Installing Cisco vWAAS on RHEL KVM in Cisco WAAS Version 5.x to 6.2.x
Using the Launch Script to Deploy Cisco vWAAS on RHEL KVM in WAAS Version 5.x to 6.2.x
To use the launch script (launch.sh) to deploy Cisco vWAAS on RHEL KVM, follow these steps:
Step 1 Launch the Cisco vWAAS VM. (You must have root permissions to launch the Cisco vWAAS VM.)
Step 2 Create a new directory to hold the extracted contents of tar.gz.
Step 3 Copy tar.gz into the specified directory.
Step 4 To extract the tar.gz gzip file, use this command:
tar -zxvf Cisco-KVM-vWAAS-ModelNumber-Version-BuildNumber.tar.gz
tar -zxvf Cisco-KVM-vWAAS-200-6.2.3d.b-68.tar.gz
The contents of the tar.gz file are:
Step 5 To launch Cisco vWAAS, run the launch.sh script:
- To check the prerequisite conditions, use the /launch.sh check command.
- To launch Cisco vWAAS using the OVS bridge, use the./launch.sh vm-name bridge bridge1-name bridge2-name command.
– bridge1-name and bridge2-name: The OVS bridges already created in the host.
Note Before using the /launch.sh vm-name bridge bridge1-name bridge2-name command, verify that the OVS bridges are created and are in working state.
- To launch Cisco vWAAS using macvtap, use the /launch.sh vm-name macvtap interface1-name interface2-name command.
– vm-name: The specified name of the Cisco vWAAS VM.
– interface1-name and interface2-name: The specified Ethernet interfaces of the host machine.
1. Use the virsh undefine vm-name command.
2. Remove the directory with the specified vm-name.
Note If you want to create another Cisco vWAAS of the same model, repeat this procedure. The specified directory, for example, Basic, will then have two VMs, Basic1 and Basic2. Disks for these VMs will be stored in the subdirectories Basic1 and Basic2, respectively.
Using the EzDeploy Script to Deploy Cisco vWAAS on RHEL KVM on Cisco UCS-E in WAAS Version 5.x to 6.2.x
Use the EzDeploy script for simplified deployment of a Cisco vWAAS. Note that the EzDeploy script is not used for the Cisco vCM.
The following are the prerequisites for launching the EzDeploy script:
- To launch the Cisco vWAAS VM, you must have root permission.
- The following software and utility packages must be installed before using the EzDeploy script:
– Expect script (required only if you choose to run EzDeploy’s capability for auto-monitoring Cisco WAAS Central Manager registration status)
– There is sufficient disk and RAM memory to deploy another Cisco vWAAS.
– Compatibility of software versions.
– Availability and readiness of network connectivity.
Note Because EzDeploy leverages the launch.sh script to launch a Cisco vWAAS, the launch.sh script, as well as all the necessary files associated with it, must be present, intact, and not manually removed or manually moved elsewhere.
To use the EzDeploy script (ezdeploy.sh) to deploy Cisco vWAAS on RHEL KVM on Cisco UCS-E, follow these steps:
Step 1 Launch the Cisco vWAAS VM.
Step 2 Create a new directory to hold the extracted contents of tar.gz.
Step 3 Copy tar.gz into the specified directory.
Step 4 To extract the tar.gz gzip file, use the tar -zxvf Cisco-KVM-vWAAS-200-6.2.0.b-80.tar.gz command.
The contents of the tar.gz file are:
Step 5 Run the ezdeploy.sh script:
a. During execution of the ezdeploy.sh, you are prompted for bootstrap configuration parameters:
– vWAAS KVM name: The name is dependent on whether or not you provide the Cisco vWAAS’ bootstrap configuration.
If you have not provided the Cisco vWAAS’ bootstrap configuration: the name is set as the name of the guest KVM to be created. not the Cisco vWAAS’ host name.
