Virtualization has become a widely and attractive employed technology in cloud computing environments. Sharing of a single physical machine between multiple isolated virtual machines leading to a more optimized hardware usage, as well as make the migration and management of a virtual system more efficiently than its physical counterpart. Virtualization is a fundamental technology in a cloud environment. However, the presence of an additional abstraction layer among software and hardware causes new security issues. Security issues related to virtualization technology have become a significant concern for organizations due to arising some new security challenges. The report discusses the major challenges and risks associated with virtualization of cloud environments. It also concentrates on certain specific cyber challenges and attacks that impact cloud protection. The survey analyzed cloud stakeholders ' views on virtualization weaknesses, risks and solutions to resolve these vulnerabilities.
