Dear Michal and Pavel, We cover about 100 clients who have their own and simple CentOS KVM installations. Their technical skills are far from writing python scripts. They expect simple solutions. Talking to our helpdesk, I found that 70% of libvirt and virtualization problems are: A) lack of autostart activation on critical guests; then occasional failures and reboots affect lack of automatic startup of key services, B) frequent overcommiting of allocated virtual processors and memory due to the lack of basic planning and addition operations of local admin stuff :-(, C) misconfiguration of qemu-agent, which affects many problems with safe restart, snapshot, backup, etc. (the "Time" column is a perfect diagnostic here) D) leaving unnecessary snapshots that lie unused after many months, E) live migration attempts that fail to put domain in a transient mode leave the guests disappearing in unexplained circumstances after kvm host restart :-) Virtually all the above problems of everyday life, our helpdesk is now able to diagnose by command: virsh list --details --managed-save By the way, they can easily update the documentation with one compact list. I do not understand your dislike for the proposed changes. All the members of our team and teams of our partners have been very enthusiastic about the new functionality. You govern, so you have to decide. ;-) Przemyslaw Sztoch
