YARNTUH: Hyper-V doesn’t have HA restart priority?

Yet another reason not to use Hyper-V
While fiddling around with the new Microsoft Hyper-V R2 beta, testing out CSV, Live-Migration and the lot, I suddenly realized that Hyper-V does not support restart priority in cluster (HA) situations. This could very well be my next big reason not to recommend Hyper-V to customers, as HA (clustering) is useless without restart priorities.
In the event of hardware failure, and VM’s being restarted on another Hyper-V clusternode, there’s no way in garantuing that your infrastructure VM’s (like Domain Controller, DNS, DHCP and SQL) will start before your applications (IIS, Exchange, System Center components).
This will most likely result in the system engineer restarting VM’s or services manually. That’s not how I like my IT: automated.
