Description

This is for offline resizing a VM, i.e. changing the MEMORY and CPU attributes. There are two different situations:
  • VM is not allocated to any host (HOLD, PENDING, STOP, FAILED). This way a resume or resubmit action will use the new values.
  • VM is allocated (POWEROFF). In this case additional checks for host capacity may be needed.

Note that changing the values in PENDING or POWEROFF may lead to the scheduler using the old values (VM capacity or host usage) if the change takes place during the scheduling phase.

Before changing any value quotas need to be checked.
