Please provide the package NVR for which bug is seen:
libvirt-10.8.0-1.el10.x86_64
selinux-policy-40.13.9-1.el10.noarch
How reproducible:
100%
Steps to reproduce:
1. Prepare a inactive guest
# virsh list --all Id Name State ------------------------ - test shut off
2. Prepare the evdev device xml
# cat input.xml
<input type='evdev' >
<source dev='/dev/input/event3' />
</input>
3. Coldplug the input device repeatly
# virsh attach-device test input.xml --config Device attached successfully # virsh attach-device test input.xml --config Device attached successfully # virsh attach-device test input.xml --config Device attached successfully # virsh attach-device test input.xml --config Device attached successfully
4. Start the guest
# virsh start test Domain 'test' started
5. Check the guest xml
# virsh dumpxml test --xpath //input .... <input type="evdev"> <source dev="/dev/input/event1"/> <alias name="input3"/> </input> <input type="evdev"> <source dev="/dev/input/event1"/> <alias name="input4"/> </input> <input type="evdev"> <source dev="/dev/input/event1"/> <alias name="input5"/> </input> <input type="evdev"> <source dev="/dev/input/event1"/> <alias name="input6"/> </input>
Expected result:
Can not start the guest with multiple identical evdev devices.
Adittional info:
For hotplug case:
# virsh attach-device test input.xml Device attached successfully
# virsh attach-device test input.xml error: Failed to attach device from input.xml error: Requested operation is not valid: Setting different SELinux label on /dev/input/event1 which is already in use
When try to hotplug the same source evdev device, libvirt will report error.
