Fidelity
The environment it creates for the VM is essentially identical to the original (hardware) physical machine.
100
partitions
rather than guests virtual workloads are called
100
consolidation
practice of taking existing physical servers and converting them into virtual servers that can run atop the hypervisor
100
package
contains an application suite or a set of functionality to be installed
100
clustering
for increased performance and ability
200
Isolation or Safety
The VMM must have complete control of the system resources
200
rings
protection in the form of levels
200
hot cloning
as the name inplies performs the clone operation while the source server is booted and the application is running
200
contention
resources that are constrained
200
pages
memory blocks
300
Performance
There should be little or no difference in performance between the VM and a physical equivalent.
300
child disk
changes to a snapshot go to this
300
hot cloning
performs the clone operation while the source center is booted and the application is running
300
CPU
computer inside a computer
300
ballooning
reclaim memory back from the virtual machine
400
data center
could be anything from large room to a whole building containing data.
400
virtual appliance
can represent a range of virtual machine deployments depending on who is doing the defining
400
templates
virtual machines that already contain an operating system and often are already loaded with application software as well
400
core
processors inside the cpu
400
memory overcommitment
the ability to allocate more virtual memory on a host than physically exists
500
lost server
a server that is running but no one actually knows which line of business owns it or what it is doing.
500
containment
is the practice of initially deploying new aplication workloads as virtual machines so additional physical servers will not be required.
500
daemons
automatically started as part of the operating system boot
500
hyper threading
intel microprocessor technology that improves performance by making more efficiant use of the processor scheduling
500
page sharing
technique that storage venders use to reduce data blocks
