I did it on mine to test and it does work. All my VMs function normally again. This is temporary and will need to be undone after Oracle pushes out a new kernel module that fixes the issue.
For those who might not know how to do this at the command line, or feel uncomfortable doing it that way, I will show you in YAST.
Open “YAST”
In the System section, Open “Boot Loader”.
Click the “Kernel Parameter” tab of the window.
In the “Optional Kernel Command Line Parameters” box, paste in (make sure there is a space before it)
ibt=off
click “OK”
Reboot
