• When setting up interface bonding on
dom0
, the default
network-bridge
script may cause
bonded network interfaces to alternately switch between
unavailable
and
available
. This
occurrence is commonly known as
flapping
.
To prevent this, replace the standard
network-script
line in
/etc/xen/xend-config.sxp
with the following line:
(network-script network-bridge-bonding netdev=bond0)
Doing so will disable the
netloop
device, which prevents Address Resolution Protocol (ARP)
monitoring from failing during the address transfer process.

• The Hypervisor outputs messages regarding attempts by any guest to write to an MSR. Such
messages contain the statement
Domain attempted WRMSR
. These messages can be safely
ignored; furthermore, they are rate limited and should pose no performance risk.
(BZ#477647)
118
• Red Hat advises that you avoid removing a block device from a guest while the device is in use.
Doing so causes Xend to lose domain information for the guest.
(BZ#476164)

The following note applies to x86_64 Architectures:
• Installing Red Hat Enterprise Linux 3.9 on a fully virtualized guest may be extremely slow. In
addition, booting up the guest after installation may result in
hda: lost interrupt
errors.
To avoid this bootup error, configure the guest to use the SMP kernel.
(BZ#249521)

4.35. xorg-x11-drv-i810
xorg-x11-drv-i810 is an Intel integrated graphics video driver for the X.Org implementation of the X
Window System.
• Running a screensaver or resuming a suspended laptop with an external monitor attached
may result in a blank screen or a brief flash followed by a blank screen. If this occurs with the
screensaver, the prompt for your password is being obscured, the password can still be entered
blindly to get back to the desktop. To work around this issue, physically disconnect the external
monitor and then press the video hotkey (usually Fn-F7) to rescan the available outputs, before
suspending the laptop.
The following notes apply to x86_64 Architectures:
• If your system uses an
Intel 945GM
graphics card, do not use the
i810
driver. You should use the
default
intel
driver instead.
(BZ#468218)
121
• On dual-GPU laptops, if one of the graphics chips is Intel-based, the Intel graphics mode cannot
drive any external digital connections (including HDMI, DVI, and DisplayPort). This is a hardware
limitation of the Intel GPU. If you require external digital connections, configure the system to use
the discrete graphics chip (in the BIOS).

4.36. xorg-x11-drv-nv
xorg-x11-drv-nv provides a driver for NVIDIA cards for the X.org implementation of the X Window
System.
