Removing virtual disks from datastore
Hello, we noticed that removing images and old revisions of images does not remove virtual disks from datastore. Assuming that we are positively sure that these are not needed is it safe to implement simple cronjob for removing deleted images and revisions? Thanks in advance, emir
HPC cluster setup
Hello, Now that I have VCL working to provide single virtual machines, how do I setup a cluster of machines in VCL ? How do I setup the situation where a user can reserve a small cluster out of a group of resources (a head node and child compute nodes) ? Thanks, Al Quiros

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Al, Pick an image to be the parent. Then, edit that image's profile by going to Manage Images and clicking Edit for the image. Click the Advanced Options section to expand it. Click the Manage Subimages button. Add any images you want to be part of the cluster (note that these changes are immediate; you don't click a save button or anything). Now, when you make a reservation for the parent image, you will get the whole cluster. Subimages are not recursive - - i.e. if you add a subimage that has subimages assigned to it, you only get the one subimage, not the subimage's subimages as well.

Re: HPC cluster setup
How you define the configuration of the parent node machine and the subimages machines?
