[ovirt-users] Migration path: All-In-One to self-hosted engine?

[Alan Murrell]

Hi All,

I am just wondering if there is any sort of migration path for those  
running All-In-One setups to a self-hosted engine setup?

Alan

[ovirt-users] Self-hosted engine: Host cannot activate

[Alan Murrell]

I am attempting to install oVirt 3.6 on a CentOS7 host.  it is a  
single server, so I am trying to install a self-hosted engine.  I am  
able to install oVirt 3.5 self-hosted engine, but am having some  
problems doing it with 3.6.


Everything appears to go fine; the engine-setup completes  
successfully.  On the host, I pressed"1" to indicate engine-setup was  
complete, and it can connect to the webadmin but the host never  
becomes operational.


I am able to log in to the webadmin, and indeed the host is in a  
non-operational state.  When I click on the host then click on the  
"Virtual networks" tab, all my interfaces are showing a red arrow.


When I click on "Setup Host Networks", my "ovirtmgmt" network is  
unassigned.  Believing this to be why my host is not operational  
(since it is under "Required"), I assigned it to my management  
interface, but the interfaces still remain red.  In addition, the  
"ovirtmgmt" network does have a green arrow, but also the icon  
indicating "Out of sync".  If I click on "Sync All Networks", I get  
the following error:


"Error while executing action SyncAllHostNetworks: Network is  
currently being used"


which makes sense, since "ovirtmgmt" is assigned/in use.  I am unable  
to unassign ovirtmgmt.


Current status is this:

  - All network interfaces are showing the red "down" arrow
  - "ovirtmgmt" is assigned to my management NIC, but indicating that  
it is out of sync
  - I am unable to unassign the "ovirtmgmt" network (or at least, if  
I do, the "OK" button is greyed out)


I could destroy the engine VM and go through the setup again, with the  
idea of once it is installed and waiting for the host to become  
operational, I could do a "Sync All Networks" and see if the networks  
turn green and go from there.


I wanted to see what sort of insight I could get from here first.  I  
am not sure what logs would be useful to you, so let me know what you  
want to see and I and make them available (I will likely zip them up  
and post a link)


Something else I could try if this becomes a "puzzler" is to do a  
3.5.x self-hosted engine then perform an in-place upgrade to 3.6 and  
see if that works?  I would rather try to help make a direct 3.6  
install work, though...


Thanks, in advance! :-)

Regards,

Alan

You can probably add a reverse proxy or teak apache ajp proxy, however, this 
configuration will probably not be supported.

Supported branding modifications are outlined here[1].

If you are running 3.6.1 you should see the domain imported automatically.

[ovirt-users] Wrong nvidia drivers dependency for ovirt-hosted-engine-setup on CentOS 7.2

[Aleksey Chudov]

Hi,

I have installed package
ovirt-hosted-engine-setup-1.3.1.4-1.el7.centos.noarch on CentOS 7.2 and
nvidia drivers installed as dependencies. If I manually try to remove
nvidia drivers yum proposes to remove ovirt packages as well. I don't have
any nvidia devices in my servers so I consider this a dependency bug.
Please check the output below.

The uncompressed engine log for the period in question is 12M... Too large for 
a pastebin...

However, I grepped for ‘domain’ and that culls it down to 18 lines; the results 
are at: http://ur1.ca/od26u

Not sure where you got elrepo repos, but I do not think they are from
ovirt. Please try a clean setup without them. Do you need them?

 Hello,
 I have one testing host (only one host) with self hosted engine and 2 VM
 (one linux and one windows).

 After upgrade ovirt from 3.6.0 to 3.6.1 the network connection works
 discontinuously.
 Every 10 minutes HA agent restart hosted engine VM because result down.
 But the machine is UP,
 only the network stop to work for some minutes.
 I activate global maintenace mode to prevent engine reboot. If I ssh to
 the hosted engine sometimes
 the connection work and sometimes no.  Using VNC connection to engine I
 see that sometime VM reach external network
 and sometimes no.
 If I do a tcpdump on phisical ethernet interface I don't see any packet
 when network on vm don't work.

 Same thing happens fo others two VM.

 Before the upgrade I never had network problems.

Problem solved!!!

The file hosted-engine.conf had a wrong fqdn.
I don't think that this happened during upgrade... mybe thay my 
colleague did something of wrong...

My guess is that this is a consequence of your networking problems.

