![]() ![]() From this message it seems to me that it doesn’t actually mean the scsi bus, but the device type CDROM that is not supported for detaching: I tried to change my nf to have scsi drives (sd) as a default for cdroms. Ok, now that you mention it, when I think about how many times I properly hotplugged a IDE CDROM in hardware back in the day…no that was not very often CMD="virsh -connect $LIBVIRT_URI change-media $DOMAIN $TARGET_DEVICE \.There is a prefeconfigure action in KVM that uses change-media but it is only used to change the context after a new NIC is attached: OpenNebula/one/blob/master/src/vmm_mad/remotes/kvm/prereconfigure#L27-L28 print-xml print XML document rather than change media config alter persistent configuration, effect observed on next boot live alter live configuration of running domain current can be either or both of -live and -config, depends on implementation hypervisor driver Fully-qualified path or target of disk device As says the problem here is that you are attaching a cdrom drive in IDE bus and is not supported.You should readĬurrently OpenNebula does not support changing media of CDRoms, that I think it’s what you are looking for: # virsh change-media -helpĬhange-media - Change media of CD or floppy driveĬhange-media I think you will understand better if you read “Attach Drive” instead of “Attach Disk”. I just want to set this straight: does libvirt really NOT support hotplug for cdroms? I know this issue has been discussed on this forum quite often already. So it is actually useless that opennebula supports having persistent and non persistent cdrom types.Īnd actually i dont really see a use case where you would need a cdrom of type persistent, you cant write into a cdroms filesystem anyway. ![]() Mon Feb 6 11:39:21 2017 : Message received: LOG I 69 Command execution fail: cat I am experimenting with attaching and detaching of CDROM images in running VMs. ![]()
