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

[Osvaldo ALVAREZ POZO]

hello, 

I managed to install hoste-engine. 
I think 



yum localinstall http://dl.fedoraproject.org/pub/epel/7/x86_64/h/haveged-1.9.1-1.el7.x86_64.rpm 

-systemctl enable haveged 

systemctl start haveged 




cat /proc/sys/kernel/random/entropy_avail 



1888 
it was helpfull 

I lost connection for a while to the ovirt-node 

But I think the hosted-engine vm is not in the iscsi LUN. 
How can I see where is the VM located? 

Thanks

Hello, 

but the problem is that i am not able to finish the hosted_engine deploy. So, I am not able to modify the Vm, because procces stoped :-( 

thanks for the help 




Yes, adding entropy to the host should still help.

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

Actually the haveged workaround is to apply on engine server, tipically when it is deployed as a VM, not the host. 
HIH,

The effectiveness of HAVEGE (HArdware Volatile Entropy Gathering and Expansion) on virtual machines is quite debated. 
Having more entropy on the host could also help, but yes, we also have to add a virtio-rng device to the engine VM:
