Server Admin I Unit 3 Hyper V Flashcards
Hyper-V (2)
- Microsoft Virtualization Software introduced in Win Server 2008.
- Best practice: install Hyper V as only role on server, create other roles using VMs within Hyper-V
Hyper-V Hardware Requirements (3)
- 64 bit processor with virtualization support
- BIOS that supports virtualization hardware.
- Hardware-enforced Data Execution Prevention(DEP)
Hyper-V New/Updated Features (6)
- Dynamically Expanding Memory
- Smart Paging
- Resource metering
- Resource control.
- Integration Services
- Enhanced Session Mode
Dynamically Expanding Memory (3)
- Allows to specify a range of memory than can be used for each VM.
- Indicate VMs to which extra memory can be allocated
Dynamically Expanding Memory
Startup RAM
memory required to start the virtual machine
Dynamically Expanding Memory
Minimum RAM
min. amount of memory to be assigned to VM
Dynamically Expanding Memory
Maximum RAM
Max amount of memory available to VM
Dynamically Expanding Memory
Memory Buffer
Memory assigned to VM compared to the amt of memory needed by the apps and services running in the VM.
Dynamically Expanding Memory
Memory Weight
Distribution of memory among virtual machines.
Smart Paging (2)
Allows VM to restart when there is not enough available memory.
Smart page is deleted as soon as VM is started
Resource Metering (3)
- Allows tracking of VM stats.
- Enabled using Enable-VMResourceMetering
- Measure-VM : cmdlet monitors usage on VM
Get-VM
Powershell cmdlet that retrieves information about a VM
Resource Control (3)
- Allows analysis of VMs usage of host resources.
- % of total system resources, measured by how many processors are assigned to computer
- Relative weight to determine how CPU resources are distributed between VMs
Integration Services
Drivers that enable guest OS to interact with host and host hardware.
Operating System Shutdown
Integration service that allows for “gracefull” shut down of VM when host reboots.
