12.3.3. Inst allat ion and Configurat ion of Para-virt ualiz ed Drivers on Red Hat
Ent erprise Linux 4
This section contains detailed instructions for the para-virtualized drivers in a Red Hat Enterprise 4
guest operating system.
Note
These packages do not support booting from a para-virtualized disk. Booting the guest
operating system kernel still requires the use of the emulated IDE driver, while any other (non-
system) user-space applications and data can use the para-virtualized block device drivers.
Driver In st allat io n
The list below covers the steps to install a Red Hat Enterprise Linux 4 guest with para-virtualized
drivers.
1. Copy the kmod-xenpv, modules-init-tools and modversions RPMs for your hardware
architecture and kernel variant to your guest operating system.
2. Use the rpm utility to install the RPM packages. Make sure you have correctly identified which
package you need for your guest operating system variant and architecture. An updated
module-init-tools is required for this package, it is available with the Red Hat Enterprise Linux
4-6-z kernel or newer.
[root@rhel4]# rpm -ivh modversions
[root@rhel4]# rpm -Uvh module-init-tools
[root@rhel4]# rpm -ivh kmod-xenpv*
Note
There are different packages for UP, SMP, Hugemem and architectures so make sure
you have the right RPMs for your kernel.
3. Execute cat /etc/modprobe.conf to verify you have an alias for eth0 like the one below.
If you are planning to configure multiple interfaces add an additional line for each interface. If
it does not look like the entry below change it.
alias eth0 xen-vnif
4. Shutdown the virtual machine (use “ #shutdown -h now” inside the guest).
5. Edit the guest configuration file in /etc/xen/YourGuestsName in the following ways:
Remove the “ type=ioemu” entry from the “ vif=” entry.
