May I note that nothing prevents you from doing both, as a customer.
If you find a bug, and want engineering to know about it, by all means open one.
If you also want support people help you, open a support case, and mention that
you also opened a bug (and its number). If you don't, and support decides it's
indeed a bug, they will likely open one for you eventually.

Best,

Re: [ovirt-users] Contents of Users digest Vol 65, Issue 215

[Joseph Kelly]

One other thing I noticed with our cluster is that the "hosted-engine 
--vm-status" does not return any details even thou the hosted engine is running:

node1 > hosted-engine --vm-status
node1 > virsh -r list
IdName   State

4 HostedEngine   running

node2 >  hosted-engine --vm-status
node2 >

Any one seen this before with ovirt-4.1 ?

Thanks,
Joe.

In my case I did the "hosted-engine -> deploy" step on the node the original 
install time and I can see these rpms and processes running on node#2 but its 
still not being sensed as a
valid node for failover. I also rebooted the 2nd node with no success Has

By default when you add an host in webadmin gui, it doesn't configure the
host as hosted engine host, but simply as host, so it cannot take in charge
the engine VM.
I opened a bugzilla to warn if only one host configured so and also to
change default
See
 https://bugzilla.redhat.com/show_bug.cgi?id=1399613

In the mean time you can reinstall host and in the relevant tab "Hosted
Engine" select "Deploy" choice

Hi All,

the Engine Gui is working fine and fast until I open the Hosts Tab and selected 
on of my Hosts. It's taking about 10 Seconds after selecting a Host until I can 
see any information for the Host. After doing this everything feels sticky 
until I logout and login again. This happens with any Browser.

Can you provide any hints on where to start looking for the cause of this ?

Thank you,

Sven

I didn't create a bugzilla, I logged a ticket with Red Hat Support.  We're
a RHEL and RHEV shop.

 Hi

 I see this also and I've logged a bug with Red Hat support on it.  I
 have found though that sometimes, if you wait long enough (i.e. approx 22
 minutes) it will eventually boot.

 The other thing I've found is that if you change from SPICE to VNC, the
 problem goes away completely.

 Thanks

 Hello Friends of oVirt

 Suddenly I have a super creepy bug:

 I can't boot a CentOS-7-x86_64-Minimal-1611.iso

 I check the sha256sum and everything is OK

 The Virtual Machine Stuck in:

 "EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts:
 (null)"

 or

 "systemd-journal[88]: Received SIGTERM from PID 1 (systemd).
 type=1403 audit(1487936348.599:2): policy loaded auid=4294967295

Hi Maton,

No, live snapshot, required for live storage migration is disabled on the hosted
engine vm, since it uses a volume lease, which would be invalidated by taking
a snapshot.

I hope that we can remove this limit by using vm lease instead of the the volume
lease, see:
https://www.ovirt.org/develop/release-management/features/storage/vm-leases/

Sorry, I was rolling back to 3.5 snapshots to test my 3.6 procedure
(trying to make sure I didn't just screw up), made a mistake, and
started over.

Now however, I can't do anything, because jpackage.org has really
screwed up their DNS - registered to 3 nameservers, two of which only
exist as glue records (not in authoritative DNS), and all three point to
the same IP (which is not responding).

After you imported the VM, yes.
During import, you can use the 'clone' option as you did before - it should
be fine as long as you're willing to have different identifiers (in most
cases, these identifiers have no functional implications).

Ah, ok... I retried with another VM, monitoring this time the behavior and
I see at  15:45 the message

Starting to convert Vm T-RHEL5-64

Then up to 16:04 it remains in "Initializing"
Only at 16:04 it begins the copying phase, with a "qemu-img convert"
command at host side that starts copying from an image in /var/tmp to the
chosen storage domain with an elapsed of about 3 minutes and final
completion
Previously I missed the final minutes of the process, so that I noticed
only the "Initializing" Status step and the final "Down" Status of the
VM

Ah, ok.
This explains why I get this message while importing a VM without selecting
"clone":

VM T-RHEL7 has MAC address(es) 00:50:56:b0:0c:7d, which is/are out of its
MAC pool definitions.
?
In this case to assign an oVirt MAC between the setup ones, only way is to
remove and add a new one or what?

Actually there is a progress bar for the phase of disks copying (after the
'initialization' phase) in the 'status' column of the virtual machines tab.

That means that the VM will be imported as a cloned VM - have different mac
addresses, different identifiers for the disks, different identifier for
the VM.

Ah, ok. Never tried before from web admin gui.
I confused in release notes of 4.1.0 with the feature:
BZ 1294629 Improve loading external VMs speed

Yes, I mean that during the 20 minutes elapsed time, it results that no
tasks are in execution.
Is this correct because it is considered a sort of external task or is it a
bug?

feature to provide.

And what about the "clone" option? In what is it different from no
selection of it?

[ovirt-users] oVirt 4.1: clone option of importing from VMware

[Gianluca Cecchi]

Hello,
I'm doing some tests to import VMs from VMware and verify functionality.
Great newcomer in 4.1
In my initial test, ESXi host is 5.5 and vcsa 6.0U2

What does it mean the "clone" check box I can select in the last screen
before running the import?

Also, after pressing OK it seems nothing is then running, apart the symbol
that VM is locked and its status is "initializing"
See here:
https://drive.google.com/file/d/0BwoPbcrMv8mvYWhwMllPSFRnakU/view?usp=sharing

BTW: the alerts are not related to the import...

