VM commands
This feature is supported only on the SR6600 RPE-X5E MPU.
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
In standalone mode:
add cdrom vm slot slot-number vm-name cdrom-file cdrom-file
In IRF mode:
add cdrom vm chassis chassis-number slot slot-number vm-name cdrom-file cdrom-file

Parameters
chassis chassis-number: Specifies an IRF member device by its member ID. (In IRF mode.)
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.
cdrom-file cdrom-file: Specifies the operating system image or driver 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 slot 0 centos7 cdrom-file slot0#sda1:/centos7.iso

Parameters
chassis chassis-number: Specifies an IRF member device by its member ID. (In IRF mode.)
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.
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 running VM, you must restart the VM for the configuration to take effect. If you add a disk to a stopped VM, the configuration takes effect after you start the VM.
Examples
# Add a disk in QCOW2 format to VM centos7.

Parameters
chassis chassis-number: Specifies an IRF member device by its member ID. (In IRF mode.)
slot slot-number: Specifies an MPU by its slot number.
vmname: Specifies a VM by its name. The vm-name argument is a case-sensitive string of 1 to 30 characters.
vcpuindex vcpu-index: Specifies a vCPU core by its index. To obtain the vCPU core index, use the display vmcpupin command.
cpuindex cpuindex: Specifies a physical CPU core by its index. To obtain the physical CPU core index, use the display vmcpupin command.
Usage guidelines
If you bind multiple vCPU cores of a VM to only one physical CPU core, the VM might fail to start up because of CPU resource conflict. As a best practice to ensure correct VM startup, bind the vCPU cores to different physical CPU cores.
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.
Examples
# Bind vCPU cores 0 and 1 on VM centos7 to physical CPU cores 2 and 3, respectively.
<Sysname> system-view
[Sysname] vmm
[Sysname-vmm]set vcpupin vm slot 0 centos7 vcpuindex 0 cpuindex 2
