Network requirements for Microsoft Hyper-V Cluster

In this post describe physical networks configuration for hyper-v cluster. The below table shows minimum requirements for network in a Hyper-V cluster. Generally, two NIC with eight ports is require to configure hyper-v cluster networks with Teaming ( Network high availability )

Hyper-V Networks Description Type
Management Used for the Remote desktop, monitoring, backup, and Hyper-V management traffic all pass through this network by default. Public
VM Network Used to provide network access for VM’s .All VM’s network traffic will pass through this network Public
Cluster Heartbeat Private network to check the status of the cluster hosts Private
Live Migration Used to transfer the running VM’s from one cluster node to another Private

Other Recommendations

Dedicate VLAN for each networks

Network teaming is recommended for all networks . So two NIC with eight ports is required. In addition more VM’s network can be added based on the through-put and networks requirements such as DMZ,..Etc

Management networks should be first i in the Adapter and Bindings connection order. Then heartbeat and failover network .

Do not configure a Gateway and DNS for Heartbeat and failover networks.

Disable file and print sharing for VM networks and not require to set IP’s

Note : The storage networks will be cover in another post.

Must have at least 512 MB of RAM

Cannot have any volumes larger than 2040 GB.

Must have an Advanced Configuration and Power Interface (ACPI) BIOS – Vista WinPE will not install on a non-ACPI BIOS.

Must be accessible by VMM and by the host computer.

Please refer below link for supported server operating systems https://seneej.com/2013/07/13/scvmm-2012-supported-operating-systems-for-p2v-conversion-2/

Online conversion Step by Step using SCVMM

SCVMM 2012 SP1 Host Agent Manual installation and Client logs

In this post, we will discuss SCVMM agent manual installation and troubleshooting client installation

Where SCVMM Server Setup Logs located ?

SCVMM agent installation logs located under hidden folder C:ProgramDataVMMLogs on windows server 2008 R2 and 2012.

In some cases, the agent push or GUI installation is failed and logging doesn’t provide information to find cause of failure. In this scenario you may start manual agent installation with logging as below:

msiexec /I <MSIPackageName.msi> /L*V<pathlogfilename>.log

Host agent can find the installation files on SCVMM server: c:programfilessystem center 2012scvmmagentamd64version x.x.xxx and msi files

Host Agent manual installation example :
