Can I upgrade my DV7-2173cl processor to one that supports virtualization (vt-x or vt-d). Processor is: 2.00 GHz Intel Centrino 2 Processor Technology featuring Intel Core2 Duo Processor P7350

Would be quite challenging. From cost perspective it may be good to get a new laptop rather than trying to upgrade. Also the n1000c is rather old and compaq or HP doesnt support it. So perhaps you can consider investing in a new laptop :)

Advantages of Server Virtualization

Hardware Virtualization uses software to create a Virtual Machine (VM) that emulates a physical computer. This creates a separate OS environment that is logically isolated from the host server. By providing multiple VMs at once, this approach allows several operating systems to run simultaneously on a single physical machine.

Rather than paying for many under-utilized server machines, each dedicated to a specific workload, server virtualization allows those workloads to be consolidated onto a smaller number of more fully-used machines.

Beginning with Windows Server 2008, server virtualization using Hyper-V technology has been an integral part of the operating system. Windows Server 2008 R2 introduces a new version of Hyper-V. Hyper-V makes it easier than ever to take advantage of the cost savings of virtualization through Windows Server 2008.

· Increased availability for virtualized data centers through enhancements such as Live Migration

· Improved management of virtualized data centers through Powershell and System Center integration

· Increased Performance and Hardware Support for Hyper-V Virtual Machines via 64 logical processor support and processor compatibility mode

· Improved Virtual Networking Performance through new networking technologies

· A simplified method for physical and virtual computer deployments by using .vhd files

· Designed to provide a secure computing platform across both physical and virtual environments, enabled through next-generation architecture and security features

In the middle of installing Windows 98 in Virtualbox I get a message Application Error SUWIN caused an Illegal Instruction in module VGA.DRV at 0001:011B. How can I fix this error?

Is this occuring during the install?

If this is the case, try this (it will be useful to know when the problem occurs):

Go to the VM Settings
Go to System
Go to Acceleration Tab
Uncheck Enable VT x AMD V

I hope that helps.

If not, there is a guide on the virtualbox forums here

Which I would suggest trying to run through instead.

I just finished installing Win 8 on a Compaq evo ultra slim after restarting I get error code 0x0000005d what can I do , is my motherboard not compatible its a pentium 4

Go to BIOS, find option 'Data Execution Prevention', and enable it. Moreover, enable option called 'Virtualization Technology (VT)' feature, in a case; you are trying to install Windows 8 from virtualization software like oracle or VMWare.

How to enable above option

To enter in BIOS, restart computer and on very first screen find a message like this:

'DEL to enter setup'

'Press Esc to Enter Setup'

'BIOS Configuration: F2'

'F10 to Enter Setup'

Carefully find any message on your screen and press respective key to enter in BIOS.

Once you enter in BIOS setting, go to Advanced Options and select Processor then No Execute Memory Protection, if not, then Security > Options and Select Execute Disable. Change this to 'Enable' or 'On'.

Save changes and Exit Bios Setting if you perform Windows 8 installation in a new PC, otherwise move on to next step

Enable Virtualization Technology (VT) feature

Go to BIOS setting by following above-mentioned steps. Go to Performance options. Change the Virtualization feature to 'Enable' or 'On'. Save changes and Exit BIOS setup. Proceed to next step if your system supports the security feature. This is how you can solve the issue.

Doesn't enable virtualization

To determine whether your PC supports hardware virtualization:

Step 1. Does my PC have a CPU with support for hardware virtualization?

Download and run the Hardware-Assisted Virtualization Detection Tool

If you receive the message This computer does not have hardware-assisted virtualization, your computer does not meet the hardware requirement for Windows Virtual PC, but you can still use Windows 7 XP Mode by running this hotfix. Be aware that XP Mode will run much better if hardware-assisted virtualization can be enabled.

If you receive the message Hardware-assisted virtualization is not enabled on this computer, go on to Step 2 below.

If you receive the message This computer is configured with hardware-assisted virtualization, download and install Windows Virtual PC and Windows XP Mode.

Step 2. Does my PC BIOS support hardware virtualization, and is it turned on?

Instructions to turn on hardware virtualization in your PC BIOS are specific to OEM models. It is important that after changing your BIOS settings the PC is completely shut down at the power switch before restarting so that the new BIOS settings can take place.

Examples for some models of some computer manufacturer's BIOS settings are below:

Sample instructions for your PC

Expand all

Dell systems

Depress the F12 key when boot menu text appears at startup

Select BIOS setup and depress the Enter key

Using the mouse, expand the Virtualization Support menu item by clicking on the plus to the left of Virtualization Support and select Virtualization

Check the Enable Intel Virtualization Technology checkbox

Click Apply

Click Exit

Fully shut down (power off), wait a few seconds, and restart your computer

HP systems

Depress Esc key when prompted at startup

Depress the F10 key to Configure BIOS

Scroll to System Configuration using the arrow keys

Select Virtualization Technology and depress the Enter key

Select Enabled and depress the Enter key

Depress the F10 key to save and exit

Select Yes and depress the Enter key

Fully shut down (power off), wait a few seconds, and restart your computer

Lenovo ThinkPad systems

Depress the blue ThinkVantage key when prompted at startup

Depress the F1 key to enter the BIOS setup utility

Using the arrow keys, scroll to Config and depress the Enter key

Scroll to CPU and depress the Enter key

Scroll to Intel Virtualization Technology and depress the Enter key

Select Enabled and depress the Enter key

Depress Enter key to continue

Depress F10 key to save and exit

Select Yes and depress the Enter key

Fully shut down (power off), wait a few seconds, and restart your computer


PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.


PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.


PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.


Depress the F2 key when boot menu text appears at startup

Select Advanced menu in Setup Utility

Change "Intel Virtualization Technology" setting from Disable to Enable

Depress F10 to exit Setup Utility

Select Yes in confirmation menu

Depress Enter to exit confirmation menu.

Please note the instructions above may not work in all cases and consulting with your computer manufacturer may be necessary. Additionally, we expect hardware virtualization to become more available when Windows 7 is shipped, particularly in business-class PCs. For those PCs that come pre-installed with Windows XP Mode we recommend the computer manufacturer turn on hardware virtualization before shipping the PC.

Once you have confirmed your PC supports hardware virtualization
Download and install Windows Virtual PC and Windows XP Mode

hope this helps

Virtualization is not showing up in the bios

The first machines to support virtualization commercially were IBM mainframes in the 1970s. It has taken PCs nearly 40 years to catch up.
Until a few years ago the central processors in PCs were not virtualizable except by using slow emulation or tricks. However both AMD and Intel have recently produced processors which include extra modes and instructions that allow full, hardware-accelerated virtualization.
AMD and Intel's virtualization techniques are different and incompatible, but all hypervisors hide the differences from you.
There are also several generations of virtualization technologies available. Initial implementations from both AMD and Intel were quite slow, and great improvements have been made over time. These differences are not very visible to the end user, but we cover some of the virtualization flags that you might see below. The upshot is that more modern processors are not only faster, but the virtualization will be more efficient too.
# A good start is to look up the model number of your CPU on the manufacturer's site. The accurate model name and number should be in /proc/cpuinfo after boot, and you can look these up on the following pages:
For example, my laptop's Intel i7 620M page is here.
The Intel site is the most useful, and will tell you directly if the processor supports virtualization (Intel VT-x) and/or secure passthrough of PCI devices to guests (Intel VT-d). The AMD site is less than useful in this respect. I have noticed some inaccuracies on the Intel site.
# /proc/cpuinfo will tell you if the processor supports virtualization and if it is enabled (but it could not show up in flags because it is disabled - more on this below).
The flags to look out for are:
  • vmx - Intel VT-x, basic virtualization
  • svm - AMD SVM, basic virtualization
  • ept - Extended Page Tables, an Intel feature to make emulation of guest page tables faster.
  • vpid - VPID, an Intel feature to make expensive TLB flushes unnecessary when context switching between guests.
  • npt - AMD Nested Page Tables, similar to EPT.
  • tpr_shadow and flexpriority - Intel feature that reduces calls into the hypervisor when accessing the Task Priority Register, which helps when running certain types of SMP guests.
  • vnmi - Intel Virtual NMI feature which helps with certain sorts of interrupt events in guests.
# The next thing to look at are the kernel messages by running the command:
dmesg ' less The two messages to look out for are:
kvm: no hardware support
kvm: disabled by bios
Note: You will only see these messages if the KVM kernel module has tried to load. That is, if you tried to start a guest already, or if you tried to load the KVM module by hand (see the next section).
The no hardware support message is self-explanatory. The disabled by biosmessage requires some explanation. When virtualization first came to PCs there was a worry that malware (on Windows of course) might use the virtualization feature in order to sit under the operating system like a hypervisor, and become especially hard to remove. Therefore virtualization can be completely disabled at boot time, requiring a reboot and manual BIOS configuration to enable it, which of course malware would not be able to do. This plan is good in theory, but it discounts one factor: the inability of motherboard manufacturers to create BIOSes that aren't full of bugs. You may find that even though your processor supports virtualization, it is not featured in the BIOS (hence impossible to enable), or the BIOS may contain bugs that prevent you from enabling it. There's not much you can do in these situations except to try updating the BIOS or replacing the motherboard.
# You can try to load the KVM module by hand.
As explained above, there are two different brands of virtualization (from Intel and AMD) which are incompatible. Therefore KVM has separate device drivers for each.
To load KVM on an Intel processor:
modprobe kvm_intel To load KVM on an AMD processor:
modprobe kvm_amd
Check dmesg output after this to see if there were any problems. Check lsmod to see if the modules were loaded.

Whats meaning of AMD ATHLON 3600+ ?

Hi Good day!! AMD's Virtualization (AMD-V) technology, which takes some tasks that virtual machine managers (VMMs) perform in software, through emulation, and simplifies them through enhancements to the AMD Athlon 64 and Opteron instruction set. AMD Virtualization Technology was announced in 2004, under the code-name Pacifica, and AMD released technical details in mid-2005.

Converting to Windows Media Player file seems to take an extremely long time. I am using a Windows XP virtual machine on a MacBook Pro. Is there some way to speed this conversion up. Thanks.

Encoding music is always a long process, in a virtual machine is even longer, if your processor supports it you might enable VT to speed up virtualization. You might also install windows via bootcamp and forget about virtualization at all.
