Subject [jira] [Commented] (CLOUDSTACK-10281) vSphere VM disks do not honor the Service Offering Provisioning Type selected
Date Wed, 14 Feb 2018 20:39:00 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-10281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16364745#comment-16364745

Isaac Truett commented on CLOUDSTACK-10281:
-------------------------------------------

I'm attaching the changes Alex and I made while trying to modify the clone behavior. 

Adding a VirtualDeviceConfigSpec to change the disk provisioning doesn't appear to do anything
here. Is there something else we need to do to change the device configuration during the
clone process?[^cloudstack-vmware-provisioning.zip]

> Regardless of the Provisioning Type selected (Fat, Sparse, Thin), all instantiated vSphere
VM disks are thin when the storage supports thin.
> Doing a little sleuthing, it turns out that the creation of data disks is easily fixed
in *VmwareStorageProcessor.java*
> However, the root disk is always created as a clone with the same disk type as the
template, which being ova is always thin.  The vSphere API seems to allow specifying the disk type
during clone, and we've taken a stab at that, but so far to no avail.
> Hoping someone can shed some light on this.  Code samples forthcoming.
> We are using Cloudstack 4.10, and vSphere 6.0
