1.7 Attributes That Can Be Changed Dynamically
A dynamic change does not require a reboot of the guest in question. The following attributes
can be changed dynamically:
• CPU
— Adding or removing guest vCPU entitlement. The default is uncapped mode. In
uncapped mode, this is also automatic based on overall “free” entitlement.
— Enabling or disabling vCPUs from within a guest.
• Memory
— Adding or removing the memory in use by a guest. This can also be made automatic
with AMR (Automatic Memory Reallocation) based on overall "free" memory.
• Network
— Adding or removing virtual switches (vswitches) on the VM Host.
• Storage
— Adding or removing storage to or from a guest.
NOTE: Depending on the type of storage being used, there may be additional steps
required. See Section 6.2.1.5 (page 100)
• Migration
— Migrating a guest online.
NOTE: Before you add or remove memory, networking, or storage from a guest, be sure you
know if further action is required on the guest. For example, if you add storage to an OpenVMS
guest, you must issue the following command on the guest, SYSMAN IO AUTO.
