Virtualbox Guest memory limitation with 64bit guest on 32bit host?

    I use Ubuntu 10.10 (32bit) as the host operating system. However I have enabled PAE so I can see the full 8GB of memory installed on my machine.

    I use VirtualBox 4.1.8 to create virtual machines which generally works well. I even use 64bit guests without issue. However I'm limited to 3584MB of memory for the guest operating system. I would like to increase this somehow.

    Is this the result of the 32bit host? Is there anyway to overcome this? Will I still be limited if I change to a 64bit host? Thanks.

    I guess you need a 64bit host system to use more than 3584 MB memory for virtual machines.

    64 bit - Can VMWare Workstation 7.x and Sun VirtualBox 3.1.x co-exist on the same Windows 7 64bit Host together?

    Will installing Sun Virtual Box bash or interfere with my VMWare installtion?

    I don't need to run VMs from both Virtual-Machine software packages at the same time but I do need to run some older Virtual-Machines from Sun-Virtualbox on the same 64-bit Windows 7 host until I can migrate those VMs to VMWare.

    Before switching from Linux host to Windows host, I ensured to export the VirtualBox VM to an OVF "appliance" with intentions of importing into VMWare Workstation 7. But VMWare gives me an error stating it can't import it.

    I need to get my original Sun-VBox Windows-XP Guest running on my new Windows 7 Workstation either imported into VMWare or running on the Windows version of Sun-Virtual box (I have the VM-Guest Backed up and copied to the new computer data drive.

    Yes, I currently run both VMWare Workstation 7 and VirtualBox (3.1.6 ISTR) on the same Windows 7 64 bit host. They co-exist without problems.

    With respect to problems importing the appliance into VMWare, I'm about to do the same. During my research, I came across the following page, which might help here: http://blogs.techrepublic.com.com/window-on-windows/?p=2997. Didn't try it yet, though.
