<div dir="ltr"><div>I have an openstack created instance running within my vmware compute node.<br><br></div><div>The vmdk boot image I used to create this instance, is stored in glance and contains the below disk properties:<br><br></div><div>adapter type = lsiLogic<br></div><div>disk type = sparse<br><br></div><div>Now, if I use this image to boot an instance, all works as expected. No problems.<br></div><div>If
I create a volume with this image and try to boot from this volume, the
hypervisor complains that no operating system is found. If I attach the
volume to a running linux instance fdisk reports that no partition
table is found.<br><br></div><div>So I guess the question is, what step
am I missing when I create a volume from a sparse vmdk image ? When I
create a volume from a preallocated image, everything works fine. So
some step is missing when using sparse images to create a working cinder
volume.<br><br></div>Thanks!</div>
