OracleVM 3 PW drivers for Oracle Linux 5u7

So, to boot OL5U7, you pass xen_emul_unplug=never on the kernel boot line, which allows the machine to boot with the emulated devices, i.e. they are not unplugged.

Then, edit /etc/modprobe.conf to replace the emulated devices with xen-netfront and xen-blkfront:
Fiel /etc/modprobe.conf should look like this:
alias eth0 xen-netfront
alias scsi_hostadapter xen-blkfront

Then, rebuild initrd:
mkinitrd -f -v --builtin=ehci-hcd --builtin=ohci-hcd --builtin=uhci-hcd /boot/initrd-`uname -r`.img `uname -r`

And reboot. You may get kudzu renaming ifcfg-eth0 to ifcfg-eth0.bak on reboot, because it detects "new" hardware. If so, just rename it back and it should be fine.

PV-HWM drivers OracleVM 3.0.2 - 3.0.3

#alias eth0 8139cp
#alias scsi_hostadapter ata_piix
alias net-pf-10 off
alias ipv6 off
options ipv6 disable=1
alias sym53c8xx off
alias scsi_hostadapter xen-vbd
alias eth0 xen_vnif

and initrd shut be regenerated

mv /boot/initrd-2.6.18-274.el5.img /boot/initrd-2.6.18-274.el5.img.old ;
mkinitrd -v /boot/initrd-2.6.18-274.el5.img 2.6.18-274.el5 --with=xen-vbd --with=xen-vnif --preload=xen-balloon --preload=xen-platform-pci

LVM filter update

After LVM filter update LVM cache has to be removed

# By default we accept every block device:
#filter = [ "a/.*/" ] default
filter = [ "a|/dev/mpath/notblacklisteddevice|", "r|.*|" ]

rm /etc/lvm/cache/.cache
