[libvirt-users] Managing VMs across multiple physical hosts
Hello List, We’re currently managing VMs across approximately 26 physical hosts. We tend to migrate VMs around a lot to do things like spread load and keep VMs running when physical hosts are in need of package updates. Suffice it to say sometimes finding out which physical host a VM is currently running on can be a pain. Anyone know of an open source tool that will give me a snapshot of what’s running where across a list of physical hosts? Doesn’t have to be anything fancy. A command-line utility will do. Best, Daniel
Hi Daniel, mist.io is an open source project and a Saas for managing clouds, servers and KVM hypervisors. The open source version can be found on https://github.com/mistio/mist.io Feel free to open issues on what is missing from an ideal KVM management solution.

Looks like an interesting project for a number of reasons. Do you guys have a mailing list though? Cos I’ve run into a couple of installation issues that I need assistance resolving. -Daniel

the libvirt command to see what is running is simply 'virsh list' so if you have a config tool system like puppet/chef/ansible (or even remote ssh commands) you can simply send that command to each node. We use ansible, so a simple on liner would be: ansible all -i virt_list.ini -m command -a 'virsh list' --sudo where the file virt_list.ini is the list of VM hosts. That would output a listing that looks like this host-b2 | SUCCESS | rc=0 >> Id Name State ---------------------------------------------------- 4 vm34 running 5 vm42 running host-b3 | SUCCESS | rc=0 >> Id Name State ---------------------------------------------------- 3 vm2 running 5 vm12 running 7 vm33 running etc. so you would quickly see whats running where. With a little grep/awk/perl goodness, it would be trivial to pipe that output into a DB table that could searched and constantly updated. The more hardcore ansible guys could make some sort of playbook that would do the above, but the above shows you the way. -bill On 4/24/2016 4:01 PM, Daniel Corbe wrote:
