Microsoft has revealed that the new preview series of confidential computing virtual machines, the DC-Series, which went into public preview overnight are based on Generation 2 (Gen 2) Hyper-V virtual machines. This is the first time that a non-Generation 1 (Gen 1) VM has been available in Azure.<\/p>\n

Note that ASR allows you to migrate\/replicate Generation 2 machines into Azure by converting them into Generation 1 at the time of failover.<\/em><\/p>\n

These confidential compute VMs use hardware features of the Intel chipset to provide secure enclaves to isolate the processing of sensitive data.<\/p>\n

The creation process for a DC-Series is a little different than usual \u2013 you have to look for Confidential Compute VM Deployment in the Marketplace and then you work through a (legacy blade-based) customised deployment that is not as complete as a normal virtual machine deployment. In the end a machine appears.<\/p>\n

I\u2019ve taken a screenshot from a normal Azure VM including a view of Device Manager from Windows Server 2016 with the OS disk.<\/p>\n

Note that both the OS disk and the Temp Drive are IDE drives on a Virtual HD ATA controller. This is typical a Generation 1 virtual machine. Also note the IDE\/ATA controller?<\/p>\n

Now have a look at a DC-Series machine:<\/p>\n

Note how the OS disk and the Temp Drive are listed as Microsoft Virtual Disk on SCSI controllers? Ah \u2013 definitely a Generation 2 virtual machine! Also do you see the IDE\/ATA controller is missing from the device listing? If you expand System Devices you will find that the list is much smaller. For example, the Hyper-V S3 Cap PCI bus video controller (explained here<\/a> by Didier Van Hoye) of Generation 1 is gone.<\/p>\n

If you found this information useful, then imagine what 2 days of training might mean to you. I’m delivering a 2-day course in Frankfurt on December 3-4, teaching newbies and experienced Azure admins about Azure Infrastructure. There’ll be lots of in-depth information, covering the foundations, best practices, troubleshooting, and advanced configurations.
