Set permissions and ownership of disk image created by vol-upload

Hello, I am using libvirt 8.0 on Ubuntu 22.04 and would like to utilize the vol-upload command to upload a disk image: https://www.libvirt.org/manpages/virsh.html#vol-upload I am using the "directory" storage pool type: https://libvirt.org/storage.html#directory-pool However, when uploading the disk image, it gets written with octal permissions 0600 and owner root:root. Ideally I'd like this file to be owned by libvirt-qemu:libvirt-qemu with permissions 0660 so that the group can read it. I've tried the following, none of which seem to alter the owner or permissions: - change the umask in the libvirtd systemd unit - edit the user, group, and dynamic_ownership settings in /etc/libvirt/qemu.conf - run "virsh pool-edit default" and change the <mode>, <owner>, or <group> tags How can I configure libvirtd to create these uploaded files with the desired permissions and ownership? Thanks, Andrew