If you have provided the vWAAS’ bootstrap configuration: the Cisco vWAAS’ host name is set and used in both instances.
– Cisco vWAAS local IP address and mask
– Default GW IP address: An address on the ISR-4000 series RP that is reachable by the Cisco vWAAS and has external network connectivity
– IP address of the Cisco WAAS Central Manager with which the Cisco vWAAS will register
– One NTP server address, without authentication. If you want to have authentication or multiple NTP servers, use the Cisco WAAS Central Manager to configure these after the Cisco vWAAS is powered up.
– (Optional) DNS server address
The ezdeploy.sh script performs a validation before accepting each parameter.
b. After input collection is completed, the following information is saved:
– The bootstrap configuration is saved in the bootstrap-cfg.xml file in the directory created for this KVM.
– The execution log and error log of the script are saved in the ezdeploy-log.txt file in the directory created for this KVM.
– For the Cisco vWAAS in this KVM, the error log is saved in errorlog/ezdeploy-errorlog.txt.
Note By default, all configuration and error logs saved in the specified KVM directory are not deleted, even if they have recorded errors. Therefore, you should allow for debugging. If you do not want to generate log files, you must confirm this choice at the end of the script execution, after input entry.
c. After the EzDeploy script is run, the Cisco vWAAS is fully up and running. Registration with the specified Cisco WAAS Central Manager and the NTP server are automatically started after installation of their corresponding CLIs.
- Optional: To view Cisco vWAAS, use the VM GUI or the virsh list command.
- Optional: To connect to the console, use the VM GUI or the virsh console vm-name command.
- Optional: To power down Cisco vWAAS, use the virsh destroy vm-name command.
- Optional: To undefine Cisco vWAAS:
1. Use the virsh undefine vm-name command.
2. Remove the directory with the specified vm-name.

This section contains the following topics:
- Unified OVA Package for Cisco vWAAS on KVM in WAAS Version 6.4.1 and Later
- Installing Cisco vWAAS on KVM in Cisco WAAS Version 6.4.1 and Later
Unified OVA Package for Cisco vWAAS on KVM in WAAS Version 6.4.1 and Later
For Cisco vWAAS on RHEL KVM in Cisco WAAS Version 6.4.x and later, Cisco provides a single, unified OVA or NPE OVA package for each hypervisor type, which can be used with all Cisco vWAAS models for that hypervisor.
Each unified OVA package file is a preconfigured VM image that is ready to run on a particular hypervisor. The launch script for each unified OVA package provides the model and other required parameters to launch vWAAS with WAAS in the required configuration.
The following are examples of the unified OVA and NPE OVA package filenames for vWAAS on RHEL KVM:
The unified OVA package for vWAAS on RHEL KVM and KVM on CentOS contains the following files:
- Flash disk image
- Data system disk
- Akamai disk
- INSTRUCTIONS.TXT: Describes the procedure for deploying the virtual instance and using the launch.sh file.
- package.mf template file and bootstrap-cfg.xml: These two files work together on the Cisco NFVIS platform with the image_properties.xml file as Day-0 configuration template.
- ezdeploy.sh: The script used to deploy vWAAS on UCS-E.
- exdeploy_qstatus.exp: The dependent file for the ezdeploy.sh script image_properties.xml. A VM configuration template file used on the Cisco NFVIS platform.
- launch.sh: The launch script to deploy Cisco vWAAS on Linux KVM.
- vm_macvtap.xml: Configuration file for vWAAS deployment using host machine interfaces with the help of the macvtap driver.
- vm_tap.xml: Configuration file for vWAAS deployment using virtual bridge or Open Virtual Switch (OVS) present in the host machine.

