For awhile now my file server has been running Fedora Core 6. I never have a good time to upgrade it to Fedora 7 because I'm always using it.

In the beginning I had envisioned running multiple VMs on it for compiling packages; it's an x86_64 box, so I would gain an arch (currently only i386) and would be to compile both the Intel architectures on one box. I'd free up space on my laptop since I wouldn't have 4 VMs sitting on it (that rarely work with VMWare anyway).

The problem has been that he Xen kernels have locked up my file server for awhile. I'm not sure when it started, but things would just hang when udev was starting.

The recent kernel-xen-2.6.20-1.3001 package seems to have fixed that though. So I setup a bunch of VMs one day and got them updated.

Well, all but a FC6 VM. For some reason I constantly have problems running that as a domU.

Unfortunately I then realized that my ivtv drivers weren't loading because there weren't any packages available. My file server also serves as my MythTV backend, so there was a day there were I missed some recordings. Axel's moving this week, so kernel packages have been stalled while he gets things situated. So, I'm back to a regular 2.6.22 kernel.

One thing I did notice is that the tickless support in 2.6.22 definitely helps on this server - it keeps things much cooler than the 2.6.20 kernel does.

Oh, and the VMs I'm running (or want to run) include:

Fedora Core 6 x86_64: not working

Fedora 7 x86_64: working

CentOS3.9 x86_64: wouldn't install

CentOS4.5 x86_64: working

CentOS5.0 x86_64: working

So I still need to get FC6 and CentOS3 installed, but things are going pretty well, I think. After the ivtv drivers are available I should be back to trying to get things going.
