VB 4.3.12 Does not recognize 64 bit Win 7 Host

[smack815]

I have seen many issues like this and have read many of them but I still can't seem to get a resolution.

I am using Windows 7 Home Premium 64bit (build 7601 sp1) but can not select Ubuntu 64bit. I have searched the bios and there are no settings that I can set for this.

Your processor does not support hardware virtualization. You will only be able to run 32 bit guests and they will be slow.

My processor does support virtualization.
Why am I having this same issue?

VB 4.3.12 r93733
Host: Windows 7 Enterprise SP 1
64 bit OS
RAM: 3.90GB (usable)

Guest: I can't create a 64 bit Linux guest, only 32 bit options available (I'd like to create a 64 bit Red Hat, but any Linux would do)
When I create a new guest (or review Settings > General > Basic tab) the only options in the Versions field are (32bit) options (same as screen shot above).

I'm a complete noob. Is there a configuration step that I missed?

Well this is not helping as it does not show anything about the host. Post the guests log file ( as an attachment ) instead.

Intel Processor ID Utility says that Virtualization technology is supported, perhaps there is some other configuration I am missing?

[Perryg]

Code: Select all

WARNING! 64-bit guest type selected but the host CPU does NOT support HW virtualization.

According to VirtualBox the guest does not support hardware virtualization. This can be that something else has taken control of VT-x or your bios does not support it.
Until this is fixed however you will not be able to use 64-bit guests.

Make sure that you do not have hyper-v or xpmode installed on the host, and/or contact the host PC vendor to see about a bios update that allows VT-x.

Cool. Thanks.
