generate a kvm environment on vm
- login on vm
- edit /srv/kvm/config/imagename.conf and add this or similar settings
- if you edit nothing NIC1 is automatically int and NIC2 and NIC3 are not used
- start /usr/local/sbin/kvmrun imagename
- If no screen is running and if no image is present or if the image is too small for an installation it creates an image, a tunnel interface and starts a kvm with network boot option to make a FAI installation. After the FAI installation the KVM goes down and restarts with the harddrive boot option.
- If no screen is running but an image with a proper size exists the kvm starts booting this image in a screen.
- If a screen is running, kvmrun attaches to this screen.
A newly created hard drive image will be filled with a FAI
installation. The first KVM start uses the network boot option. There a
mac-address appears which was determined by kvmrun
. Put the
mac-address into the DHCP server and give the node a name, e.g.
. Write a proper PXE configuration for the FAI installation.
Tell the FAI server that this node belongs to the class
what kvmrun does
- it creates two tunnel intrefaces, if not present: tap_int_imagename and tap_ext_imagename and computes mac addresses using a hash algorithm
- Creates, if necessary, an qcow2 image which grows by demand. The name is _/srv/kvm/images/imagename.img.
- Creates or attaches to a screen with a session name imagename.
