I already moved most of the code into a new PVE/QemuServer/Virtiofs.pm module.

Just an clarification & question concerning the queue-size:

There was problem with Windows Guests:

queue-size=1024 is still in every documentation and every qemu command for virtiofs I have seen used 1024.
Would it better to add a parameter to configure this queue-size?
