Migrate hosted engine to standalone host
by Anton Louw
Hi All,
So I have been playing around a bit, and I would just like some recommendations.
I moved my HE from an oVirt node to my VMware environment, basically running as a standalone host now. Is there anything I should look out for?
I can see there is a problem when configuring the HE after the move, where it says that global maintenance is not enabled. How will this work if the hosted engine is not sitting on a oVirt node anymore?
Any feedback\suggestions will be greatly appreciated.
Thanks
Anton Louw

Unable to connect to cockpit
by Parth Dhanjal
Hey!
I have a remote machine on which I have installed RHVH4.4
I'm unable to access the cockpit-plugin.
journalctl -u cockpit returns this error
cockpit-tls: gnutls_handshake failed: A TLS fatal alert has been received.
Screenshot while trying to reach cockpit through the browser attached.
Is anyone else facing this issue as well?
And does anyone has a solution/workaround to this?

Can't add freshly installed node.. host has no default route
by Giorgio Biacchi
Hi list,
I've spent a couple of days trying to understand why this was happening...
For the installation I have a well tested installation server with a
custom kickstart file to setup ssh keys and custom hooks for infiniband
and I'm installing Ovirt Node 4.3.9 via pxe, this is particularly useful
when I have to install a bunch of blades at once.. In the past I had no
issues and all was working like a charm until now when some hardware
failed and I had to replace it.
As expected I have no issues in the node installation process.. the
troubles begins when I try to add the node, installation fails and in
the UI I have an exclamation mark with the message "Host has no default
route." but I can ping and do ssh to the host from the manager.. the
problem is somewhere else in the communication between the engine and
vdsmd preventing the engine to refresh the host capabilities.
So from the engine I tried:
[root@manager ~]# openssl s_client -connect 172.20.22.78:54321
CONNECTED(00000003)
---
Certificate chain
0 s:/CN=cn128.lagrange.di.unimi.it/O=VDSM Certificate
i:/CN=VDSM Certificate Authority
1 s:/CN=VDSM Certificate Authority
i:/CN=VDSM Certificate Authority
---
The host has still the self signed vdsm certificate.. and on the host in
vdsm.log I find:
2020-05-11 09:52:25,433+0000 ERROR (Reactor thread)
[ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: SSLError,
address: ::ffff:159.149.129.220 (sslutils:264)
So I tried to enroll the certificate from the UI and from the events tab
I sow the enrolling was successful but:
[root@manager ~]# openssl s_client -connect 172.20.22.78:54321
140084336994192:error:140790E5:SSL routines:ssl23_write:ssl handshake
failure:s23_lib.c:177:
CONNECTED(00000003)
---
no peer certificate available
---
there's still some issue with the certificates.. so on the host again:
[root@cn128 vdsm]# find /etc/pki/vdsm/ -type f -cmin -10| xargs ls -l
-rw-------. 1 root kvm 1424 May 11 09:56 /etc/pki/vdsm/certs/cacert.pem
-rw-------. 1 root kvm 5108 May 11 09:57 /etc/pki/vdsm/certs/vdsmcert.pem
-r--r-----. 1 root kvm 1704 May 11 09:56 /etc/pki/vdsm/keys/vdsmkey.pem
-rw-r--r--. 1 root root 1424 May 11 09:57
/etc/pki/vdsm/libvirt-spice/ca-cert.pem
-rw-r--r--. 1 root root 5108 May 11 09:57
/etc/pki/vdsm/libvirt-spice/server-cert.pem
-r--r-----. 1 root root 1704 May 11 09:56
/etc/pki/vdsm/libvirt-spice/server-key.pem
It seems that cacert.pem and vdsmcert.pem have wrong permissions.. let's
try to fix it..
[root@cn128 vdsm]# chown 36:36 /etc/pki/vdsm/certs/cacert.pem
/etc/pki/vdsm/certs/vdsmcert.pem
And now:
[root@manager ~]# openssl s_client -connect 172.20.22.78:54321| less
CONNECTED(00000003)
---
Certificate chain
0 s:/O=lagrange.di.unimi.it/CN=172.20.22.78
i:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941
1 s:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941
i:/C=US/O=lagrange.di.unimi.it/CN=cn305.lagrange.di.unimi.it.35941
---
Now I can finally refresh the host capabilities and setup the host
networks..
In attachment all the relevant logs, I don't know if I've found some
bug.. this is the first time i had so many troubles adding a new host..
so I decided to share my experience with the list..
Cheers

If you don't see anything in any of the httpd logs, it means the
request that your browser sent didn't arrive to httpd.
Perhaps indeed you have some networking issue?
Can you ping/ssh/etc from inside the engine some machine outside
(other than the host it's on)?
The other way around - from the engine vm to outside?
If not, you should first fix that.
That said, I'd not expect a 503 in that case, but a timeout on your browser.
So either you didn't check the right log file (or there is some other
problem, such as full disk, iptables, whatever) or some other machine
returns you 503.
You can also check with a sniffer (tcpdump) on the engine machine to
see if it gets traffic, e.g.
tcpdump -i any port 80 or port 443

I am not sure the HA services show something different for "Can't
connect to the engine at all" vs "Health page didn't say it's
healthy".

Apologies, for got to add the below in the previous mail.
I do see a few of these “Bad Gateway” errors in the engine.log as well, not sure what this means though:

Thanks for the reply Didi.
I have checked the logs, but it does not seem to show anything when I try and access the WebUI. I run tail -f engine.log and tail -f server.log, but it remains still. This is the same case with the httpd logs.
I checked the status of the engine from my node, and it displays the below:

Everything network related seems to run fine, I can connect to the engine via ssh etc. as well.

Not necessarily everything, but even if you ask to remove only
something specific, it does more than that. We recently decided this
is too risky and removed that question:

1. When attaching complete logs (thanks for that!), please state the
exact time you tried
to do something that failed (access the web ui, in this case). Your
attached logs have
several different ERRORs, which might be due to unrelated things, and
it's hard to tell
where to look first. Once found, going backwards to try to find the
root cause is usually
easier.
2. Please check/share also httpd logs, and also /etc/httpd/conf.d -
you can compare it
with a fresh engine you can setup on some test vm somewhere, it should
be mostly the
same.
3. Also please check/share engine-setup logs, at
/var/log/ovirt-engine/setup. You can search
there for httpd or apache.
4. I have a feeling, just a guess, that you are missing
/etc/httpd/conf.d/z-ovirt-engine-proxy.conf .
Not sure what might have caused that. setup after cleanup should have
created it.
