I am really new to Windows Phone 8 App development. I would be grateful to you if you can answer my question. I have a machine with Intel(R) Core(TM) i3 processor and when checked I found out that my virtualization setting enabled.
I installed Windows Pro 8.1 in to my machine and then it indicates that my Hyper Visor is default switched off and I had to run it. But when I run it after making some of the changes by restarting the machine, suddenly for some unknown reason it undoes every change made finally leaving the machine with no Hyper Visor running.
I come across the same process when I am to run the Windows Phone emulator to test Windows Phone 8 Apps.
I hope my issue is clear to you all, can someone help me to fix this issue or tell me the exact reason behind this?
I would look at my Windows Event log and see if you perhaps there's a problem with Hyper-V being incompatible with a driver or something like that. It may be failing to reboot and the doing a system restore to get the machine back to a bootable state (by rolling back Hyper-V). I've had problems with Hyper-V and my HP laptop's blue tooth drivers:
Here's the thread where I found out about that:
HP Bluetooth / Hyper-V woes
Updating the driver to the newest version on HP's site fixed my computer for a while, but then I had problems with Windows Update hosing my machine with an update to the Bluetooth driver.
I seem to have fixed it for good by going to RA Link's website and downloading a version of the driver that's newer than the one on HP's website. I'm not at my personal computer right now, but if you'd like I can see if I can find the driver version that seems to have fixed my Bluetooth/hyper-v problems for good.

I am using VMWare Workstation 14, with Windows Server 2016 installed on it. A few weeks ago in my server class, we had an in class lab to setup a Nano Server. I successfully got that up and running and installed Hyper-V and loaded it into it. Started up, and signed in. Then two days later at class again, the VM just freezes at the windows logo with circling white dots.
I have installed multiple VMs trying to get it up and running. Always the same result. I have the virtualization enable in BIOS on my laptop.
I have a VM snapshot I just took before installing Hyper-V, installed the role, rebooted, and again, stops at the windows logo with circling dots.
I don't know where to check if there is an issue, or if something is configured incorrectly. I am just looking for some help and ideas on what I should check. I do also have the virtualization stuff within VMWare enabled under the properties for the VM.
System details:
Asus GL502VMZ
Version 10.0.17134 Build 17134
Processor Intel(R) Core(TM) i7-7700HQ CPU # 2.80GHz, 2808 Mhz, 4 Core(s), 8 Logical Processor(s)
Installed Physical Memory (RAM) 16.0 GB
NVIDIA GeForce GTX 1060 3GB
Have you tried uninstalling the anti-virus? I was running into the same issue in my server class (Using VMware to run server 2016 which we where using to nest hyper-v)until a class mate said he didn't have the AV (we where looking for differences on why his worked and mind didn't). I removed my AV (was AVG) now the server no longer stalls at the boot screen.
Just my 2 cents that may help someone in the future. I had the same issue on an HP Proliant ML310e that worked fine for the full install until enabling the Hyper-V role, then it would hang at the Windows icon screen with the swirling dots. I was able to get past that by disabling Intel VT-d in the bios. Not a particularly good solution, but it allowed the system to boot successfully and run normally.
Goal
I was attempting to install Elastix 4.0 on a home PC via a Bootable USB, but never had any luck getting it to install past the CentOS7 part (it kept giving me a "Warning: /dev/root does not exist" error).
What I've Tried
My main PC is Windows 10 Pro, so after downloading the latest Elastix 4.0 .iso from "http://www.elastix.com/en/downloads/" (Elastix-4.0.74-Stable-x86_64-bin-10Feb2016.iso) I used UNetbootin to create my Bootable USB for Elastix 4.0. I put the now Bootable USB into the PC I want to put Elastix 4.0 on and started it up.
It gave me the "Install Elastix 4" menu, so I hit enter and waited. Then the install proceeded to do its checks for CentOS7, but ended up getting stuck and gave me an error message "dracut-initqueue[580]: Warning: Could not boot." and "Warning: /dev/root does not exist".
This is where I am stuck and cannot proceed.
EDIT #1: I signed up for the Elastix forms, and someone else also had this issue. They said they downloaded the .iso and used Rufus to make a Bootable USB, and then booted the installation using the Troubleshooting -> Install CentOS 7 using Basic Graphics ... but according to them, that apparently corrupted something else and then they opted to just use a DVD.
EDIT #2: I tested this, and making a Bootable DVD of the .iso does work great for local machines. Installing it via a VM also seems to work without hassle. As a personal goal, I would like to get this working via a Bootable USB.
Research
I did some research but a lot of the solutions I've noticed are using the dd command in Linux to make a Bootable USB for just CentOS7 because it is (was?) known that UNetbootin did not properly make a Bootable USB for CentOS7, and I can't seem to find anything that would assist in making the Elastix 4.0 .iso work properly via a Bootable USB. I did try other tools such as Rufus 2.7, Win32 Disk Imager, ISO2USB, and dd for Windows, though most rendered my USB not bootable at all (Rufus worked OK, but still got stuck at the CentOS7 part). Also, installing via a CD/DVD is not ideal, as I have no CD/DVD drive (and I want to see if I can get this working via a Bootable USB drive).
There seem to be a few guides out there for trying to create a Bootable USB for Elastix 2.x, but nothing for Elastix 4.0. Reviewing those, it looks like the guides reference some files that do not exist in the new .iso (ex: ks_default.cfg). Still, my issue pertains mainly to the CentOS7 error I'm getting so I don't think this is related.
