VM commands
This feature is supported only on the following MSR routers:
· MSR3610-I-DP.
· MSR3610-I-XS.
· MSR3610-IE-DP.
· MSR3610-IE-XS.
· MSR3610-IE-ES.
· MSR3610-IE-EAD.
To ensure correct operation of VMs, make sure the storage medium where the VMs are installed has sufficient storage space.
If removable hard disks or USB flash drives are used, make sure their file system format is EXT4.
add cdrom vm
Use add cdrom vm to add an operating system image or driver image to a VM.
Syntax
add cdrom vm vm-name cdrom-file cdrom-file
Views
VMM view
Predefined user roles
network-admin
Parameters
vm-name: Specifies a VM by its name. The vm-name argument is a case-sensitive string of 1 to 30 characters.
cdrom-file cdrom-file: Specifies the image file path. The cdrom-file argument is a case-sensitive string of 1 to 63 characters. The file must be an .iso file.
Usage guidelines
The device supports a maximum of four CD-ROMs. CD-ROMs can contain operating system image files or hardware driver image files.
The CD-ROMs and IDE disks share drive names hda, hdb, hdc, and hdd. When you add a CD-ROM or IDE disk to a VM, the VM randomly assigns a drive name to the CD-ROM or IDE disk.
If you use this command on a running VM, you must restart the VM for the configuration to take effect. If you use this command on a stopped VM, the configuration takes effect after you start the VM.
Before using a newly added CD-ROM, specify a boot order number for it. CD-ROMs that contain operating system image files always have higher boot priority that those containing hardware driver image files. The same type of CD-ROMs boot according to the priority of their boot order numbers.
If you do not change the boot disk or uninstall the images of a CD-ROM after the CD-ROM is installed, the CD-ROM will no longer be used for booting.
When a VM is deployed, the VM automatically assigns a boot order number of 8 to the CD-ROM that contains the operating system image file. To replace the operating system images, perform the following operations:
1. Add a new CD-ROM that contains the new operating system image file.
2. Set the boot order of the new CD-ROM to take precedence over that of the original CD-ROM.
3. (Optional.) Add a new hard disk as the boot disk of the VM.
Alternatively, you can remove the CD-ROM that contains the current operating system image file and add the CD-ROM that contains the new operating system image file to the VM.
For more information about boot order configuration, see "set bootorder vm." To view the disk boot order, use the display vmdisklist command.
Examples
# Add an operating system image to VM centos7.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm] add cdrom vm centos7 cdrom-file hda0:/centos7.iso

Views
VMM view
Predefined user roles
network-admin
Parameters
vm-name: Specifies a VM by its name. The vm-name argument is a case-sensitive string of 1 to 30 characters.
format: Specifies the disk format.
raw: Specifies the RAW format.
qcow2: Specifies the QCOW2 format.
disk-file path-file: Specifies the disk file path. The path-file argument is a case-sensitive string of 1 to 63 characters. The file must be a .qcow2 or .raw file.
disk-bus: Specifies the disk bus type.
ide: Specifies the Integrated Device Electronics (IDE) bus type.
virtio: Specifies the virtio bus type. For some operating systems (for example, Windows Server 2008/2012 or FreeBsd), you must install a driver for this bus type.
Usage guidelines
Before you add a disk to a VM, you must use the create-disk command to create the disk.
After you add a disk to a VM, you must partition and format that disk on the guest OS before you can use it.
A VM supports the following bus types of disks:
· IDE—IDE disks and CD-ROMs share disk drive names hda, hdb, hdc, and hdd. The VM randomly assigns a drive name to an IDE disk or CD-ROM.
· Virtio—The drive names of virtio disks are vda, vdb, vdc, and vdd. The VM randomly assigns a drive name to a virtio disk.
A VM supports a maximum of four disks for each bus type. However, a vFW VM supports only one disk.
When a VM is deployed, the VM automatically assigns a boot order number of 1 to its boot disk. To change the boot disk, you can perform the following operations:
1. (Optional.) Add a new disk to the VM.
2. Modify the boot order number of the original boot disk.
3. Assign the new boot disk a boot order number that has higher priority than that of the original boot disk.
For more information about boot order configuration, see "set bootorder vm." To view the disk boot order, use the display vmdisklist command.
If you add a disk to a VM on a running VM, you must restart the VM for the configuration to take effect. If you add a disk to a VM on a stopped VM, the configuration takes effect after you start the VM.
Examples
# Add a disk in QCOW2 format to VM centos7.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm] create-disk hda0:/centos.qcow size 30 format qcow2

network-admin
Parameters
vm-name: Specifies a VM by its name. The vm-name argument is a case-sensitive string of 1 to 30 characters.
type type: Specifies a device type. The value of the type argument can be usb or pci-serial, which represent the USB type and PCI serial type, respectively.
slot slot-number: Specifies the number of the slot that hosts the physical device to add.
index index-number: Specifies a USB device by its index. The value of the index-number argument is fixed at 0.
vid vid-id: Specifies the vendor ID of the USB device, a hexadecimal number in the range of 0 to fffe.
pid pid-id: Specifies the product ID of the USB device, a hexadecimal number in the range of 0 to fffe.
Usage guidelines
To add a physical device to a VM deployed in a version that does not support USB device pass-through, first perform the following tasks:
1. Execute the uninstall vm command to uninstall the VM.
2. Execute the install vm-name command to reinstall the VM. Do not change the disk file path when you reinstall the VM.
For the USB type, the device can pass through only storage and serial devices to VMs, and you cannot extend interfaces to add more physical devices. If a USB device is absent, you can specify its vendor ID and product ID to add it. After the USB device is installed, the VM can use it directly.
If you specify the PCI serial type, you can add only the SIC-4RS interface module.
If you use the add hostdev vm command on a running VM, you must restart the VM for the configuration to take effect. If you use this command on a stopped VM, the configuration takes effect after you start the VM.
Examples
# Add a USB device to VM centos7.

Predefined user roles
network-admin
Parameters
pfid: Specifies a physical NIC by its PF ID. The value for the pfid argument is 0.
vlan: Specifies VLAN forwarding mode. In this mode, a physical NIC matches incoming packets by VLAN tags and removes VLAN tags from the packets before sending them to VMs. A VM uses a main interface to communicate with a physical NIC operating in VLAN forwarding mode.
mac: Specifies MAC forwarding mode. In this mode, a physical NIC matches incoming packets by MAC addresses and forwards the packets to VMs. A VM uses a subinterface to communicate with a physical NIC operating in MAC forwarding mode.
Usage guidelines
This command is available only when physical NICs operate in SR-IOV share mode.
Use MAC forwarding mode if a physical NIC does not check the VLAN tags of packets, for example, when a VM uses a vFW subinterface to communicate with a physical NIC.
To use MAC forwarding mode, configure subinterfaces on VMs in advance. For more information about subinterface configuration, see Ethernet interface commands in Interface Commend Reference.
Examples
# Configure a physical NIC to operate in MAC forwarding mode.

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.
To ensure that VMs can start up after the device reboots, make sure the NIC interfaces added to VMs are the interfaces required by the configured NIC network mode.