Operating Guidelines for Cisco vWAAS on RHEL KVM/KVM on CentOS
This section contains the following topics:
- Interoperability Guidelines for Cisco vWAAS on KVM and KVM on CentOS
- Traffic Interception Methods for Cisco vWAAS on RHEL KVM
Interoperability Guidelines for Cisco vWAAS on KVM and KVM on CentOS
Consider the following interoperability guidelines for Cisco vWAAS on KVM:
Interoperability guidelines for Cisco WAAS versions and Cisco vWAAS on KVM:
- Cisco vWAAS on RHEL KVM is available for vWAAS in WAAS Version 6.2.1 and later.
- Cisco vWAAS on KVM on CentOS is available for vWAAS on WAAS Version 6.2.3x and later.
Interoperability guidelines for OVS and vWAAS on KVM:
- The Cisco Discovery Protocol (CDP) is not supported for Open Virtual Switch (OVS) on RHEL KVM on CentOS, therefore the show cdp command cannot be used for Cisco vWAAS on RHEL KVM on CentOS.
- For Cisco vWAAS in WAAS Version 6.2.3x and later, there is inline Cisco vWAAS support for the OVS switch, with additional settings in Cisco vWAAS.
To configure inline Cisco vWAAS support for the OVS switch:
1. Install CentOS 7.2 on UCS-C240.
2. Configure OVS switch on the KVM host.
3. Deploy the KVM vWAAS OVAs with the OVS switch on KVM host.
5. Add two additional interfaces.
6. Using the virt-manager, map the bridge ID in Cisco vWAAS:
[root@localhost kvm]#
virsh edit vwaas-name
The domain vWAAS XML configuration is changed.
7. Using the virt-manager, edit the virtual type:
virtualport type=’openvswitch’/
<mac address='52:54:00:ea:3f:7b'/>
<virtualport type='openvswitch'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
<mac address='52:54:00:7f:7c:99'/>
<virtualport type='openvswitch'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
Traffic Interception Methods for Cisco vWAAS on RHEL KVM
For traffic interception for Cisco vWAAS on RHEL KVM, you can use WCCP (WCCP GRE or WCCP L2) or Cisco AppNav.
Note When you use any of the traffic interception methods for Cisco vWAAS on RHEL KVM, you must disable Generic Receive Offload (GRO) on the Cisco UCS NIC. Use the ethtool -K nic_interface_name gro off command on the KVM host to disable GRO, for example: ethtool -K enp3sof2 gro off. If you do not disable GRO, traffic is not recognized, and packets are discarded.
If you upgrade the Cisco UCS NIC firmware to the latest version, you do not have to disable the GRO parameter.
For more information on configuring traffic interception methods, see the Cisco Wide Area Application Services Configuration Guide.
Upgrade and Downgrade Guidelines for Cisco vWAAS on RHEL KVM
Consider the following guidelines when upgrading or downgrading your WAAS system with vWAAS on KVM:
- Cisco vWAAS on KVM is used in Cisco WAAS Version 6.2.1 and later. You cannot downgrade Cisco vWAAS on KVM or vCM on KVM devices to a version earlier than Cisco WAAS Version 6.2.1.
- When upgrading Cisco vWAAS, do not upgrade more than five Cisco vWAAS nodes at the same time on a single Cisco UCS device. Upgrading more than five Cisco vWAAS nodes at the same time may cause the Cisco vWAAS devices to go offline and diskless mode.
- For a Cisco vCM-100 model used with the RHEL KVM or KVM on CentOS hypervisor, with the default memory size of 2 GB:
When you upgrade to WAAS Version 5.2.1 from an earlier version, or downgrade from WAAS Version 5.2.1 to an earlier version, and use either the restore factory-default command or the restore factory-default preserve basic-config command, the vCM-100 may not come up due to GUID Partition Table (GPT) boot order errors.
To resolve this situation, follow these steps:
1. Power down the Cisco vWAAS using the virsh destroy vmname command or the virt manager.
2. Power up the vWAAS using the virsh start vmname command or the virt manager.
Note This upgrade-downgrade scenario does not occur for Cisco vCM-100 models whose memory size is upgraded to 4 GB.
