在Linux VirtualBox中安装系统失败

Problem：

Reason

Encountering a VT-x / AMD-V hardware virtualization conflict in Ubuntu with VirtualBox.

Most Likely Solution:

Ubuntu often has KVM (Kernel-based Virtual Machine) enabled by default, which conflicts with VirtualBox's own virtualization engine.

Steps to fix:

1. Check if KVM is running:

lsmod | grep kvm

If you see kvm_intel or kvm_amd, KVM is active.

2. Disable KVM temporarily for this session:

sudo rmmod kvm_intel
sudo rmmod kvm_amd
sudo rmmod kvm

3. Try starting your VM again.

If that works, make it permanent:

4. Prevent KVM from loading on boot:

sudo sh -c 'echo "blacklist kvm" >> /etc/modprobe.d/blacklist.conf'
sudo sh -c 'echo "blacklist kvm_intel" >> /etc/modprobe.d/blacklist.conf'
sudo sh -c 'echo "blacklist kvm_amd" >> /etc/modprobe.d/blacklist.conf'

5. Update initramfs:

sudo update-initramfs -u

6. Reboot:

sudo reboot
