🚀 The Secret to Fast Virtual Machines: Hardware Virtualization
This is where the magic happens! Modern processors (Intel and AMD) have a special technology that makes virtual machines run almost as fast as a regular computer. It is said:
- (I.e. Intel VT-x for Intel processors
- 🔴 V-AMD for AMD processors
🔍 How to check if you have it:
Download the free program LeoMoon CPU-VIt's small (a few MB) and will tell you right away:
- ✅ If your processor supports virtualization
- ✅ If it is enabled
- ⚠️ If you need to enable it from BIOS
🔧 How to activate it:
- • Intel VT-x ή Intel Virtualization Technology (for Intel)
- • V-AMD ή SVM Mode (for AMD)
