Hi everyone, libvirtd fails with this error when I activate VirtualMachineManager from the journal: May 08 16:10:05 delfassy libvirtd[26476]: libvirt version: 5.6.0, package: 10.el8 (CBS <cbs(a)centos.org&gt;, 2020-02-27-01:09:46, ) May 08 16:10:05 delfassy libvirtd[26476]: hostname: delfassy May 08 16:10:05 delfassy libvirtd[26476]: operation failed: pool 'default' already exists with uuid dd48b6ad-9a00-46eb-a3a4-c122d8a294a5 May 08 16:10:19 delfassy sudo[26639]: delfassy : TTY=pts/5 ; PWD=/home/delfassy/ovirt-engine-master ; USER=root ; COMMAND=/bin/journalctl May 08 16:10:19 delfassy sudo[26639]: pam_systemd(sudo:session): Cannot create session: Already running in a session or user slice May 08 16:10:19 delfassy sudo[26639]: pam_unix(sudo:session): session opened for user root by (uid=0) Among steps that I have tried were destroying the default pool and recreating it, removing all libvirt packages and virtual-machine-manager, erasing /etc/libvirt, and reinstalling them, all result with this error Has anyone encountered this error/ has an idea how to fix it? Thanks, Dana