[ovirt-users] ovirt 3.6 centos7.2 all-in-one install: The VDSM host was found in a failed state.

[Matthew Bohnsack]

Hello,

I am attempting to build a fairly basic proof of concept ovirt 3.6 machine
with the engine, host and guests all on a single physical CentOS 7.2 box
with local storage (to start), but am running into issues where
engine-install produces the following error:

[ ERROR ] The VDSM host was found in a failed state. Please check engine
and bootstrap installation logs.


The engine webconsole seems to be working fine after this - I can login and
click around - but there's no host CPU/storage resources available, as
expected.  From the logs shown below, there seems to be an issue with the
vdsm installation process being unable to contact the engine host during
installation.  Any ideas what's going wrong and/or what I can do to debug
things further so I can move beyond this issue?

Thanks,

-Matthew


Steps I took to install and diagnose the problem:

1. Installed system with our configuration management system.

2. Deleted users using UID=36 (needed by vdsm user) and UID=108 (needed by
ovirt user).

3. Ensured that /etc/sudoers contained the line "#includedir
/etc/sudoers.d" so that /etc/sudoers.d/50_vdsm will take effect.

4. Made directories for isos and images:

# mkdir /state/partition1/images/; chmod 777 /state/partition1/images/
# mkdir /state/partition1/iso/; chmod 777 /state/partition1/iso/


5. Ensured selinux was disabled and no firewall rules were installed.

6. Installed RPMs:

# yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm

# yum -y install ovirt-engine ovirt-engine-setup-plugin-allinone
# rpm -qa | grep ovirt-release36
ovirt-release36-002-2.noarch


7. Installed engine with an all-in-one configuration (Configure VDSM on
this host? Yes):

[ovirt-users] Can I reduce the Java heap size of engine-backup???

[John Florian]

I'm trying to run the engine-backup script via a Bacula job using the
RunScript option so that the engine-backup dumps its output someplace
where Bacula will collect it once engine-backup finishes.  However the
job is failing and with enough digging I eventually learned the script
was writing the following in /tmp/hs_err_pid5789.log:

#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 2555904 bytes for
committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.
#
#  Out of Memory Error (os_linux.cpp:2627), pid=5789, tid=140709998221056

# Failed to write core dump. Core dumps have been disabled. To enable
core dumping, try "ulimit -c unlimited" before starting Java again
#


So is there any good way to reduce the Java heap size?  I mean I know
what -Xmx does, but where might I try setting it, ideally so that it
affects the engine-backup only?  Any idea of good setting for a very
small environment with a dozen VMs?

Re: [ovirt-users] oVirt 3.6: Dummy interfaces

[Alan Murrell]

Hi Frank,

Thanks for info!  Does your script automatically load the dummy module  
as well, or do you create a separate file in '/etc/modprobe.d' to load  
it (that's how I currently do my dummy NICs)


Thanks! :-)

Quoting "Frank Wall" :


Hi Alan,

Are dummy interfaces still supported in 3.6?


I'm running ovirt 3.6 AiO and dummy interfaces are working just fine.
Instead of modifying oVirt's python source files, I'd recommend you
rename the dummy interface(s) to match the required pattern.

I've setup a service for this by creating  
/etc/systemd/system/dummynics.service

with the following content:

[Unit]
Description=Rename dummy network interfaces for oVirt

[Service]
Type=oneshot
ExecStart=/usr/sbin/ip l set dev dummy0 name dummy_0
ExecStart=/usr/sbin/ip l set dev dummy1 name dummy_1
ExecStart=/usr/sbin/ip l set dev dummy2 name dummy_2
ExecStart=/usr/sbin/ip l set dev dummy3 name dummy_3
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target


Then enable this service as follows:

systemctl daemon-reload
systemctl enable dummynics
systemctl status dummynics

Of course, you need to use the new dummy_* names when configuring the
network interfaces. I'd recommend to reboot the host after making these
changes.


Regards
- Frank

Re: [ovirt-users] Self-hosted engine: Host cannot activate

[Kristof VAN DEN EYNDEN]

I have similar issues with all the hosts I add to oVirt. Ovirtmgmt is 
unassigned after setup while every server has a static address. 

What I can do is assign ovirtmgmt to an interface, set the static IP again, 
save it and then press the activate button on the host tab. After that all is 
fine

self-hosted engine, but am having some problems doing it with 3.6.

