Eu consegui instalar um Debian 7.3 como convidado no VirtualBox 4.3.6 VM com adições de convidados, e não sou capaz de fazer o trabalho webGL.
Embora eu possa ver o openGL funcionando (tentei com glxinfo e glxgears da linha de comando), não consigo fazer o trabalho webGL no Firefox / Chrome / Iceweasel (não tentei outros navegadores ). Para verificar se o webgl está ok, estou acostumado a navegar no link ; algumas notas informando o momento em que eu cheguei:
about:config firefox (e depois todas as informações relacionadas a previsões como true) Então, neste ponto: é possível fazer o webGL funcionar em um sistema operacional guest debian (ou geralmente em um sistema operacional convidado, porque talvez isso não seja suportado)? Acho que é mais simples a solução, menos personalizada e, portanto, menos sujeita a erros estranhos.
Aqui segue alguns links nos quais eu cheguei:
Tentei também com o convidado do Ubuntu 13.10, mesmo resultado.

Embora eu não tenha a configuração exata que você está usando, eu pude rodar o WebGL no firefox com o host rodando o Fedora 21, o VirtualBox versão 4.3.32 e o Fedora 22 como convidado. Eu também tentei o Centos 7 como convidado, com sucesso. Portanto, é possível executar o WebGL em um convidado usando o VirtualBox. Eu também tentei o Fedora 20 como o convidado com sucesso. Você pode querer visitar o site www.doesmybrowsersupportwebgl.com e ver o que ele diz.
