[Users] RHEV-m hosts with certs configured

[navin p]

Hi,
   I have couple of RHEV hosts (ovpxen,RHV2, RHV10 etc)  and i'm trying to
connect from one of the client machine (C1). All the RHEV host have libvirt
modified by vdsm. It looks like the below

Now from the client C1 which cert should i place in /etc/pki/CA/cacert.pem
so that i can access from the client using the URI
qemu+tls://ovpxen.ind.hp.com/system.  Please note the host
IWFVM00772.hpswlabs.adapps.hp.com is ovirt managed host. It is not the
client.


My problem here is i can't change the hypervisor hosts as there are too
many of them and it is configured by vdsm . What certs should i take from
host so that i can use it in the client so that i can connect to multiple
hosts from the client using virsh or virt-manager . I need tls as remote
protocol as i'm trying to automate commands.

Regards,
Navin
