My Plan for things to do on the Workmeeting: (could and should be translated some time)

Was will ich tun

concrete tasks I have to do




Interesting thing:

I'm looking for ways that help me to chose between different virtualization solutions.

At the same time, I realized in these days, that I very much like the way of xen-tools to handle the disks - a filesystem is created directly inside a lvm volume, and a single partition (as opposed to a block device) is handed over to the guests.

I did believe it's not possible to reuse such lvm with partitions inside other virt solutions. But that's wrong - you can boot such a thing in qemu with:

henning@xnote:~$ sudo qemu -kernel /boot/vmlinuz-2.6.18-6-686 -initrd /boot/initrd.img-2.6.18-6-686 -hda /dev/mapper/data-skolelinux--test--disk  -append root=/dev/hda
Could not open '/dev/kqemu' - QEMU acceleration layer not activated

It might sound odd to use something that looks to qemu like a full block device as root filesystem - but it works, and it's only for my testing and development systems on the laptop. Fine.

Also found another interesting thing about deleting lvm volumes - sometimes, they are stil open and cannot be removed. dmsetup must be used to shut them down completely.

I also finally have some sid Xen VM's where I can, hopefully build openjdk-6 - let's see what happens...

(ambitious) plan for tomorrow
