Just installed a single host HCI with gluster, with only the engine vm running.

Is it expected this situation below?

# virsh -r list
 Id    Name                           State
----------------------------------------------------
 2     HostedEngine                   running

and

# virsh -r dumpxml 2

so hosted engine not using libgfapi?

Also, on hosted engine

[root@hciengine ~]# engine-config -g LibgfApiSupported
LibgfApiSupported: false version: 4.1
LibgfApiSupported: false version: 4.2
LibgfApiSupported: false version: 4.3
[root@hciengine ~]#

So that if I import a CentOS7 Atomic host image from glance repo as template and create a new vm from it,when running this VM I get

# virsh -r dumpxml 3

. . .

    <disk type='file' device='disk' snapshot='no'>
      <driver name='qemu' type='qcow2' cache='none' error_policy='stop' io='native' iothread='1'/>

I remember there was an "old" bug opened causing this default of not enabling libgfapi

Does this mean it was not solved yet?

If I remember correctly the bugzilla was this one related to HA:

https://bugzilla.redhat.com/show_bug.cgi?id=1484227

that is still in new status.... since almost 2 years

Is this the only one open?

Thanks Gianluca for the deep testing and analysis! Sahina, Simone, can you please check this?

 

Thanks,

Gianluca
