Getting a virtual LWP under KVM

Jurjen Bokma

February

  1. Create a KVM disk


      kvm-img create -f qcow2 vdisk.img 80G
    Formatting 'vdisk.img', fmt=qcow2 size=85899345920 encryption=off cluster_size=0

  2. Create a virtual USB stick to boot from

    1. Go to the ROM-o-Matic site

      Surf to http://rom-o-matic.net/gpxe/gpxe-1.0.0/contrib/rom-o-matic/build.php (you may want to use a newer version, if any)

      Select USB Keychain disk image (.usb) as the output format.

    2. Embed the boot script

      Click the Customize button.

      Surf to http://lwp22.service.rug.nl/boot/lwpinstall.php?shortcut=production and copy the entire script you find there.

      Paste it into the Embedded Script box on the ROM-o-matic page.

    3. Fetch the boot image

      Click the Get Image button to fetch the boot image. Mine was called gpxe-1.0.0-gpxe.usb

  3. Start the VM


      kvm -net nic -net user -m 2000 -smp 2 -name pxe_boot_test -drive file=./vdisk.img,if=ide,index=0 -drive file=./gpxe-1.0.0-gpxe.usb,if=ide,index=1,boot=on

    That should give you a VM and start the LWP installer inside it.

  4. Use the installed VM

    The virtual machine so installed can be used with:

    kvm -net nic -net user -m 2000 -smp 2 -name pxe_boot_test -drive file=./vdisk.img,if=ide,index=0,boot=on
