Which version of 7 are you running? I’m aware of issues with the vmtools and 2022. I’d look at the VMs themselves - if you’re using paravirtual driver that could be of issue - and it’s not easy to fix. Update to the latest 7 vsphere, then your esxi hosts, then update the tools on the affected hosts in safe mode.

Another thing to check - if you can boot them into safe mode, its a virtual layer driver causing the hub bub.

This wouldn’t be a hardware level thing cause you’d get exceptions or callbacks from vmware before the OS gets a chance to load and BSOD. Hope this helps.

Btw: where did you get your rack? I’d love that setup!

Check iDRAC or iLO on your servers. They are able to pick up memory and cpu errors on the VMs.

You wouldnt happen to have energy saving features enabled would you?

Do you have EVC mode on for your cluster? Your hosts look like they could be pretty different. Is it possible your VM boots up or migrates to the other host with a much different CPU?

Where did you source the ISO’s from.

I realize you’ve tried and used multiple ones. I’m just curious, because I’ve ran both 7 and 8 clusters and I have never seen this issue except on poorly sourced or broken images.

did you try the install with nothing but bare minimum? So no nics, only one hdd presented to the guest (just for the c drive), usb 2 only.

Nothing different about the iso, so nothing slipstreamed in?

If you clone one of the working machines, then do a sys prep on it (so treats it like a new install) does this work?

I’m going to be offline for a few days, so may not respond right away.

Any storage connection issues? I’m running iSCSI on a synology without any issues.

BSOD error code?

Maybe try older Windows 10 builds and see if that makes a difference. Or even older windows versions
