I have a server at my company with Windows Server 2008 R2 with 4 VM's for software testing.

1st Question I have access to the new Windows Server 2012. Is HyperV in Server 2012 much better than the one in Server 2008 R2? Or the advantages are more for Data Centers?

2nd Question With Windows Server Standard I can only have 4 virtual machines running or I can only have 4 virtual machines sharing the host key? Can I have more than 4 VM's with Server Standard Edition or I need a Data Center Edition to have 6-8 VM's?

Thsnks.

  • CSeven, welcome to ServerFault. Note that both your questions are either considered "not constructive" or "off-topic" here so your question is likely to be closed at short notice. As this is a Q&A site, questions have to be objectively answerable, where an *"is A better than B"* question simply can't fit. Also, questions regarding licensing are explicitly considered off-topic as per the [FAQ](http://www.serverfault.com/faq) to avoid the possibility of wrong advice. – the-wabbit Apr 15 '13 at 10:01
  • Hi. I don't want to know if HyperV is better than VMWare or other software's out there. I just want to know if the new version has significant improvements from the previous version, and in the scenario of installing a new HyperV Server the 2012 version is the best option. Based on facts you can be objective comparing two versions of a software. Regarding question 2, I already have the license of the product and don't have questions about that. I only wanted to know if I could have more than 4 VM's on a Server Standard, or if that is only possible with the Data Center Edition. Thanks :) – CSeven Apr 15 '13 at 11:35

Regarding your first question I would refer you to the official feature comparison between Hyper-V in 2008R2 and 2012 as published on the Microsoft web site.

Regarding the second question: there is no technical limitation to 4 or 6 virtual machines per host. You will be bound by a hard limit of 1,024 running VMs per host though. You might be aiming at the licensing terms allowing to run Windows VMs as guests, but licensing questions are explicitly off-topic here. Refer to the information published by Microsoft on this topic and ask your software dealer for advice when in doubt.

For Question 2: Server 2012 Standard allow you to run 2 virtual S2012 servers on the host server 2012. That gives you 1 server and 2 virtual with one key. If you want more, you indeed need the datacenter edition. You can however run more than 2 VM machines on 1 s2012 standard.

    Ok. So, if I have keys for all the VM's I can have the number of VM's I want on a Windows Server Standard Edition? Thanks ;) – CSeven Apr 15 '13 at 11:39
