Hi Ugo,


This will be a one-time procedure, and the KVM host and the VMs do not need a reboot but the
provisionCertificate API will restart the libvirtd process (just check if that can have any
side effects for your VMs/distro, on most modern distros restarting libvirtd does not have
any side-effects on existing running VMs).

Subject: Re: secure hosts communications

Hi Rohit,
I have a 4.11.2.0 ACS infrastructure (Ubuntu 16.04 with KVM hypervisor)
I see that all the hosts are in unsecure state from the UI and so the
live migration don't works (we had trubles with mgmt server).

I read in the documentation that launching the provisionCertificate API
(by pressing the appropriate button in the UI) the certificates will be
renewed/regenerated for already connected agents/hosts.

I do not understand if provisioning should be done manually on each host
or if the procedure should be done only once.

Do this procedure reboot the host or the instances that it contains?


Thanks

API. In the UI, go to your hosts that don't show up as secure and click on the key button
(a new button) to secure the host which calls the provisionCertificate API as well.

> Starting 4.11, agent and management servers will use an in-built CA framework to secured
hosts. Only in case of KVM hosts you may see an insecure state, otherwise all KVM hosts (agents)
and SSVM/CPVM agents will by default in Up state will be secured. There is an auth strictness
setting that should be true.
