I apologize upfront: I am very confident that this issue has been discussed and that the answer is already out there - but because of the mix of keywords, Google isn't helping much (97% of the results deal with installing Windows 11 in a VM, which isn't what I'm trying to do here). I thank you in advance for your patience.
Physical Host:
- 12th-Gen i7 system w/TPM 2.0 and 32GB RAM
- Secure boot is set to "relaxed" (allow 3rd-party signatures)
- Windows 11 Pro 22H2
I find that I must create my guest VMs with:
- UEFI
- encryption (only the files needed to support a TPM)
- TPM added to the hardware list
If I don't create my VMs with those pieces, I find that:
- I can only add to VMs a single CPU with a single core, or VMs won't boot (i.e., adding multiple CPUs and/or cores leads to unusable VMs).
- Once VMs are running with a single-core single-CPU, they are highly prone to crashing (i.e., even with a single-core single-CPU, VMs are largely unusable).
(Interestingly, I do not have to enable secure boot.)
I have confirmed the above behavior with guests running Windows 10, CentOS 7, Ubuntu 22.04 LTS, and Oracle Enterprise Linux 8.6; OS doesn't seem to matter.
Is this expected behavior? If not, how can I work around it?
