Xen virtualization

  • need a xen specific kickstart file (both for dom0 and domU)
  • helper script to add a virtual machine, using an LV for the data:
    # Xen MACs start with: 00:16:3e
    # create a logical volume
    lvcreate -L 8G -n $NAME $VGNAME
    # install
    virt-install \
        --name=$NAME \
        --ram=256 \
        --os-type=linux \
        --os-variant=rhel5.4 \
        --location=/mnt/artemis/wspace/OS/CentOS/5.5/ \
        --disk path=/dev/$VGNAME/$NAME \
        --mac=$MAC \
        --nographics \
        -w bridge:xenbr0 \
        -x "cmdline ks=nfs: ksdevice=eth0"

    xm create NAME
