Our MAC Address API outputs a field called macAddressDetails.virtualMachine. If it detects that a Virtual Machine is using this MAC address, it outputs its vendor name (e.g. ”VMWare”). Otherwise, it outputs “Not detected”.
Luckily, there is a Debian-based operating system that is configured beautifully — especially for those leaving Microsoft’s OS. Called “Netrunner Desktop,” it comes pre-loaded with many useful programs, making it an absolute joy to use. Today, it reaches version 17.03, code-named “Cyclotron.” Red Hat Family. Red Hat to ramp up headcount. Alternatively, review the outputted information and MAC addresses from the command esxcfg-nics -l. Method -2 – DHCP Server. Another way to find the Mac address is from the DHCP Server, Go to the Scope – Address Lease, It will list all the IPs with the Mac address but it will help only for the DHCP IPs and not for the static address. I tried this in VS.net and it gave me the following error: D: VisualStudio Interface.cs(10): Interfaces cannot contain fields Tech Interviews comment by Kiran Mandhadi 21. #12 The.Net compiler does not accept a virtual private method which makes sense since a virtual private method makes no sense.

To detect the Virtual Machines, we build our VM Knowledge Base, which stores information about known relations between MAC addresses and Virtual Machines, and patterns, based on which the Virtual Machines assign MAC addresses to the virtual network interfaces.
This information comes from the two sources:
- We constantly scan the Internet for such information. It’s systemized, stored and verified.
- Our research team installed the Virtual Machines and performed experiments, trying to identify patterns on how their network interfaces receive MAC addresses.

More questions
After you set a certain static MAC address to a virtual machine adapter, you cannot power on the virtual machine.
In the vSphere Web Client, after you assign a MAC address within the range 00:50:56:40:YY:ZZ – 00:50:56:7F:YY:ZZ to a virtual machine, attempts to power the virtual machine on fail with a status message that the MAC address is in conflict.
03.code Combatmr. Mac's Virtual Existence Meaning
Cause
You attempt to assign a MAC address which starts with the VMware OUI 00:50:56 and is within the address range allocated for host VMkernel adapters on the vCenter Server system.
If you want to preserve the VMware OUI prefix, set a static MAC address within the range 00:50:56:00:00:00 – 00:50:56:3F:FF:FF. Otherwise, set an arbitrary MAC address whose prefix is different from the VMware OUI one. For information about the ranges available for static MAC addresses that have the VMware OUI prefix, see the vSphere Networking documentation.
