A Commodity XenServer: The XenServer Install
by admin on May.27, 2009, under Uncategorized
This is the second part in my Commodity XenServer series. Check out Part 1 here.
The XenServer Install
Now that I had the basic system stable and ready to roll, I fired up the XenServer install CD. (At this point, I was running a SATA hardrive, with an IDE DVD-ROM Drive.)
The installer would run fine up until the point where I had to choose where I wanted to install from. When I selected the local DVD drive, I would get the error message, “Base installation repository was not found at that location. Please check and try again.”
After searching the Citrix support forums, I found that other people were having the same issue, but nobody had any answers yet. So I did a ton of troubleshooting:
-I re-downloaded and burned another copy of the installer
-I tried installing via FTP and NFS
-I disabled all non-essential BIOS functions
-I removed all non-essential hardware
None of these worked, but I got a tip from the Citrix forums–That the issue probably had something to do with hard disks/SATA/IDE. So I tried disabling all unused IDE/SATA channels, which was a no go.
I then swapped out the IDE DVD drive for a SATA DVD drive and disabled all IDE channels on the motherboard–And it worked!
I posted my results in this Citrix forum thread.
As I’m looking at the thread, it looks like there is another workaround, without having to go to SATA: (From the thread)
After starting the install and selecting the keyboard …
1) Hit Alt+F2 to switch to another console window
2) enter “modprobe ide-generic” return
3] switch back to the install window by hitting Alt+F1
After I got this issue worked out, everything else fell into place, and I came up with a working XenServer 5.0 Update 3 install.
The only other issuing I am still having is that the onboard NIC is realtek, and I can’t seem to get working drivers–This is not a big deal though, since I threw in a Netgear NIC I had laying around, and then bought an Intel Pro dual-nic PCI card, which XenServer had drivers for out-of-the-box.
This wraps up the Xen-Server install, which I am happy to say is humming along just fine with 5 VMs currently active.

A Commodity XenServer: The Build + Specs
by admin on May.25, 2009, under Uncategorized
This is the first post of my Commodity XenServer series, where I will be describing my experience in putting together a Commodity XenServer.
First off, let’s take a look at the specs and a photo:
Specs
-An old, mid-tower Antec Case
- AMD Phenom 9850 Quad Core Black Edition
-Arctic Cooling Freezer 64 Pro 92mm CPU Cooler
-8GB 4 x 2GB Corsair DDR2 1066
-Western Digital Caviar SE16 SATA 640GB (SATA/7200 RPM/16MB)
-LITE-ON Black 18X DVD-ROM SATA
I was able to find the majority of the components on sale / rebates / discounted, etc. For instance, the CPU was a NewEgg Open Box for $83, instead of the retail price of $160+. This allowed me to get a pretty decent setup for my budget.
Here is a photo before the build

The Build, Stress Testing, & Overlocking
Overall, the physical build went fine. At first I wasn’t sure if the AC CPU Cooler was going to fit with the memory slots so close, but I was able to finagle it together.
I started off by running memtest86+ overnight, to make sure the memory was good–Although the testing went fine, I noticed the RAM was running at 800Mhz instead of the advertised 1066Mhz, but I left it alone for now.
I then installed Vista, so I could do some benchmarking and stability testing.
I wanted to do a bit of overclocking, (why else would you have a Black Edition Phenom, which features an unlocked multiplier?)
This is where I ran into the memory clock issue, which I will devote a future post to.
Suffice to say, the final result was a CPU overclock of 8%, to 2800 Mhz / Core, for a total of 11,200 Mhz. I know I could have OC’ed it more, but since it will be serving in a server role, I didn’t think the extra CPU vs. Power was worth it.
With the build and OC done, I went on to the XenServer Install, forthcoming.
