Release Notes for Cisco Services Ready Engine Virtualization Release 2.0
December 9, 2011
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 2.0.
Open Source Software Information
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
Cisco SRE-V Release 2.0 supports the following new features:
•Added support for VMware ESXi 5.0 on the Cisco SRE 700, 710, 900, 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 2.0.

Bug ID Summary Additional Information
DCUI blackout with ESXi5.0
Symptom: DCUI blackout with ESXi5.0.
Conditions: The DCUI screen is not displayed after reloading the router. A separate telnet session does not help either. This problem occurs occasionally, usually after a router reload.
Root cause: The hard-coded hardware flow control in SM PSE2 FPGA blocks DCUI characters and causes ESXi to permanently drop the serial port before reboot.
Workaround: Reload or reset the module to reboot ESXi.
Cannot add deleted datastore
Symptom: Cannot add a deleted datastore.
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:
Call "HostDatastoreSystem.CreateVmfsDatastore" for object "datastoreSystem-46" on vcenter server "WIN-ORCICT4IIH8" failed.
This error occurs when the following steps are used:
1. You install Cisco SRE-V software through the helper.
2. You shut down the VMware vCenter Server and remove it from the VMware vCenter Server inventory.
3. You delete the datastore.
4. You add the datastore using the Add Storage wizard.
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.
