Hi, not sure if this is the place for this, but I've found a little confusing to find where to mention a debian-wiki issue...
The SystemVirtualization[1] wiki-page offers as first 'Debian solution' VirtualBox[2], which is non-free and "not available in Debian 10 and won't be in buster-backports either[3]. A recommended alternative is Virtual Machine Manager (buster/virt-manager)", so, I suppose virt-manager[4] should be the first offered Debian-solution, wouldn't be? Best regards!
