You should carefully evaluate applications and tools that heavily utilize I/O or those that require real-

time performance. Consider the para-virtualized drivers or PCI device assignment for increased I/O

performance. Refer to Chapter 10, KVM Para-virtualized (virtio) Drivers for more information on the para-

virtualized drivers for fully virtualized guests. Refer to Chapter 12, PCI device assignment for more

information on PCI device assignment.

Applications suffer a small performance loss from running in virtualized environments. The

performance benefits of virtualization through consolidating to newer and faster hardware should be

evaluated against the potential application performance issues associated with using virtualization.

For the list of all other restrictions and issues affecting virtualization read the Red Hat Enterprise Linux

6 Release Notes. The Red Hat Enterprise Linux 6 Release Notes cover the present new features, known

issues and restrictions as they are updated or discovered.
