Compiling Zimbra server on Ubuntu 8.04LTS
Last version of Zimbra collaboration, version 6.0.6, had been subject to several delays, which lead to a gap of nearly three weeks since the first proposed release date. These dates are considered target, thus flexible. Normally, I wouldn’t get crazy about release dates. Yes, while you may wish to get your hands on, because it fixes the most annoying but you ever had, you can wait some more days anyway.
But 6.0.6 had several fixes I really needed at some place. And after the second delay, I decided to try to compile Zimbra from source. Brave you think? Me too…
10.16.10Convirt: transform a VM from HVM to PV
We recently reinstalled our main server. It’s a Xen 4.0.1 host, based on Debian Squeeze. We don’t have many VM on it, it’s basically to save some power and have a sandbox for some test installations. Can be useful, quite often.
Instead of using plain CLI tools (xen-tools basically), I decided to give a try to one of the most well known interfaces for Xen: Convirt. Formerly xenman, born some years ago, at some time it moved to a commercial software, with open source base. Can be installed on custom host, as in my case, or downloaded as VM appliance!
Beside all considerations, it’s quite cool, even if I find documentation a bit lacking, the forum has some nice people. Not really as much as I’d like, but useful.

Xen4 dom0 and Grub2
I’ve recently installed a Debian Squeeze system with Xen4. Since the pretty new mix of Grub2 and Xen, I’ve had little problems finding around how to apply the dom0_mem option to boot command line.
To add the usual dom0 options to kernel command line, just edit /etc/defaults/grub and add a line as follows:
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=256M nosmp"
After that, obviously run update-grub.
It wasn’t very hard, but found no examples so far. 
Samba-Vscan on Debian Lenny with Samba 3.2.5
samba-vscan is quite an old project, part of the OpenAntivirus Project, used to have Samba perform a virus check on files accessed by the clients. Unfortunately, this software is not mantained anymore, and while Samba is obviously progressing, making it compile is not an easy task.
