Description of problem: Can not list any mdev device if libvirtd quit after timeout when the existing mdev devices having different parent address Version-Release number of selected component (if applicable): libvirt-daemon-7.5.0-1.module+el8.5.0+11664+59f87560.x86_64 qemu-kvm-6.0.0-21.module+el8.5.0+11555+e0ab0d09.x86_64 mdevctl-0.78-1.el8.noarch How reproducible: 100% Steps to Reproduce: 1.Prepare 2 mdev devices xml with different parent address: #cat mdev-1.xml <device> <name>mdev_111fa1ca_18f6_4793_aa58_dcbfbb2e52db</name> <parent>pci_0000_9b_00_0</parent> <capability type='mdev'> <type id='nvidia-262'/> <uuid>25069f48-ceee-4c6a-a6f8-156fd7cf3e11</uuid> <iommuGroup number='0'/> </capability> </device> # cat mdev-2.xml <device> <name>mdev_83a54ae7_09b1_4046_b0e2_b31de31505a0</name> <parent>pci_0000_5b_00_0</parent> <capability type='mdev'> <type id='nvidia-260'/> <uuid>83a54ae7-09b1-4046-b0e2-b31de31505a0</uuid> <iommuGroup number='0'/> </capability> </device> 2.Define the mdev devices: # virsh nodedev-define mdev-1.xml Node device 'mdev_25069f48_ceee_4c6a_a6f8_156fd7cf3e11' defined from 'mdev-1.xml' # virsh nodedev-define mdev-2.xml Node device 'mdev_83a54ae7_09b1_4046_b0e2_b31de31505a0' defined from 'mdev-2.xml' 3.List the mdev devices,can show both of the mdev devices: # virsh nodedev-list --cap mdev --all mdev_25069f48_ceee_4c6a_a6f8_156fd7cf3e11 mdev_83a54ae7_09b1_4046_b0e2_b31de31505a0 4.Sleep 120 to wait for libvirtd quit: #sleep 120 5.List the mdev devices again: # virsh nodedev-list --cap mdev --all no output Actual results: Can not list any mdev device if libvirtd quit after timeout when the existing mdev devices having different parent address Expected results: Should always list the mdev devices successfully Additional info:
