Hello List,
I'm attempting to pass a DVD drive of a headless server into a virtual
machine. So far I've managed to mount *something* into the VM, but
it's being registered as a blank DVD within the VM. When I mount
/dev/dvd into the bare-metal machine it registers normally as the DVD.
How do I pass physical drives into a VM and back out using libvirt?
Command used:
#virsh attach-disk Montreal /dev/dvd hdc --mode readonly --driver phy
--type cdrom
Connecting to uri: qemu:///system
Disk attached successfully

I haven't done this for a while but I believe you have to issue a
'detach' command afterwards.
