vMotion

Question 1

What are the three types of vMotion migration?

Answer 1

Cold Migration - Powered off VMs and can be used to move to different datacenters
Migrate a Suspended VM - VM is suspended, can move to different datacenter
Storage vMotion - used to move the storage of a POWERED ON VM

Question 2

What are the host requirements for vMotion

Answer 2

• ESXi hosts must be licensed to use vMotion.
  ■ ESXi hosts must have VMkernel networking established for the vMotion traffic.
  ■ ESXi hosts must be licensed to use vMotion and/or Storage vMotion.

Question 3

What are the virtual machine requirements for vMotion

Answer 3

■ Virtual machines that use raw disks for clustering cannot be migrated.
■ Virtual machines that use a virtual device backed by a device that is not accessible on
the destination host cannot be migrated.
■ Virtual machines that use a virtual device backed by a device on the client computer
cannot be migrated.
- Virtual machines that use USB pass-through devices can be migrated, but only if the
devices are enabled for vMotion.
■ Virtual machines that use NPIV are not supported with Storage vMotion.
■ You can vMotion virtual machines that utilize NPIV, only if the RDM files are all
located on the same datastore.
■ Virtual machine disks must be in persistent mode or be RDMs for Storage vMotion.
■ Virtual machines in the process of having a VMware Tools upgrade cannot be
migrated.

Question 4

What are the EVC requirements?

Answer 4

• All hosts in the cluster must have only Intel or only AMD processors. Mixing Intel and
  AMD processors is not allowed.
  ■ CPU features, such as hardware virtualization support (AMD-V or Intel VT) and
  AMD No eXecute (NX) or Intel eXecute Disable (XD), should be enabled consistently
  across all hosts in the cluster.
  ■ All of the ESXi hosts in the cluster must contain supported CPUs for the desired
  EVC mode
