Test on upstream libvirt-5.6: 1. Start a vm with scsi disk: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/tmp/scsi.qcow2'/> <target dev='sdb' bus='scsi'/> <serial>second-scsi</serial> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> 2. Cold plug a scsi disk with the same addr: # cat /tmp/scsi-cdrom.xml <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='sdd' bus='scsi'/> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> # virsh attach-device copy /tmp/scsi-cdrom.xml --config error: Failed to attach device from /tmp/scsi-cdrom.xml error: Requested operation is not valid: Domain already contains a disk with that address Works as expected. Although it works for this bug, I find such cases still failed: - scsi disk cold update with already used addr - sata disk cold plug with already used addr - sata disk cold update with already used addr - ide disk cold plug with with already used addr - ide disk cold update with already used addr Michal, could you fix them all together? Verified as comment1 on libvirt-5.6.0-5.module+el8.1.0+4229+2e4e348c.x86_64 qemu-kvm-4.1.0-10.module+el8.1.0+4234+33aa4f57.x86_64 For the issues of comment2, how about solve them by calling virDomainDefValidate at the end of qemuDomainAttachDeviceConfig and qemuDomainUpdateDeviceConfig?

Sorry for late response. Yeah that looks like a good solution. Currently I'm swamped with some other work so if you want to cook the patches I will happily review them.
