Preparation de l'image disk

/root/tools/images/build-openstack-debian-image --image-size 20 --release jessie  -u http://apt.tetaneutral.net/debian/ -s http://apt.tetaneutral.net/debian/ --no-dhcp -e acpi-support --output maposmatic --hook maposmatic-hook.sh
mv maposmatic.raw /maposmatic.raw

Setup de la VM

virt-install --name maposmatic --vcpus=4,maxvcpus=8 --memory 8192,maxmemory=16384 --network bridge=br-eth0,model=virtio --nographics --serial pty --wait -1 --noreboot --autostart --disk /maposmatic.raw,bus=virtio,cache=none,io=native --disk /dev/sdb,bus=virtio,cache=none,io=native --disk /dev/sdc,bus=virtio,cache=none,io=native --import
<pre>

Modification du xml pour les trucs non pris en charge par virt-install:

<pre>
virsh edit maposmatic

# Pour chaque bridge ajouter, le vlan et openvswitch comme ceci:
    <vlan><tag id='3132'/></vlan><virtualport type='openvswitch'/>

# Pour ceph, remplacer:

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source file='/maposmatic.raw'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </disk>

# Par:

    <disk type='network' device='disk'>
        <driver name='qemu' type='raw'/>
        <source protocol='rbd' name='ssds/maposmatic-disk'>
                <host name='192.168.99.101' port='6789'/>
                <host name='192.168.99.102' port='6789'/>
                <host name='192.168.99.103' port='6789'/>
        </source>
        <auth username='openstack-service'>
            <secret type='ceph' uuid='1fe74663-8dfa-486c-bb80-3bd94c90c967'/>
        </auth>
        <target dev='vda' bus='virtio'/>
        <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </disk>
</pre>

puis import du disque dans ceph

<pre>
rbd -p ssds import /maposmatic.raw  maposmatic-disk
</pre>

Boot de la VM

<pre>
virsh start openstack
