Hi all,
while attempting a from-scratch self-hosted-engine installation on CentOS 6.5 (also freshly reinstalled from scratch) on a physical node (oVirt 3.4.0_pre + GlusterFS 3.5.0beta4; NFS storage for engine VM), the process fails almost immediately with:

[root at cluster1 ~]# ovirt-hosted-engine-setup --config-append=/root/ovhe-setup-answers.conf
[ INFO  ] Stage: Initializing
          Continuing will configure this host for serving as hypervisor and create a VM where you have to install oVirt Engine afterwards.
          Are you sure you want to continue? (Yes, No)[Yes]:

I already got another such report yesterday - seems like a bug in the fix for https://bugzilla.redhat.com/show_bug.cgi?id=1034634 .I hope to push a fix later today.

I look forward to have the fix pushed/merged in actual packages.


[ INFO  ] Stage: Clean up
[ INFO  ] Stage: Pre-termination
[ INFO  ] Stage: Termination

The /root/ovhe-setup-answers.conf has been saved from a previous installation (before reinstalling) and only minimally edited (removed some lines with UUIDs etc.).

The /etc/pki/libvirt dir is completely missing on both nodes; last time I tried the whole setup I do not recall of having such problems, but maybe something was different then.

The generated /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20140313010526.log has been saved as:

I hope to be able to progress further to test the whole 2-nodes setup (second node freshly reinstalled too and already up with GlusterFS and waiting to be added to oVirt cluster) and datacenter configuration.

Many thanks in advance for any suggestions/help,
For now, you can simply:mkdir /etc/pki/libvirt
This should be enough.

The workaround works: the self-hosted-engine installation proceeds now.

Thanks for the report!-- 
Didi

Many thanks for your kind and prompt assistance,
Giuseppe

 		 	   		  

Thanks for the report. The workaround is probably not enough, depends on what youare trying to do. 'mkdir /etc/pki/libvirt/private' is needed too. Without it, the code thatcopies there a key will create a file 'private' instead of copying it into a directory 'private'.
Fix [1] was merged to all branches.

Hi Didi,
the workaround seemed actually to be enough to make the self-hosted-engine setup go through up to the end without any user-visible error, but it left me with a non-running Engine VM afterwards (basically it did not restart up automatically under HA protection).

I collected all logs and reported it in a separate message with subject "Self-hosted engine setup ok but no engine vm running‏ " but got no comments yet.

If I get no suggestions I will try to perform some "corrective actions" based on my understanding of the problems at hand, but I did not want to "corrupt" the exact state to help in debugging (starting again from scratch with full first node reinstallation is a somewhat lenghty process since I have no local repo mirrors).

Many thanks again,
Giuseppe
