Access is denied within a tmp dir created during the snapshot attempt: $ sudo ls -al /var/lib/nova/instances/snapshots/tmpkajuir8o total 204 drwx-----x 2 nova nova 4096 Sep 23 19:12 . drwxr-x--- 3 nova nova 4096 Sep 23 19:12 .. -rw-r--r-- 1 nova nova 197248 Sep 23 19:12 0ece1fb912104f2c849ea4bd6036712c.delta
If I chmod /var/lib/nova/instances/snapshots/tmpkajuir8o to 777 the snapshot is successful. In that case the user/group of the delta file changes from nova:nova to libvirt-qemu:kvm. So it appears that libvirt-qemu needs access to the tmp directory. The tmp directory is created at run-time and I'm not yet sure how the permissions are determined. The --x for other seems odd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864922 Title: ussuri libvirt missing access to /var/lib/nova/instances/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1864922/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
