My default, if you use an ISO with KVM/QEMU, libvirt will change the ownership of the ISO. That seems incorrect on a NAS, for a read-only ISO, read permissions is all that should be required of libvirt.
Background:
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1784001
Looking in /etc/libvirt/qemu.conf, this setting would fix this... why is the default not 0 here:
Whether libvirt should dynamically change file ownership
to match the configured user/group above. Defaults to 1.
Set to 0 to disable file ownership changes.
#dynamic_ownership = 1
Please consider making dynamic_ownership = 0 by default on TrueNAS. Its odd for some other subsystem to change the ownership, messing with any share's permissions/ownership/acl for read-only use is unexpected.
