Virtual Box 6.1 loading initial ramdisk

[rk_19]

Edition: Windows 10 Pro
RAM : 8 GB

Base memory: 3600 MB on virtual VM settings
Graphics controller: VMSVGA (if I select other than this, it shows this message "Invalid settings detected")

Whenever I start the VM, it boots very very slow but eventually it opens but it takes a lot of time to boot. Any specific setting I need to change, please direct me to it?

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

I didn't find the text.

Just a gentle reminder, any resolution to this issue?

Why did you disable System > Acceleration > Nested Paging?

@scottgus1: For your log message filter:

00:00:08.329961 [/HM/] (level 1)
00:00:08.329968   EnableNestedPaging <integer> = 0x0000000000000000 (0)

Thanks, at least little better than before.

If you're interested in further feedback, you should provide a new (zipped) VBox.log file.

And perhaps provide an explanation for the term "slow", because everyone interprets that differently.

FWIW, nested paging (EPT/SLAT) was a major breakthrough (in terms of speedups) in hardware virtualization more than ten years ago. When I disable it on my VMs, booting the Linux and Windows guest OS takes 10 times as long.
