Jan 09, 2012  It would by nice, but if you have your network interface of a template on a library server configured as 'Dynamic MAC Address' and you create a virtual machine based on this template, it will get a MAC Address out of the local Hyper-V pool where it has been created on. Hyper-V hosts can also be configured using either the Hyper-V Manager snap-in or Windows PowerShell cmdlets. To view the configuration of a host using the Hyper-V Manager snap-in, right-click on the host in the console tree and select Hyper-V Settings to display the Hyper-V Settings dialog box shown in the screen shots in this section.

Jan 18, 2013  The first three octets (aa-bb-cc) are Microsoft's IEEE organizationally Unique Identifier, 00:15:5D (which is common on all Hyper-V hosts. The next two octets (dd-ee) are derived from the last two octets of the server's IP address. The last octet (ff) is automatically generated from the range 0x0-0xFF. What I need to know is what range of MAC addresses can I use without fear that one day some device may be connected to our network with that MAC? I have read the Wikipedia article on MAC addresses and this section seems to indicate that if I create an address with the form 02-XX-XX-XX-XX-XX then it is considered a locally administered address.

This article provides information about System Center - Virtual Machine Manager (VMM) default MAC addresses, and describes how to create and manage a custom MAC address pool.

VMM uses static MAC address pools to automatically generate and assign MAC address to VMs. This article describes default MAC address pools in the VMM fabric and explains how to create custom pools.

Default MAC address pool settings:

Before you start

Before you create a custom MAC pool note that:

• If you want to divide one of the default pools into smaller custom pools, you must first delete the default MAC address pool or the default VMware MAC address pool. You must delete the default pool to avoid duplicate MAC address assignments.
• The first three octets of the beginning and ending MAC address must be the same.
• You must enter a valid hexadecimal values between 00 and FF.
• The ranges that you specify cannot overlap.
• The address range must not have the multi-cast bit set to 1. For example, you cannot use addresses that start with X1, X3, X5, X7, X9, XB, XD, or XF, where X is any value.
• To avoid conflicts with addresses reserved by Microsoft, VMware, and Citrix, do not use the following prefixes:
  • Reserved for Microsoft: 00:03:FF; 00:0D:3A; 00:12:5A; 00:15:5D; 00:17:FA; 00:50:F2; 00:1D:D8 (except for the 00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF range that is reserved for VMM)
  • Reserved for VMware: 00:05:69; 00:0C:29; 00:1C:14; 00:50:56 (except for the 00:50:56:00:00:00 – 00:50:56:3F:FF:FF range that is the reserved as the default VMware static range)

Create a custom pool

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources > Create > Create MAC Pool.
2. In Create MAC Address Pool Wizard > Name and Host Group specify a name and description. In Host Group select the host groups that should use the pool.
3. In MAC Address Range specify the start and end addresses.
4. In Summary review the settings and click Finish. When the job shows as Completed verify pool in MAC Pools.

Release IP addresses

In some circumstances you might want to remove addresses from the MAC pool. For example if a host that was assigned an IP address during bare metal deployment is removed from VMM management, or if a VM goes into a missing state because it was removed outside VMM.

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources.
2. In MAC Pools click the pool you want to modify > Properties.
3. In Inactive addresses select the addresses you want to release.

Syntax

Description

The Set-VMHost cmdlet configures a Hyper-V host.

Examples

Example 1

This example configures the local Hyper-V host to allow 10 simultaneous live migrations and storage migrations.

Example 2

This example configures a range of MAC addresses range for the local Hyper-V host.

Example 3

This example enables the use of any network for incoming live migrations on the local Hyper-V host.

Example 4

This example specifies new default locations for virtual hard disksand virtual machines on the local Hyper-V host.

Example 5

This example configures Fibre Channel host settings on the local Hyper-V host.

Example 6

This example disables NUMA spanning on the local Hyper-V host.

Ip Address

Example 7

This example configures the local Hyper-V host to save data that tracks resource consumption every hour and a half.

Example 8

Our team has led many innovations in the software industry and ProjectLibre is being used in over 200 countries.The project management domain complexity is tremendous. There are many universities now offering Masters and PhD programs in project management. Open source microsoft project for mac. The ProjectLibre team will also be releasing a cloud version, allowing project teams to effectively work together regardless of location, and a Portfolio Project Management solution is also in the works.We interviewed Marc O'Brien, co-founder of ProjectLibre, to find out how they plan to edge their way into the market.Q: A good open source project management solution is hard to find, why is that?A: It is highly complex both in the code and domain expertise.ProjectLibre was created by a team that has been for a significant time. This encompasses not just the critical path scheduling but resource management, earned value costing, variance analysis, and significant complexity in both managing and controlling a project. Is an open source project management solution ready to give Microsoft Project a run for their money.In late summer, there will be a new version of the Open Services Gateway Initiative (OSGI) modular architecture that will allow connector modules for better integration with enterprise solutions.

The example configures the local Hyper-V host to use Kerberos to authenticate incoming live migrations.

Parameters

Runs the cmdlet in a remote session or on a remote computer.Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet.The default is the current session on the local computer.
