual machine. No virtual disk file(s) will be copied at this time.
  • They save disk space. Because only the space difference to the origin snapshot is allocated.

I found no option in the vSphere respective the Webclient to create one, but PowerCli provides this. Lets do it.
Connect to vCenter

Connect-VIServer vcenter.subdomain.domain.local

Define the virtual machine which is the origin of the linked clone, and the Snapshotname on which the linked clone based.

$sOriginVM="mastervm"
$sOriginVMSnapshotName="mastervm_linkedclone_snap"

VMware ESXi: Setting up NAT with a linux virtual machine

Hi,

other than the Workstation, VMware ESXi does not has the functionality to “NATting” virtual machines network traffic into a public network.

My approach to implement NAT is a virtual machine with a slimmed-down (Debian) Linux.

These virtual machine has two network interfaces. The first interface is connected to a vSwitch called “Public LAN” with access to the public LAN, the second interface is connected to a vSwitch which has no physical adapter attached to and is called “NAT Network”. On the NAT interface a DHCP server is assigning IP Addresses.

VMware Workstation: Boot a virtual machine from a USB drive/stick

The BIOS of the VMware Workstation does not support to boot from a USB drive or stick which is connected to a virtual machine.

But there is a workaround:-) Use the Plop Boot Manager. Download the latest ZIP File and extract the plpbt.iso file. This contains a CD image which starts plop boot manager. Connect the iso file as  a virtual CDROM to your virtual machine.
