Introduction to Azure Gen 2 VM

After the most special Spring Festival in so many years, the rest has stopped, the meat has gone up and scared, and it's time to start doing some work. During the special period, I also hope that you will go out less, wash your hands frequently and wear masks.

This time, let's open our eyes to Global and take a look at some new services of Azure Global. First, let's take a look at some new features of Azure VM. This time, let's introduce Azure Gen 2 VM.

But now we can create the second generation virtual machine on Azure.

First of all, let's take a look at some of the functions of the second generation virtual machine in Azure and its comparison with the first generation virtual machine.

SCSIVM Siz

All VM sizes only support VmOS disks for advanced storage > 2 TB × √

Custom disk / image / exchange operating system √√ virtual machine size set supports √√ Azure site recovery √√ backup / restore √√ shared image library √√ Azure disk encryption √ x

Of course, some features of local Hyper-V Gen 2 VM are not supported in Azure either. They mainly include the following features:

Safe start

Protected VM

VTPM

Virtualization-based security (VBS)

VHDX format

So we can see that the much-anticipated vhdx is still not supported at present.

In addition, not all images can support Gen 2 VM,Azure images that can support Gen 2 VM, including the following. You can see that lower versions are not supported.

Windows Server 2019 、 2016 、 2012 R2 、 2012

Windows 10

SUSE Linux Enterprise Server 15 SP1

SUSE Linux Enterprise Server 12 SP4

Ubuntu Server 16.04 、 18.04 、 19.04 、 19.10

RHEL 8.0

At the same time, not all series of VM Size can support Gen 2 VM. The size that can support Gen 2 VM is as follows:

B series

DC series

Dsv2 series and Dsv3 series

Esv3 series

Fsv2 series

GS series

HB-ACCT-WC series

HC series

Ls series and Lsv2 series

Mv2 series

NCv2 series and NCv3 series

ND series

NVv3 series

We can see that some new models can support the second generation virtual machine.

In terms of the creation process, the only difference between the second generation virtual machine and the first generation lies in the last step. When choosing generation, we need to choose Gen 2, and the other steps are exactly the same.
