if you start a VM with cdrom=none, throttle group object is generated: # qm config 123 boot: order=ide2;ide0 ide0: cdrom,media=cdrom ide2: none,media=cdrom kvm: 0 meta: creation-qemu=10.0.2,ctime=1750423164 scsi0: local:123/vm-123-disk-1.raw,size=1G smbios1: uuid=8ca437bc-4a11-4bf2-8a5d-61d5cf407670 vmgenid: 0ca5ca77-a0d8-4f32-a7c3-c3c752f0280e # qom-list /objects type (string) throttle-drive-ide2 (child<throttle-group>) throttle-drive-ide0 (child<throttle-group>) pc.ram (child<memory-backend-ram>) throttle-drive-scsi0 (child<throttle-group>) and switching that CD drom drive to using the host drive or an iso volume fails: Parameter verification failed. (400) ide0: hotplug problem - VM 123 qmp command 'object-add' failed - attempt to add duplicate property 'throttle-drive-ide0' to object (type 'container') switching ide0 to none while running removes the object, and then switching back to cdrom works, and the block nodes also look okay. for me, switching from cdrom to none to an iso file works correctly. starting the VM with iso volume attached and switching to either none or a different iso file also work correctly. @alexandre are you testing with all three patch series applied (qemu-server, pve-qemu-kvm, pve-storage)? _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
