I am unable to get snapshots working in my devstack setup with the VCDriver.

When I tried to snapshot a vm instance, in the glance image-list, i could firstly see a new image was create and the status was "saving", few seconds later the created image entry disappeared from the image list and when i check the vCenter, in the task history, i found the "Create virtual machine snapshot" operation is completed but there is an error of the "Copy virtual disk" operation: "The requested operation is not implemented by the server."

Anyone has the same problem and know how to solve it? Is this a bug of vmware api with the devstack?

Thanks


updated info on sep23

After git clone the newest devstack repository on sep23 2013 and reinstall devstack, when i did a snapshot it still failed.

This time, from the vCenter task history i could see both the "Create virtual machine snapshot" and the "Copy virtual disk" operation are completed successfully. There was a "Copy virtual disk" operation failure before and now this issue is fixed in the new code i think.

From the horizon, the new created snapshot image status was firstly "queued" and then "deleted". And the snapshot image is not in the list when i do a nova image-list, glance image-list or look at the horizon image&snapshot list.

From the screen "g-reg" log, I found it seems like the snapshot image was created and then deleted before glance upload the image.

The output log is shown as followed:
