To create "OS container" from qcow2 image we have to check on "Customise configuration before install." before we click Finish. Then under "Filesystem" when we have to set: Type to "File", Driver to "Nbd", Format to "qcow2" and click Apply. Unfortunately, if we follow these steps we will get error message. The error is coming from the fact that "dev.source" has value None. This is because we just changed the filesystem type from "Mount" to "File". In result this condition [1] will be True and virt-manager will try to show the value of "./source/@file" which is None because the value of source was stored in "./source/@dir". Commits (2): Keep the value of filesystem/source when attribute is changed Set default Filesystem type for LXC to "Mount" .../compare/virt-install-fs-default.xml | 2 +- tests/xmlparse-xml/change-filesystems-out.xml | 4 ++-- tests/xmlparse.py | 2 +- virtinst/devicefilesystem.py | 25 +++++++++++++++++++--- 4 files changed, 26 insertions(+), 7 deletions(-) -- 2.9.4 _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
