If the page size is 8kb, then 14 bits of the virtual address are used for the final offset. That leaves (48-14) or 34 bits to select the page table entry. That is 17,179,869,184 entries in a maximally filled page table. The physical address size has no bearing to this particular question, because you asked how many entries, not how large the page table would be.
Know the usage to understand if it is virtual machine or a physical machine.
Real memory uses Physical addresses.These are the members that the memory chips react to on the bus. Virtual addresses are the logical addresses that nrefer to a process' address space. Thus, a machine with a 16-bit word can generate virtual addresses upto 64K, regardless of whether the machine has more or less memory than 64 KB
The performance of a virtual machine is much faster compare to that of a physical machine. You can read more information at en.wikipedia.org/wiki/Virtual_machine
A 'virtual machine' is a software program which emulates another machine type. The virtual machine behaves exactly like the machine it emulates but uses the physical hardware of the machine it is running on. In other words, it translates calls intended for the virtual machine into calls that will execute upon the physical machine, effectively acting as an interpreter between the two machines.

The concept of a logical address space is simply involved the process of mapping the Logical addresses to their Physical Addresses . Logical addresses are generated by the CPU; also referred to as virtual addresses.while Physical Address is the actual address of the data stored on the physical device and mapped by MMU.
Installing Server 2008 in a virtual machine is really no different than installing in a physical box; you boot the install DVD in the virtual machine and follow the prompts the same way as booting from the DVD on a real, physical machine.

Physical-to-Virtual, also known as "P2V", describes the process of decoupling and migrating a physical server's operating system, applications, and data from a physical server to a virtual machine guest hosted on a virtualized platform.
Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture
This is usually called emulation.
If your Virtual Machine freezes or becomes unresponsive you can restart the Virtual Machine by doing what?
