i am new with ovirt and i installed ovirt engine 3.6 on centos
first login i create the host with fqdn of ovirt server but
powersavesettings. Firt i saw installing as status for host,
while nothing happend, I reboot the server. In engine.log i
initialization finished for Host", but i cant open the webgui.
do? Where can i look to find the error and what have i done
If host-deploy managed to finish, you can see its log in .
please try to (re)install the host.
ok i will have a closer look into the log. Actuall the WebGUI
services are up and running. How can i reinstall the host? Via
you mean the hostsystem with installed ovirt engine? thx
Not sure I follow.
The engine runs on some machine, let's call it "the engine
If it's a self-hosted-engine, it's running inside a VM managed by
Otherwise it's running elsewhere (on some physical machine, or
A "Host", in ovirt terminology, is where VMs run.
Now please describe what you did, what you now try to do that
work, and what you can find in logs that might be related.
If you can't access the web admin ui, that's a completely
problem than if you can't add a host to the engine.
as far i understand there are to ways to setup ovirt. One as
enginge for ha and with ovirt host in vm on storage
That's called "self-hosted-engine"
and hosted engine where
all runs on the same host.
This is called all-in-one .
So i setup hosted engine on same machine and in
installation process i setup iso_domain via nfs too. i have done
more yet. so as i can see and read from the manual i now have to
No. You are not supposed to setup the host from the web interface.
I didn't try that recently, but in the past there were issues
to what you wrote below. Please follow the instructions in that
Also please note that in 4.0, allinone will be dropped. Systems
wish to have everything on a single host will need to use
Also note that people reported locking issues with local nfs
it seems like the safest bet for now is to use nested kvm - run a
play the "Host" role, and another VM as an nfs server (or iscsi),
then either a third VM for the engine, or hosted-engine (meaning,
runs inside a VM running inside the first VM).
than network and than data domain and so on. now i setup the host
say new, put a name inside and the fqdn of the initial host of
like myserver.com. after that i saw the progress which says
wait several minutes and after that i got network time out and
the webgui. hope that helps
that sounds not good. As i understand the only way with ovirt from
will self-hosted-engine and i have to setup all in nested-vms if i
only can use one machine, right?
Not sure I completely followed.
allinone will not be supported in 4.
hosted-engine will be the only way to install an entire ovirt system
a single machine, _supported_ by ovirt. And as I said, even this one
require an external storage machine.
Of course you can use virsh/kvm or whatever other means for creating
and use them to setup ovirt.
Ok i will have to reinstall my testsystem. Is that the way todo:
Yes, but you can use the howto , which is perhaps more
So i have to install ovirt
on centos7, than create a kvm with centos for the engine than for
and last a kvm for the nfs and data domain with centos, or better to
iscsi du to performance? after that i can install the first virtuall
Depends on what you want to do.
BTW, I didn't mention glusterfs, mainly because I do not know it
but that's also something to consider.
sounds strange and complicated...
ovirt is not designed to manage a single machine. For a single
simpler libvirt frontends are easier to use. If you install it just
learn/test, that's how it goes.
ok i have to lunge. i have to migrate from proxmox to another
thing ovirt is just fine while open source.. so i asked in the irc for
situation and if ovirt does fit. i have only one server which should
few kvm vm guests (debian, centos, ubuntu...) and also for
the irc they point me to the all-in-solution, i think at that time
didnt know that it will not further supporter from version 4 onto..
situation 2 server are to much but i will later add more server with
(Re-adding the list, adding Sandro)
The plan for hyper-convergence is to require at least 3 hosts, so that
have a replica-3 cluster storage.
Perhaps we should reconsider allowing local storage with hosted-engine.
This will prevent HA, but will fit into the place of current allinone
usage. The next stage will be that users will ask to migrate this local
storage to shared one (or even gluster :-) ).
For a 2-cluster HA setup we do not have, or plan to have AFAIK, any
official support, but you can have a look at DRBD .
it woulhd be nice to have a "small" solution with ovirt for a single
host with local storage. logically there whould be no ha, but you can
always use it for kvm virtualisation and i think thats the main thing in
ovirt. all other with ha and external storage is good to have, but for
smaller situations or starting conditions to much to effort. Anywhere
you do a great job.
