Moved to Fuga

Moving my VPS from VMware to Fuga was successful. First I copied the VMDK from the ESXi host to a Fuga instance with enough storage:

scp ./

And then converted it to QCOW2 with qemu-img:

qemu-img convert -O qcow2

Next step was mounting it with guestmount:

guestmount -a /var/www/html/images/ -m /dev/sda8 /mnt/tmp/

And changing some settings, i.e. network and resolvconf. When that was done I unmounted the image:

guestunmount /mnt/tmp

And uploaded it to my Fuga tenant:

openstack image create --disk-format qcow2 --container-format bare --file /path/to/images/ --private

Last step was launching an OpenStack image from this image, I used Ansible for this:

- name: Launch OpenStack instance
  hosts: localhost
  connection: local
  gather_facts: no
    os_flavor: c1.large
    os_network: int1
    os_image: 5b878fee-7071-4e9c-9d1b-f7b129ba0644
    os_portname: int-port200

    - name: Create port
        network: "{{ os_network }}"
          - ip_address: "{{ os_fixed_ip }}"
        name: "{{ os_portname }}"

    - name: Launch instance
        state: present
        name: "{{ os_hostname }}"
        timeout: 200
        flavor: "{{ os_flavor }}"
          - port-name: "{{ os_portname }}"
        security_groups: "{{ os_hostname }}"
        floating_ips: "{{ os_floating_ip }}"
        image: "{{ os_image }}"
          hostname: "{{ os_hostname }}"

And a few minutes later I had a working VPS again. While converting and uploading I made the necessary DNS changes and by the time my VPS was running happily on Fuga all DNS entries pointed to the new IP address.

Moving to OpenStack

In the coming days I’m going to move the VPS on which this blog resides from VMware to the Fuga OpenStack cloud. Not because I have to but hey, if I can host my stuff on a fully open source based cloud instead of a proprietary solution the decision is simple. And Fuga has been around for a while now, it’s rock solid and as I have a lot of freedom within my OpenStack tenant I can do with my VPS whatever I want when it comes to resources.

Moving the VM will cause some downtime. I’ve opted for the solution to shut down the VM, copy it from the ESXi host on which it lives to a server with enough storage and the libguestfs-tools package so that I can do some customization and the python-openstackclient package so that I can easily upload the customized image to OpenStack. Then I need to deploy an OpenStack instance from that uploaded image, switch the DNS and my server should be back online.
