I am trying to add this volume to ESX pool. I have ESX server and got connected to it. When I listed the pool the data store of ESX server was getting listed down. So I was adding this volume to that. I want to create a domain but for that Matthias replied that I have to add volume which will put my .vmdk fole there. <div class="gmail_quote">On 15 Aug 2013 20:27, "Eric Blake" <<a href="mailto:eblake@redhat.com">eblake@redhat.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On 08/15/2013 08:30 AM, varun bhatnagar wrote: > Hi, > > I was trying to add volume...I got one xml snippet and I modified it > according to my node configuration: > > < volume> > <name>testNode/cluster.vmdk </name> > <allocation>0 </allocation> > <capacity unit='G'>2<capacity> > </volume> > > Now when I executed "virsh vol-create datastore1 /local/new_volume.xml" one > error message came saying: > > "Error: Failed to create volume from /local/new_volume.xml" > Error: internal error: Creation of raw volumes is not supported" What type of pool are you trying to add this volume to? This may be a case of no one having implemented the volume creation for your particular pool backend yet. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library <a href="http://libvirt.org" target="_blank">http://libvirt.org</a> </blockquote></div>
