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?
Use virsh vol-create <pool> <volume.xml> where the volume xml looks
something like this (adjust to your liking):
<volume>
<name>perms.img</name>
<capacity unit='M'>100</capacity>
<target>
<path>/var/lib/libvirt/images/perms.img</path>
<format type='raw'/>
<permissions>
<mode>0755</mode>
<owner>77</owner>
<group>77</group>
</permissions>
</target>
</volume>
And then use virsh vol-upload to populate the volume with what you want.
That ought to be enough.
HTH,
Martin
