What solved my issue was using less than 3 GB of ram in the virtual box session. I was originally attempting to utilize roughly 6 GB. You are trying to allocate >3GB of RAM to the VM. This requires: (a) a 64 bit host system; and (b) true hardware pass-through ie VT-x.
On page 2916 of this Intel software developer's manual, you can see that a hardware "hook" is provided that can allow a BIOS to disable or enable virtualization. VMXON is also controlled by the IA32_FEATURE_CONTROL MSR (MSR address 3AH). This MSR is cleared to zero when a logical processor is reset. ... Bit 0 is the lock bit. If this bit is clear, ...
For anyone who may still have this issue, I've successfully resolved it. The problem is caused by the fact that Intel Virtualization Technology and Hyper-V cannot run at the same time. There are several possible solutions, pick the one that best fits you: Completely disable Hyper-V in your system. This can be done either by opening Control Panel -> ...
Acer usually disables this option on ther mid-tier laptops. First of all try a BIOS update, later versions may have it enabled. If you want it enabled even if the manufacturer doesn't want you to, you can probably flash a modified BIOS, but this is VERY RISKY BUSINESS. You will probably void your warranty, may end up with broken notebook, get yourself a ...
Reducing RAM in VirtualBox from 4gb to 2gb worked for us when we had only RDP to host machine so couldn't access BIOS.
This is not a duplicated question. What OP is trying to do is something like this: Host A(with VT-X support)->virtual machine B-->some applications need VT-X and getting VT-X support inside B so applications -- may be another VM or emulator -- running inside B, can take advantage of vt-x. Its called "Nested Hardware Virtualization", supported by ...
Intel Virtualization Technology (VT). Formerly known as Vanderpool, this technology enables a CPU to act as if you have several independent computers, in order to enable several operating systems to run at the same time on the same machine. In this tutorial we will explain everything you need to know about this technology. Intel’s virtualization technology ...
I don't believe that you can run Hyper-V within a guest as there is already a hypervisor running. (Pretty sure it tells you this if you try and install the hyper-v role). I think your just going to have to run these other machines on the host server.
Actually sometimes vendors of motherboards (mostly notebook ones - a 2430M seems to be a notebook processor, so I can assume that you have a notebook) lock this option - hide it from the BIOS menu. There could be three ways to enable it - first one there MAY be an utility from the notebook or motherboard vendor which could enable or disable it. Second one - ...
Just ran this on my box at home and I can confirm the latest version of CPU-Z directly from the website works correctly on Windows 10. It detected that my CPU supported VT-x and listed it in the instructions section. Without checking if you have VT-x enabled in the BIOS, everything is probably just guessing.
There's nothing surprising about this. Windows 10 is using the virtualization feature of the CPU, as it says it is. CPU-Z is therefore running on a virtual CPU which does not itself support virtualization. Before, your OS wasn't using the virtualization feature of the CPU. So that left it available for programs like CPU-Z to detect and use. Unless nested ...
