what is the difference between full virtualization and para virtualization?
148937
The main difference between full virtualization and paravirtualization in Cloud is that full virtualization allows multiple guest operating systems to execute on a host operating system independently while paravirtualization allows multiple guest operating systems to run on host operating systems while communicating ...

A virtual machine (VM) is a software computer used as emulation of an actual physical computer. A virtual server operates in a “multi-tenant” environment, meaning that multiple VMs run on the same physical hardware. ... A hypervisor is then used to create and manage VMs, which have their own virtual computing resources.

Virtualization can make 1 resource act like many, while cloud computing lets different departments (through private cloud) or companies (through a public cloud) access a single pool of automatically provisioned resources.

Virtualization has three characteristics that make it ideal for cloud computing: Partitioning: In virtualization, many applications and operating systems (OSes) are supported in a single physical system by partitioning (separating) the available resources.

Containers. Unlike virtual machines where hypervisor divides physical hardware into parts, Containers are like normal operating system processes. ... Namespaces is an advance concept in linux where each namespace has its own isolated resources without actual partitioning of the underlying hardware.

While grid computing involves virtualizing computing resources to store massive amounts of data, whereas cloud computing is where an application doesn't access resources directly, rather it accesses them through a service over the internet. ...

A virtual machine (VM) is a software computer used as emulation of an actual physical computer. ... The architecture of a virtual server is a little more complex than that of a physical server. Thus, a hypervisor, such as VMware vSphere or Microsoft Hyper-V, is installed on top of physical hardware.

Do you need Intel VT-x or AMD-V based CPU to run Virtual Machines? The answer is both Yes and No. Intel VT-x or AMD-V capable processors have inbuilt set of processor instruction that can handle virtualization effectively. To be able to use these instruction, they need to be enabled in BIOS.

Hyper-V is Windows Server Virtualization Platform, it's a TYPE 1 hypervisor. ... The company - VMware features ESXi as its virtualization tool that can manage single/multiple hosts and turn it into a cloud computing enabled environment. On the other hand, hyperV is the Microsoft's product similar to VMware's ESXi.

With thick provisioning, only two users could fit on the drive. ... Also known as virtual provisioning or thin storage, thin provisioning is the rival disk provisioning method. Thin provisioning allocates disk space to users on demand based on how much space they need at any given time.

As to what the actual difference is between those two options - well that could go on to be a very long answer but essentially LVM deals with extents and has multiple additional layers of abstraction that clearly need to be considered during boot - whereas the standard Linux PT should be a lot more starightforward than ...
