What’s (not so) new in vSphere5 – Part 2 (VM Management)

In part 2 of my “What’s New in vSphere5″ series I focus on VM Management which covers the new functionality added surround a virtual machine. As you might expect the capabilities of the VM have been increased spawning a new VM Hardware Level 8.

VM Capabilities

  • 32 vCPUs
  • 1TB RAM
  • 3D Graphics and HD Audio
  • USB 3.0 with upto 20 storage devices connected
  • Smart Card Reader support
  • VM DirectPath IO Version2
VM Snapshots
  • vSphere4.1 introduced a new “Quiescing” option which requires that VMware Tools is installed. That’s something I just noticed by playing with vSphere4.1 and then vSphere5.1
  • A new “consolidation” button has been add to the VM menu. This automates the consolidation of many snapshots, and used to clear snapshots which might not have been cleaned up properly by other processes. This merely consolidates multiple snapshots into one snapshot, it does not delete and commit the snapshot.

  • Snapshots are still composed of memory (.vmsn), management (.vmsd) and delta (.vmdk) files. The delta VMDK file still grows at 16MB increments.
  • VMware recognize that unchecked snapshots can grow and take up disk space – they recommend cloning a VM to a new location; moving other VMs with cold migrate or Storage vMotion; or moving ancillary VMs to free space on a volume if it becomes full. Of course, you could add more capacity to a volume as well.
