Hello

on both of the laptops i use - Dell 5410 with intel 11gen i7 and fully update and the Dell 7391 with intel 10gen fully updated. both experiencing the same issue where all my VMs on Virtual box wont load and stuck during the boot process - not sure which update caused and i think its a CPU problem

i tired rolling back graphics drivers on my UHD graphics and but no luck still the same issue

i think the cause might be a one of the recent updates... i did recently update my VM box to the newer version that rolled out...

i attached picture from my kali linux VM this error is both on the 5410 and 7391 "bug: soft lockup: CPU STACK
On win 10 VMS are they running super slow wont load most of the times.. i did get once the NO IRQL blue screen
and my flare vm is blury

i did try all combos when it comes to VM box settings

Please check if your VMs have 2 processors. If not, give them 2.

If that doesn't work, pick one failing VM. Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

somtimes this error will show up

and here is the most recent log. sorry for not adding it in the beginning

kali log.zip (156K) deleted by mod.

That log has not been zipped as requested, it's a text that has been renamed to have the wrong extension.

Plus I don't see any problem reported by the VM. This argues that it's the guest OS which hasn't been installed properly.

@OXB,

Your log does contain the telltale:
which indicates Hyper-V is active. You may want to try testing by disabling Hyper-V as there is a known 'conflict' with VirtualBox 6.1.34, as has been described past responses to some of your previous threads.

The latest VirtualBox Test Build may also provide a possible solution if you really need Hyper-V to be active, but installation of Test Builds requires UEFI Secure Boot to be disabled. If you go that route, please make sure you keep the downloaded Test Build installation files until the next full official release (6.1.36) is released and successfully installed in case the Test Build needs to be uninstalled. See: https://www.virtualbox.org/wiki/Testbuilds

Ah, I was distracted by the difficulty in viewing the attachment (because it wasn't really a zip as it claimed to be). So the VM hasn't hung, it's just slow because Hyper-v is enabled.

i was trying to disable Hyper-V using a few methods

power shell, cmd wouldn't confirm anything after running the commands

in "windows features" no record of Hyper-v

with the "Services" app - cant find Hyper-V Machine Management" option so i cant really tell whats going on

using "findstr" command - VScompute service is off

using task manager i can see that virtualization is enabled but nothing mentions hyper-v/////

its probably not working but it also seems it doesn't exist which is weird ...

Please see HMR3Init: Attempting fall back to NEM (Hyper-V is active).
