[Xen-users] Installig PV guest (Ubuntu karmic) on top of ubuntu dom0 (Ubuntu Karmic)

[Kangkook Jee <aixer77@xxxxxxxxx>]

Hi, all

I'm a Xen newbie who managed to install dom0 kernel and HVM guest. 
By observing insufficient network performance and thruput, I'm trying to 
install  PV guest but I couldn't find any standardized documentations for it or 
ready-made VM image that I can download and just use. 

What I tried so far are, 

i) by using virt-install command 
    #virt-install -n UbuntuPV -r 1024 -p --vnc -f /root/VMs/domu1.img -c 
~/ubuntu.iso --debug 
    ....
    ERROR    Paravirtualized guests cannot install off cdrom media. 

ii) using xm create command with following template

  kernel = "/usr/lib/xen/boot/hvmloader" 
  builder = 'hvm' 
  memory = 2048 
  name = "UbuntuPV"
  vcpus = 1 
  extra="root=/dev/xvda1"
  vif = [ 'type=ioemu, bridge=eth0' ] 
  disk = [ 
'file:/root/VMs/domu1.img,xvda,w','file:/root/ubuntu.iso,hdc:cdrom,r'] 
  device_model = '/usr/lib/xen/bin/qemu-dm' 
  vnc=1 
  boot='d'


  # xm create test.py 
  Using config file "./test.py".
  Error: Domain 'LucidPV' does not exist.


iii) using different template

  name="KarmicPV"
  memory=2048
  bootloader="/usr/bin/pygrub"
  kernel="/boot/vmlinuz-2.6.32.13"
  ramdisk="/boot/initrd.img-2.6.32.13"
  vif=['bridge=eth0']
  extra="root=/dev/xvda1"
  disk=['file:/root/VMs/domu0.img,xvda,w']
  vfb=['type=vnc,vncunused=1']

  ...
  Error: Boot loader didn't return any data!

but, all of above didn't worked out well. 
Thanks for your help in advance
