This document discusses Red Hat Enterprise Virtualization (RHEV) 3.1. Key features of RHEV Manager include high availability, live migration, load balancing, templates, and centralized storage and network management. The RHEV hypervisor supports up to 160 virtual CPUs and 2TB of RAM per guest. RHEV 3.1 focuses on integration, a new Python SDK, removing the .NET admin portal, supporting new platforms like OpenJDK, and improvements to networking, storage, and the user interface.

machines
● Security hardened image
● Runs on all RHEL hardware
● with Intel VT/AMD-V CPUs
● Easy to install, configure and upgrade
● PXE boot, USB boot, CD or Hard
drive

SECURITY
RHEV inherits the security features of
Linux and RHEL
SELinux security policy infrastructure
Provides protection and isolation
for virtual machines and host
Compromised virtual machine
cannot access other VMs or host
sVirt Project
Sub-project of NSA's SELinux
community. Provides “hardened”
hypervisors
Multilevel security. Isolate guests
Contain any hypervisor breaches
11 RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf

12. Security - SELinux to the rescue
SELinux is all about labeling
● Processes get labels – virtual machines with
KVM are processes
● Files and devices get labels – virtual images are
stored on files and devices
● Rules control how process labels interact with
file labels and other process labels
● The kernel enforces these rules
12 RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf

13. KVM guests are processes, so we can confine
them like processes
13 RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf

14. Compromised virtual machine guest
confined, despite its vulnerability
14 RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf

15. And of course, the guest operating system
can also run SELinux

16. RHEV 3.0 ARCHITECTURE

RHEV-Manager is now a Java
application running on JBoss
EAP on RHEL

Backend database is now
PostgreSQL 8.4

New user portal, REST API,
Linux CLI

Support for multiple external
authentication sources

Red Hat IPA

Microsoft Active Directory

17. RHEV 3.0 - Integration
● Hook scripts are called at specific VM lifecycle events
● VDSM (management agent) Start
● Before VM start
● After VM start
● Before VM migration in/out
● After VM migration in/out
● Before and After VM Pause
● Before and After VM Continue
● Before and After VM Hibernate
● Before and After VM resume from hibernate
● On VM stop
● On VDSM Stop
➔Hooks can modify a virtual machines XML definition before VM start
➔Hooks can run system commands – e.g.. Apply firewall rule to VM
