I have Ubuntu 16 LTS (Desktop) as my local host machine. I installed KVM to
create virtual machines.
I have 3 virtual machines; one of them is acting as a master node to control
the other slave nodes (xCAT installed in the master node to control the slaves).
When I try to rpower off a slave node from the master node, the following error
occurs:
vm2: Error: Cannot communicate via libvirt to 127.0.0.1
When I researched there were many probabilities that may cause the issue:
unauthorized ssh, firewall, ports, etc.
I tried a lot of things but I felt lost and I'm just a beginner to the
open-source world. Can someone help me please with exact details and specific
commands?
Also, is there any way that I can reset my libvirt settings to the default
settings? Because I think I messed up some stuff which made the libvirt service
won't start.
Please help me ASAP.
Thanks.
