Option Description

High Priority

On hosts running ESX/ESXi version 4.1 or later, vCenter Server attempts to

reserve resources on both the source and destination hosts to be shared

among all concurrent migrations with vMotion. vCenter Server grants a

larger share of host CPU resources to high priority migrations than to

standard priority migrations. Migrations always proceed regardless of the

resources that have been reserved.

On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts

to reserve a fixed amount of resources on both the source and destination

hosts for each individual migration. High priority migrations do not proceed

if resources are unavailable.

Standard Priority

On hosts running ESX/ESXi version 4.1 or later, vCenter Server reserves

resources on both the source and destination hosts to be shared among all

concurrent migration with vMotion. vCenter Server grants a smaller share

of host CPU resources to standard priority migrations than to high priority

migrations. Migrations always proceed regardless of the resources that have

been reserved.

On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts

to reserve a fixed amount resources on the source and destination hosts for

each migration. Standard priority migrations always proceed. However, the

migration might proceed more slowly or fail to complete if sufficient

resources are not available.
