Windows 8?

[psyfox]

still have problems to install windows 8 rtm on:

virtualbox 4.2.4r81684

As started, the vbox says:

VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Certain guests (e.g. OS/2 and QNX) require this feature.
Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer.

(yes, its enabled)

When trying to install w8 x86:

Your PC needs to restart.
Please hold down the power button.
Error Code: 0x0000005D
[...]

(yes, disable bit enabled, etc etc)

I know its a known problem. I'm here trying to help. So ppl should stop crying about a costless tool.

Then something else is using it. Since only one instance of anything using VMX is possible you need to find out what and disable it. Hyper-v, some google apps, some virus software, & some debugging tools have been found to cause this.

[Grayghost]

I seem to have the same problem.... How do I find out what is using this feature and disable it ???

[BillG]

That really has nothing to do with how VirtualBox works. That is purely a problem with the host OS and the programs running on the host. From the host OS you would look at what programs might be causing it and prevent one at a time from starting until you find which of them is locking VT-x.

[robatino]

It does detect NX and passes it through. Otherwise the Windows 8 setup program would immediately say the machine does not support Windows 8. Instead, it loads for a while and then goes into a hard CPU loop -- or at least the VirtualBox executable does. I don't know how to tell if the VM is executing or halted waiting for something from VB and VB is in a CPU loop.

Below is a comparison of the output of coreinfo run in the host (Windows 7 Ultimate x64) and coreinfo run in a VM (Windows 7 Ultimate x64). NX is shown as available in both.

There are a few items that are only exposed on the host:
Hyperthreading
Supports AMD hardware-assisted virtualization
Implements AMD MMX extensions
Supprots CMPXCHG16B instruction.

The guest has only one core whereas the host has two.

I am having similar trouble getting either the 32- or 64-bit Windows 8 DVD to boot. Each displays the blue window on a black screen and then just sits there using almost 100% CPU. My host is Fedora 17 64-bit with VirtualBox 4.2.4. The output of "cat /proc/cpuinfo" is

Host Hardware: Lenovo Thinkpad 201X
Host: Windows 7 Ultimate x64
Guest: Windows 8 Pro

I am trying to get bluetooth working in the guest. I have connected the bluetooth adapter to the guest. That appears to work be cause when I start the guest the bluetooth adapter disappears from the host's device list and appears in the guest's device list.

I have enabled allow others to find this device.

I do a search for Bluetooth, click on settings and click on Add bluetooth device. The system searchs but cannot find any.

If I shutdown the guest and do the same type of thing on the Windows 7 host I can see both my cell phone and the bluetooh adapter on another machine and I can add the cell phone as a device.

Like wise if I do a search from my cell phone it will find the Windows 7 host. If I then start the guest and again do a search from my cell phone it cannot find the host or the guest.

What do I have to do to get bluetooth working in the guest?

[scp]

I have a similar problem like robatino and saberman: No matter If I boot from Installation DVD or HDD, it hangs at boot with black screen with blue windows logo most time.
But I found a dirty workaround: If I wait for the hang, press Host+R wait for the hang and repeat this up to ten times, then Windows 8 boots. Once it is booted it works normal like any other VM.

Throwing my hat in the ring with the same symptoms too (as scp, robatino and saberman): No matter If I boot from Installation DVD or ISO x64 or x32, it hangs at boot with black screen with blue windows logo. However, unlike scp forced resets don't get me any further along. So it never gets to the start of the installation.

Using VMWare Player 5 on the same Windows 7 x64 Host (obviously not at the same time), Win8 installation and operation works normally.

Consistently, I get Blue window on black screen, no rotating dots, and brief CD-ROM activity followed by a blink of the HDD activity light in the status bar at the bottom of the VM, then steady state hang. VirtualBox.EXE @ 51% CPU and just under 50M Memory from Task Manager on Host. I have to manually power off the VM (Host+Q).

Attached is the VirtualBox log file.

Win8-64bit installation issue with SATA...

Host: Win7prof-64bit with VB 4.2.4r81864
Guest: Win8prof-64bit

If default Win8-64 guest settings used with SATA hd controller, installation stops while 'expanding files' nearly 35%, see attached log:
http://on.yourweb.de/VBoxWin8.zip.
Installation can be fixed with choosing IDE controller with PIIX4 chipset.

Similar behaviour is shown if installing VistaUltimate-64bit guest with SATA hd controller, pls see this thread:
https://forums.virtualbox.org/viewtopic.php?f=6&t=52952.

IMHO there is an issue with emulated SATA controller for 64bit Windows guests!?

I just set up a new Windows 8 guest (Mac host) and my Chrome browsers pages repeatedly get scrambled. Imagine that you could take chop up a web page into sections and spin each part into a variety of directions.

I have a screenshot but I can't post
I don't see this on my Windows 7 guest, which is why I am posting here. Can anyone tell me what this is? (Or, better, how to solve it!)

I thought I was the only one with this problem. The difference is that mine shows up on the Windows 7 guest. This problem seem to affect multimedia (flash) pages rather than stripped down forums like this one. The only work-around I found so far is to go into Chrome's plug-in setup and disable flash. This will make the multimedia pages display normally, mostly. Every now and then, I can still see an occasional flashback to the scrambled pages, but only in a fleeting instance.

I'd love for someone to show us the way out of this doghouse.

Despite people are saying that Windows 8 is not good as it is very slow but I am strongly dis-agree with them as I am using this OS and found that it is very fast as it has very less loading time. This is also a thing which is helpful to increase sales.By the way i forgot my windows 8 password and reset it with SmartKey Windows Password Recovery last Monday.

Regarding the vt-x/amd-v problem with 64-bit guests, I have a Dell Inspiron 530 where the BIOS does support hardware virtualization and it was confirmed running VMWare 64-bit guest check (more info at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003945). What I found out that my BIOS (and I'm sure others as well) have a bug where awakening from hybernation/hybrid sleep/sleep fails to maintain the hardware virtualization setting. More info here: http://communities.vmware.com/docs/DOC-8978. Dell has, as usual, abandoned support of its products, and has chosen to deliberately refuse to fix this BIOS bug (along with other bugs that have been reported - last BIOS update was in 3/09).

Has anybody noticed small defects on elements with rounded corners in IE10 in virtualbox?

[borderer]

Re NX problem and "Your PC needs to restart..." error, I have just discovered that the kernel of my VB host OS, Ubuntu 10.04 LTS, does not pass through the No-Execute Memory Protect setting from my BIOS, so the setting for the Windows 8 VM guest is ignored. In my case, the solution was to install a generic-pae kernel as described in Ubuntu Community website.

See ticket #11436 for further details.
