I use puppet to keep my machines in sync with each other. Our default configuration has haldaemon and messagebus (dbus) off. I ran into a problem when I tried to create a new vm and there was no option to use the shared phyical device (the bridge)
A talk I gave on using puppet. I cover installation and initial configuration. It is a talk not a tutorial though, when I get a chance I'll post a short tutorial...
A talk I gave on using kvm. I have a video on doing a live migration at the end of it (you tube). I use virsh to perform the migration and watch the movement with virt-manager.
On our kvm hypervisor we have several vm's using fibre channel for storage. The hypervisor has to see all the devices, but each device has it's own lvm so when the hypervisor boots, it tries to read all of them.
I was trying to get Songbird to recognise my ipod and it wouldn't because the ipod was automounted under /media. I put the UUID of the iPod_Control partition in my fstab. I used blkid to get the UUID of that partition.
After installing SRSS we tried to setup a gnome kiosk session. There were no prototypes for this installed. After scouring the net we only found an example of something that didn't work :-(.
We use a retired netapp as a backup with snapmirror. We don't have support on the device anymore and one of the disks failed. I took the drive out and discovered it was a SEAGATE ST3146807FC. I found this site that said it was possible to flash the firmware on a generic drive for use in a network appliance.
I prefer a dark theme. I've lived with thunderbird doing a bad job of that for a while. I finally decided to fix it. I found this page which had what I wanted.
It seems like the interface for creating modules has changed a bit, and udev is the way to go. Here is a short, quick and dirty module that creates /dev/pi with anonymous major and minor using udev.
