Dear Qemu & KVM Developers,

1) the praise: thanks for kvm-qemu,

first off the praise:

• kvm-qemu is a high performance nicely scriptable virtualization system
• checkout this hd bench https://dwaves.de/wp-content/uploads/2021/09/windows-7-32Bit-virtio-drivers-kvm-qemu-crystal-disk-mark-benchmark-Screenshot-at-2021-09.jpg
  
• if it works, it can do pretty things 🙂
• especially like the x11 forwarded virt-manager gui over ssh (yes it is a bit slow… but simplicity at it’s best)
• https://dwaves.de/wp-content/uploads/2021/09/virt-manager_2021.jpg

2) the problem/the critique:

• why is thin provisioning not the disk-saving default option?
• or at least should be possible for the user to select this option in virt-manager

• do not drop windows 7 support just yet… many virtualization systems such as VirtualBox are actually intended to run “outdated” OS on newer hardware for the sake of getting programs to run, that are incompatible with recent OS.

something is very wrong with the default settings for windows 7 64bit ultimate: it is stuck at 0% during setup (as if the harddisk died)

(this was tested and found valid on two different systems using GNU Linux Debian 10 and 11)

the only workaround that worked so far: go with 32Bit and use virtio as disk driver system :)

help! :)

& best regards
