error: VERR_VMX_MSR_ALL_VMX_DISABLED when starting Pega Marketing Enablement 7.1
Error: starting the lesson, the vbox throws an error
VT -x disabled in the BIOS for all CPU modes
VERR_VMX_MSR_ALL_VMX_DISABLED
Solution: This message is a red herring. The solution (from stackoverflow) is to change the memory allocation. The default setting was 4096. I changed it to 2048 and it is working fine now.
