Solved Hyper-V messed up. Lost Virtual Machine. :"(
-
This is totally and 100% user error. I did what I should not have done, delete the virtual machine file w/o making backup. Please don't ask why...
Right now All I have left is .vhdx and AVHDX files. I lost my snapshots and other xml files.What should I do? Can I restore a virtual machine with only VHDX and AVHDX files?
Suck for this to happen on Friday.
-
Yes, you can simply build a new VM with the same specs and attache the existing VHDX.
Should boot right up.
-
XML should just be metadata. Snapshots aren't necessary for anything. Having your actual disks should be all that you need. How big are the files? No corruption?
-
@JaredBusch So create a new virtual machine with different name and use the same vhdx file? I'll give it a shot.
@scottalanmiller The files are 10gb vhdx and 7gb avhdx. Not sure about curruption. Have to test it out.

This post is deleted! -
The avhdx is created after you take the snapshot. The vhdx is the original file. You May need to merge them for this to work. Use Hyper-V manager to inspect the disks so you know which is the parent image.
Make copies of everything before you try to create a new VM!

I just post something but then deleted the post just when Thedalton replied. Yeah.. it restore the original one, not the latest one. When I try the avhdx file it seem checkpoint is broken.
After inspect the Avhdx, it prompt me to reconnect but failed due to ID mismatch. I just click to ignore ID mismatch... is that okay?
-
If you made backups of these two vhdx I would try merging the two into one. Test and verify that all your data is there.

It is domain controller. I don't remember what I did to it last time. But so far so good.
But somehow I cannot run it off Gen2. I have to create Gen1 to run it. -

That is not really a big concern. There are no major differences in Gen1 vs Gen2 that will affect a basic VM.

Thank you all
Back to normal now. -

Also, Gen2 only works for Win Server 2012 and Win10 VMs...

False. All of my CentOS 7 VM's are Gen2

OK fine.. Specifically Windows VMs. We went through this with windows server when I was installing one a few weeks ago.
I think basically if the system can't use UEFI, it can't be a Gen2 VM.

Yes, that is the restriction I believe.

Gen1 allows legacy hardware such as a NIC for PXE boot. I believe Gen1 is Bios Emulation and Gen2 is UEFI
