General notes on migrating from Elastichosts to Proxmox.

One way to do this:

Create Proxmox KVM and add any large disks needed
(e.g. if the server has a 100G /srv).

Stop all daemons on server.

rsync large directories (e.g. /srv, /opt, /home, /var)
from Elastichosts server to Fork Sand server.

Power off server at Elastichosts.

Set new Elastichosts API key.

Download main / image from Elastichosts to sf-001 server (or other node).
Just do this if the partition is 10G or less.

export EHURI=https://api.lax-p.elastichosts.com
export EHAUTH=NUMB3RS:PASS

# This copies the image from Elastichosts to Fork Sand:
./elastichosts-download.sh DISK-ID somename.img

# Then add that image to the Proxmox cluster (moves from local disk to Ceph):
qm importdisk [vm ID to attach to] [disk image from Elastichosts] [Ceph pool name]
qm importdisk 999 /home/jebba/somename.img krbd

# Then in the Proxmox web GUI attach the disk

# mount it in temporary system.

fsck.ext4 /dev/vdb1

mount /dev/vdb1 /mnt

chroot /mnt

# Set new IP address.
vim network/interfaces

# Power off

# Set new disk image as boot image, and boot.

# Check all ok.
