Xen 4.0 and 4.1 packages for Ubuntu and Debian
by specialj on May.25, 2011, under Sysadmin, virtualization
Packages can be found here:
https://launchpad.net/~agent-8131/+archive/ppa/+packages
Design goals:
- packages created for xen 4.0.1 and xen 4.1.0
- packages mirror install of xen as closely as possible
- currently only hypervisor and utils are included (make xen and make tools)
- no rc.d scripts setup, that’s left to user
- should be installable and functional on Debian and Ubuntu and on several versions
- Debian lenny (hopefully), squeeze
- Ubuntu hardy (hopefully), lucid, maverick, natty
Things to work on:
- getting stubdom to compile so pvgrub is present
- testing on various systems and fixing dependencies and conflicts as needed
Fixing netbeans in ubuntu
by specialj on May.20, 2011, under Development, Ruby On Rails
Netbeans has some issues in Ubuntu 10.10 and 11.04. One of the most serious is that javascript syntax highlighting does not work. Another is that Rails 3 applications do not run or debug correctly. I found the solution to be going to “Tools – Plugins -Settings” and enabling the “Netbeans” update center. Then by going to “Updates” and clicking “Reload Catalog” I got an update for the update system. After that was installed an netbeans was restarted I got a lot more updates for plugins (15 or so). Once updated everything seemed to work as it should.

Attempting to package Xen
by specialj on May.17, 2011, under Sysadmin, virtualization
I’m not an expert at Debian packaging but I’ve been gotten tired of building Xen on every systems and losing the advantages that packaging brings like tracking file conflicts. So I decided to try and package Xen though I have had no luck so far. I am making slow but steady progress. I wanted to package both 4.0.1 and 4.1.0 so I could compare them. I’m finding that 4.1.0 has stability issues and switching between the two without packages is incredibly time consuming.
Working with Xen 4.1
by specialj on May.09, 2011, under Sysadmin, virtualization
I took a development box running Xen 3.3 on Ubuntu 8.04 and upgraded in to Ubuntu 10.04 and installed Xen 4.1.0 from source. I still believe Xen is the best open source virtualization solution. At some point I’ll have to write up my experiments testing KVM + libvirt but suffice if to say the performance and stability were unacceptable. However, while the performance of Xen is great, I have noticed some issues with Xen 4.1.0.
