RED HAT ENTERPRISE VIRTUALIZATIONHYPERVISOR
● Standalone hypervisor● Small footprint
● Customized 'spin' of RHEL + KVM● 'Just enough' RHEL to run virtual
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
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf11
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
RED HAT ENTERPRISE VIRTUALIZATIONSECURITY
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf12
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
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf13
KVM guests are processes, so we can confine them like processes
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf14
Compromised virtual machine guest confined, despite its vulnerability
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf15
And of course, the guest operating system can also run SELinux

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
RED HAT ENTERPRISE VIRTUALIZATION Update | Syed M Shaaf17
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
