This article mainly introduces how to install OVMPlatform Installation, the article is very detailed, has a certain reference value, interested friends must read it!

OVM-V1.5 has just been released, adding support for VMwareEsxi nodes, merging the management platform and computing nodes into an iso. At the same time, from this version, the installation platform can be directly used as an All-in-one, and only friends of one machine can experience it! As a result, the problems of many partners have been solved. In addition, USB disk installation is supported from the OVM1.5 version.

Management platform installation OVMPlatform Installation1, installation preparation Preparations

OVM products are in the form of ISO with names such as: ovm-platform-1.5.iso

If installed on PC, you can do so by:

(1) make USB boot disk. Use the tool to make a USB boot disk (you can use UltraISO to make a bootable U disk), write the ISO into the U disk, set up the USB device in BIOS to start the installation.

(2) start with USB. Carve the ISO into a CD, use the USB CD-ROM drive, boot from the CD-ROM drive in BIOS and start the installation.

If installed on the server, in addition to the above two, you can also use:

(3) enter the BMC configuration home page from the server BMC IP, and use the virtual optical drive in BMC to mount the ISO. In BIOS

Set to boot from the CD-ROM drive and start the installation.

Note: when booting through a flash drive, it may boot to dracut, indicating that / dev/root does not exist. Solution:

Dracut:# cd / dev / / enter the dev directory

Dracut:# ls / / list all the hard disk devices in the system and find the drive letter corresponding to the USB disk. This is sda.

Dracut:# reboot / / restart the system, press TAB to enter the centos installation path configuration, and manually add the USB disk to the startup path: change vmlinuz initrd=initrd.img quiet to: vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sda4quiet

Press enter to continue to enter the OVM installation interface.

Attention here:

Many articles on the Internet say that this step is changed to "> vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sdb".

Quiet "what, and then failed cd/dev command to check USB drive letter and so on, come on, I just wasted a lot of time here, all the devices under the dev directory tried a few times but failed, mainly there are two laptop hard drives, coupled with USB drives, so that I really do not know which device is which ah.

So here we directly change the text that comes out after pressing the TAB key to: > vmlinuz initrd=initrd.img linux dd quiet. Enter after the correction, and then your equipment list will be listed. In this list, I can clearly identify which is our physical equipment if I don't understand Linux.

Continue to repeat the above vmlinuz initrd=initrd.img quiet to: vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sda quiet step directly to the system installation interface
