Por algum motivo, não consigo descobrir (como ajustei minhas configurações de VM para tentar fazer com que esse erro desaparecesse, sem sucesso). As VMs do Windows 7 e 10 não estão iniciando o erro:
Failed to open a session for the virtual machine Windows <NO>.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}
onde <NO> é 7 para o Win7 e 10 para o Win10. Apesar disso, minhas VMs BSD, FreeDOS, Linux, Icaros, OpenIndiana e ReactOS estão começando bem. Eu tentei seguir esta resposta em Ask Ubuntu tão perto quanto eu posso (como eu acho que o VirtualBox mudou usando xml arquivos para usar vbox arquivos para armazenar as configurações) link . Em outras palavras, removi meus arquivos .vbox para o Windows 7 e 10 VMs e movi .vbox-prev para .vbox . Eu também tentei reiniciar após a atualização do VirtualBox 5.1.18 para 5.1.20. Se for relevante, meu sistema operacional host é o Gentoo Linux.
Aqui está o meu arquivo .vbox para o Windows 10, se for relevante:
<?xml version="1.0"?>

Acontece que este é um bug que desclassifica para o 5.1.18 corrigindo o erro perfeitamente. Eu relatei esse bug no link do Gentoo Bugzilla.
EDIT: A partir da linha de comando deu uma saída não mais detalhada. Nomeadamente começando com:
VBoxManage startvm "Windows 10" --type headless
falha com o erro:
Waiting for VM "Windows 10" to power on...
VBoxManage: error: The VM session was aborted
