Php HHVM FastCGI配置问题-ProxyPass失败

我在Ubuntu12.04上，在Vagrant上运行。Apache 2.2.22

我一直在尝试在hhvm上测试我的应用程序。我按照以下方式配置了所有内容：

在vhost配置中添加fastcgi模块部分后，我开始出现404未找到错误。然后我发现我需要使用ProxyPassMatch。在添加ProxyPassMatch行之后，我开始得到500个内部错误。我的apache日志显示：

[warn] proxy: No protocol handler was valid for the URL /index.php. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

所有模块均已启用

这是我的vhost配置：

ServerAdmin webmaster@localhost
DocumentRoot /opt/myapp/www/
ServerName myapp.demo
ServerAlias myapp.demo

ErrorLog  /var/log/apache2/myapp.demo-error_log
CustomLog /var/log/apache2/myapp.demo-access_log common
