Convert XEN images on SLES 11 to vmdk format used by XenServer 6.2
On the SLES 11 XEN host, go to: /var/lib/xen/images and find the disk images in raw format. Then use qemu-img to convert the raw images.
e.g.:
qemu-img convert -f raw -O vmdk disk0-clone.raw disk0-clone.vmdk
The conversion took ~30min for a 100G disk image on Liszt.
I used samba on Liszt, and then created a SR on XenServer to access the disk images. XenServer then retrieved the vmdk thru CIFS import.
