I have a Dell PowerEdge 2950 and there are 3 SATA 7200 drives (2 x 1TB, 1 x 300GB) and one SAS 15k drive (1 x 300GB).
I want to install Ubuntu as the host OS with several guest OSes.
Should I install the host OS (Ubuntu) on the fastest drive? Or should one of the guest OSes be on the faster drive?
-1 for mentioning putting all the guests on the same disk. The I/O load will almost certainly be too high -- spreading the I/O load amongst available spindles makes much more sense if there's going to be more than a handful of guests. Also, if the host is only doing VM hosting, it's not going to benefit from speedy I/O nearly as much as the guests -- the OSes doing the real work -- will. – afrazier – 2012-01-27T15:01:06.290
