OT - Virtualbox x86 & x64 2.1.0 released Carlos 12/18/2008 5:16:01 PM Sun has released a new version of its freeware virtualization program Virtualbox (www.virtualbox.org). As of v2.0 it supports x64 guests and there is also USB 2.0 support. The interesting item in this new release is that it also supports x64 guests in 32-bit hosts, provided you have a 64-bit microprocessor. Yes, you read it right. You may be running XP 32-bit and have Vista x64 running inside a virtual machine! There is also experimental 3D support via Open-GL. Carlos

I ask because in previous Vbox versions running 64b guest on 64b OS on CPU without HW virtualization was not possible. -- Poutnik

Re: OT - Virtualbox x86 & x64 2.1.0 released Carlos 12/21/2008 3:53:00 PM Hi, I am not an expert in Virtualbox but I think the answer to your question is yes.

Re: OT - Virtualbox x86 & x64 2.1.0 released Poutnik <poutnikletspamisoutofabox[ at ]atlas.cz> 12/21/2008 5:15:20 PM I am afraid the answer is NO. Trying to Instal Linux Mandriva Free 2009 - 64 on Vbox64b 2.1.0 running on vista64 home Premium with C2D e4600 CPU results in Mandriva setup error msg: Wrong architecture: This is a 32-bit computer. You cannot use 64-bit software on it Msg is the same I got on VBox 2.0.x Serie C2D E4x00 does not have HW virtualization support, that was said requested to run 64bit guests in previous VBox versions. C2D E6x00 has - it should run in it.

Re: OT - Virtualbox x86 & x64 2.1.0 released Bobby Johnson <rjohnson[ at ]aol.NOSPAM.com> 12/21/2008 5:53:00 PM Download the user manual and read it. It will answer your question. Your CPU must be one that has hardware virtualization built into it 1.6 64-bit guests Starting with Version 2.0, VirtualBox also supports 64-bit guest operating systems. Starting with Version 2.1, you can even run 64-bit guests on a 32-bit host operating system, so long as you have sufficient hardware. In detail, 64-bit guests are supported under the following conditions: 1. You need a 64-bit processor with hardware virtualization support (see chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10). 2. You must enable hardware virtualization for the particular VM for which you want 64-bit support; software virtualization is not supported for 64-bit VMs. Note: On most systems, the hardware virtualization features first need to be enabled in the BIOS before VirtualBox can use them. 3. If you want to use 64-bit guest support on a 32-bit host operating system, you must also select a 64-bit operating system for the particular VM. Since supporting 64 bits on 32-bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request. On 64-bit hosts, 64-bit guest support is always enabled, so you can simply install a 64-bit operating system in the guest. Warning: On any host, you should enable the I/O APIC for virtual machines that you intend to use in 64-bit mode. This is especially true for 64-bit Windows VMs. See chapter 3.7.1.2, “Advanced” tab, page 46. In addition, for 64-bit Windows guests, you should make sure that the VM uses the Intel networking device, since there is no 64-bit driver support for the AMD PCnet card; see chapter 6.1, Virtual networking hardware, page 77. 5See chapter 13, Known issues, page 182. 6See chapter 13, Known issues, page 182.

Re: OT - Virtualbox x86 & x64 2.1.0 released Carlos 12/21/2008 7:35:01 PM Error message is misleading ("This is a 32-bit computer"). Yours is running Vista x64 on top of a 64-bit microprocessor. Page 12 of the user manual clearly states that no hardware virtualization is necessary.
