Hello,
i am new with ovirt and i installed ovirt engine 3.6 on centos
7.
After
first login i create the host with fqdn of ovirt server but
without
powersavesettings. Firt i saw installing as status for host,
but
after
a
while nothing happend, I reboot the server. In engine.log i
see
"VMs
initialization finished for Host", but i cant open the webgui.
What
can
i
do? Where can i look to find the error and what have i done
wrong?
If host-deploy managed to finish, you can see its log in [1].
Otherwise
please try to (re)install the host.
[1] /var/log/ovirt-engine/host-deploy/
Best,
Hi Didi,
ok i will have a closer look into the log. Actuall the WebGUI
doesnt
load,
services are up and running. How can i reinstall the host? Via
cli?
Or
do
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
machine".
If it's a self-hosted-engine, it's running inside a VM managed by
itself.
Otherwise it's running elsewhere (on some physical machine, or
some
other
VM).
A "Host", in ovirt terminology, is where VMs run.
Now please describe what you did, what you now try to do that
doesn't
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
different
problem than if you can't add a host to the engine.
Best,
Hi Didi,
as far i understand there are to ways to setup ovirt. One as
self-hosted
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 [1].
[1] http://www.ovirt.org/Feature/AllInOne
So i setup hosted engine on same machine and in
installation process i setup iso_domain via nfs too. i have done
nothing
more yet. so as i can see and read from the manual i now have to
setup
the
host,
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
similar
to what you wrote below. Please follow the instructions in that
page.
Also please note that in 4.0, allinone will be dropped. Systems
that
wish to have everything on a single host will need to use
hosted-engine.
Also note that people reported locking issues with local nfs
mounts, so
it seems like the safest bet for now is to use nested kvm - run a
VM to
play the "Host" role, and another VM as an nfs server (or iscsi),
and
then either a third VM for the engine, or hosted-engine (meaning,
engine
runs inside a VM running inside the first VM).
than network and than data domain and so on. now i setup the host
and
say new, put a name inside and the fqdn of the initial host of
host
engine
like myserver.com. after that i saw the progress which says
"installing.." i
wait several minutes and after that i got network time out and
cant
enter
the webgui. hope that helps
Good luck,
Hi,
that sounds not good. As i understand the only way with ovirt from
Version 4
will self-hosted-engine and i have to setup all in nested-vms if i
want
or
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
on
a single machine, _supported_ by ovirt. And as I said, even this one
will
require an external storage machine.
Of course you can use virsh/kvm or whatever other means for creating
VMs
and use them to setup ovirt.
Ok i will have to reinstall my testsystem. Is that the way todo:
http://www.ovirt.org/Features/Self_Hosted_Engine?
Yes, but you can use the howto [1], which is perhaps more
comfortable.
[1] http://www.ovirt.org/Hosted_Engine_Howto
So i have to install ovirt
on centos7, than create a kvm with centos for the engine than for
the
host
and last a kvm for the nfs and data domain with centos, or better to
use
iscsi du to performance? after that i can install the first virtuall
machine,right?
Depends on what you want to do.
BTW, I didn't mention glusterfs, mainly because I do not know it
well,
but that's also something to consider.
sounds strange and complicated...
ovirt is not designed to manage a single machine. For a single
machine,
simpler libvirt frontends are easier to use. If you install it just
to
learn/test, that's how it goes.
Hi,
ok i have to lunge. i have to migrate from proxmox to another
vm-system and
thing ovirt is just fine while open source.. so i asked in the irc for
my
situation and if ovirt does fit. i have only one server which should
run a
few kvm vm guests (debian, centos, ubuntu...) and also for
webservices. in
the irc they point me to the all-in-solution, i think at that time
they
didnt know that it will not further supporter from version 4 onto..
for my
situation 2 server are to much but i will later add more server with
ha
usability.
(Re-adding the list, adding Sandro)
The plan for hyper-convergence is to require at least 3 hosts, so that
you
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 [1].

Hello,
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.
best regards
