Parameters
vm vm-name: Specifies a VM by its name, 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 down the VM that occupies the most memory.
Examples
# Start VM centos7.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm] start vm centos7
stop
Use stop to shut down a VM.
Syntax
stop vm vm-name [ force ]

Parameters
vm vm-name: Specifies a VM by its name, a case-sensitive string of 1 to 30 characters.
force: Forcibly shuts down the VM.

CAUTION: Use the force keyword with caution. A force shutdown might cause data loss. |
Shutting down a VM requires an amount of time. If a process stops the VM from shutting down, you need to access the VM and manually close the process.
If no operating system is installed on a VM, you must specify the force keyword to forcibly shut down the VM.
Examples
# Shut down VM centos7.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm] stop vm centos7
suspend
Use suspend to suspend a VM.

suspend vm vm-name

Parameters
passthrough: Specifies the passthrough mode. In this mode, a VM uses the PF interface of a physical NIC for communication.
sr-iov: Specifies the SR-IOV share mode. In this mode, VMs use the VF interfaces of a physical NIC for communication.
Usage guidelines
For the configuration to take effect, you must save the configuration and reboot the device.
Examples
# Set the VM network mode to passthrough mode.
<Sysname> system-view
[Sysname] vm network-mode passthrough
# Set the VM network mode to SR-IOV share mode.
<Sysname> system-view
[Sysname] vm network-mode sr-iov
