...es for example)? For better comprehension I'll show the sequence I'm doing (I might do it wrong of course): virsh -c "qemu:///system" snapshot-create --disk-only <domain-ID> I get the snapshot location from its XML description and then: qemu-img convert -f qcow2 -O qcow2 base_image.qcow2 snapshot.qcow2 At that point I mount it through libguestfs and inspect its content. Thank you.

Hello all Has anyone managed to embed gruff graphs into a PDF document using pdf::writer? The easy way (as far as I can see) would be to just save the gruff graph as a temporary file then read that file in pdf::writer. I was wondering if anyone had managed to get them working together directly? RJ -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~

...created and started successfully. However, quite a few of my domUs don''t start properly. I get the correct Started Domain messages... but then the domain doesn''t "go anywhere", meaning it uses .3 cpu time, then never any more. I create the domUs by dd if=/dev/xen/base_image of=/dev/xen/ new_image, after creating a new_image using lvcreate of the same size as the base image. I''ve verified that these images actually exist. Looking through the log from xend.log below, i see an error about / dev/hda1 (the root device given to the domU on the command line,...

This is a "merge" of two previous series: https://www.redhat.com/archives/libguestfs/2018-December/msg00015.html https://www.redhat.com/archives/libguestfs/2018-December/msg00020.html The goal is to handle better situations like: - empty file in the appliance directory - no config files available in the packages to include in an appliance Compared to the two series, the changes are: -

Hello, It seems that a non-root user is able to copy root owned files. By that I mean a file that has "400" permission, for example. rsync <server_host_name>::base_image/etc/<root_owned_file> . The "rsyncd.conf" file has "uid=root" and "gid=root". What options do I need to use so that root can copy root owned files, but non-root users cannot copy root owned files? That is, how do I get rsync to honor file permissions the same...
