Troubleshooting quick list

• No disk visible: load virtio storage driver from virtio ISO in installer.
• Slow disk/network: ensure virtio drivers installed in guest; check host CPU steal; use io='native' and cache='none'.
• Activation issues: confirm license type (Retail/OEM/VL) and key.
• Mouse/keyboard not synchronized: enable USB tablet, install Spice/guest additions.
