There was a time in early 2000 when the word "virtualization" was synonymous with VMware, and rightly so. After all, VMware started the second coming of this revolutionary technology after IBM. But open source hypervisor solutions such as Xen and KVM have been slowly nibbling at this market share and have made names for themselves in the past decade. Today, it is not uncommon to see multi-hypervisor deployments in a typical data center.Over time, virtualization technology has matured, and the hypervisors that form the basis of this technology have become feature rich. For basic tasks such as managing virtual machine life cycles or live migration, most major hypervisors are on par with the rest. But as technology essentially becomes a commodity, it’s normal for end users to try out cheaper alternatives to migrate either their existing virtual infrastructure or when building a new one. This is especially true for use cases that are not mission critical (low end quality assurance/development environments) and where an SLA drop from 99.99% to 99% doesn't trigger heartburn. Red Hat Enterprise Virtualization (RHEV), based on KVM, is precisely that solution with enterprise level support.Nessus support for hypervisorsTenable has offered solutions to audit virtual infrastructure for quite some time. We first added support for VMware vSphere/vCenter more than a year ago and followed it up by adding support for Citrix XenServer. And through support for WMI/PowerShell calls in an .audit file, Nessus customers could always run audits against Microsoft Hyper-V. Of the four major hypervisors, KVM was the only hypervisor that eluded us so far.Nessus v6 supports auditing RHEV, the Red Hat Enterprise Virtualization product based on the KVM hypervisorWith the release of Nessus v6, Tenable has added support for auditing RHEV, which is an enterprise virtualization product produced by Red Hat, based on the KVM hypervisor. The product is based on the oVirt project, which is its free, bleeding edge twin.The TNS RHEV AuditThe TNS Red Hat Enterprise Virtualization (RHEV) Audit taps into the RHEV API via the RHEV-Manager (RHEV-M), and reports comprehensive information that you may want to know about your RHEV setup in a Nessus report. For example, details include the list of users, running VMs, and stopped VMs across one or more RHEV-Hosts managed by RHEV-M. Admittedly, calling this audit a best practice audit would be a stretch, but calling it a connector is appropriate. The reason is because the APIs don't expose the same level of detail that you would expect from similar competing vendors such as VMware and Microsoft, and there isn't a best practice guide for RHEV from Red Hat either. Also, ssh access is disabled to the RHEV-Host, which limits the ability to audit.If you are an RHEV/oVirt

On the host issuing the command is disabled from monitoring the state of the engine virtual machine. The host is exempt from hosting the engine virtual machine while in local maintenance mode; if hosting the engine virtual machine when placed into this mode, the engine will be migrated to another host, provided there is a suitable contender. The local maintenance mode is recommended when applying system changes or updates to the host. none - Disables maintenance mode, ensuring that the high-availability agents are operating. Procedure 6.1. Maintaining a RHEL-Based Self-Hosted Engine (Local Maintenance) Place a self-hosted engine host into the local maintenance mode: In the Administration Portal, place the host into maintenance, and the local maintenance mode is automatically triggered for that host. You can also set the maintenance mode from the command line: # hosted-engine --set-maintenance --mode=local After you have completed any maintenance tasks, disable the maintenance mode: # hosted-engine --set-maintenance --mode=noneProcedure 6.2. Maintaining a RHEL-Based Self-Hosted Engine (Global Maintenance) Place a self-hosted engine host into the global maintenance mode: In the Administration Portal, right-click the engine virtual machine, and select Enable Global HA Maintenance. You can also set the maintenance mode from the command line: # hosted-engine --set-maintenance --mode=global After you have completed any maintenance tasks, disable the maintenance mode: # hosted-engine --set-maintenance --mode=noneProcedure 6.3. Maintaining