You can move a VM from host A to host B with no noticeable downtime .. it\u2019s just a few milliseconds, less than any network protocol will notice.<\/li>\n<li>Processor compatibility mode allows VM\u2019s to migrate between hosts with physical processors of different generations.\u00a0 You\u2019re still bounded to either all AMD or all Intel.\u00a0 That\u2019s done by tuning back functionality.<\/li>\n<li>With other W2008 R2 functionality you get a all MS VDI solution.<\/li>\n<li>A new version of Hyper-V Server 2008 R2 with CSV and Live Migration support.<\/li>\n<li>If you do want to go Core Installation then there\u2019s the SCONFIG tool to rapidly configure the host.<\/li>\n<\/ul>\n<p>Coming soon?<\/p>\n<ul>\n<li>Microsoft released 20,000 lines of GPLv2 licensed code to update the kernel of Linux distributions.\u00a0 If all goes well, all future Linux distros will be Hyper-V enlightened out of the box.<\/li>\n<li>There is a new version of VMM 2008 R2 coming.\u00a0 It will offer support for all of\u00a0the new Hyper-V features.\u00a0 It also brings in Quick Storage Migration to quickly move VM&#8217;s from one location to another with minimum downtime, e.g. move a VM from a per-LUN installation to CSV with 1 minute downtime VS 1 hour.\u00a0 There&#8217;s also a new maintenance mode for hosts and some cool SAN integration.<\/li>\n<\/ul>\n<div style=\"padding-bottom:0px;margin:0px;padding-left:0px;padding-right:0px;display:inline;float:none;padding-top:0px\">Technorati Tags: <a href=\"http:\/\/technorati.com\/tags\/Windows+Server+2008+R2\" rel=\"tag\">Windows Server 2008 R2<\/a>,<a href=\"http:\/\/technorati.com\/tags\/Hyper-V\" rel=\"tag\">Hyper-V<\/a>,<a href=\"http:\/\/technorati.com\/tags\/Virtualisation\" rel=\"tag\">Virtualisation<\/a>,<a href=\"http:\/\/technorati.com\/tags\/Live+Migration\" rel=\"tag\">Live Migration<\/a>,<a href=\"http:\/\/technorati.com\/tags\/VMM\" rel=\"tag\">VMM<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>I\u2019ve done nothing but talk about this since last October when details first started to get out from Redmond \ud83d\ude42\u00a0 I\u2019ve done a number of presentations including this one at PubForum recently.
