Ultimate QEMU/KVM Guide

Professional Virtualization Knowledge Base

๐Ÿš€ Performance Tips
  • Enable KVM acceleration (10-20x faster)
  • Use VirtIO drivers for disk/network
  • Allocate huge pages for >4GB VMs
  • CPU host passthrough when possible
  • Q35 machine type for modern features
  • NVMe for maximum storage performance
๐Ÿ›ก๏ธ Security Best Practices
  • Use UEFI instead of legacy BIOS
  • Enable TPM 2.0 for Windows 11/BitLocker
  • Run VMs with non-root privileges
  • Snapshot mode for testing untrusted code
  • Secure Boot for supported OS
  • Sandboxing for isolation
โš ๏ธ Common Issues
  • VT-x/AMD-V must be enabled in BIOS
  • Install VirtIO drivers for Windows
  • Bridge networking needs host setup
  • GPU passthrough requires IOMMU
  • TPM needs swtpm package
  • User must be in 'kvm' group
๐Ÿ’ป Host Requirements
  • CPU: Intel VT-x or AMD-V support
  • RAM: Host + all VM memory
  • Storage: Fast SSD recommended
  • Packages: qemu-kvm, libvirt
  • Kernel: KVM modules loaded
  • IOMMU: For device passthrough
๐Ÿ—๏ธ Architecture Guide
  • x86_64: Intel/AMD 64-bit (most common)
  • i386: 32-bit legacy systems
  • aarch64: ARM 64-bit (M1, servers)
  • arm: 32-bit ARM (Pi, embedded)
