This entry written by skx contains some perl code which I hope will be filtered:


#!/usr/bin/perl -w

use strict;
use warnings;

print "Hello, world\n";

# this code is syntax highlighted, unless there is a bug ;)

Blog Demo

This is a sample blog. There are a couple of demos you can view, each showing the same output for different themes:

A much more complete demo site would be the authors own blog, which is powered by the most recent release of Chronicle. You can find that here:

Xen Migration
12th August 2007

Xen Migration

This afternoon I mostly migrated Xen guests from their old host to their new. (As part of a an upgrade of facilities. Upgrading in place would have been much fiddlier and more annoying!)

The migration took almost three hours, which was longer than anticipated but shorter than I'd feared. In the future I'll know to do it differently, but I managed to script it fairly well after the first couple were done manually.

Everything appears to be working correctly so I will soon nip out for some high quality beer.

life
12th August 2007

The life that I have
Is all that I have
And the life that I have
Is yours

The love that I have
Of the life that I have
Is yours and yours and yours.

A sleep I shall have
A rest I shall have
Yet death will be but a pause
For the peace of my years
In the long green grass
Will be yours and yours and yours.

Multiple IPs for Xen
10th March 2007
Xen Help?

One thing that I wanted to do with the new host was track bandwidth usage upon a per-guest basis.

This should be possible with something like vnstat - however solutions counting traffic by interface name are not a good mesh with Xen - since by default a guest will have an interface with a name like 'vif20.0' - and no means of mapping that to a specific guest.

Each of my guests has been allocated three IPs which are defined like this in the Xen configuration file:

Configuration file

Unfortunately anything else I've tried to give each IP a static interface name fails. I've seen reports of this online but no solutions.

Given a configuration file like this the Xen guest doesn't receive any traffic upon the second + third address:

vif = [ 'ip=1.2.3.4,vifname=foo1',
        'ip=1.2.3.5,vifname=foo2',
        'ip=1.2.3.6,vifname=foo3' ]

Any suggestions welcome.
