★ Installing CAStools for the VM

After installing an operating system for the VM, you must also install CAStools for the VM for the following purposes:

·            Obtain CPU usage, memory usage, and process monitoring information about the VM.

·            Provide the drivers that are required for the VM to use high-speed disks and NICs.

For the compatibility of CAStools and operating systems, see H3C[ge1]  UIS Server Virtualization Software and Hardware Compatibility.

1. Installing CAStools for a Linux or Windows operating system

(1) Log in to UIS, select the VM, and then click Edit.

(2) Click the CD-ROM tab, and then click Connect.

(3) Select Install CAStools from the Type list, and then click OK.

(5) If the operating system type is Linux, log in to the operating system as a root user, and then execute the following commands:

The root password is what you specified during operating system installation.

[root@localhost~]# mount /dev/cdrom /media

mount: /dev/sr0 is write-protected, mounting read-only

[root@localhost~]# cd /media

[root@localhost media]# ls

2. Installing CAStools for a FreeBSD operating system

(1) Log in to the operating system as a root user.

The root password is what you specified during operating system installation.

(2) Based on the FreeBSD ISO image file, execute the following commands to install pkg and python:

root@:~ # mkdir /dist

root@:~ # mount –t cd9660 /dev/cd0/dist

root@:~ # setenv REPOS_DIR /dist/packages/repos

root@:~ # pkg bootstrap

The package management tool is not yet installed on your system.

3. Verifying the installation

This section uses a VM installed with a CentOS7.2 operating system as an example.

To verify the installation:

(1) Enter the summary information page of the VM.

(2) Verify that the operating system type of the VM is Linux, the operating system version is CentOS Linux release 7.2.1511 (Core), the CAStools state is running, and the CAStools version is 7.1.0.0[ge1] .
