What is VMWare?
Asked by Wiki User
VMware is virtulization software. VMware (NYSE: VMW) is the global leader in virtualisation solutions from the desktop to the data center. Customers of all sizes rely on VMware to reduce capital and operating expenses, ensure business continuity, strengthen security and go green. With 2007 revenues of $1.33 billion, more than 120,000 customers and more than 20,000 partners, VMware is one of the fastest-growing public software companies. Headquartered in Palo Alto, California, VMware is majority-owned by EMC Corporation (NYSE: EMC). For more product information http://www.alphacom.co.uk/products/virtualisation/VMware.php
Why might an operating system on a virtual machine run slower than one installed directly on a PC?
Asked by Wiki User
any high end database(datacenter) server, exchange server, any high end appliaction server which require dedicated physical resources will work better on physical then virtual. They will work slow on Virtual servers
What is the relationship between a guest operating system and a host operating system in a system like VMware?
Asked by Wiki User
It is both operating system....
How much memory does it take to run three guest operating systems under vmware server?
Asked by Wiki User
That depends on what operating systems you are trying to run. WIndows Server 2008, for instance, requires a minimum of 512 MB. It is best to never use more than half of the memory available on the computer, so you would need a minimum of 3 GB to run three instances safely.
What is vmotion in vmware terminology?
Asked by Wiki User
Move running virtual machines from one physical server to another with no impact to end users. VMware vMotion keeps your IT environment up and running, giving you unprecedented flexibility and availability to meet the increasing demands of your business and end users
What is the relationship between guest operating system and host operating system?
Asked by Wiki User
These terms are typically only applied in cases where a virtual machine is in use (a computer program that emulates a physical computer), popular examples include VMware, VirtualBox and user-mode Linux. In this case the "host" operating system is running on the physical computer and the "guest" operating system is running in the emulation software.
For example I have a workstation running Debian Linux as a host operating system. When I want to compile a program for several versions of windows I can launch several instances of VirtualBox to bring up virtual machines running Windows XP, Vista and Windows 7 in both 32 and 64 bit versions as guest operating systems. This lets me easily compile the program with optimizations for each of these operating systems using a single workstation and without rebooting.
Virtual machines are also common in web hosting. There are a number of hosting service providers who's business model consists entirely of selling access to user-mode Linux virtual machines. In this case the Linux guest operating system is actually running in a virtual machine under a Linux host operating system, the benefit of using virtual machines is that each customer may be given complete control over their virtual server, while the hosting company can run hundreds or even thousands of virtual servers from a handful of physical computer systems.
How do you deactivate virtual drive?
Asked by Wiki User
You need to click on VM-right click select settings.Then you can either remove the virtual drive permanently or just remove from the machine temporarily.
What is relationship between a guest operating system and a host operating system in a system like VMware?
Asked by Wiki User
A host operating system is the operating system that is in direct communication with the hardware. It has direct hardware access to kernel mode and all of the devices on the physical machine. The guest operating system runs on top of a virtualization layer and all of the physical devices are virtualized. A host operating system should be as modular and thin as possible to allow the virtualization of the hardware to be as close to the physical hardware as possible, and so that dependencies that exist in the host operating don't restrict operation in the guest operating system.
How many virtual networks does VMWare support?
Asked by Wiki User
Technically 10 on VMWare Workstation - VMNet0 to VMNet9. However, VMNet0 is usually used for bridged networking, VMNet1 is usually used for host-only networking, and VMNet8 is usually used for NAT networking, so you actually have only 7 virtual switches for exclusive virtual machine to virtual machine networking. ESX Server may be different, however, as it supports the use of virtual routers and such, making things much more complicated.
How efficient is esx regarding to security?
Asked by Wiki User
ESX is extremely efficient regarding security. Full protection will be achieved once proper procedures are completed. Full requirements must be achieved in order to obtain proper efficiencies.
Where is the best place to get vmware esx?
Asked by Wiki User
It appears that the best place to purchase VMware ESX, along with the rest of the VMware software suite, is the vmware website. There you can purchse the software for immediate download to your computer.
What is advantage and disadvantage of VMware?
Asked by Wiki User
The main advantage is that you don't have to buy two computers, and you don't have to stand up from one computer and walk to the other (or buy a KVM switch). The only disadvantages are that they are really slow, and not quite as stable.
Advantages
- Increase the hardware utilization of your machines
- Decrease capital and operating costs
- High availability
- You can run other programs in a VM that may not necessarily be in the same OS as the host machine (e.g. running Windows or Mac OS X VM on a Linux host machine, and vice versa)
- Some VM solutions allow you to save machine states that will allow you to revert back to a previous state should an error occur
- Generally VMs are somewhat isolated from the host machine in the case of infection by malware, the host will not be affected
Disadvantages
- If the host is down, the VM will be inaccessible
- Increased memory and processor usage as part of overhead introduced by the VM
- With the statement of the VM being "isolated", it also depends on how you configure your machine. If your VM has stuff like shared clipboard/file folders or if there's a feature that allows hardware passthrough (available to a select amount of hardware) it may still expose your host machine to the same threats as if you will with a VM.
