Virtual machines -checking VM plan

José Enrique González — Wed, 13 Sep 2006 10:45:06 GMT

Hi:

I am very naive to Integrity Virtual Machines, and I am planning to virtualize an rx4640 into two guests systems. As this server has just two internal disks, I think I could install my host OS on them (including both disks in vg00) and create two big logical volumes of the same size (lets say, one in each disk) to serve as virtual disks (and boot devices) for each guest, respectively. Is this approach correct and factible? Thanks a lot in advance for your comments!

You need two disks per host which holds primary and mirror boot disk. This will help you to keep system up and running even if one boot disk fails.

This will be a QA environment, so availabilty is not a major issue for me. What I am really concerned about is if a logical volume (enough in size) created in the VM host can act as a boot and vg00 virtual disk device for a guest VM.

Jose,

Yes - either a logical volume, a physical disk or LUN, or even just a file can act as the boot disk for the guest virtual machines.

As you have already surmised - performance and resilience will not be particularly good in this configuration.

Then yes you can do it.