a RHEV-H-Based Self-Hosted Engine In the text user interface, select the Hosted Engine screen. Select , and select a maintenance mode, either Local or Global. After you have completed any maintenance tasks, disable the maintenance mode. Select , and select None. 6.2. Upgrading a RHEL or RHEV-H 7 Self-Hosted Engine Environment The following procedure is only for upgrading a Red Hat Enterprise Virtualization 3.5 self-hosted engine environment running on Red Hat Enterprise Linux (RHEL) 7 hosts or Red Hat Enterprise Virtualization Hypervisor (RHEV-H) 7 hosts. New RHEL 7 hosts cannot be used in Red Hat Enterprise Virtualization 3.5 self-hosted engine environments; use the appropriate RHEV-H 7 host instead. See To upgrade your Red Hat Enterprise Virtualization self-hosted engine environment from version 3.5 to 3.6, update the Manager virtual machine, the self-hosted engine hosts, and any standard hosts. All hosts in a self-hosted engine environment must be the same version; you cannot upgrade only some of the hosts. During the 3.5 to 3.6 upgrade, at least one self-hosted engine host must be upgraded first. Upgrading the host will trigger the self-hosted engine storage domain upgrade. A new 3.6 host will not trigger the required upgrade. The self-hosted engine storage domain auto-import will happen automatically after a 3.5 host is upgraded with 3.6 packages. The upgrade process involves the following key steps: Place the high-availability agents that manage the Manager virtual machine in the global maintenance mode. Update the Manager virtual machine. Place a self-hosted engine host into maintenance. The Manager virtual machine and other virtual machines will be migrated to another host in the cluster if necessary. Update the self-hosted engine host. Repeat for all hosts. It is recommended to update all hosts.

Red Hat Enterprise Virtualization 3.6Installing and Maintaining the Red Hat Enterprise Virtualization Self-Hosted EngineAbstract A comprehensive guide to the self-hosted engine. Chapter 1. Introduction A self-hosted engine is a virtualized environment in which the engine, or Manager, runs on a virtual machine on the hosts managed by that engine. The virtual machine is created as part of the host configuration, and the Manager is installed and configured in parallel to the host configuration process. The primary benefit of the self-hosted engine is that it requires less hardware to deploy an instance of Red Hat Enterprise Virtualization as the Manager runs as a virtual machine, not on physical hardware. Additionally, the Manager is configured to be highly available. If the host running the Manager virtual machine goes into maintenance mode, or fails unexpectedly, the virtual machine will be migrated automatically to another host in the environment. A minimum of two self-hosted engine hosts are required to support the high availability feature. Table 1.1. Supported OS versions to Deploy Self-Hosted Engine System Type Supported Versions Red Hat Enterprise Linux Host 7.2 Red Hat Enterprise Virtualization Hypervisor Host 7.2 HostedEngine-VM (Manager) 6.7 It is important to synchronize the system clocks of the hosts, Manager, and other servers in the environment to avoid potential timing or authentication issues. To do this, configure the Network Time Protocol (NTP) on each system to synchronize with the same NTP server. 1.1. Installation OptionsSelf-Hosted Engine Hosts You can use Red Hat Enterprise Virtualization Hypervisors or Red Hat Enterprise Linux hosts, or both. Red Hat Enterprise Virtualization Hypervisor is distributed as an ISO file and contains only the packages required for the machine to act as a virtualization host. See Chapter 2, Deploying Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor Red Hat Enterprise Linux systems subscribed to the appropriate entitlements can be used as virtualization hosts. See Chapter 3, Deploying Self-Hosted Engine on a Red Hat Enterprise Linux Host. Self-Hosted Engine Manager You can use the RHEV-M Virtual Appliance, or you can install and configure the Manager virtual machine manually. The RHEV-M Virtual Appliance automates the process of installing and configuring the Manager virtual machine, and does not require you to access the virtual machine during the setup. Manually installing and configuring the Manager virtual machine is also supported but