In this video, I perform a number of Live Migrations, for the different VM types (VHD, Pass Through Disk and CSV), includingen-GBTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.technet.com/b/mattmcspirit/archive/2009/05/22/virtualboytv-com-hyper-v-r2-failover-live-migration.aspx#3261462Mon, 06 Jul 2009 13:48:17 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3261462MattMcSpirit<p>Hi Martin,</p> <p>When you are just using pure Hyper-V, and no System Center, the failover is based on logic. &nbsp;You can read all about that here: <a rel="nofollow" target="_new" href="http://blogs.technet.com/mattmcspirit/archive/2009/02/03/hyper-v-clustering-virtual-machine-failover-behaviour.aspx">http://blogs.technet.com/mattmcspirit/archive/2009/02/03/hyper-v-clustering-virtual-machine-failover-behaviour.aspx</a> but if you involve System Center, i.e SCOM and SCVMM, I believe that there is more intelligence involved, but I'd have to look into that one for sure! &nbsp;The link above talks about 2008, and there has been improvements in R2, but I believe it's still logic-based out of the box.</p> <p>Hope that helps!</p> <p>Matt</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3261462" width="1" height="1">http://blogs.technet.com/b/mattmcspirit/archive/2009/05/22/virtualboytv-com-hyper-v-r2-failover-live-migration.aspx#3261123Fri, 03 Jul 2009 22:41:59 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3261123Martin<p>Hi Matt</p> <p>In this video you have 2 nodes... Let's say you had 6 nodes and 1 node failed, crashed etc. How would the VM's failover in a 6 node setup?</p><div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3261123" width="1" height="1">
