Solved HP Administrator Tools disabled when trying to enable hardware virtualization for Windows phone emulator.

Got this message when trying to run the windows phone emulator on my new computer an hp folio 9470m:

Clicking on "More information" and you end up on this MSDN article: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj863509(v=vs.105).aspx

Following the instruction I tried to log in as administrator in the BIOS but all Administrator Tools settings were disabled, could not find out why, the log in seemed to be ok with the credentials.

After searching the hp support forum I finally gave up and started to googling the problem, right a way I found this post on the hp support forum http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/All-BIOS-options-are-disabled-grayed-out/td-p/2169837,

You have to log in as guest and set the BIOS administrator password to get the Administrator Tools enabled, really bad UX, why not prompt the user to set the administrator password the first time?

Error: Loading plugin error: Cannot load library /usr/local/SomeLib/libSomeLib.so.1.0.0: (/usr/local/SomeLib/libSomeLib.so.1.0.0: undefined symbol: _ZN18SomePluginModuleD1Ev)

Got this annoying error in QPluginLoader when I deployed and tried to run the application. It took a while before i realized what my mistake was.

I accidentally missed to add a implementation for the destructor and that caused the error message, found this forum post that got me in the right direction:

.h with destructor:
~SomePluginModule();

.cpp did not have:
SomePluginModule::~SomePluginModule()
{
   //clean up...
}
