I have experienced alot of errors in K2BP recently while developing on a MS 2007 VPC. After hours of debugging and attempts to find the cause of the problem, it came to light that my VPC Options did list the "Enable hardware virtualization" option, but it was not enabled to be selected.
When the exact same VPC and all its content was connected to and started with a PC that did support and enable VPC Hardware Virtual, all seem to be fine. I will be conducting further testing, but just very peculiar.
Please take not of this scenario, since it was very frustrating and time cosuming to finally pin point the problem.
