CentOS Stream Can't Run

[BenyaminL]

Hello. I've problem with VBOX 6.1.8.
I already seen through (I have a 64bit host, but can't install 64bit guests)viewtopic.php?f=1&t=62339, but no luck.

I tried to run CentOS Stream 8, and I already set the system acceleration to HyperV, it can boot into installation selection, but after press install, it will blinking forever.
Maybe there're some hints that I could do. Thank you

I attach the log with this post, hope there're some hint. Thank you.

That's all we got, there ain't no mo'.

I already set the system acceleration to HyperV

'Tain't the right direction for the time being.

At the risk of suggesting to go over old ground, but to go over it more carefully:

Your log contains these lines:

{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

You might notice in the guest window's Status Bar the green turtle: The choice of animal is appropriate: Your guest is running, just really slow. Or it might guru-meditate. This is because a service that uses Microsoft Hyper-V is running on your host PC. Normally Hyper-V blocks Virtualbox. But your PC is of the type and OS where Virtualbox can attempt to run the guest using the Hyper-V engine. This arrangement is still being developed and isn't 100% yet.

If VirtualBox is running without Hyper-V enabled, and nothing else is interfering with hardware virtualization (VT-x / AMD-V), then the usual virtualization icon () will be seen in the Status Bar.

To turn Hyper-V off completely, do this:

1. Shut down all programs. You will have to reboot your host.

2. See I have a 64bit host, but can't install 64bit guests. This tutorial has a couple more things to look for in step 2. Be sure these are all turned off.

3. Find the Command Prompt icon, right click it and choose Run As Administrator.

4. Enter this command:

bcdedit /set hypervisorlaunchtype off

5. Enter this command:

shutdown -s -t 2

6. When the computer turns off, unplug it for 20 seconds. Then plug it in again and boot up Windows 10.

If your Virtualbox does not start successfully, zip and post another vbox.log. For further info, see https://www.tenforums.com/tutorials/139 ... puter.html

Any thank you sir. I seen you merge the problem on the viewtopic.php?f=6&t=90853&start=270(VirtualBox 6.0 and Hyper-V)

Sorry for not reading fully there. Seems I turn it all on. Hahha.. -_-

I will come back here again once more. Thank you. Hope there will be some changes. Thank you

EDIT :
It's working now, but the NAT connection seems disappear from windows network. How to recreate it? It only have Virtualbox Host only network. Thank you

Ah never mind, it's centos issue. sad.
Anyway my old laptop feel snappy when the Hyper-V turned off. Grrrr microsoft. Thaks you @socrates
