The virtualization technology brings the convenient conditions to the cloud computing, but new security challenges are introduced. The paper made the in-depth research on the related documents and reality. The existing status of the virtualization security including virtual machine sprawl, peculiar set-up hidden, virtual machine hopping, virtual machine escape and denial of service attack, is analyzed from the hidden dangers and the attacks. The practical method of the virtualization security is proposed from three aspects including the security mechanisms of host, Hypervisor and VM. The security technical support is provided for the infrastructure platform.
