Para-virtualized device drivers can be installed after successfully installing a guest operating system. You will need a functioning host and guest before you can install these drivers.
Note
GRUB
), or a disk that contains the kernel initrd
images. Any disk which contains the /boot
directory or partition cannot use the para-virtualized block device drivers.
For Red Hat Enterprise Linux 3 based guest operating systems you must use the processor specific kernel and para-virtualized driver RPMs as seen in the tables below. If you fail to install the matching para-virtualized driver package, loading of the xen-pci-platform
module will fail.
