His post focuses on 64 LP support and processor compatibility mode for live migration. Read the post here . Here's an excerpt: 64LP Support We have seen processorsen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.technet.com/virtualization/archive/2009/05/12/hyper-v-in-ws08-r2-release-candidate-bringing-more-to-the-table.aspx#3239556Tue, 12 May 2009 11:28:01 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3239556Gabrie<p>Hi</p> <p>I would like more info on the cpu compatibility mode and abstracting the VM down to the lowest common denominator.</p> <p>Is this common denominator placed on the VM before start of the VM? Or is it more like the lowest cpu off all hosts that is set to be the lowest denominator and all VMs that belong to hosts in that group / cluster?? (I'm used to VMware terminology). </p> <p>If it is host based, what would happen if I remove the lowest host from that cluster, can I just lift the common denominator of that cluster?</p> <p>If it is VM based, would a VM running on host 1 have a different set of instructions when moved to host 2? And how would the OS/Application handle this?</p> <p>Regards</p> <p>Gabrie van Zanten</p> <p><a rel="nofollow" target="_new" href="http://www.GabesVirtualWorld.com">http://www.GabesVirtualWorld.com</a></p>http://blogs.technet.com/virtualization/archive/2009/05/12/hyper-v-in-ws08-r2-release-candidate-bringing-more-to-the-table.aspx#3239583Tue, 12 May 2009 11:57:34 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3239583Site d'information sur Windows Server 2008 R2 et Windows 7<p>Voici 2 &#233;normes nouveaut&#233;s qui arrivent avec la Release Candidate : Support de 64 processeurs logiques</p> http://blogs.technet.com/virtualization/archive/2009/05/12/hyper-v-in-ws08-r2-release-candidate-bringing-more-to-the-table.aspx#3239676Tue, 12 May 2009 15:13:20 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3239676ZenIT Blog<p>Ieri sera si &#232; tenuta la keynote di apertura di TechEd 2009 US, la principale conferenza tecnica annuale</p> http://blogs.technet.com/virtualization/archive/2009/05/12/hyper-v-in-ws08-r2-release-candidate-bringing-more-to-the-table.aspx#3239811Tue, 12 May 2009 17:59:10 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3239811Blog Team TechNet Italia<p>Ieri sera si &#232; tenuta la keynote di apertura di TechEd 2009 US, la principale conferenza tecnica annuale</p> http://blogs.technet.com/virtualization/archive/2009/05/12/hyper-v-in-ws08-r2-release-candidate-bringing-more-to-the-table.aspx#3241768Fri, 15 May 2009 17:09:06 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3241768vinodaswathi<p>I've blogged something about green features Windows Server 2008 R2 has to offer.
