Debian P2V

Debian Physical to Virtual -- Brain dump; this is very basic...

Prepare

Create the Debian Virtual Machine which will receive the Physical Machine data

Code: shell

xen-create-image --hostname=...

Synchronise

Synchronize data at any time:

Code: shell

mount /dev/<path to disk image> /mnt rsync \ --verbose \ --archive \ --numeric-ids \ --hard-links \ --exclude=/tmp \ --exclude=/proc \ --exclude=/dev \ --exclude=/sys \ --compress \ --rsh=ssh \ <physical machine>:/ \ /mnt/ umount /mnt

Note: if the --delete option is used, we need to re-add the modules from the Xen Kernel afterwards...

Migrate

1. Shutdown all services but ssh on the source server
2. Synchronize (as above)
3. Free / change IPs from the source server
4. Mount / chroot to the disk image
   • Install libc6-xen
   • Cleanup fstab
   • ...
5. Unmount the image
6. Start the VM
7. Configure for pygrub
