Re-explain

Hardware Requirements:

  • CPU with virtualization extensions (Intel VT-x or AMD-V)
  • Sufficient RAM (depends on VM requirements)
  • Storage space for VM images

Software Requirements:

  • Linux kernel with KVM modules (kvm, kvm_intel/kvm_amd)
  • QEMU package installed
  • libvirt (optional but recommended for management)

Verification commands:

# Check CPU virtualization support
egrep -c '(vmx|svm)' /proc/cpuinfo

# Check if KVM modules are loaded
lsmod | grep kvm

# Verify KVM device exists
ls -la /dev/kvm
