Hyper V Flashcards
Powershell Direct
Uses VM bus layer
No network layer needed
Must be on Host to connect to VM
Enable Nested Virtualization PS
Set-VMProcessor
NUMA
Memory regions directly access by the CPU
Low latency & High Speed
Smart paging
Use of disk space when there is memory pressure on the host
On restarts of the VM
Dynamic Memory
Must be disabled when allocating memory to a VM.
Enhanced session mode
RDP capabilities using the VM bus
Configure Secure Boot using PS
Set-VMFirmware
Direct Device Assignment (DDA)
PCIe pass thru to VMs
Hardware to be disabled on Host first
Update VM
Update-VMVersion
Resource metering for VHDs
Set Max and Min IOPS for a virtual disk
Differencing Disk
Parent - Child Disk relationships
Saves on storage space

Types of Checkpoints
Production and Standard
Production Checkpoint
Point in time image that can be restored later
Uses VSS
Use in production environment
Standard Ceckpoint
Captures state, data and hardware configuration
Testing & Troubleshooting
Command to view checkpoints
Get-VMSnapshot
Virtual Switch Types
Internal, External & Private
Internal Switch
VMs communicate with VMs & the Host
External Switch
VM commuicate with each other and the Hosts physical network. Uses SR-IOV
Private switch
VMs only communicate with VMs
VM MAC Address
Needed to communicate at Layer 2
Dynamic & Static MAC addressing
Virtual Machine Queues
Packets stored on physical NIC which a password directly to the VM
SR-IOV
Virtualization of physical NIC.
Bypasses to Hypervisor layer straight to the VM
Increase performance
SR-IOV PS command
Enable-NetAdapterVMQ
NIC Teaming
Forms a team out of 2 or more NICs
NIC Teaming properties
Bandwidth aggregation
Load balancing
Fault tolerance
NIC Teaming Modes
Switch Independent
Static Teaming
LACP
Load balancing modes
Address Hash
Hyper-V Port
Dynamic
RDMA
Data exchanged directly with application memory
Increased performance
Bypassing buffers on the OS.
SET (Switch embedded teaming)
Physical Switch unaware of virtual NIC team
No role in the NIC teams distribution of traffic
Members of a SET
Identical Network adapters (Model, Drivers, Manufacturer)
Network Controller
Server Role
Manage, configure and monitor the virtual and physical network.
PS Command for RDMA
Enable-NetAdapterRDMA
Modify Memory on Active VM
Set-SCVirtualMachine
Assign / Replace adapters on a team
