failed to open a session for the virtual machine - virtual-machine

i have this problem when opening a virtual machine in virtual box:
Not in a hypervisor partition (HVP=0) (VERR_NEM_NOT_AVAILABLE).
VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
Result Code:
E_FAIL (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
i searched for a solution and i found that i must enable the virtualization from the the BIOS setup but when i checked it i found it enabled. can anyone provide me a solution?

Start your PC, press F2 or F12 or DEL, go to the security option and enable VT technology.
In some new BIOS, it called Virtual technology or Intel virtualization in the CPU setting option

Network card error while creating Solars 11 VM on hyper-v

I am trying to create Solaris 11 VM on hyper-v.
While installing Solaris I get following message:
No Network interface found , addition driver may be needed.
When installation is done , My IP is not configured in machine.
I found one link where same problem is mention but solution is not clear to me.

Any help is much appreciated.Thanks
You will need to open up VMWare Workstation, or your VMware app, Go to Settings for your VM, and look for "Network Adapter".
The default is NAT. If that doesn't work, try bridged, or cycle through the options to see if any are supported.
If that doesn't work, you may need to add a new network device. In that case, you will need to do this:
Select Window > Virtual Machine Library.
Select a virtual machine in the Virtual Machine Library window and click Settings.
Click Add Device.
Click Network Adapter.
Click Add.

How do I this fix VERR_VMX_MSR_ALL_VMX_DISABLED in Virtual-Box?

After installing windows 98 in virtualbox, I clicked 'start' button. Then it showed me an error:

You need virtualization Technology enabled in the Bios
Reboot your machine
Press F10 to enter BIOS.
Security-> System Security
Enable Virtualization Technology (VTx) and Virtualization Technology
Save and start the machine.
Failed to open a session for the virtual machine windows 98.
There are different approaches to solve this, try whichever works for you
1
open windows features win+R --> then optionalfeatures
Disable Hyper-V (if it is available on your machine)
Enable "Virtual Machine platform"
Enable "Windows Hypervisor platform"
Disable "Windows Sandbox" (if available on your machine)
Restart the machine
2
Windows Subsystem for Linux (WSL) feature was enabled.
Disabling it solved it for me.
Restart the machine.
3
If it still doesn't work:
Open Powershell command prompt as admin and then run the following command:
bcdedit /set hypervisorlaunchtype off
Restart the machine

How to enable VT-x inside a Virtual Machine inside a Virtual Machine

I have a windows 10 host operating system that supports virtualization. Next, I have an Ubuntu 16.04 virtual machine I created using virtualbox. For development purposes, I need to create a virtual machine inside my guest Ubuntu virtual machine. Unfortunately, I can't enable VT-x option in my guest Ubuntu machine to create a create a virtual machine inside my Ubuntu guest. Any information on how enable VT-x option on my virtual box inside my virtual Ubuntu machine would be appreciated.
Edit: I had that this may be accomplished through PCI Passthrough for VirtualBox. If so please detail how.
Lastly, my problem is similar to this guy's but with exception I can't seem to create an UBuntu32bit box.
Any information on how enable VT-x option on my virtual box inside my virtual Ubuntu machine would be appreciated.
You simply CAN'T.
VT-x is a hardware capability:
In 2006, both Intel (VT-x) and AMD (AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models.
Since VT-x requires hardware capabilities to work, there's no way for the "outer" virtual machine in your nested VMs to provide that capability to the "inner" VM. The "outer" VM doesn't have any actual hardware.
If you have to run a VM inside your VM that requires some of the capabilities that VT-x provides - such as the ability to run a 64-bit OS - you can try QEMU for the "inner" virtual machines. It'll be slower since it's an emulator and not true virtualization, though.

Run real "Bios Setup" in virtual machine

Normally if we want to change Bios Setting, we need to restart the PC and when system boot up we press the hot key (F2 or F10) to go "Bios Setup", then change the setting.
However, I would want to do real Bios Setup from Window Environment...Is it possible to copy the image of Bios (of my computer) to a binary file? then setup a virtual machine to run it and do all the changes? If it is impossible with existing tool (VirtualBox, Qemu,VMWARE)...is it possible to write a special virtualization software to do that?
Thanks
Go to your settings of the virtual machine go to system > motherboard click EFI on
Boot your machine and type in the shell (you need to wait a bit)
"exit" then you will go into the BIOS EFI if you want to quit hard power it off and to turn off the bios for boot again reverse the settings...

Cannot use the usb wireless card in virtualbox host:OSX guest:BT5

i have try many solutions in internet and all solutions does not work to me. i set the usb filter of usb setting in virtual box, but it keep to pop-up error for me.
Here is the errors:
Failed to attach the USB device Ralink 54M.USB....... [0001] to the virtual machine BT5.
USB device 'Ralink 54M.USB.......' with UUID {ID} is in use by someone else.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: HostUSBDevice
Interface: IHostUSBDevice
Callee: IConsole
can someone help me?
thank you for any suggestions.
Your extensions for Ralink are not allowing VirtualBox to attach to it. I found out that the Ralink wireless utility or the driver won't release it to the guest OS on VirtualBox. I deleted the kext (making sure I backed it up first) and rebooted. Now the VirtualBox guest OS (bt5 r3 in my case) sees it under lsusb after recompiling the driver for it, using modprobe rt5370sta, and blacklisting the other rt2x00 and rt2800.
