XenServer : The VM Needs storage that cannot be seen from that host

This issue is tricky because you need to know XenServer very well and understand the error message bellow while trying to launch a VM. The VM Needs storage that cannot be seen from that host

I attached a CIFS with all ISOs files I needed to the XenServer and the machine where the ISOs where failled. With this message I had to understand the VM didn’t want to boot because one ISOs was mounted in the virtual DVD drive and this ISOs wasn’t available any more…

I just had to empty the VM’s virtual DVD drive and everything came back to normal.

I am looking for a command line to empty virtual CD / DVD, if anyone have it, feel free to comment !
