I don't think IBM would see you a new license for z/VM 6.1 on a z9, but if you have an existing z/VM version 5 license with Subscription and Support, you're entitled to version upgrades at no extra charge. Read the fine print in your license agreement. You shouldn't expect support for z/VM 6.1 on a z9, but you might be entitled to run it there. Just don't expect it to run well. Dennis

And, as Rob has pointed out, performance would in all likelihood be perfectly horrible.
