I'm new to the virtualization world, just trying to install Redis on windows 10
I keep getting this error
virtual machine could not be started because hypervisor is not running
even though virtualization is enabled in bios, windows features and task manager shows the virtualization is enabled
I've no idea what's wrong
my CPU is intel core 2 quad q9650 idk if it matters or it's the right place to ask
I'm trying to run TwinCat 3 XAR in a PC where I need to have hyper-V ON to run Azure IoT Edge (which uses hyper-V). Is there a way to run XAR with hyper-V turned on? Is there any way to isolate the cores from hyper-v or something else?
Edit 22 April 2022
For a complete tutorial on this see my blog post.
There is a way to accomplish this. You can do this by instead of having a local runtime, you can run the code on a runtime in a virtual machine. I got the idea from this reddit post.
To make it work I did the following:
Download and install VMware Player. Its free for non-commercial use. You can also use the paid Pro (Workstation) version. I'm not sure if this also works with Virtual Box.
Install TwinCAT BSD on the virtual machine as described in this excellent YouTube video by Jakob
If you're using VMware Player and need to enable UEFI you need to do the following as noted by YouTube user Eivind Hilde:
Follow the guide in the video, but skip the step where the firmware type is set.
Try to boot the VM. it will fail.
Open the .vmx file in the VM directory with notepad .
Find "firmware = "bios" and replace with "firmware ="efi"" and save. If this line doesn't exist, just add it somewhere.
It will now boot, and you can follow the guide in the video for the rest.
Run your TwinCAT project on the virtual machine, without the need to disable Hyper-V. 🎉

I don't think so. InfoSys mentions:
Hyper-V environment:
The runtime environment cannot be started inside a Hyper-V environment. This refers in particular to virtual Hyper-V machines, which are run in a privileged Hyper-V machine. As soon as a component of the computer uses Hyper-V, only the engineering environment (XAE) can be used on this computer, not the runtime environment (XAR).
But they also mention that:
TwinCAT attempts to detect these Hyper-V environments; however, it is in the nature of virtualization approaches that they do not wish to be detected and TwinCAT therefore cannot carry out any 100% detection.
So maybe there is some way you can prevent TwinCAT from detecting a Hyper-V environment. However, that is something I can't answer.
I was installing vagrant with virtualbox provision. When I am running it on Amazon EC2, then it doesn't work saying:
* Running VirtualBox in a Xen environment is not supported
EC2 uses xen virtualization. On the other hand, its working fine on Windows Azure Virtual Machines which uses a customized version of Hyper-V.
So,cant we use virtualbox in Xen but in Hyper-V?
Are you sure that HyperV allow you to start the VM, I don't think this is possible using current hardware VT technology without slow painful emulation instead of virtualization.
Adam Lewis answered, "I have switched to running Matlab on Parallels Desktop on my 2008 Mac Book Pro and have Zero issues". I have been unable to get a Mac-version of MATLAB v.7x to either install, or to run as a Mac program within Windows, on Parallels v7 virtual Windows7Prof, on my 13" MacBook Air.
Does it require a PC-version of MATLAB for the virtual machine?
Yes, it requires a Windows version.
If you install any software on a Virtual Machine, that software needs to be compatible with the guest OS (Windows in this case).
A virtual machine is exactly what it says: a virtual machine. So for any software, it will seem as if it's running on a real machine with that configuration (OS, CPU, RAM, ...). It doesn't really matter what the host machine is: that could be a Windows, Mac or Linux host or even your toaster.
Yes, if you plan to run MATLAB on a Windows virtual machine, you need the Windows version of MATLAB.
... But consult a local expert for help. Installing the Mac version of MATLAB should be effortless.
It seems that the Windows Phone 7 SDK doesn't support running inside a VM. On Parallels, the entire VM simply crashes when the emulator is starting up.
Around the web, though, a few people have reported that they were able to use it by changing a lot of the VM settings.
What do I have to change to be able to run it? I'm specially interested in Parallels, but VMWare or any other simulator that run on OSX if fine for me!
The WinPhone7 (and WinPhone8) emulator is itself a VM and few (if any) general-purpose VM's will host another VM infrastructure, which is why it crashes Parallels etc.
