Installation guide

-a — Specifies that an OS instance is being added to the PXE configuration.
-i "<description>" — Replace "<description>" with a description of the OS instance.
-p <NFS|HTTP|FTP> — Specify which of the NFS, FTP, or HTTP protocols to use for installation.
Only one may be specified.
-D <0|1> Specify "0" which indicates that it is not a diskless configuration since pxeos can be
used to configure a diskless environment as well.
-s installer.example.com — Provide the name of the NFS, FTP, or HTTP server after the -s option.
-L <location> Provide the location of the installation tree on that server after the -L option.
For example, if the installation tree is exported as /install/rhel5 on an NFS share, specify -
L /install/rhel5.
-k <kernel> — Provide the specific kernel for booting. Installation trees can contain multiple
kernels.
For example, if the installation tree contain a patched kernel named vmlinuz-du alongside the
standard kernel named vmlinuz, use -k vmlinuz-du to specify the patched kernel.
-K <kickstart> — Provide the location of the kickstart file, if available. Specify this location as a full
path, including the protocol; for example: -K nfs:192.168.0.1:/install/rhel5/ks.cfg
<os-identifer> — Specify the OS identifier, which is used as the directory name in the
/tftpboot/linux-install/ directory.
If FTP is selected as the installation protocol and anonymous login is not available, specify a
username and password for login, with the following options before <os-identifer> in the previous
command:
-A 0 -u <username> -p <password>
p xeo s writes the results to the /tftpboot/linux-install/pxelinux.cfg/pxeos.xml file.
For more information on command line options available for the pxeos command, refer to the pxeos
man page.
The pxeb o o t tool can also edit the /tftpboot/linux-install/pxelinux.cfg/pxeos.xml file
and uses similar options to p xeo s. Refer to the p xeb o o t man page for more detail.
