The Unbreakable Enterprise Kernel adds support for PV drivers
in an HVM guest (PVHVM) on Oracle VM. The default is to
present only PV drivers when running in an HVM guest. To run
kernel-uek
fully hardware virtualized,
including the drivers, add the parameter
xen_emul_unplug=never
to the boot
parameters in /etc/grub.conf
, for example:
kernel /vmlinuz-2.6.32-300.2.1.el6uek ro root=/dev/VolGroup00/LogVol00 xen_emul_unplug=never
Adding this parameter makes the kernel also present the
emulated drivers as previously (for example, the
8139cp
network driver).
