VMware vSphere: Create a linked clone with Powercli

11 Comments

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: Cannot connect from vCenter Webclient to VDP Appliance

Leave a comment

Hi,

the license of VMware vSphere 5.1 includes the diskbased Backup Solution VDP(vSphere Data Protection). So I’ve decited to try the appliance (Version 5.1 Timestamp 2012-10-02) whether these meets our requirements.

Before I started, I ensured that

  • The DNS forward and reverse resolution of the choosen name and IP address is possible.
  • The User, who manage the backup, have vCenter Administrator rights.
  • all prerequisites are fulfilled

Downloading and installing of the appliance works as expected. The Appliance is properly registered in the vSphere Webclient but I can’t start the VDP Frontend within.

Error Message

Error: Could not connect to the requested VDP appliance. Would you like to be directed to the VDP configuration screen to throubleshoot the issue.

But whats wrong? I’m currently logged on to the Webclient with my Domain Login. When I’m using SSO Administrator admin@system-domain Login the VDP Frontends starts,
also another Domain Login can connect. Something in the chain Windows Domain, Single Sign On, vCenter and VDP Appliance fails.
