Questions tagged as ['hyper-v']

Microsoft Hyper-V is a hypervisor-based virtualization system for x86-64 systems. Hyper-V exists in two variants: as a stand-alone product called Microsoft Hyper-V Server, and as an installable role in Windows Server 2008 and later. Both variants are able to run in Windows Server Core versions.

Adding multiple virtual switches to New-VM?

I'm working on a Powershell script to create new virtual machines as part of a migration between a Hyper-V server running Hyper-V Server 2012R2 and a new Hyper-V server running Hyper-V Server 2019.

For the virtual machines that have one single virtual switch assigned to them, this script works fine, however, I have some virtual machines that have two switches. For those VM's, I get this message:  ...

When I revert my running VM (by selecting a the checkpoint it was at before booting and choosing 'apply'), I see the VM is saved for a few seconds first.

Can anyone explain why it saves the VM state rather than just 'killing it off somehow'?

hyper-v dynamic expanding vs fixed disk
