Yeah, been using websites for qemu-kvm and some help from a guy on siduction, but the bridging set up and converting the info from older web sites from old libraries prior to the gcc transition is a bit much. Converting to systemd-networking and the applying the bridge is a bit much also - even with just etho and no networkmanager has been no walk in the park. I will try for some help from HOAS, but - I deeply appreciate your input. I got the uefi up and lvm up and like both, thats enough learning, time to get machine into productio. Again, Thanks seonine!
EDIT: Following https://wiki.debian.org/VirtualBox#Desktop
"apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') virtualbox"
and I can say that it works in Testing. This box is not sparky (another one is) so in Sparky the vbox dkms is already in and ready to go - I believe.
My windows license key crapped out new hdd and mobo. I paid for a new key, but later see that using my XP cd and key might have gotten me up for free.
I will mark this as solved
