Cisco is collaborating with Microsoft to bring its virtual switch to Hyper-V next year when Windows Server 8 is released. While Cisco’s Nexus 1000V distributed virtual switch already supports VMware software, Hyper-V in Windows Server 2008 R2 does not get the same love. The new support for Hyper-V will only apply to the forthcoming Windows Server 8, which introduces greater ability to integrate third-party modules than its predecessor, according to Cisco.
