A revolutionary new feature of Fedora 12 is "Network Interface Management" via a library called netcf. With this library as the facilitator, it becomes possible for any tool, not just NetworkManager, to reliably and methodically configure network interfaces. The original impetus for this feature was to enable tools like oVirt and libvirt to manipulate the networks on the hosts which underlie virtual machines, and that's what I'll discuss below.

I recently took a trailer building class from the UC Davis Craft Center. We built a bicycle trailer out of 1/2" electical coinduit pipe. Based off the "flatsy" trailer from Community Bike Cart Design. Each of us did things a little bit differently, here is how I built mine.

I had an awesome (and painful) day riding the Tahoe Rim Trail from Tahoe Meadows down Marlette Lake where we had lunch. Then up the Flume Trail and finally down Tunnel Creek to our shuttle truck on Saturday. About 5 hours and 25 miles. Thanks to Myke, Nate, Steve, and Sean for making it an awesome day!

How to manually migrate a virtual machine from one host to another. The process is roughly: copy the guest config to the destination, create LVs on the destination, dd the LVs across ssh, instantiate and start the guest on the destination.

As I described in a previous post, I dedicate an LV in the host for each guest. The guest then uses LVM to manage the space. In this case the guest is contained in two logical volumes on the host.

How to migrate iTunes from one platform to another and retain links to your songs, even when they are stored remote to the iTunes client, and their path has changed.

Before
Windows laptop with iTunes 8.x. All (most) music is stored on a Samba server mounted at M:\media\mp3, rather than where iTunes wants you to put it. In Linux it's called freedom, in Mac OS it's called swimming against the stream.

After
Mac laptop with iTunes 8.x and All (most) music is stored on a Samba server mounted at /Volumes/media/mp3

If you've tried to fire up a chroot named on Fedora 11 you may have noticed it complains about missing configuration files such as named.dnssec.keys.

There is a bug that implies you should use SELINUX instead of chroot. But if you aren't ready for SELINUX, you can still run a chroot name server. Here is how.

After expanding a volume on the SAN, I needed Solaris 10 to now see that the disk has grown and make use of the added space.

Device slice c8t600A0B80002A39FC000004DE47E92C69d0 was 200G with
a filesystem on slice 6. On the SAN, I expanded the volume to 225G. Here is how to expand the disk or partition inside of Solaris.

The steps are:

1. Detect larger disk size and relabel disk.
2. Grow the filesystem to fill the disk.

I've never had the original, so I can confidently say this is "Better than Bailey's Irish Cream".

• 1 can coconut milk (14 oz)
• 2 Tbs Brown Sugar
• 2 Tbs Chocolate Syrup
• 2 tsp Vanilla Extract
• 3/4 cup (Irish) Whisky

After having my Sony Sat T-60 Series 1 DirecTiVo for about 8 years, I'm finally upgrading to a TiVo HD. It should be here soon, so in the meantime I need to do some research and prepare my home network for the addition.

To leverage my Mythdora MythTV box I want to support the following in Linux:

• Download video from TiVo to my MythTV
• Play video on the TiVo from my MythTV

Let's see how to do that...

Fedora 8 goes EOL next week, so it's time to upgrade. A yum upgrade is not the recommended way to upgrade, but it can work fine. The simpler a system is, the more likely this method is to succeed.

I just successfully upgraded my Fedora 8 text-only firewall and samba server using yum. Here are my notes from the process.
