Gen 2 vm’s allow PXE booting from std nic

2013/08/04 | By | Reply More

A great new feature in Windows Server 2012 R2  is the ability to create Generation 2 vm’s.

Generation 2 vm’s support PXE booting using the standard nic.  Unfortunately it only applies to Server 2012 and 64bit Windows 8 or higher systems only

For anyone who has ever pxe booted into a mounted capture boot iso using the legacy pxe nic the image creation would take an extremely long time since copying the image to your network share would be limited to the legacy adapter 100 Mbps speed. So a copy process which might normally take 30 minutes on a 1Gbps network would end up taking 300 minutes. Ouch!!

Thankfully, with Windows Server 2012 R2 Generation 2 vm’s image creation at least of Server 2012 and 64bit Windows 8 or higher will be at the speeds of your standard nic up to 10 Gbps. This will greatly reduce the creation time.
