以前Linux Debian12安装VirtualBox虚拟机平台，都是按照Linux Debian11安装VirtualBox虚拟机平台解决方法处理，都能正常运行。 现在Linux Debian13安装VirtualBox7.2.2虚拟机平台，也是按照上面方法解决，但是还是无法运行，出现下面问题：
VT-x is being used by another hypervisor (VERR_VMX_IN_VMX_ROOT_MODE).
VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE).
我的解决方法如下：
This error occurs when another hypervisor (usually KVM on Linux) is already using the VT-x virtualization extensions, preventing VirtualBox from accessing them. Here are several solutions:
Solution 1: Disable KVM (Most Common)
Check if KVM is loaded:
lsmod | grep kvm
Unload KVM modules:
sudo modprobe -r kvm_intel # For Intel CPUs
# OR
sudo modprobe -r kvm_amd # For AMD CPUs
sudo modprobe -r kvm
Make it permanent by blacklisting KVM:
sudo nano /etc/modprobe.d/blacklist-kvm.conf
Add these lines:
blacklist kvm
blacklist kvm_intel # For Intel
# blacklist kvm_amd # For AMD
Then update initramfs and reboot:
sudo update-initramfs -u
sudo reboot
重启后，都能正常运行
