Indeed, see also:

Another option is iSCSI, which AFAIU does not suffer from this problem.
And yet another option is using nested-kvm to run multiple virtual
"hosts" on a single physical one, and run hosted-engine on them, with
another VM serving nfs or iSCSI storage. This obviously provides lower
performance, but higher flexibility, and is probably ideal for learning
oVirt, testing etc. Obviously you can't create/maintain these hosts
using oVirt itself, but have to use e.g. virsh or virt-manager.
There is a project called lago  doing just that, and some of the CI
tests of oVirt already use it to do a full hosted-engine setup.
