[ovirt-users] ovirt hosted-engine deploy never works

Thu Sep 1 09:39:02 UTC 2016

hello, 

but normally it is not possible to install paquets on ovirt node 
that's way I wonder how to install haveged? 

yum localinstall is this the command? 

Thanks

hello, 

thanks very much 

yum installlocal haveged 

right ? It is a ovirt-node 4 

You have also to enable and start it if you didn't

hello, 

wath could be a reasonable level? 1000? 

BQ_END

Yes, I think so. 

BQ_BEGIN

do you have a procedure for this? 

BQ_END

If haveged is enough for you, 
yum install haveged 
systemctl enable haveged 
systemctl start haveged 
and wait till /proc/sys/kernel/random/entropy_avail goes back to a reasonable value. 

BQ_BEGIN

thanks

Hello, 
Thanks for hte fast reply. 

cat /proc/sys/kernel/random/entropy_avail 
133 

BQ_END

Ok, the issue is definitively here: 
You can try installing the haveged deamon or any other method to keep entropy at a reasonable level. 

BQ_BEGIN

it is a physical server Poweredge R710 

thanks

hello, 

Thanks for all the answers.

It's taking a long time on this step executing engine-setup on the engine VM:

In this step engine-setup is requiring a lot of entropy for cryptographic actions so a similar delay could be due to the lack of entropy on your system. 

Can you please check the entropy on your host? 
cat /proc/sys/kernel/random/entropy_avail 
is it a nested env?

Hello, 

I am trying to deploy ovirt hosted-engine (over iscsi, i do not have NFS) from cockpit web interface. 
I have: 
-1 ovirt-node (ovirt-node-ng-installer-ovirt-4.0-2016062412) 
-le rpm for the appliance ovirt-engine-appliance-4.0-20160819.1.el7.centos.noarch 

I have four network nics let's say nic1, nic2, nic3 and nic4. I use nic3 and nic4 for ISCSi 
I have the ovirt-node ip on nic1. 

Any time I try to deploy ovirt hosted engine from ovirt-node cockpit interface the result is the same, I receive a "time out message", and the ovirt-node cockpit web interface does not work anymore. 

The documentation does not talk about network card requirement I do not know where to look. 

should I use nic2 instead of nic1 when deploying hosted-engine? 

Any advice?

I suspect that you hist [ https://bugzilla.redhat.com/show_bug.cgi?id=1358530 | https://bugzilla.redhat.com/show_bug.cgi?id=1358530 ] 

Can you please check if the hostname of your host is correctly resolvable?
