Cloud hypervisors are also popularly known as virtual machine managers. These hypervisors are critical to cloud architecture and allow hosting providers to run numerous operating systems on a single server. Hypervisors are most important part in cloud computing. These virtual machine managers are considered to be one of the more secure components as well. So, most of the enterprises have started opting for cloud technology to avail cloud hypervisors for complete security and running numerous business applications.    

According to technical experts future hypervisor flaws and subsequent forced cloud provider reboots are likely, and perhaps predictable. The main problem is that there are several public cloud services which are not supportive to live migration and allow the movement of a virtual machine from one physical host server to another and it never goes offline also.      

There are several comprehensive perceptions about hypervisors that these are more secure than any other available software in the industry. It is one of the myths that users think hypervisors are secure and that is not the case all the time. 

According to a survey it has been proved that the enterprises create their cloud hosting architecture more secure and fault-tolerant. These practices are considered as running instances in two or more availability zones. The organizations use auto scaling and ensure a set number of examples. According to some technical professionals enterprises and vendors should monitor their hypervisors to ensure that they are properly patched and updated. If they do the same, they will avoid any security issues and can secure their data at first place.
