@LJ when you install the drivers into the VM's the hypervisor will be able to manage the RAM allocated to each VM. This way you can over-allocate (to a reasonable degree) and be pretty safe and not have to worry about not allowing enough RAM for Dom0.
If using Hyper-V and your VM is running modern Windows Server, you don't need to install any virtualization drivers.
That's good to know, but would you honestly skip the drivers?
They exist for a reason. .

I have 30GB on C:\ where the Hypervisor OS is installed and most of the rest on F:\ where the virtual disks for the VMs are. Is the 30 too small, too large, about right for Hyper-V OS?
If you have room, I'd set that a little larger. To allow for updates, or whatever.
On recommendations here at ML I have been using 80GB as my go-to, but that isn't set in stone.

@brrabill Thanks. I haven't got there yet but I assume there is a way to change the size of all the drives without starting over.

See this link, there is absolutely nothing you need to do inside a modern Windows VM:

@dustinb3403 Any reason you would prefer UrBackup over Altaro Free or Veeam free?

@lj said in Help with my first Hyper-V setup:
Do checkpoints recover all files or just OS files (kind of like System Restore in desktops)?
Checkpoints are snapshots of virtual machines. They are point-in-time snapshots of the VM and the VM's settings.
Useful for making a configuration change or installing an update (in the VM). If something fails, you restore the snapshot. Checkpoints should not linger around for more than a day or two. Use backups for backups.
-
@obsolesce Makes sense. Thanks.

I use Altaro VM Backup (Free Edition) and works great. Free edition allows up to 2 VM which you are currently using anyway. If you will need more, the standard is $515 per host for up to 5 VMs.

@black3dynamite I like it so far. I can't remember why I tried it instead of Veeam but to seems to work fine. I haven't tried a restore from it yet.

A bit more flexibility with open source software compared to free but closed source software is all.

Dude, don't make statements like this if you're not sure of what you are talking about!

https://www.altaro.com/vm-backup/pricing.phpDoes that include file-level restore?
And what do you do to get the backups offsite?

File-level restore is only available with Standard, Unlimited and Unlimited Plus.
You have a couple of options to have backups offsite.
Local backups can be copied to an Altaro Offsite Server over a WAN/Internet Connection. Or local backups can be copied to one or more rotating drives. -
Thanks for everyone for everything I've learned so far. Here is my next problem. I decided to expand my volume the Hyper-V OS is on. I was able to use Diskpart to shrink the other volume but was unable to extend the OS volume. They must not be adjacent but without Disk Management I don't have a visual. I tried booting Gparted and Partition Wizard mini tool. Neither would boot. They may be a few years old. How can I extend the volume?

You can use disk management remotely.
Open up
compmgmt.mscon Win10 computer, then right-click to connect to another computer. Connect to your Hyper-V host, then under Storage, select Disk Management.But yeah, if they aren't adjacent, you won't be able to extend, but you may be able to span or whatever if you convert it to a Dynamic disk... but if you dont' have any production VMs going, I'd start over.
Make your
partition like 65-85 GB, and for 
partition, use the rest of it for VM storage. -
@obsolesce That is the one thing I haven't been able to get working. computer management will allow some of the functions like users and groups but the disk management won't work and I've tried a lot of googled solutions. Most of them are Powershell commands to run on both machines. None of them have worked.
Starting over may be good experience anyway. I will backup my VMs with Altaro and also with Hyper-V manager if I figure out how. If I lose the VMs I still wouldn't be in too bad a shape. -
@lj The message when attempting Disk Management is "You do not have access rights to Logical Disk Manager on...

Is your Win10 computer and Hyper-v host joined to a MS AD domain?
-
@obsolesce The Win10 is and the HyperV host is not.

There's things you need to do like allow remote access to the Plug and Play interface, open up some firewall rules, allow remote server management through WinRM, automatic startup of Plug and Play service and Windows Remote Management (WS-Management) service, etc.
