I decided to give W11 a try as a VM on my Truenas. I gave the VM plenty of processor, ram, drive space etc. I loaded it and the virtio stuff. Then debloated it to as thin as I could and it is still DOG SLOW. I never really intended to use it and didn’t have a real need since I have other Doze boxes but just wanted to see. I will stick with NIX vm’s. After a few tweeks it works much much better
Better details?
I have been running several W10 VMs that are now upgraded to W11 and I cannot complain.
They VMs are a tiny bit faster than the same W11 on the same hardware.
Bottom line, they work as expected.
Something must be wrong with your config/setup.

2 processors, 4 cores, 2 threads. 8gb ram. Running on a dell630
That’s an old machine/CPU, but should run decent.
Don’t give the VMs, CPUs, only cores, (4 cores).
Running on SSD?
I imagine you installed all the virtio drivers?
What exactly is slow?
Added more cores and it is acceptable now. Still not as fast as a real machine but then it is a VM. Thanks for the recomendation.
My experience with TN CE and Windows 11 is way better than with e.g. Proxmox.
- Set the CPU type to “host”
- In Windows 11 disable core isolation memory integrity
It’s working great for me.
HTH,

Yes. Host passthrough is the best as KVM does not need to execute certain newer instructions in software, when the CPU does support them.
That is how I have it set
