Hi Robert,

   If hosted_storage and HostedEngine vm are not imported into the 
cluster, you will not be able to find HostedEngine tab in the edit / Add 
new host dialog . For this you will have to create first a storage 
domain which will automatically import hosted_storage and HostedEngine vm.


 Once you have the other two entities  you can simply move the host 
to maintenance and click reinstall. While re installing you should see a 
tab called Hosted Engine and choose 'Deploy' in that tab.


 Hope this helps !!

Thanks

[ovirt-users] trouble when creating VM snapshots including memory

2017-06-09 Thread Matthias Leopold 

hi,

i'm having trouble creating VM snapshots that include memory in my oVirt 
4.1 test environment. when i do this the VM gets paused and shortly 
(20-30s) afterwards i'm seeing messages in engine.log about both iSCSI 
storage domains (master storage domain and data storage where VM 
resides) experiencing high latency. this quickly worsens from the 
engines view: VM is unresponsive, Host is unresponsive, engine wants to 
fence the host (impossible because it's the only host in the test 
cluster). in the end there is an EngineException


EngineException: 
org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: 
VDSGenericException: VDSNetworkException: Message timeout which can be 
caused by communication issues (Failed with error VDS_NETWORK_ERROR and 
code 5022)


the snapshot fails and is left in an inconsistent state. the situation 
has to be resolved manually with unlock_entity.sh and maybe lvm 
commands. this happened twice in exactly the same manner. VM snapshots 
without memory for this VM are not a problem.


VM guest OS is CentOS7 installed from one of the ovirt-image-repository 
images. it has the oVirt guest agent running.


what could be wrong?

this is a test environment where lots of parameters aren't optimal but i 
never had problems like this before, nothing concerning network latency. 
iSCSI is on a FreeNAS box. CPU, RAM, ethernet (10GBit for storage) on 
all hosts involved (engine hosted externally, oVirt Node, storage) 
should be OK by far.


it looks like some obvious configuration botch or performance bottleneck 
to me. can it be linked to the network roles (management and migration 
network are on a 1 GBit link)?


i'm still new to this, not a lot of KVM experience, too. maybe someone

That's not a answer to my question. I can always build one manually. I know how 
to build a VM/contenaire from that, but I will still need to fill it with fake 
data, and needs to update it for every release of ovirt.

With a prebuild system, provided by oVirt people, I could also run it on 
release candidate and help them find bugs.

For my ovirt cli, I would like to have unit tests. But there is nothing to test 
in standalone mode, I need a running ovirt with a database in a known state.

Is there some where a docker images with a toy setup, or a mock ovirt engine

Re: [ovirt-users] chrony or ntp ?

2017-06-09 Thread Fabrice Bacchella 

People might be suprised. I'm currently trying to understand what chrony did to 
my ntpd setup, it look like it killed it and puppet has hard time to 
reconfigure it.

And as it's not a 'ovirt update' but instead vdsm update seems to happen more 
frequently, some people might forget to read release notes and be disappointed.

If you are trying windows, you will need to install the appropriate drivers to 
make it work. Any linux (well except ubuntu) works out of the box, at least

vdsm ships a sos plugin for collecting logs useful for debug issues. Here
the dependency on sos is needed for ensuring the directory tree owned by
sos is in place for installing the plugin.
Also, ovirt-log-collector assumes sos is installed on the hosts.
Yes, sos is still useful, I often ask users to provide a sos report in
order to understand what's going wrong.

because it’s much more problematic to troubleshoot and fix then.
The main reason is by enforcing NTP service on the host we get a good time sync 
even for people who do not care/do not know anything about it and get the right 
setup from DHCP
As Sandro says there is no easy way to identify the capability in general, and 
chrony is the default in el7

You can just disable the chrony service(we rely on the fact it’s enabled by 
default) and install any other NTP service as you prefer

Other strange dependencies:
rpm -q --requires vdsm

returns:
sos
tree
NetworkManager-config-server

I don't use NetworkManager-config-server and never used it. There is just this 
lonely components.
I'm running Centos, not Redhat, what 'sos' is good for in this case ?
tree is for interactive shell, who can a python application needs it ?

There is a lot of other tools like openvswitch's and iscsi's that are not used 
in my setup. But I can understand that they are always installed. A modular 
approach would have been better but much more complicated to implement.

which, every one use it , even if it's not the best solution instead of the

Adding people involved in this change.
Please note the change has been reviewed and discussed on
https://gerrit.ovirt.org/#/c/73822/ for addressing
https://bugzilla.redhat.com/show_bug.cgi?id=1428419
and it moves from requiring ntp to requiring chrony.
So it was already deciding for you, you just both were in agreement :-)

Sadly:
# rpm -q --provides ntp
config(ntp) = 4.2.8p10-1.fc26
ntp = 4.2.8p10-1.fc26
ntp(x86-64) = 4.2.8p10-1.fc26

rpm -q --provides chrony
chrony = 3.1-4.fc26
chrony(x86-64) = 3.1-4.fc26
config(chrony) = 3.1-4.fc26

there's no way to require just the time synchronization capability like in
httpd providing the webserver capability:

# rpm -q --provides httpd
config(httpd) = 2.4.25-8.fc26
httpd = 2.4.25-8.fc26
httpd(x86-64) = 2.4.25-8.fc26
httpd-mmn = 20120211
httpd-mmn = 20120211x8664
httpd-suexec = 2.4.25-8.fc26
mod_dav = 2.4.25-8.fc26
webserver

# dnf provides webserver

In Fedora we may use boolean dependencies and install chrony only if ntp is
not already installed: http://rpm.org/user_doc/boolean_dependencies.html
but this feature is not available in RHEL / CentOS.

I let others explain why we are enforcing the dependency on the package
itself instead of moving vdsm to an error state if time synchronization is
disabled at runtime:

# timedatectl status
  Local time: ven 2017-06-09 11:45:18 CEST
  Universal time: ven 2017-06-09 09:45:18 UTC
RTC time: ven 2017-06-09 09:45:18
   Time zone: Europe/Rome (CEST, +0200)
 Network time on: yes
NTP synchronized: yes
 RTC in local TZ: no

# rpm -qf `which timedatectl`
systemd-233-3.fc26.x86_64

[ovirt-users] chrony or ntp ?

2017-06-09 Thread Fabrice Bacchella 
I haven't switched from ntp to chrony. So I have configured my puppet to remove 
it as it's now part of default installation of rhel.

I works well with everything except on vdsm, since last upgrade:

 # yum erase chrony
..
Removing for dependencies:
 vdsm  x86_64   
4.19.15-1.el7.centos   @ovirt-4.1   
2.6 M
 vdsm-hook-vmfex-dev   noarch   
4.19.15-1.el7.centos   @ovirt-4.1   
 21 k


Why vdsm depends on chrony ? Any time synchronisation solution is good. Is that 
the role of ovirt to chose for me ?