Any assistance with this is appreciated, and if you require more information from my end just let me know. I'm willing to try / re-try anything.
Thank you in advance.

Look for this line, but it may change:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Change it to:
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 inst.ks=sdb1:/dev/sdb1:/ks/anaconda-ks.cfg quiet
Hi there i solve this problem 80%.
i did some manual change at line:
inst.ks=cdrom:/dev/cdrom:/ks/anaconda-ks.cfg quiet
Mine:
inst.ks=scsi:/dev/sdb1:/ks/anaconda-ks.cfg quiet
hd is not recogniced by Centos7.
made my usb bootable with rufus 2.9
then open isolinux.cfg with notepad++
just change the line
inst.ks=hd:sdb1:/ks/anaconda-ks.cfg quiet
where sdb1 used to say cdrom
My virtual machine of 64-bit Debian 7.5 (wheezy) was working in VirtualBox 4.3.12r93733 on a Windows 8.1 Pro (64-bit Operating System, x64-based processor: Intel(R) Xeon(R) CPU E5-1620 v2 # 3.70GHz 3.69 GHz) machine (Dell Precision T3610) yesterday. But when I tried it this morning I got an error message saying: VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. I chose to continue but as promised I made it as far as choosing between system modes (regular or recovery) before the screen blacked out.
When I searched this message online I found answers saying to make sure the BIOS had virtualization enabled. My BIOS has 3 options under Virtualization Support: Virtualization, Virtualization for Direct I/O, and Trusted Execution. The first two were enabled but the last was not. (This is a work machine, so I am hesitant to load defaults without speaking to someone from IT first.)
Aside from downloading and initiating an install for Visual Studio Express 2012 (which has since been uninstalled), little has happened on this machine since the Debian virtual machine was last working. So I also investigated and uninstalled the Windows Updates from yesterday on, in case they were involved. (One in particular mentioned having to fix the BIOS.) The ones that were marked important, including the one that fixes BIOS, have been reinstalled.
At this point I started looking into VirtualBox's settings. In my online research I found several forum posts recommended going into Settings->System->Acceleration, a tab that is greyed out for me. While at Settings->System->Motherboard, I noticed my pointing device was set to USB Tablet. When I changed it to PS/2 Mouse and tried the VirtualBox again, the error message went away but the OS still does not successfully boot.
My most recent revelation happened after this: Under Settings->General->Basic, I noticed my version was set to Ubuntu (32 bit), even though I am sure it was at Debian (64 bit) yesterday. But only 32-bit OS's are options, when my machine ought to be capable of having 64-bit ones too.
My question is: What could have caused VirtualBox to lose all 64 bit options, including a working Debian (64 bit), overnight?
You probably have had Hyper-V installed and enabled.
Cross check and Disable the setting from :
Control Panel >> Programs and Features >> Turn Windows features on or off
Reference : https://forums.virtualbox.org/viewtopic.php?f=6&t=57926
try this on virtualbox:
go to your virtual machine setting (right click on VM icon > setting) then go to system > acceleration and ensure that "Enable VT-x/AMD-V" checkbox is checked.
I have this error message:
The windows phone emulator requires Hyper-V. Your PC is missing the
following pre-requisites required to run Hyper-V:
I cannot run my project on windows 8 phone emulator since days. I searched on internet, still I couldn't solve my problem. Everyone says open Control-panel, then click turn-off or turn on windows features, then choose hyper-v option. When I clicked turn off or turn on windows features there is no option about Hyper-V. Can anyone help me?
My computer features:
windows-8 Professional (64Bit)
intel core i7 processor
8Gb ram
First step
1- turn on hyper-v from bios
read this :
http://blogs.technet.com/b/canitpro/archive/2014/03/11/step-by-step-enabling-hyper-v-for-use-on-windows-8-1.aspx
2- turn on hyper-v from windows
At the Start Screen, swipe the right hand side of the screen and select the Search Charm.
Type turn windows features on or off and select that item.
Select and enable Hyper-V.
If Hyper-V was not previously enabled, reboot the machine to apply the change.
I formatted my os from windows 8 pro to windows 8 enterprise and I solved my problem easily.I know it is not a logic solution but it worked.
In order to run Windows Phone 8 emulator you need to enable Hyper-V technology in the BIOS of your PC. See the detailed article on how to do this.
First you must turn on hyper-v from bios and then turn hyper-v from windows featured list restart and then will work ..
The RTM version of Win8 needs Execute Disable Bit to be enabled from bios in order to install itself. My current bios doesn't show any option to enable/disable this function and unless i burn a DVD to test the installer i won't know if Win8 will run on my laptop (my CPU is an i5-2430M that supports XD Bit), if XD Bit has always been enablet or if HP removed the option to enable it from the bios.
There should be an instruction/system call that let the user know if his/her machine is running with NX Bit enabled (or any other implementation, like XD Bit, Enhanced Virus Protection etc.), since the Win8 setup does this trick, but i can't find on google. Any info?
If you're using Windows now you can go to
My Computer->Advanced System Settings->Advanced (tab)->Performance (settings button)->Data Execution Prevention to check if it's enabled.
That sounds great I hope is gonna fix my problem with Windows 7 and Im tryng to installl in Vmware Windows 8 but i have a dude it also works if you reboot your system with a booteable image W8 and try to install removing your windows 7?
