Could not connect to host


Post by Jyjon »

I get the error:

Could not connect to host (

clicking the 'Detail' button gives this information.

Exception Object
[message:protected] => Could not connect to host (
[string:Exception:private] =>
[code:protected] => 64
[file:protected] => /usr/local/www/phpvirtualbox/lib/ajax.php
[line:protected] => 123
[trace:Exception:private] => Array

[previous:Exception:private] =>

The console gives the message:

vboxdrv: fAsync=0 offmin=0x5d0 offMax=0xfd8

I can't connect with either link on the GUI tab.

Any working solution would be appreciated.

If this is not first time to use vbox, check permission.

upgraded to but cant access virtualbox:

Also if you use full version instead of embedded, check /tmp/.vbox-vboxusers-ipc.
At this time, full is not supported, no longer tested recent services such as samba AD, vbox, syncthing etc.
