To get access to the RHEV-M 3.0 beta, you must have an active Red Hat Enterprise Virtualization subscription. Go to this RHN page to see links to the beta channels. See this page for discussion around the beta. This is the official announcement.
I received the 2 x HP microservers and the 8 GB RAM upgrades today. Although I don’t yet have the disk upgrades (expected next week) I can make a start installing standard RHEL on one of the servers. I’m going to install RHEV-M into a virtual machine on this first server, but I can’t install that yet without the disk upgrade.
Performing the memory upgrade is relatively simple. Once about 5 cables are removed, the motherboard slides right out:
Because these machines have no CD drive, I used PXE to install RHEL 6.1 (on the first server only):
For clarity, this is what I’m expecting the installation to look like right now (I may change my mind in future though …)
