Cisco Services Ready Engine Virtualization (Cisco SRE-V) is a branch-office infrastructure platform that combines computing, networking, storage access, virtualization, and unified management into a cohesive system. It enables the VMware vSphere Hypervisor to be provisioned on a Cisco Services Ready Engine (SRE) Service Module and to host one or multiple virtual machines running the Microsoft Windows Server or Linux operating systems. The entire system is integrated with the Generation 2 of the Cisco Integrated Services Router (ISR G2).
This document provides system requirements, information about open source software, new and changed information, and open and resolved caveats for Cisco Services Ready Engine Virtualization Release 2.x.
Some components of the software created for Cisco Services Ready Virtualization are provided through open source or commercial licensing. For more information about these components and associated copyright statements, see http://www.cisco.com/en/US/products/ps11273/products_licensing_information_listing.html
- Added new procedure to migrate the Cisco SRE-V software from release 2.0.1 to release 2.x. See Migrating the Cisco SRE-V Software from Release 2.0.1 to Release 2.x.
- As of October 2013, added support for VMware ESXi 5.1 on the Cisco SRE 710 and 910 modules.
- Added support for VMware ESXi 5.0 on the Cisco SRE 710 and 910 modules.
- Added the ability for the Cisco SRE-V host to shut down gracefully when the reset button on the front panel is pressed. This also shuts down the virtual machines. (You can configure a graceful shutdown for virtual machines through the vSphere Client or vCenter Server.)
- Achieved Microsoft SVVP certification for the Cisco SRE-V Release 2.0 software for Microsoft Windows Server 2008 R2.

Table 1 lists the caveats that are open in Cisco SRE-V Release 2.x.
Conditions: Install the Cisco SRE-V software through the helper. Delete a datastore, and try to add it back to the ESXi host using the VMware vCenter Server. The datastore addition is unsuccessful and displays the following error:
This is a limitation of ESXi when dealing with a local datastore. More information can be found in this KB article called “Creating a local VMFS volume generates the error. Error during the configuration of the host. Failed to update the disk partition information” at http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1001489
Workaround: From the vmkernel.log you can see that it displays an error that says “partition 1 modification is not supported”, which is addressed in the KB article. The workaround is to use the command line tools as VMware specified in the KB article.
Table 2 lists the caveat that was resolved in Cisco SRE-V Release 2.0.
