VirtualBox is very slow in Windows 10 - green turtle icon exists

[dardar]

Hi all

I'm running Virtualbox on Windows 10 Pro (version 20H2) and the guest os I'm running also Windows 10 Enterprise .
my laptop hardware: intel core i7 1165G7 with 16GB of ram

my virtual box version is 6.1.26 + installed extension
VM settings: I'm giving it 4096 MB with 2 processors
I tried 1-4 processors with different ram allocations. also tried to enable 3D Acceleration

things I did:
I uninstalled docker desktop (since it is using hyper-v)
I enabled and disabled hyper-v in windows (in bios it's enabled) - not sure if this should be enabled or not tbh
the power mode is "performance" for my laptop

when I start the VM it's soooo slow. sometimes I can login and sometimes not. but after the login everything is very slow.
I read that the green turtle indicates that there is a performance issue but not sure how to handle it

any help would be appreciated

The log contains this text:

Attempting fall back to NEM

which means Hyper-V is still enabled. The turtle is also an indicator. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

hyper-v in windows (in bios it's enabled)

Unless Microsoft got BIOS makers to start calling BIOS settings "Hyper-V", you're probably talking about "virtualization technology" (VT-x/AMD-V/SVM) which is used by both Hyper-V and Virtualbox to make VMs run faster. (Hyper-V and Virtualbox can't use VT-x/AMD-V/SVM at the same time, though, and Hyper-V gets first dibs because it loads first.)

Thanks a lot for the quick reply.

hyper-v was indeed enabled when I saved the log.
I just turned it off (added a screenshot as an attachment), restarted my host, and started the VM again.
unfortunately, the slowness is still a problem
I'm attaching a new log file

thanks

I'll let you keep cranking away at it. The solution is there, just not where you went. In fact, once you do find the solution you'll see that going where you went is specifically not recommended.

hi

I read again the post you mentioned before and it did fix my issue

but ' something is bothering me now.
in order to fix this issue, I had to uninstall docker desktop and turn off hyper-v

does that mean that I can work with VirtualBox and docker abilities on my laptop?

On your PC, Hyper-V-based services/apps and full-speed Virtualbox can't run together yet. Getting Virtualbox to work well under Hyper-V is an ongoing project. There is a possible either-or boot-switch mentioned.
