not sure if passed, but there could be the possibilty to add the hyperv extensios to the -cpu call that often seem to help: https://www.qemu.org/docs/master/system/i386/hyperv.html

try something like:

     environment:
       VERSION: "win11"
       ARGUMENTS: "-cpu host,hv_relaxed,hv_vpindex,hv_time"

@abbbi Hyper-V extensions are already enabled by default. You can see the flags that are passed by setting:

     environment:
       DEBUG: "Y"

so the only thing worth trying might be to disable Hyper-V, which can be done like this:

     environment:
       HV: "N"
