Comment (by adrelanos):

 Will provide soon.

 Updated, full list of settings tried to fix this.

 {{{
 VBoxManage modifyvm vm-name --ibpb-on-vm-entry on
 VBoxManage modifyvm vm-name --ibpb-on-vm-exit on
 VBoxManage modifyvm vm-name --l1d-flush-on-vm-entry on
 VBoxManage modifyvm vm-name --l1d-flush-on-sched on
 VBoxManage modifyvm vm-name --spec-ctrl on
 VBoxManage modifyvm vm-name --nestedpaging off
 }}}

 (sudo spectre-meltdown-checker --paranoid ; echo $? still exists non-zero
 and shows "vulnerable".)
