INDUSTRY LEADING VIRTUALIZATION
PERFORMANCE

Red Hat

VMware

● SPECvirt_sc2010: As of September 1, 2012, RHEV claims top 7
results and the only 8-socket server scores


HYPERVISOR
● 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


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


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


KVM guests are processes, so we can confine
them like processes


Compromised virtual machine guest
confined, despite its vulnerability


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


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
