How do I create an new vm with the -location and -x (kickstarter) but
without booting it, because I need to edit the xml first before the
first boot.
Kind regards and best wishes,

Hi, currently you are not able to create domain with that disk
definition, with this command line:
--disk source_protocol=rdb,source_name=libvirt-pool/zimbra-dev-disk,\
source_host_name=ceph01.powercraft.nl,source_host_port=6789,\
target=vda,bus=virtio,driver_type=raw
you are able to create this definition:
<disk type="network" device="disk">
<driver name="qemu" type="raw"/>
<source protocol="rdb"
name="libvirt-pool/zimbra-dev-disk">
<host name="ceph01.powercraft.nl" port="6789"/>
</source>
<target dev="vda" bus="virtio"/>
</disk>
Currently there is no way how to specify <auth> on the virt-install
command line and also multiple source <host> elements.
How do I create an new vm with the -location and -x (kickstarter)
but
without booting it, because I need to edit the xml first before the
first boot.
Look at options "--print-xml" and "--dry-run", it depends on your
use-case. However, the installation process has usually two steps, you
need to keep that in mind.
By default virt-install creates two XML definitions, the first one is
used to install the VM, after the installation is finished and the VM
is rebooted virt-install will power off the VM instead of rebooting it
and redefines the VM with second XML definition witch usually lacks the
installation sources.
If you need to update the XML before installation you need to handle the
installation process by yourself. The --dry-run option can prevent
storage creation if you don't need to create any storage before the
actual installation. If the location points to some URL you will have
to also manually download vmlinuz and initrd.
So if the XML change can wait after the guest installation I would
recommend doing that but if you need the change to XML it would be
good idea to create Feature request to add that functionality into
virt-install.
Kind regards and best wishes,

You cannot use virt-install to manage any disks, it is used only to
create domain XML and install the VM. Virsh is a command line tool
for libvirt and there you can manage disks, however for ceph volume
creation is not currently implemented so you need to create them
manually.

I am having a hard time with this.
virt-install \
--connect qemu:///system \
--hvm \
--virt-type kvm \
--network=default,model=virtio \
--noautoconsole \
--name zimbra-dev.powercraft.nl \
--ram 6144 \
--vcpus=4\
--vnc \
--os-type linux \
--os-variant rhel6 \
--nodisks \
--noreboot \
--print-step all \
--dry-run \
--location http://ftp.tudelft.nl/centos.org/7/os/x86_64/ \
-x
"ks=https://raw.githubusercontent.com/Zimbra-Community/pgp-zimlet/stable/kvm/centos7-ext4.cfg"
This will output an xml with multiple stages/steps. I can manually add
the following to the steps with the following:
<disk type='network' device='disk'>
<driver name='qemu' type='raw'/>
<auth username='libvirt'>
<secret type='ceph'
uuid='ec9be0c4-a60f-490e-af83-f0f27aaf48c9'/>
</auth>
<source protocol='rbd' name='libvirt-pool/zimbra-dev-disk'>
<host name='ceph01.powercraft.nl' port='6789'/>
<host name='ceph02.powercraft.nl' port='6789'/>
<host name='ceph03.powercraft.nl' port='6789'/>
</source>
<target dev='vda' bus='virtio'/>
</disk>
However how do I import these xml steps so they are being executed.
I tried to use: virsh define zimbra-dev.powercraft.nl.xml and keeping
only the first domain definition, but booting does not work, since the
boot files are not downloaded by virt-install first.
Does somebody know a workaround.
And for long term can I pay somebody a small bounty to add this
functionality to virt-install. Ceph support would be appreciated...
Would be nice to hear how other users use ceph with virt-install?
Kind regards,
Jelle de Jong

Hi, currently you are not able to create domain with that disk

source_host_name=ceph01.powercraft.nl,source_host_port=6789,\

you are able to create this definition:
<disk type="network" device="disk">
<driver name="qemu" type="raw"/>
<source protocol="rdb"
name="libvirt-pool/zimbra-dev-disk">
<host name="ceph01.powercraft.nl" port="6789"/>

<target dev="vda" bus="virtio"/>
</disk>
Currently there is no way how to specify <auth> on the virt-install
