Managing Virtual CDs

A virtual CD (VCD) is a read-only ISO image file that resides on a storage device of the everRun system. You can use VCDs to make software installation media available to the VMs on your everRun system in ISO format.

Use the Virtual CD Creation wizard (in everRun Availability Console) to upload an existing ISO file, as described in Creating a Virtual CD.

After you create a VCD, you can boot from it to install a Windows or Linux guest operating system, or start a VM from a bootable recovery VCD. You can download a VCD to your local computer. You can also insert a VCD into a running VM to install software applications.

Caution: When you insert a VCD into a running, fault-tolerant (FT) VM, it prevents the everRun software from migrating the VM to a different physical machine in the event of a failure. To restore fault-tolerant operation, unmount and eject the VCD as soon as you finish using it.

You manage VCDs as described in:

Users who are assigned the role Administrator or Platform Manager can perform all VCD tasks. Users who are assigned the role VM Manager can perform all VCD tasks, except rename a VCD. (For information on assigning these roles, see Managing Local User Accounts.)