If you want to have the emulator run from within a different VM to the one MS provides, then you're into the realm of extracting images, toggling bits and trying to tack it into your VM of choice. Of course, the chances of the emulator then working as expected with no residual issues is as close to nil as makes no difference ;)
[Update 2013-01-30] VMWare5 & Parallels Desktop 8 now support running Hyper-V guest VM's. This is particularly useful for those wanting to develop against the Windows Phone 8 SDK which runs Windows Phone 8 guest VM's on Hyper-V.
Here's a guide to how to run Visual Studio 2012 & Windows 8 SDK (inc. the Windows Phone 8 Hyper-V-based emulator) in VMWare5 or Parallels desktop 5: Link
Note: Running Windows & Hyper-V inside a VM will be slower than running natively. Dual-booting into Windows (using Boot Camp on OSX) is stil the recommended method of developing for the Windows platform, especially if you want to use Hyper-V guest VM's.
I'm working in VMware Fusion with Expression Blend 4 RC AND the emulator.
works like a charm!
As others have said, WP7 is itself a virtual machine. Even if you can get it to run inside a virtual machine like Parallels, the performance will be abysmal. If your computer supports hardware virtualization, the emulator runs really smooth, without it it's very very sluggish. Running it inside another VM will make it even more sluggish - I am guessing to the point that it's unusable.
I know this is not the answer you want to hear, but I would recommend running Windows in Bootcamp, you will have much better experience developing and emulating.
I'm not so sure about compatibility for long term development, but in last september, I remembering trying the Windows Phone 7.1beta SDK on VirtualBox (I'm using mac SL), a free virtual machine from oracle (previously by Sun) and it works well there.
I just do a regular install of Windows 7 Home Basic (any Win7 except Starter will do, CMIIW) in the VBox with no tweaking at all, install the GuestAddition inside win7 (provided by VBox), then install the SDK. I create new WP project, arrange UI, make some codes as usual, then run it in emulator. Surprisingly, the emulator works fairly well and showing the app I've developed.
I'm not even experience any lag (my macbook is i5, 4GB ram, the VBox setting is dual core, 2GB ram, note that no other heavy mac process is on the run, so I solely run the VBox ... and iTunes for listening musics).
So if you still want to try WP SDK 7.1 on VM, why don't you try VirtualBox? My current VBox is installed with Windows 8 and have no extra space to reinstall the win7+WPSDK. If you do give a try on VBox, please report the result here to inform everyone.
I've run the Android emulator inside a VM before. It was slower, but still usable to test basic apps. Also, the Android emulator was then slow to where you couldn't tell a difference from between native or from within running Eclipse from within a virtual machine running Linux
x86-to-x86 emulation tends to be pretty fast nowadays due to both Intel and AMD CPUs having hardware to help it along. A lot of x86-to-x86 emulation also doesn't do a full emulation (see Android's emulator to see how a full emulator runs in comparison). In the x86-to-x86 case, the faster ones will try to pass as many instructions to the host OS so that a chunk of the code runs natively
People have made claims like 80-95% performance, which is pretty good. If you have a 3.2 GHz CPU, you get knocked down to around a 2.4 GHz equivalent of your CPU. That's not bad at all, and I honestly don't notice that much overhead running in a good x86-to-x86 VM
The biggest reason why the WP emulator has problems with VMs doesn't have to deal with it being a VM-in-a-VM, but it's most likely that it requires DirectX 10. This might have to do with XNA, which is Microsoft's really nifty gaming API that lets you easily port between Windows, WP, and the Xbox 360. A lot of VM programs don't support hardware 3d acceleration
On another note: if you want to use a low-end system, AMD CPUs may fare better since AMD doesn't tend to disable hardware virtualization features in their lower-end CPUs
If you're deploying to a device, you should be able to use a VM, since it's the emulator that has issues being a VM itself.
We have successfully deployed, and performance is acceptable in our environment, virtual Windows 8.1 Pro Desktop under VMware vSphere 5.5 (ESXi 5.5), and have the Windows 8 SDK and Emulator working correctly with no performance issues. (In Education - to University Labs for Windows Phone development).
The issue experienced by most, is you most have the Hypervisor pass through the Intel-VT into the VM, to effecticely create Nested Hypervisors. This is possible using VMware vSphere 5.5.
This option is available in virtual machine version 10, enabled in the vSphere Web Client - Enable Hardware Virtualisation.
