There is no way to hotplug a CDROM device - only disk devices can be
hotplugged.
For CDROM/Floppy devices it is looking for an existing device with the
given name, and then trying to change the removable media in that
device.
The error you're getting shows that there is no such CDROM device with
the
name 'vda' in the guest already.
i have tested following
evil-desktop sss # virsh -d 0 attach-disk fuck
/home/sss/cd/mhdd32ver4.6.iso vdb --type cdrom
attach-disk: domain(optdata): fuck
attach-disk: source(optdata): /home/sss/cd/mhdd32ver4.6.iso
attach-disk: target(optdata): vdb
attach-disk: type(optdata): cdrom
attach-disk: found option <domain>: fuck
attach-disk: <domain> trying as domain NAME
error: Failed to attach disk
error: internal error: No device with bus 'virtio' and target 'vdb'

thank you for reply..
oh..., i have already implemented workaround for my needs, but it's much
harder than just create iso images.
thank you anyway.
