There's something really broken with your copy of libvirt. It looks like even this command would fail: virsh -c qemu:///session list Can you try the command from comment 5? Can you check that you can run libvirt in session mode in your environment? [stack@undercloud-0 ~]$ virsh -c qemu:///session list error: failed to connect to the hypervisor error: Cannot recv data: Connection reset by peer It seems to be a problem with permissions in the home directory. Try starting libvirtd by hand as the non-root stack user: [stack@undercloud-0 ~]$ libvirtd 2019-10-09 15:21:18.505+0000: 346395: info : libvirt version: 4.5.0, package: 24.module+el8.1.0+3205+41ff0a42 (Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>, 2019-05-15-13:28:11, ) 2019-10-09 15:21:18.505+0000: 346395: info : hostname: undercloud-0.redhat.local 2019-10-09 15:21:18.505+0000: 346395: error : secretStateInitialize:480 : cannot create config directory '/home/stack/.config/libvirt/secrets': Permission denied 2019-10-09 15:21:18.505+0000: 346395: error : virStateInitialize:667 : Initialisation of secret state driver failed: cannot create config directory '/home/stack/.config/libvirt/secrets': Permission denied 2019-10-09 15:21:18.505+0000: 346395: error : daemonRunStateInit:806 : Driver state initialisation failed /home/stack/.config exists, but /home/stack/.config/libvirt does not exist. Also SELinux is enforcing, so I guess it could be an SELinux issue. Also: $ touch .config/hello touch: cannot touch '.config/hello': Permission denied There are no SELinux AVCs, and the same happens with SELinux set to Permissive, so I think we can conclude it's not SELinux. danpb mentioned that it might be something to do with container permissions. I am not really sure, how can we help here. Please reopen or move to relevant component. Thanks. |
