The status of this item has been moved back to Under Review. We initially planned to move to VHDX support as part of our support for HyperV Gen2 VMs, but we ended up using the VHD format for Gen2 VMs as well. Some aspects of the Azure Infrastructure do not cleanly support VHDX OS or data disks. So this feature is dependent on some of these internal services being updated which is an ongoing process.Anonymous commented
It's kind of embarassing to MS that Azure doesn't support VHDX, drives over 1TB, and many other Hyper-V premium features. It makes Microsoft's cloud story a lot less persuasive. Glad I wasn't an all-in early adopter and only used Azure when it made direct financial sense. Though even then, I'm running into obstacles with ASR. Luckily I have other options. I feel bad for those that thought "Cloud First" was anything other than a marketing slogan and an excuse to not work on the on-prem System Center, Exchange, and SharePoint, and instead force customers into inferior and more expensive cloud offerings.
