CentOS 7 converts Linux system to virtual machine via DD

I.. configuring a KVM Server

1. Configure Virtio Source

wget Https://fedorapeople.org/groups/virt/virtio-win/virtio-win.repo-O/etc/yum.repos.d/virtio-win.repo

Iv. Known Issues:

DD mode can be any system to do disk mirroring, but because Windows system does not have IDE, Virtio and other hard disk drive, cause the Windows image of DD out in IDE mode to boot in the KVM will also cause blue screen.
