Virtual Switch |
simulates a Layer 2 physical switch.
|
|
|
A hyper-v virtual switch can have ____ ports
|
Unlimited
|
|
|
When you create an external nework virtual switch what changes on the host machine?
|
"A new ""network adapter"" is added described as a switch. The physical network adapter is bound to the second new adapter."
|
|
|
External network switch
|
virtual switch in hyper-v that's connected to the outside of the host machine. -- Connected to the broader network
|
|
|
Internal Network Switch
|
A virtual switch that connects VMs together and with their host partition.
|
|
|
Private network switch
|
A virtual switch that only connects child partitions / VMs together. The host machine cannot access the VMs.
|
|
|
MAC
|
Media Access Control
|
|
|
Length of a MAC address
|
6 bytes (48 bits). First 3 bytes is the OUI (organizationally unique ID). Last 3 bytes IDs the adapter.
|
|
|
What is the Microsoft OUI?
|
00-15-5D
|
|
|
What is the pattern of a hyper-v VM MAC address?
|
Bytes 1-3 = The MS OUIBytes 4-5 = Last two bytes of the IP in hexByte 6 = Assigned hex between 00 and FF (256 possibilities)
|
|
|
How many virtual network adapters can you attach to a hyper-v VM
|
12: 8 synthetic4 emulated
|
|
|
Synthetic Adapter
|
Default & best type of network adapter. Communicates via VMBus instead of through the hypervisor which allows for faster communications
|
|
|
VMBus
|
High-speed conduit that allows virtual devices to communicate with the parent partition without going through the hypervisor.
|
|
|
Virtual Switches reside where?
|
On the parent partition of the hypervisor
|
|
|
Synthetic Adapters depend on what to run?
|
The guest integration services package. A VM without this installed cannot communicate using a synthetic adapter
|
|
|
Emulated adapter AKA
|
Legacy Adapter
|
|
|
Emulated adapter
|
Standard network adapter driver that communicates with the parent partition directly via the hypervisor. This requires requests to filter down through the TCP/IP stack of the guest to the hypervisor back up to the parent's application layer and down through its TCP/IP stack. So slower...
|
|
|
Why would you use an emulated adapter?
|
To boot in a PXE environmentor if your guest OS isn't running a guest integration services package
|
|
|
PXE
|
Preboot eXecution Environment.Used to deploy an OS on machine boot |
