Cannot open VM after moving to new laptop

[JRS]

I zipped up the VHD and VBOX files and moved to a new laptop. The old laptop was running Win8, the new laptop runs Win7. The VM is Win7.

After unzipping, I added the machine to VirtualBox. That worked great, and the machine seemed to be installed ok.

When starting it, I see a window open, but before any Windows startup I get a dialog showing this error:

Failed to open a session for the virtual machine Windows7 Clone.
VT-x features locked or unavailable in MSR.
(VERR_VMX_MSR_LOCKED_OR_DISABLED).

The log includes this at the bottom:

00:00:01.164373 VMSetError: D:\tinderbox\win-4.2\src\VBox\VMM\VMMR3\VM.cpp(373) int __cdecl VMR3Create(unsigned int,const struct VMM2USERMETHODS *,void (__cdecl *)(struct VM *,void *,int,const char *,unsigned int,const char *,const char *,char *),void *,int (__cdecl *)(struct VM *,void *),void *,struct VM **); rc=VERR_VMX_MSR_LOCKED_OR_DISABLED

Let me know if you have any ideas how to fix this. Thanks.

Enable hardware virtualization in the PC bios.
