Updated to Virtualbox4.3.6 & Phpvirtualbox4.3.1 ->
Can't even display Console in phpvirtualbox ('console' button is greyed out).
Can't define remote display port in machine configuration.
Remote Desktop is well checked in Configuration.
Remote display tab in Display is greyed out.

Thanks in advance for your help.

Well, sorry , it isn't at all phpvirtualbox related.

virtualbox extension pack wasn't updated.

Here is how to update it:
list actual extpacks:
vboxmanage list extpacks
->
Extension Packs: 1
Pack no. 0: Oracle VM VirtualBox Extension Pack
Version: 4.2.18
Revision: 88780
Edition:
Description: USB 2.0 Host Controller, VirtualBox RDP, PXE ROM with E1000 support.
VRDE Module: VBoxVRDP
Usable: false
Why unusable: VBoxExtPackRegister returned VERR_VERSION_MISMATCH, pReg=0000000000000000 ErrInfo='VirtualBox version mismatch - expected 4.2 got 4.3'

Download the extpack from VB:
cd /tmp
wget http://download.virtualbox.org/virtualbox/4.3.6/Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack

As ROOT (sudo won't do it on Debian-like distros)
sudo su -
VBoxManage extpack uninstall "Oracle VM VirtualBox Extension Pack"

Install the new extpack:
vboxmanage extpack install /tmp/Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack

Hope this will help some.

I did that, but I found I had to stop and restart the kernel module before it would "take". (VBoxManage list extpacks showed the correct version as root, but the old version as the vbox user. Had to /etc/init.d/vboxdrv stop and /etc/init.d/vboxdrv start before the vbox user would show the correct extension pack version.)
