[Kimchi-devel] [RFC] About the way Kimchi deals with services (libvirt, nfs, etc)

[Daniel H Barboza]

Hello all,

I am working in a nfs related bug where kimchi hungs up if the nfs 
service stops for some reason while creating a NFS pool. I have a very 
similar situation Power-only with another service.

My idea at first was to verify the service status every time we request 
a specific service. This could work for actions that requires specific 
services, such as NFS. However, for this approach make sense, we should 
verify the status of libvirt for all the operations that depend of it. 
We would flood the code with "if (libvirt.service is active) " 
conditionals do to pretty much anything.

Thus, I am creating this RFC to ask you: how can we handle Kimchi 
dependencies on external services in a neat, clean way? Mark suggested 
to use systemd, for example.

Thanks!
