Good day to all. i have problems with cdrom hot adding code. currently i using virDomainAttachDevice with type=file, device=cdrom, dev=hdc, this code works for machine with one ide hdd and one ide cdrom, but this not work for machine with only one ide hdd, and i looking for solution to hot add cdrom to machine independent of existing devices or i need way to determinate which target device can be attached to vm. thanks in advance for any help.
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'
