This is a short tutorial how to migrate an OpenVZ container to a KVM Guest. Some ideas have been taken from other tutorials (1 and 2), the other half has been extracted from grml-debootstrap which can generate a KVM guest by using debootstrap. # form where to where migrate # don't forget the trailing / on the source! export SOURCE=/srv/vz/private/xxxxxxx/ # an empty LVM volume! export DEST=/dev/mapper/vg0-myfirstvm # create some magic for grub/partion table echo 4 66 | /usr/share/grml-debootstrap/bootgrub.

Since our beloved OpenVZ virutalisation technology is not moving in a direction we are comfortable with, we are currently evaluation several virtualisation technologies. One the the possible options is KVM. This is not a full tutorial about KVM, there are many good tutorials already, e.g. ((https://www.lisenet.com/2016/getting-started-with-kvm-on-debian-jessie/)) or ((http://linuxnewbieguide.org/?p=1993)) or ((http://xmodulo.com/use-kvm-command-line-debian-ubuntu.html)) or ((http://wiki.libvirt.org/page/UbuntuKVMWalkthrough)) or ((http://www.cyberciti.biz/faq/how-to-install-kvm-on-ubuntu-linux-14-04/)), this is just a collection of some notes which I collected during the evaluation. General Documentation RedHat has some good KVM virtualisation documentation available at: https://access.

In case you are a CLI junkie as myself and want to restore some files from a time maschine backup manually with the CLI (or using the finder), you will notice that the restored files cannot be changed. The restored files are copied with an ACL on the time machine backup witch prevents changes to those files. You need to remove the ACL from the restored files: chmod -R -N restored-files/
