[libvirt] RFE: virsh list improvement (--description and --details)

Hello, 1. Please add —description parameter to virsh list command. It should be similar to —title. It will be very helpful for administrators who like to leave the order and documentation after their work. 2. Please add new columns to virsh list (for —details): a) CPUs b) MaxMem c) Flags: p-persistent, t-transient, a-autostart, m-managed save, s-with snapshot(s) and total sum for column vCPUs and Mem. In my opinion it is very popular use case. It will help you control vCPU and memory overcommiting in very simple and fast way. Put flags on list will prevents many additional commands from being executed. You will get all important information in one place. 3. Please add —domtime parameter to virsh list command. It should show column with domain’s system time similar to virsh domtime domname --pretty. It will be very helpful for fast guest-agent checking for every domain. 4. Please add column Parent and Metadata to virsh snapshot-list. — Przemyslaw Sztoch