requires you to access the virtual machine directly during the setup. Chapter 2. Deploying Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor2.1. Installing Red Hat Enterprise Virtualization Hypervisor You will need to install a Red Hat Enterprise Virtualization Hypervisor machine before configuring self-hosted engine on it. For more information on storage requirements, see Storage Requirements in the Installation Guide. To use the RHEV-M Virtual Appliance for the Manager virtual machine installation, the data partition (/data) must be at least 60 GB. 2.2. Configuring Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor Once you have installed a Red Hat Enterprise Virtualization Hypervisor using the Hypervisor ISO, set up self-hosted engine using the screen. Self-hosted engine is currently supported on

Procedure 6.7. Upgrading Additional Hosts Access the Administration Portal. Select the host and place it into maintenance mode by clicking Maintenance. If the host is hosting the Manager virtual machine, the virtual machine will be migrated to another host. Any other virtual machines will be migrated according to your virtual machine migration policy. The high-availability agents are automatically placed into local maintenance. Ensure the required repository is enabled: # subscription-manager repos --enable=rhel-7-server-rhev-mgmt-agent-rpms Update the self-hosted engine host: # yum update Restart VDSM: # service vdsmd restart Restart ovirt-ha-broker and ovirt-ha-agent: # service ovirt-ha-broker restart# service ovirt-ha-agent restart Access the Administration Portal. Select the host and activate it by clicking Activate. Repeat the steps for all self-hosted engine hosts you want to upgrade. You can now update the cluster compatibility version to 3.6. Only update the compatibility version if all hosts have been updated for Red Hat Enterprise Virtualization 3.6 to avoid some hosts becoming non-operational. Procedure 6.8. Updating the Cluster Compatibility Version Access the Administration Portal. Select the Default cluster and click Edit to open the Edit Cluster window. Use the Compatibility Version drop-down menu to select 3.6. Click OK to save the change and close the window. 6.3. Upgrading a RHEL or RHEV-H 6 Self-Hosted Engine Environment This section describes how to upgrade a Red Hat Enterprise Virtualization 3.5 self-hosted engine environment, running on Red Hat Enterprise Linux (RHEL) 6 or Red Hat Enterprise Virtualization Hypervisor (RHEV-H) 6 hosts, to Red Hat Enterprise Virtualization 3.6, running on Next Generation Red Hat Virtualization Host (RHVH) or RHEL 7 hosts. The upgrade procedure comprises the following key steps: Upgrade the Manager Upgrade the hosts Perform post-upgrade tasks This procedure describes how to upgrade the Manager from 3.5 to 3.6. This procedure assumes that the system on which the Manager is installed is subscribed to the entitlements for receiving Red Hat Enterprise Virtualization 3.5 packages at the start of the procedure. If the upgrade fails, the engine-setup command will attempt to roll back the Manager installation to its previous state. For this reason, the repositories required by Red Hat Enterprise Virtualization 3.5 must not be removed until after the upgrade is complete. If the upgrade fails, detailed instructions display that explain how to restore your installation. Procedure 6.9. Upgrading the Manager Enable global maintenance from one of the self-hosted engine hosts: # hosted-engine --set-maintenance --mode=global On the Manager virtual machine, subscribe to the required entitlements for receiving the Manager 3.6 packages: # subscription-manager repos --enable=rhel-6-server-rhevm-3.6-rpms Update the rhevm setup packages: # yum update rhevm\*setup\* Run the following command and follow the prompts to upgrade the Manager: # engine-setup --otopi-environment=OVESETUP_DB/forceUpgradeWithHeEl6Hosts=bool:True Remove or disable the Manager 3.5 repository to ensure the system does not use any Manager 3.5 packages: # subscription-manager repos --disable=rhel-6-server-rhevm-3.5-rpms After upgrading the Manager, you can upgrade the hosts. These procedures describe how to upgrade the hosts to Next Generation RHVH or RHEL 7, using the host-direct-upgrade tool. host-direct-upgrade Tool The host-direct-upgrade tool provides a simple and fast way to upgrade.
