Maximum Concurrent Usage

This field allows the concurrent usage of the image to be limited. It is very useful if you only have a fixed number of licenses for an application installed in the image, but no network license manager to limit concurrent use. Set this field to 0 for unlimited use. Enter a number greater than 0 to limit concurrent use of the image to that number.

Estimated Reload Time

This is the estimated amount of time (in minutes) it will take the image to be loaded. It is only relevant for the first few reservations of an image. After that, historical data is used to estimate the load time.

Available for checkout

This field controls whether this image can show up on the Reservations page when selecting to make a new reservation (if set to yes, the appropriate permissions still need to be set for it to show up). The intended use of this field is for cluster environments where an image will have several sub images. In some of those cases, it doesn't make sense for end users to be able to make a reservation for the sub images directly. In those cases, set this field to No. Otherwise, you should leave it as Yes.

Check for logged in user

If set to yes, VCL will perform checks to see if a user is connected to a reservation for this image. If a user has connected, but disconnects and stays disconnected for 15 minutes, then VCL will consider the reservation to be inactive. It will time out the reservation and reclaim the machine for someone else to use. Setting this option to no disables this check, causing the reservation to exist until its end time, even if no one is connected to it.

Users have administrative access

Normally, it is desirable for users to have administrative access inside their reservations. Set this to No if the user should not have administrative access.

Set computer hostnameIf set to Yes, VCL will attempt to resolve the public IP address of the computer (whether from DHCP or the database) to a hostname and set the hostname of the computer to that. If the IP does not resolve, it will set the hostname of the computer to the hostname in the database. The default value for this field is Yes for Linux images and No for Windows and OS X images.
Connect MethodsThese are the ways by which users can connect to the image. Connect Methods explains more information about them.

Subimages

This is used to create Cluster Environments. Any subimages listed here will be reserved in addition to this image when a reservation is made for this image.
