What it worked for me was:
1) Start a VM via "virsh"
define a virsh alias:
alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-
engine/virsh_auth.conf'
Check the host's vdsm.log ,where the VM was last started - you will
find the VM's xml inside .
Copy the whole xml and use virsh to define the VM "virsh define
myVM.xml && virsh start myVM"
If you cannot find the xml file of the vm then you van use virt install as
if you were running in plain KVM.
2) vdsm-client most probably can start VMs even when the engine is
down

You can use "hosted-engine" to start the HostedEngine VM in paused mode
. Then you can connect over spice/vnc and then unpause the VM. Booting
the HostedEngine VM from DVD is a little bit harder. You will need to
get the HE's xml and edit it to point to the DVD. Once you got the
altered HE config , you can define and start.

You are not expected to mix HostedEngine and other VMs on the same
storage domain (gluster volume).
