Greetings, this mail is sent via CC to ubunutu-devel, because I am not 100% sure if the found formating issue might originate from some ubuntu issue. libvirst-guests.sh on Ubuntu Xenial would not work correctly for me. Only one of the guests would be correctly suspended while the others were killed violently. Package: libvirt-bin Version: 1.3.1-1ubuntu2 /usr/lib/libvirt/libvirt-guests.sh The script writes a list of the VMs it will manage into /usr/lib/libvirt/libvirt-guests but I noticed it was in the format: <url> <vm uuid> <vm uuid> <vm uuid> and only the first VM was handled. After reading through the script and doing some try & error patches, I figured that the correct format should be: <url> <vm uuid> <vm uuid> <vm uuid> i.e. with no new lines. The attached patch makes sure the returned list of VMs does not contain new lines. This fixed the issue. Additionally I would suggest adding an information message on line line 444. Changing: [ -f "$LISTFILE" ] && return 0 to: [ -f "$LISTFILE" ] && echo "No VMs started by libvirt-guests.sh, not doing anything." && return 0 Regards, Michael Gajda
