Virtualisation on Logan's Nest

Convert .xva to .qcow2 (or raw)

Thu, 23 Jan 2014 00:00:00 +0000

Figured out while running below work.

Got the hint from: http://jolokianetworks.com/70Knowledge/Virtualization/Converting_from_Citrix_XenServer_to_Xen_open_source/Xenmigrate.py And got modded .py from: http://pastebin.com/MK5Da8CB

1. run tar -xvf {image}.xva

2. python xenmigrate.py –convert=./Ref\:directory_here/ test.img

1. Download Hyper-V image and extract .vhd

2. Covert it via running: qemu-img convert -O qcow2 NSVPX-ESX-10.1-119.7_nc-disk1.vhd NSVPX-XEN-10.1-119.7_nc.qcow2

3. Create a VM, mount the image.

4. Login via nsroot/nsroot and run ‘config ns’ for initial network setup. Oddly, this menu doesn’t list routing option including default gateway. Add it manually via ‘config add route 0.0.0.0 255.255.255.255 your_gateway_ip’

Note: I wouldn’t do this for any production system as it looks pretty inefficient way to extend volume size.
