legacy PortIO CF8/CFC mechanism. To configure this, boot the system with the kernel parameter -
pci nomm config during installation and add pci=nom m conf to GRUB after rebooting.
Further, the AMD 8132 chipset does not support Message Signaled Interrupts (MSI). If your system
uses this chipset, you should also disable MSI. To do this, use the kernel parameter -pci nomsi
during installation and add pci=nom si to GRUB after rebooting.
However, if your specific platform is already blacklisted by the kernel, your system does not require
the aforementioned pci kernel parameters. The following HP platforms are already blacklisted by the

The Virtual Machine Manager (virt-manager) included in this release does not allow users to
specify additional boot arguments to the paravirtualized guest installer. This is true even when such
arguments are required to install certain types of paravirtualized guests on specific types of
hardware.
This issue will be addressed in a future release of virt-manager. To specify arbitrary kernel
arguments in installing paravirtualized guests from the command line, use virt-install.
With the default dm-m ultipath configuration, Netapp devices may take several minutes to
complete failback after a previously failed path is restored. To resolve this problem, add the following
Netapp device configuration to the devices section of the m ultipath.conf file:
devices {
device {
vendor "NETAPP"
product "LUN"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_netapp /dev/%n"
features "1 queue_if_no_path"
hardware_handler "0"
path_grouping_policy group_by_prio
failback immediate
