Preping the environment

Installing the required tools

  1. yum install qemu-kvm
  2. yum install qemu-img

Getting the credentials

Eucalyptus credentials

See: https://help.ubuntu.com/community/UEC/CDInstall#STEP%205:%20Obtain%20Credentials

Vanilla image creation

Seems like EKI and ERI are something that is provide from outside the image. So it boot of of a kernel that is provided by the cloud vendor.

  1. yum install qemu-img
  2. qemu-img create -f qcow2 fedora.img 5G
  3. qemu-kvm -m 256 -cdrom ../isos/fedora14.iso -drive file=fedora.img,if=scsi,index=0 -boot d -net nic -net user
    • Why use vnc?: -nographic -vnc :0

creating a RHEL server image on ubuntu

  1. sudo su -
    • if the kvm is run as an ordinary user then there seems to be some timer hw issue in the guest.
  2. qemu-img create -f qcow2 diskimage.img 5G
  3. kvm -m 512 -cdrom rhel-server-6.1-i386-dvd.iso -drive file=diskimage.img,if=scsi,index=0 -boot d -net nic -net user
  4. go through the RHEL installation
    1. select keyboard, language etc.
  5. ::: install curl


Trouble shooting

KVM Issues

qemu network issues

Unable to connect to host os from within the guest

ping hosts does not get a response.

qemu-kvm issues

Boot failed: could not read the boot disk

  • if=ide

kvm -m 768 -drive file=diskimage.img,if=scsi,index=0 -net nic -net user


Running a the rescue op from the DVD fdisk provides:

  • fdisk -l /dev/sda
    • Partition 1 has different physical/logical beginnigs (non-linux?):
      • phys=(0, 32, 33) logical=(99, 115, 10)
    • Partition 1 does not end on cylinder boundary.

Show the same errors for partition 2, which is the LVM.

qemu-kvm: -net use: Parameter 'type' expects a network client type

  • it should be -net user

qemu-kvm -m 768 -cdrom Fedora-15-i386-DVD.iso -drive file=diskimage.img,if=scsi,index=0 -boot d -net nic -net use

Guest issues

Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring.

remove HWADDR from /etc/sysconfig/network-scripts/ifcfg-eth0
