Windows 10: Why does hyper-v virtaul machine log out after the host machine W11 is suspended/resumed?

Hi, Why does hyper-v virtual machine log out after the host machine W11 is suspended/resumed? https://onedrive.live.com/?cid=553558B76510538D&id=553558B76510538D%21sd80b0984f879434a9f93ecca164b73ef&parId=553558B76510538D%21106&o=OneUp Thanks in advance. Regards, Jose Luis

what is the relationship between Host machine RAM and number of hyper V virtual machines?

what is the relationship between Host machine RAM and number of hyper V virtual machines?

 

Hyper-V, VM, Virtual Machine

You will have to ensure the Virtual Machine is running and connected to the Internet.

This means the physical host, the machine itself must be connected.

Review:

Configure Remote Desktop connection to Hyper-V Virtual Machine ...

 

Suspend and Resume VM much slower on HYPER-V than vmware

First, there are two ways to suspend a Hyper-V vm, Save (#1 in screenshot below) and Pause (#2):





Both can also be found in Action menu. Using PowerShell, the cmdlets are Save-VM "vm_name" (to resume Start-VM "vm_name") to save vm, and Suspend-VM "vm_name" (to resume Resume-VM "vm_name") to pause vm.

Difference between these two methods is that whereas Pause only releases all host processor resources still reserving RAM allocated to it, Save releases all host resources, including RAM. Pausing and resuming a vm is instant and the recommended way to suspend if your host has enough RAM to manage without part allocated to vm.

You could say that relation of these two suspend options is as relation of Sleep (Pause) and Hibernate (Save) on a physical machine.

Saving a vm really takes some time. This, the time needed of course depends on how much is going on, how many and how resource hungry processes are running on vm. Testing it just now on three virtual machines with different programs up and running I got Save times from 12 - 15 seconds (resume 5 to 10 seconds, no programs running) up to 25 - 30 seconds (resume 20 - 25 seconds, Windows Update installing updates, a document open in Word, a presentation in PowerShell, video playing in Kodi and so on). These times on low end i5 / 12 GB / 7200 spinner laptop host.

Not knowing Plex I can only guess that it might be at least a partial reason for your slow suspend. Why VMware does this faster, I have not a faintest clue. Sorry.



Tip Did you know that you can shut down / restart the host letting virtual machines to be up and running? I have selected Save the virtual machine state as Automatic Stop Action for all my virtual machines:





When I shut down the host, all my virtual machines running at that moment will be automatically saved. After restart they are not automatically resumed because I have selected Automatically start if it was running when the service stopped option in Automatic Start Options:



If I want a specific vm be run every time I sign in to Windows on host I would select Always start this vm automatically.
