Virtualbox on Kubuntu 15.10 - Failed to open a session for the virtual machine

I recently upgrade to Kubuntu 15.04 to 15.10 yesterday. And after the upgrade, I installed VirtualBox, and I created the virtual machine "Windows XP". I configured this virtual machine and I started this virtual machine and it failed to boot. I have these error messages:

How can I solve this problem?
