Guest Win7 is not starting, it just hangs

Post by YogiYang »

Hello,

I am using Win10 Home Version 20H2 and VB 6.1

My Win7 based VM was working just great but I just tried it today and it is not loading.

There are not errors generated. It just hangs.

I am attaching the log file here.

I have got 5 VMs with Win7 64bit as guest. None of these are working.

How to solve this problem?

TIA

You have these two lines in your log.

00:00:04.733660 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:04.830147 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might

Something has caused the Windows hypervisor to load on the host. See this post.

Hello,

Thanks for the info. I have recently installed Dockers. Does this interfere with VirtualBox?

if yes then how to circumvent this problem and deep both VirtualBox as well as Dockers?

If Docker invokes Hyper-V, then Docker will interfere with Virtualbox.

For now it's either-or. The linked tutorial has another link to a tenforums post that shows a boot-time switch to turn Hyper-V on or off. The devs are working on both at the same time. No time frame yet.

Hello

Thanks everyone for your help.

Finally it is solved. I removed Docker from my system and everything is working as expected.
