If you can't justify a /24 with a single hypervisor, you aren't being
creative enough. Seriously. Optimize your network _plan_ for address
consumption. You need a /29 (or two /30s) to connect each VM to the
primary and backup router VMs and that's before you assign virtual IPs
to web servers on the VMs.
In your initial allocation, ARIN won't hold you to your plan. You just
have to have a plan where the numbers add up to justified need. If
you're not comfortable going it on your own, contract someone who's
been through it before to shepherd you through the process. ARIN's
process is convoluted and arcane, but if you're ready to pay the cost
of multihoming you truly won't have any trouble justifying an ARIN
