Installation guide

Red Hat Enterprise Linux 6.1 and above provides an emulated (Intel) HDA sound device,
i ntel -hd a. This device is supported on the following guest operating systems:
Red Hat Enterprise Linux 6, for i386 and x86_64 architectures
Red Hat Enterprise Linux 5, for i386 and x86_64 architectures
Red Hat Enterprise Linux 4, for i386 and x86_64 architectures
Windows 7, for i386 and x86_64 architectures
Windows 2008 R2, for the x86_64 architecture
The following two emulated sound devices are also available, but are not recommended
due to compatibility issues with certain guest operating systems:
ac9 7, an emulated Intel 82801AA AC97 Audio compatible sound card
es1370 , an emulated ENSONIQ AudioPCI ES1370 sound card

Red Hat Enterprise Linux 6 provides two emulated watchdog devices. A watchdog can be
used to automatically reboot a virtual machine when it becomes overloaded or
unresponsive.
The watchdog package must be installed on the guest.
The two devices available are:
i 6 30 0 esb, an emulated Intel 6300 ESB PCI watchdog device. It is supported in guest
operating system Red Hat Enterprise Linux versions 6.0 and above, and is the
recommended device to use.
i b70 0 , an emulated iBase 700 ISA watchdog device. The i b70 0 watchdog device is
only supported in guests using Red Hat Enterprise Linux 6.2 and above.
Both watchdog devices are supported in i386 and x86_64 architectures for guest operating
systems Red Hat Enterprise Linux 6.2 and above.

There are two emulated network devices available:
The e10 0 0 device emulates an Intel E1000 network adapter (Intel 82540EM, 82573L,
82544GC).
The rtl 8139 device emulates a Realtek 8139 network adapter.
Emu lat ed st o rag e drivers
Storage devices and storage pools can use these emulated devices to attach storage
devices to virtual machines. The guest uses an emulated storage driver to access the
storage pool.
Note that like all virtual devices, the storage drivers are not storage devices. The drivers are
used to attach a backing storage device, file or storage pool volume to a virtual machine.
The backing storage device can be any supported type of storage device, file, or storage
pool volume.
