That's not what I'm asking about.

I'm saying it takes a long time for it to even execute a single instruction, in the BIOS itself. Even for the window to pop up, before you can even pause the VM (because it hasn't even started yet). What you're describing comes after all that, which I already understand and am not asking about.

Unsubstantiated hunch: the hypervisor is doing a shitload of probes against the host system before allocating/configuring virtual hardware devices/behaviors. Since the host's hardware/driver/kernel situation can change between hypervisor invocations, it might have to re-answer a ton of questions about the host environment in order to provide things like "the VM/host USB bridge uses so-and-so optimized host kernel/driver functionality to speed up accesses to a VM-attached USB device". Between running such checks for all behaviors the VM needs, and the possibility that wasteful checks (e.g. for rare VM behaviors or virtual hardware that's not in use) are also performed, that could take some time.

On the other hand, it could just as easily be something simple, like setting up hugepages or checksumming virtual hard disk image files.

Both are total guesses, though. Could be anything!

I have always wondered the same, never tried looking into it but I wouldn't be surprised if Defender at least played a part in it. Defender is a huge source for general slowness on Windows from my experience.

probably the intel ME setting up for virtualization in a way that it can infiltrate

Please tell me you are joking. Even if it’s a lie.

Management Engine .. actually I do not have the energy to deal with paranoid people. I never had that kind of energy. I never will. You’re all so efficient at drawing energy out of conversations and killing them. You’re like conversational vampires. It’s exhausting.

I don’t even care if you’re right or wrong about Intel ME. It is just so exhausting listening to you guys because of your word choices. It’s like you try to get ignored.

I respect your opinion and all, you just need to work on your messaging or something.

"ME can also control various aspects of the Virtualization Engine directly over the ME Command Interface (MECI)."

Yeah ME is literally for managing things like UEFI settings remotely. That’s what it was designed for.

Ah yes, the source of all slowness in the CPU: hostile backdoors taking their time to compromise the work. Classic...