Everything appears to go fine; the engine-setup completes successfully.  On the 
host, I pressed"1" to indicate engine-setup was complete, and it can connect to 
the webadmin but the host never becomes operational.

I am able to log in to the webadmin, and indeed the host is in a 
non-operational state.  When I click on the host then click on the "Virtual 
networks" tab, all my interfaces are showing a red arrow.

When I click on "Setup Host Networks", my "ovirtmgmt" network is unassigned.  
Believing this to be why my host is not operational (since it is under 
"Required"), I assigned it to my management interface, but the interfaces still 
remain red.  In addition, the "ovirtmgmt" network does have a green arrow, but 
also the icon indicating "Out of sync".  If I click on "Sync All Networks", I 
get the following error:

"Error while executing action SyncAllHostNetworks: Network is currently being 
used"

which makes sense, since "ovirtmgmt" is assigned/in use.  I am unable to 
unassign ovirtmgmt.

Current status is this:

   - All network interfaces are showing the red "down" arrow
   - "ovirtmgmt" is assigned to my management NIC, but indicating that it is 
out of sync
   - I am unable to unassign the "ovirtmgmt" network (or at least, if I do, the 
"OK" button is greyed out)

I could destroy the engine VM and go through the setup again, with the idea of 
once it is installed and waiting for the host to become operational, I could do 
a "Sync All Networks" and see if the networks turn green and go from there.

I wanted to see what sort of insight I could get from here first.  I am not 
sure what logs would be useful to you, so let me know what you want to see and 
I and make them available (I will likely zip them up and post a link)

Something else I could try if this becomes a "puzzler" is to do a 3.5.x 
self-hosted engine then perform an in-place upgrade to 3.6 and see if that 
works?  I would rather try to help make a direct 3.6 install work, though...

Thanks, in advance! :-)

Regards,

Alan

engine-backup does not directly call nor need java.

AFAICS it only calls it indirectly as part of some other initialization
by running java-home [1], which is a script that decides what JAVA_HOME
to use for the engine. This script only runs 'java -version', which imo
should not need that much memory. Perhaps there is something else I do
not fully understand, such as bacula severely limiting available resources
for the process it runs, or something like that.

If you only want to debug it, and not as a recommended final solution,
you can create a script [2] which only outputs the needed java home.
Simply run [1] and make [2] echo the same thing. If [2] exists, [1] will
only run it and nothing else, as you can see inside it.

I do not think this will work - quite likely engine-backup will fail
shortly later, if indeed it gets access to so little memory. Please
report back. Thanks and good luck,

[1] /usr/share/ovirt-engine/bin/java-home
[2] /usr/share/ovirt-engine/bin/java-home.local

Re: [ovirt-users] Migration path: All-In-One to self-hosted engine?

I am not aware of anyone trying that.

You can start with [1]. Note that it does not deal with db creation - this is
discussed in [2], but also note that if you use 3.6, you can use the new
'--provision-*' options during restore.

Please carefully read both of them and understand what's to be expected.

Is this a semi-critical system? Or can you easily suffer a few days of downtime?

Do you intend/hope to use the existing storage domain? Note that hosted-engine
does not (currently?) support local storage - it requires some shared storage,
nfs/iscsi/fc. And also that people ran into locking issues with a loopback nfs
mount. So it seems like the best bet is currently loopback iscsi, which means
you'll have to copy your existing data over there somehow.

A rough plan can thus be something like, assuming you have plenty of disk space:
1. shutdown all VMs
2. create a loopback iscsi export domain and export your VMs there
3. Continue with [1] (and [2])
4. During hosted-engine deploy use a different iscsi data domain for the engine
5. After finishing, attach to that export domain and import your VMs from it

I might be missing some parts, didn't fully think this over.

It will be greatly simplified if you have a separate storage server.

from host:
/var/log/ovirt-hosted-engine-*/* (-setup and -ha)
/var/log/vdsm/*

from engine:
/var/log/ovirt-engine/*
/var/log/ovirt-engine/host-deploy/*

If last one is empty, it means the engine did not manage to get
host-deploy logs. Please check and try to copy what you find from /tmp
of the host while waiting for host-deploy ("Waiting for the host to
become operational").

Did you principally do exactly the same thing in 3.5 and 3.6?
In both cases just had a simple network interface (no vlan/bonding/whatever)
and input it when asked?

What exact versions (OS and ovirt)?

I also changed the subject.

Best,
