ESXi Struggles

Published by at 10:21 am under architecture,Virtualization,VMware,Windows

I’ve finally built my new virtual server — the one in which I’m going to consolidate my current machines as virtual machines. The intention is to measure the amount of energy my current systems (consisting of a Sun Ultra 60 — dual 400MHz UltraSPARC II CPUs, 2GB memory, and 2x20GB SCSI drives; a Dell Workstation 610 — dual 700MHz Pentium III CPUs, 768MB memory, and a 20GB IDE drive as well as a 30GB IDE drive; a home-built server with an AMD Athlon 1.2GHz CPU, 512MB memory and a 30GB IDE drive as well as a 9.1GB SCSI drive) and then migrate everything to the virtual machine world and measure the energy used by the VM server.

The VM server consists of the following hardware:

Seasonic SS-500ES 500W power supply
Gigabyte GA-MA790GPT-UD3H
AMD Athlon x64 X4 CPU 630 Propus 2.8GHz (quad-core, 95W)
8GB memory
1 x 160GB 7200RPM SATA drive
1 x 500GB 7200RPM SATA drive

The first idea was to install Windows Server 2008R2 core with Hyper-V on the machine and use that to build the VM images. However, the Athlon x64 X4 CPU is not supported by Hyper-V. So far as I can tell it does use AMD-V technology and I did enable virtualization in the motherboard BIOS but Hyper-V won’t start. So, the fall back was to go with ESXi.

I wanted to use ESXi 4.0 Update 1 however the network interface on the motherboard (consisting of a Realtek 8111/8168 chip) is not supported by ESXi. The only supported network interfaces are gigabit interfaces (which the Realtek is — it just isn’t supported and I didn’t have a supported interface card on hand). So, I figured no problem…I’ll just use ESXi 3.5 Update 4. Well, the Realtek chip is also not supported in ESXi 3.5 — but the PCI 3Com 905TX and an Intel EE Pro 10/100 are. However, SATA drives are not supported — well, not completely. I managed to get the system installed by booting from the CD, switching to the tech support console (hitting ALT-F1) and then logging in using the unsupported login. I then loaded the AHCI driver and restarted the install and ESXi installed nicely. However, booting off the install on the hard drives was a no-go since the AHCI drive wouldn’t load (for reasons I’m not sure of) and the system crashed. Back to square one.

I then noticed that VMware released Update 5 to ESXi 3.5 earlier this month (about two weeks ago). I read the release notes and realized that they had resolved the AHCI/SATA drive issues. I downloaded it, burned it to a CD and tried it. Bingo! It installed without a hitch and booted without a problem. Awesome. Now I’m in the process of building out my VM images.
