VMware Workstation unrecoverable error: (vcpu-0)

Hi. I wanted to boot up my MS-DOS virtual machine and this greeted me:

pastedImage_0.png

What happened here? What is VERIFY D:\build\bora-16894299\bora\vmcore\monitor\ulm\platform\windows\ulm.c:967? I do not have 😧 drive in my system, nor do I have any sort of source code it tries to verify? What's going on?

This is contents of the log file:

Oh, sorry, didn't see it (too small, didn't notice it is there - I was looking for it though, honestly).

Okay, here we go.

hahakiki2010,

Regardless MSDOS VM is supported or not in version 16.0, it looks like there is a problem of the ULM crashing with the Windows 10 insider preview.

This thread has

2020-10-28T10:52:03.615+01:00| vmx| I005: Host is Windows 10 Home, 64-bit (Build 20241.1005)

and other thread https://communities.vmware.com/message/2993299#2993299

2020-10-27T01:38:34.103-07:00| vmx| I005: Host is Windows 10 Pro, 64-bit (Build 20241.1005)

Both crashes on the same line of code

2020-10-27T01:38:42.942-07:00| vcpu-1| E001: PANIC: VERIFY D:\build\ob\bora-16894299\bora\vmcore\monitor\ulm\platform\windows\ulm.c:967

2020-10-28T10:52:06.740+01:00| vcpu-0| E001: PANIC: VERIFY D:\build\ob\bora-16894299\bora\vmcore\monitor\ulm\platform\windows\ulm.c:967

Eventually this insider preview will become Windows 10 21H1 (or whatever MSFT will call it); so this ULM crash should be looked into.

Thanks.

My MS-DOS machine works just fine under Workstation 16.0.  And it's the first production release with dariusd's fix for the CGA mode 6 in the video graphics adapter... so it darn well BETTER be supported!

So it is issue of Windows 10 Insider Preview? This is my Insider Preview build:

I'm having the same issue when trying to boot a Windows 10 guest using a Windows 10 Insider Preview (build 20246) host.

So it hasn't been addressed yet. I'll try out my Linux guest and if it fails to boot, too, due to the same error, then I guess we need to report it to Microsoft as well...

You might be better posting this on a Microsoft forum than here.

I did just that, waiting for a response therefore: VMware and Hyper-V compatibility - Microsoft Community

Let's see what Microsoft devs has to say about that...

So it has been addressed and fixed in build 20251, and I can confirm that it works in my current build 20251.1
