VERR_PDM_DRVINS_UNKNOWN_CFG_VALUES
Reinstalled VirtualBox when 2.1.2 came out that fixed an annoying display bug that had prevented the client from displaying the guest properly.
I had uninstalled 2.0 thinking it was an error in my installation that was causing the bug until I found a post on their forums about the bug. 2.1.2 just came out so I installed that and needed to reset my portforwarding rules that went along with NAT.
Using commands like the following I added ssh,http,mysql etc.
VBoxManage.exe setextradata "CentOS 5.2-2.1" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/Protocol" TCP
VBoxManage.exe setextradata "CentOS 5.2-2.1" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/GuestPort" 22
VBoxManage.exe setextradata "CentOS 5.2-2.1" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/Host" 2222
Of course I had a typo on one of the lines using "Host" instead of "HostPort".
This caused VERRPDMDRVINSUNKNOWNCFG_VALUES error dialog when I tried to start the VM.
To undo the mistake rerun the setextradata command but leave off the last value. So in my case :
VBoxManage.exe setextradata "CentOS 5.2-2.1" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/Host"
Then rerun the command using the proper syntax and the error should go away.
On a side note I really like Virtualbox compared to the new Tomcat based VMWare Server. Just seems to work better.
