Hi,

allowing to mount CDs in confidential VMs does not seem too dangerous as 
this is triggered by the admin.

This is useful for installation and sometimes for cloud configuration
data. Also allow vioscsi(4) so that cd(4) can attach somewhere. Also, some 
VMs may use vioscsi(4) disks.

thoughts? ok?

Cheers,
Stefan
