Windows 8 Host

[melodia]

Trying to mount Windows 8 on VirtualBox, host machine Windows 7 64bit, I received this error message:
L'accelerazione hardware VT-x/AMD-V è stata abilitata, ma non è funzionante. Alcuni guest (ad es. OS/2 e QNX) richiedono questa funzionalità.
Assicurati di aver abilitato VT-x/AMD-V nel BIOS del computer host.
(Hardware acceleration qualified but not working ... Be sure having VT-x/AMD-V working in your host PC BIOS).
I can't find anything in my BIOS settings. CPU Intel i7 2700K, 16 GB RAM, Windows 7 64 bit.
Thanks in advance, Andrea

Look for "hardware virtualization" in your bios and make sure it is enabled.

HI, I am unable to install VirtualBox v4.1.18. My host operating system is Windows 8 Release Preview 64-bit. The installation gets passed installing the driver and registering the software and then I see a screen similiar to the BSOD with the following error:

Code: Select all

PAGE_FAULT_IN_NONPAGE_AREA

EDIT: Okay I found out the problem is with my Wireless Adapter. I cannot disable or uninstall the driver without getting the BSOD and the same error. The Wireless adapter is a Qualcomm Atheros AR5B93. I think it could be an incorrect driver so I will install the latest from Acer.

once RP enabled =1 was gone from windows 8 ....so was I.
I was a windows guy since day one.
IMO Windows 8 is so bad that you would have to Pay me to use it.

I can't believe you want to VM this OS.

My wife told me to remove it from the computer or she beat me silly. My Kids told me they wanted a new dad if I left it.

Good Luck with Windows 8 you'll need it! At least it brought you here!

Now that Windows 8 has gone RTM, is there any chance of getting support in this thread? Or should we open a new thread based on RTM?

I've tried both 4.1.22 and 4.2 RC4, and both cause Windows 8 to freeze and bluescreen. It definitely has to do with the graphics drivers.

[BillG]

And what graphic driver do you have? I have not had any problems running VirtualBox on Windows 8. (and 4.2.0 has now been released).

VirtualBox is running well for me under Windows 8 64-bit (RTM), but theming in the program isn't working (as of 4.2.0). Running VirtualBox.exe in Windows 7 compatibility mode seems to fixes this.

I just installed VirtualBox 4.2 on Windows 8 Enterprise RTM. I installs and runs fine, but I’m having trouble creating a new Windows 7 virtual machine. I attach the ISO and then boot. I get a Windows Boot Manager error: “Windows failed to start. A recent hardware or software change might be the cause…” There’s no OS installed, as this is a brand new virtual machine.

I see that a few of you say that it’s running OK for you. Are these virtual machines that you already had set up prior to using Windows 8? I’m wondering if this is just an issue when setting up a new one.

I have a minor problem in with W8 as a Host OS, Seamless seems to be disabled, it is greyed out, tried reinstalling Guest additions several times, in and out of Safe mode, with and without Direct3D support. Everything else seems to be working flawlessly so far.

EDIT:
Turns out something had gone wrong with my installation of SP's... I was going to get SP3 for Directx, but it told me I didn't have SP2, wich I was sure I had installed, so my SP2 installation was corrupt, reinstalling fixed everything, now I got seamless mode too.

I am running Windows 8 Enterprise x64 RTM as the host OS. I have VirtualBox 4.2 installed. None of my Windows 7 x64 (Professional or Enterprise N) can enable Aero. These same VMs running under Windows 7 Enterprise x64 using VirtualBox 4.1.8 would show Aero). The settings on the VMs are the same as previously (4GB RAM, 128MB video RAM with a single display, 3D Acceleration enabled, etc.). They are in fact the same VMs. I have tried running VirtualBox using Windows 7 Compatibility but it doesn't seem to make any difference. The VMs are running fine as far as I can tell (except for the Aero). I have upgraded the VM guest additions to 4.2 (4.1.8 and 4.2 guest additions would not show Aero under VBox 4.2).

Are people able to get Windows 8 hosts to show Aero with Windows 7 Guests, and if so, what am I missing?

Thanks much!

My experience told me that bridged mode that was supported before was broken.

Since I posted in another thread and it was told this is the on for discussion, here is my problem

«I had a VM with Windows 2008 server working with image deploying over a windows 7 x64 host.
After upgradind to the windows 8 x64 final from Microsoft Action Subscription I can't get machines to boot from PXE anymore. Even if the virtual machine is working well over network on other services (web, file server...)
Tried to uninstall, reinstall, upgrade but still not working.
I really don't know what to do next.
Any ideias ?

PS: Bridge network using virtualbox - Intel Pro/1000 MT desktop adapter used»

So if there are any news about this anyone can share ...

I have the same issue as rawk1971... Windows 8 Enterprise 64-bit as host. clean install, no upgrade. Just installed VB latest version 4.2.2.
MSI Z77A-G41 Mobo, i7 2600K w/16GB ram. Integrated video. Virtualization already enabled.

When trying to install ANY virtual 64-bit (Windows server 2008, 2012, Windows 7) I get the same error:

Install error

Also have already Win7 installed in hyper-v, but when trying to import i get an error:

If Windows 8 is not going to be supported for the time being, the following Wiki page should also be updated:
https://www.virtualbox.org/wiki/End-user_documentation
It still refers to "Windows XP and later".

Attempted install on Win8prox64 tonite w/ vb4.2.4 - no dice. Hung the PC on boot, had to use a system restore point to get back in.

Running Windows 8 Pro as Host Machine. After migrating from Windows 7 to 8, Hardware Virtualisation for Guests was not available anymore. Solved it by disabling Hyper-V (Control Panel -> Programs and Features -> Disable Windows Features -> Uncheck Hyper-V)
