Version-Release number of selected component (if applicable):
libvirt-9.9.0-1.el9.x86_64
virtio-win-1.9.35-0.el9.noarch
How reproducible:
100%
Steps to Reproduce:
1. Prepare a guest with cdrom disk
# virsh dumpxml win2k19 --xpath //disk <disk type="file" device="disk"> <driver name="qemu" type="qcow2"/> <source file="/var/lib/libvirt/images/esx6.7-win2019-x86_64-sda" index="2"/> <backingStore/> <target dev="sda" bus="sata"/> <alias name="sata0-0-0"/> <address type="drive" controller="0" bus="0" target="0" unit="0"/> </disk> <disk type="file" device="cdrom"> <driver name="qemu" type="raw"/> <source file="/var/lib/libvirt/images/virtio-win-1.9.35.iso" startupPolicy="requisite" index="1"/> <backingStore/> <target dev="sdb" bus="sata"/> <readonly/> <alias name="sata0-0-1"/> <address type="drive" controller="0" bus="0" target="0" unit="1"/> </disk>
2. Check qemu cmd line
# ps aux |grep blockdev
....
-blockdev {"driver":"file","filename":"/var/lib/libvirt/images/virtio-win-1.9.35.iso","node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"} -blockdev {"node-name":"libvirt-1-format","read-only":true,"driver":"raw","file":"libvirt-1-storage"} -device {"driver":"ide-cd","bus":"ide.1","drive":"libvirt-1-format","id":"sata0-0-1"}
....
3. Query disks of guest
# virsh -c qemu:///system qemu-agent-command win2k19 '{"execute": "guest-get-disks"}' --pretty
{
"return": [
{
"name": "\\\\.\\PhysicalDrive0",
"partition": false,
"address": {
"serial": "QM00001",
"bus-type": "sata",
"bus": 0,
"unit": 0,
"pci-controller": {
"bus": -1,
"slot": -1,
"domain": -1,
"function": -1
},
"dev": "\\\\.\\PhysicalDrive0",
"target": 0
}
}
]
}
(No cdrom disk)
Actual result:
cdrom disk can not be displayed
Expected result:
cdrom disk can be displayed
Additional info:
1. cdrom disk in Linux guest can be displayed.
# virsh -c qemu:///system qemu-agent-command avocado-vt-vm1 '{"execute": "guest-get-disks"}' --pretty
