Hi Bjarne,
We will assist you to tty to get SALI working on your systems. grub or
grub2 is not part of SALI (kernel/initrd). It is in your client image. So we do
chroot (postinstall script) to install the grub/grub2 bootloader.
We use the following pxeconfig file. So you could ssh to installation node:
{{{
default rsync
label shell
kernel sali/trunk/kernel
append vga=extended initrd=sali/trunk/initrd.img ramdisk_size=32768
root=/dev/ram MONITOR_SERVER=si_monitor MONITOR_CONSOLE=yes SSHD=y
tmpfs_size=5000M rw
label rsync
kernel sali/trunk/kernel
append vga=extended initrd=sali/trunk/initrd.img ramdisk_size=131072
root=/dev/ram MONITOR_SERVER=si_monitor MONITOR_CONSOLE=yes PROTOCOL=rsync
tmpfs_size=2400M STAGING=/tmp GRUB2=yes SCRIPTNAME=amd64_squeeze_lisa.master rw
}}}
PS) If you use grub then delete the GRUB2=yes from the line
I must update the masterscript.new. But is still a good starting point for
implementing SALI
If something goes wrong you can ssh to the node:
* default root password is: SaliRoot
I only set the network parameters with systemconfigurator in a postinst script
(systemconfigurator must be installed in the image). In a feature release we
will make shell functions for this or something else.
01all.network
one_interface()
{
systemconfigurator --confighw --confignet --stdin <<EOL
[NETWORK]
HOSTNAME = $DEFAULT_HOSTNAME
[INTERFACE0]
DEVICE = eth0
TYPE = dhcp
EOL
}
For grub/grub2 we use this postinst script.
{{{ 02all.bootloader

then
echo "Using GRUB2 install method! :: $DISK0"
echo "grub-install --no-floppy $DISK0"
grub-install --no-floppy $DISK0

grub-mkconfig -o /boot/grub/grub.cfg

else
echo "Using Legacy GRUB install method!"
grub --batch <<EOF

setup (hd0)
EOF
echo "setting up grub: done."
fi
exit 0
}}}

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
