Parameters
chassis chassis-number: Specifies an IRF member device by its member ID.
slot slot-number: Specifies an MPU by its slot number.
vm-name: Specifies a VM by its name. The vm-name argument is a case-sensitive string of 1 to 30 characters.
Usage guidelines
Make sure the VM you want to start has been created on the device and the system has sufficient memory to start the VM.
Besides allocating memory to VMs, the system needs to allocate some amount of memory to run the VM plane. As a best practice to make sure the system has sufficient memory to run the VM plane, adjust the amount of memory allocated to VMs to a small number if multiple VMs start. If the memory is insufficient, the system automatically shuts off the VM that occupies the most amount of memory.
Examples
# Start VM centos7.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm] start vm slot 0 centos7
stop

Usage guidelines

|
CAUTION: A force stop might cause data loss. Do not force a VM down unless necessary. |
If a VM fails to stop because of an abnormal process, access the VM, manually close the process, and retry the stop operation.
If the VM does not have an operating system, you must specify the force keyword to force it down.
