Googling 'Debian Wheezy 64 bit memory limitation' only turn up references to Squeezy and the Debian Handbook doesn't seem to address the issue. I would greatly appreciate being pointed to any sources of information about this issue. Just a quick check, have you told VirtualBox that you'd like the guest to be 64-bit? When creating a VM, you typically tell VirtualBox what kind of OS will be installed. For Debian, there will be TWO entries: Debian and Debian (64 bit). The first will HIDE your CPU's 64-bit capabilities from the Guest OS (Wheezy). signature.asc Description: Digital signature

Are you running Wheezy _inside_ VirtualBox with Windows 7 as the host OS, or is this a dual-boot system? If the latter, wheezy should easily detect 8 GB and use them. In case of the former, you probably only allocated 4.7 GB to Wheezy in the VirtualBox configuration, hence the ‘computer’ Wheezy runs on only has 4.7 GB.

In this case that' appears to be 4.5 to 5GB. Reading the VirtualBox documentation will very likely answer all of your questions relating to this. The problem is almost certainly not with Debian. There's probably a menu box somewhere that allows you to configure the amount of memory for the virtual machine. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
