Re: bhyve + swtpm + W11

Many thanks!

It also works in already installed windows 11.

I made a small change to the script so that I can run it in a common location for multiple VMs:

#!/bin/sh

VMNAME="$1"

SOCKET="/tmp/.bhyve.tpm.$VMNAME.sock"

if [ ! -S "$SOCKET" ]; then
nohup swtpm socket --tpmstate backend-uri=file:///vm/$VMNAME/tpm.state --server type=unixio,path="$SOCKET" --tpm2 --flags not-need-init &
fi

I think it works on Server 2022 and 2025 too, I'll do some testing


There's another major problem with Windows 11 and Server 2022/25: excessive host CPU usage. Has anyone found a solution?
