I had some trouble restarting a xen user domain tonight. The shutdown, destroy, console, and list xm commands were all simply hanging. I finally tried restarting the xend service which fixed the hanging problems. But when I tried to start the user domain that originally gave me problems I got this error message:

Error: Device 769 (vbd) could not be connected.
Device /dev/vg/lv is mounted in a guest domain,
and so cannot be mounted now.

Over the past few weeks I have increasingly found myself unhappy developing Rails applications in NetBeans 6. While I was initially happy with the productivity boost from moving from writing applications in nano to using a full IDE I found myself reverting to using nano. The reason was simply that NetBeans was putting too much load on my desktop system. The system isn’t exactly slow (Athlon 64 X2 4600+, 2GB RAM) yet when running NetBeans the system load was hovering between 4 and 5 making development tedious. Before trying NetBeans I had read a lot about various IDE’s and I decided to revisit that research. One consistent complement to Eclipse with RadRails was that the performance was snappy. I decided to give it a try, if for no other reason than to expand my Rails IDE experiences.

I've been noticing that between desktops, laptops, and servers that there have been a lot of updates over the last week. I've seen updates for KDE packages, CUPS, Avahi, PHP, PostgreSQL, and more. Some are security related and others I believe come from the gutsy-updates repository and are just newer versions. In any case it seems like a good time to check in on any systems and update them.
