Hi,
I have a very strange problem with libvirt. I work on some machines
with
libvirt (Debian/ Arch Linux) and libvirt set the ownership of images
file automatically to the qemu user / group for example on Arch
Linux to
nobody:kvm.
So when I copy an image file with root and use I then with qemu,
libvirt
change the owner/ group to nobody:kvm.
But I also compiled libvirt for a machine (gcc 4.9.4 glibc 2.12)
and on
this machine libvirt did not change the ownership of the image files
which results in this error:
libvirtError: internal error: process exited while connecting to

Can you please share the debug logs?
http://wiki.libvirt.org/page/DebugLogs
Also, my initial suspect, before diving any deeper is that usually,
when
users compile libvirt on their own, they forget to set the correct
prefix, therefore libvirt is looking for its config files NOT under
/etc/libvirt but /usr/local/etc/ or whatever.
BTW: is the daemon running under root?

Hi,
The daemon runs under root.
I uploaded the debug logs to:
http://people.ipfire.org/~jschlag/1363864/1_libvirtd.log
The UID of the user nobody is 99, the GID of the group kvm is 1011.
I added my configure options to the bug report.
Following the log the ownership is changed but why is the file still
owned by root:root?
Regards Jonatan
