Hi Christian, Ok, understood. And, yes, you are correct: basically I create a qcow image file and then: - Bering works fine when passing qemu the qcow image file to be used as the HDD - Bering doesn't work when mounting the same qcow image file and then launching qemu to access those same files

Hi Rolando, there are further changes in this build - we need to exclude that you are seeing this just due to only downloading the .deb file instead of enabling proposed to gain all required dependencies. You can instead of an full "apt upgrade" also run rather selective upgrades. I'd recommend

Hi, I haven't touched on anything that would bring much more features to the vvfat code. In general it is a helper to sync data, but it is brittle I'd not even so much like to see a bootsector support there. That I don't find anything doesn't mean there is nothing, if you know an upstream commit

Gah obviously for vvfat it isn't an image to be created at all. So I thought steps to reproduce are: 1. get a guest that works (via uvtoools-libvirt or whatever you prever) 2. get the qemu commandline that it is started with, in my case: $ sudo kvm -m 1024 -drive file=/dev/sdb,format=raw,cache
