Xen Stats Revised
by David Kowis on Mar.08, 2010, under Linux, W00t!
I had reimplemented some monitoring on my network and then I got to wondering if there was a revised version of the original xen-stats stuff I was using. Turns out there is. The site details instructions on how to set it up in cacti, and it works pretty well. I do wish there was a single graph to collect all for the hosts, instead of individual host graphs, but it’s not bad. Perhaps I’ll build a template that uses the data source and glues them all into one graph. But it provides reasonably accurate data, and it’s not difficult to set up.
(The UPS graphs I need to fix too, somethings broken in the PHP datasource it uses. So if you’ve got a reliable Network UPS Tools graphing source for cacti, other than this one, lemme know.)
Xen 3.4.2 rpms for Fedora 11 x86_64
by David Kowis on Nov.12, 2009, under Linux, W00t!, fedora
I was using xen 3.4.1 on my fedora 11 Domain0, but I couldn’t ever suspend anything. xm save always failed. Someone on IRC suggested that it was the guest kernel that was to blame. Turns out it was xen 3.4.1.
After many hours searching the intertubes for a srpm or a spec file for building xen 3.4.2 for fedora, I decided that I would hack an existing one to 3.4.2 and hope for the best.
It built after I removed a few patches. The patches mostly complained about being already applied, so I assume the bugs the patches were addressing were fixed in 3.4.2. I have generated rpms for x86_64 and put the spec file up on my site. Enjoy.
Migration proceeding
by David Kowis on Sep.01, 2009, under Linux, W00t!
The new cpu coolers fit and I can highly recommend them. The loudest fan on the server is the 5-drive sata hot-swap bay. I’ll make a posting detailing the server and the pitfalls I encountered for others on the internet, if any others actually read this, heh.
Anyways, the migration is proceeding, I have 10VMs running on the xen host. I have a few more to build to get the rest of my services segregated enough. I’m using LDAP on a VM to have centralized authentication and authorization. It’s still evolving slowly, but I can get the services I need running on a vm as they were, and then build a new VM to start the LDAP integration. Xen rules.

I’ll post pictures of it when I get around to building it (hopefully today.)
I has a G1

Yep. I played with one in the store, and then I had to buy it. So there went most of my dollars. I’m too tired to really talk a whole lot about it right now, but needless to say if you’re reading this, you should buy me the android book from my favorite publisher so that I can build you a freaking awesome application.
