There may be some limitations (SMP and OpenGL) but my working 64 bit Guest suggests that it does work. Just recently I did a fresh install of windows 8.1 Pro and reinstall all of my apps including Virtualbox but now when im trying to reinstall Windows 7 Pro 64 bit on Virtualbox I get this message (Attempting to load a 64-bit application, however this cpu is not compatible with 64-bit mode. ? OpenGL host support is not yet available on 64-bit kernels ( Mac OS X after save/restore state or a resize of the Oracle VM VirtualBox Base Packages - 7.0. ? There are several redraw problems with compiz enabled window man- agers on Linux guests. ? OpenGL windows aren’t updated in the Dock Icon real time preview. Additional we are aware of the following issues: The system pauses before the virtual instance is formatted and I cant proceed. Im encountering the same message when I attempt to install Windows 2003 x32 in a Virtualbox environment at 2GB Ram or 3GB ram. This counts especially in combination with compiz enabled window managers. My host system is Windows 7 64-bit with 6GB physical memory. In general the OpenGL support for Linux guest is experimental. – The CPU frequency metric is not supported. – The numlock emulation has not yet been implemented. The following restrictions apply (all of which will be resolved in future versions): We copied the ova file to another machine (I7, 16Gb RAM, Window7 64 bit). 64-bit guests on 32-bit hosts do not support SMP yet ( except on Mac OS X). I installed Ubuntu 64 bit on my laptop (2Gb RAM) and exported to an appliance.In the 3.0.12 manual under Known Limitations there are 3 references to Mac OS X. Step 2: Run the Oracle VM virtualization software and click the New button from the menu or shortcut tools to launch the VM creation wizard. This is not a problem it just means I can only run up to a few of them at a time.Sasquatch wrote: I believe that 64 bit Guests on Mac are listed there as not working. Step 1: First, download the Windows 7 SP1 圆4 operating system from this link or a source online. For example, I have about 10 virtual machines, most of which have 1 GB of RAM, on a host machine with 4 GB of RAM. When the virtual machine is turned off, suspended, hibernated, or otherwise not running, this RAM will not be in use. It would not work out well to have two VM's with that amount of RAM!įinally, your virtual machine will typically reserve all the RAM you give it, whenever it is running. If you plan to run multiple virtual machines, then giving a virtual machine 2.7 GB of RAM out of a total of 6 GB is probably too much. At random times the guest OS dies in the VM, going to black screen. I created the VM with 2 CPUs and 2GB RAM, VT-x and Nested Paging are ON, ACPI and IO APIC are ON. This is a new VM with Win 7 32-bit, no anti-vir. I give most of my virtual machines, including Ubuntu virtual machines, 1 GB of RAM, even when I have enough physical RAM available that I could allocate more. I am seeing a crash with VB 3.0.8 that I have never seen before. When I got back, the Windows out-of-memory routine was running, and I had to shut down the guest. Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to). However, depending on what you plan to do with your Ubuntu system, it probably doesn't need 2.7 GB of RAM. Host: Win 7 64-bit, 8GB ram Guest: Win 7 64-bit, 2GB ram I left the guest running unattended for a while. We need to see a complete VBox.log, from a complete VM run, where the problem occurs. If you're running a single virtual machine, the suggestion you read is OK (provided that your host machine has enough RAM, which it does). You should give virtual machine however much RAM you need for the tasks you're using it to perform.
