Re: Unit libvirtd.service could not be found. on VM



Thanks, Daniel
I verified I had libvirt-daemon rpm on my laptop and reloaded its units, but that didn't solve the issue. I then checked the vms-
libvirt-daemon rpm was indeed missing on my vms. After I installed it & reloaded its unit files libvirtd.service was found, but as I started it, the error 'operation failed: pool 'default' already exists with uuid a42beb54-839e-437b-a48e-d06f6100205c' appeared again on my laptop.
I'm not sure if I was supposed to install libvirt-daemon rpm on the vms? if it was needed - how do I resolve the error now? and any idea why it was missing? I never had to install it before
if not - if you have any other thoughts/suggestions I'll be glad to hear :)

If the unit doesn't exist, then I suspect you are either missing the
libvirt-daemon RPM or systemd has not correctly reloaded its unit
files after install. (systemctl daemon-reload would fix the latter)
