using ovirt-hosted-engine-setup you can choose a setup without
using the appliance. So you can scratch install your VM
BTW the ovirt-engine-appliacnce we build [1] is Centos based. Seems
like perfect candidate.
#install the appliance
yum install ovirt-engine-appliance
#and then run the setup
ovirt-hosted-engine-setup
choose "disk" in this stage
Please specify the device to boot the VM from (cdrom, disk, pxe) [cdrom]: disk
it will suggest the downloaded appliance automatically
See this wiki for reference

Neat! I was unaware of the HEA so I'm happy to learn of this offering.
However, my concern is focused more on a procedure that I presently can
only imagine looking something akin to:
1. hosted-engine --set-maintenance --mode=global
2. hosted-engine --vm-poweroff
3. ovirt-hosted-engine-setup ...
4. use the exact same host name and IP address
5. hosted-engine --vm-start
6. hosted-engine --set-maintenance --mode=none
Or perhaps:
1. create a new guest
2. inside run foo to deploy the HE packages
3. configure it be aware of existing HE
4. run bar manually or wait for the two HE's to sync their state, sort
of like a RAID mirror
5. power off the original HE guest and allow the new one to be the sole
provider going forward
My confusion may simply stem from having forgot much of the process when
I deployed my HE back in January this year. But I thought it best to
get started on the right foot for the simplest and/or best practice.
