Top 5 Microsoft Hyper-V Network Virtualization Q&A
The top 5 Hyper-V questions with answers provided by Nirmal Sharma, a MCSEx3, MCITP and Microsoft MVP in Directory Services.
Microsoft Hyper-V Network Virtualization (HNV) enables hosting providers to host customer virtual machines (VMs) without requiring any changes to the physical network topology. Customers can bring their own IP address and network topologies and easily move enterprise services to a shared IaaS cloud.
HNV Questions and Answers
Courtesy of ServerWatch, here are the top 5 Hyper-V questions with answers provided by Nirmal Sharma, a MCSEx3, MCITP and Microsoft MVP in Directory Services.
Q. What are all the configuration approaches available with Hyper-V Network Virtualization?
A. Two: NVGRE and IP Rewrite.
Q. What is the mechanism used by NVGRE?
A. NVGRE uses the GRE mechanism to encapsulate and de-capsulate methods. You can take a closer look at the NVGRE protocol draft here: http://tools.ietf.org/html/draft-sridharan-virtualization-nvgre-00
Q. Can virtual machines talk to outside networks?
A. No, this is what HNV is lacking at the moment. Virtual Machines participating in Hyper-V Network Virtualization cannot access the Internet or an outside network unless you implement a forwarding agent. Forwarding agents such as CISCO Nexus 1000v or an NVGRE gateway must be implemented in order to allow virtual machines to access the Internet or enterprise premises networks.
Q. Does HNV virtualize Host IP also?
A. No, HNV only virtualizes CA IP Addresses.
Q. Does PA Address need to be routable across the datacenter network?
A. Yes, PA Address must be routable and unique across the datacenter network. In other words, PAs communicate with each other, so they must be unique on the physical network.