The tasks(N) header shows tasks(0) as if no task in execution

In events I have:
Feb 27, 2017 2:01:35 PM Starting to convert Vm T-RHEL6-64
Feb 27, 2017 2:01:18 PM Starting to import Vm T-RHEL6-64 to Data Center
Default, Cluster Default
Feb 27, 2017 2:01:18 PM Add-Disk operation of 'T-RHEL6-64' was initiated by
the system.

>From hypervisor point of view I see:

[root@ovmsrv06 vdsm]# pstree 18777
vdsm─┬─3*[ioprocess───5*[{ioprocess}]]
 ├─tee
 ├─virt-v2v─┬─qemu-kvm───5*[{qemu-kvm}]
 │  └─virt-v2v
 └─50*[{vdsm}]
[root@ovmsrv06 vdsm]#

And after about 20 minutes (the original VM has only one thin provisioned
disk 4Gb/8Gb) the lock goes away and the status of the VM becomes down and
in events pane I get only now the sequence:

Feb 27, 2017 2:20:42 PM Vm T-RHEL6-64 was imported successfully to Data
Center Default, Cluster Default
It seems to me not so clear experience for the user importing, especially I
imagine in case of more than one import and with big disks.

Re: [ovirt-users] Ovirt engine disk size

[rightkicktech.gmail.com]

I deployed again the engine and indeed the disk was provisioned to the defined 
size, but I had to resize the filesystem of the endine disk to gain all the 
space. Seems that the disk is dd from the ova image which is 10G, and even when 
defining a different size the file system is still the one from ova disk.

[ovirt-users] GUI is slow when in Hosts Tab

[Sven Achtelik]

Hi All,

the Engine Gui is working fine and fast until I open the Hosts Tab and selected 
on of my Hosts. It's taking about 10 Seconds after selecting a Host until I can 
see any information for the Host. After doing this everything feels sticky 
until I logout and login again. This happens with any Browser.

Can you provide any hints on where to start looking for the cause of this ?

Thank you,

Sven

By default when you add an host in webadmin gui, it doesn't configure the
host as hosted engine host, but simply as host, so it cannot take in charge
the engine VM.
I opened a bugzilla to warn if only one host configured so and also to
change default
See
 https://bugzilla.redhat.com/show_bug.cgi?id=1399613

In the mean time you can reinstall host and in the relevant tab "Hosted
Engine" select "Deploy" choice

[ovirt-users] Hosting an oVirt test cluster on single machine running Fedora 25 with nested virtualization enabled.

[john]

Hi everybody,

I'm having a nightmarish time trying to test oVirt and RHEV on my main
machine which i just upgraded to Fedora 25 (before realising oVirt is
still on F24). Nevertheless, it seems to me I shouldn't have a problem
if i just use F24/RHEV/oVirt nodes running under my F25 machine. 

The F25 physical host is a pretty powerful machine, 8 (HT) cores, SSD
storage, 16 GB ram (bit light on RAM but this should be just sufficient
to run the engine & host, and say one test host)

Main problem is that i just cannot seem to add a new host to this
cluster.

I am using the F25 physical host to export NFS4 storage (on SSD),
for the oVirt cluster.

So currently, I have, all on one physical machine:

1) ovirt-engine-host vm - this is the F24 host which i ran hosted-engine
--deploy in. So, if the physical host is layer 0 (L0), this is L1.

VM has been given 3 CPUs, 6GB of RAM

2) ovirt-engine vm- this is the vm inside ovirt-engine-host, and this vm
is the main ovirt admin engine/appliance. The image for this appliance
was obtained from: ovirt-engine-appliance-4.1-20170201.1.fc24.noarch.rpm
So this vm is at L2.

According to the ovirt Manager web admin page, this is running:
oVirt Engine Version:4.1.0.3-1.el7.centos

When i ran the hosted-engine --deploy, I specified 2 CPUs, 4GB of RAM,
however, when i look at this host in the management webpqage, it
reports 3 CPU, and 6GB of RAM, so the hosted engine deploy script seems
to have ignored my wishes and given this vm the full resources of its
host vm, which is a little annoying but shouldnt be causing a problem at
this stage.

Basically, this seems to be working. I can login to the oVirt Manager
webpage and see my whole datacenter, storage, cluster, etc.

I've been able to add a data domain, and an iso storage domain, and
when i did this, the new data storage domain became the Master, and the
hosted_storage domain (holding my ovirt-engine host) appeared out of
nowhere in the UI. So i now have 3 storage domains - the hosted_engine,
the master, and iso storage.


So anyway, this is where the problems start. No matter what I try, I
can't seem to add a host to this cluster, which seems to be working
fine otherwise.

On all my F24 hosts Ive installed python2-dnf which is required by
oVirt on F24, installed nfs-utils so it can mount nfs shares, enabled
ovirt repository, setup static IP address, tweaked /etc/hosts so all my
hosts can see each other without relying on the physical KVM host's DNS.

I have tried:

1) create a new F24 VM under my physical host, so, at L1. I called this
ovirt-host-01. I have enabled CPU host-passthrough in KVM so this VM
can also run nested VMs, which is of course, the main objective. I've
given this VM 3 CPUs, and 6GB of RAM. Go to Management webpage and try
to add this as a new host. 

It ALMOST succeeds, but at the end it fails to mount my hosted_storage
domain. It correctly mounts the main master data domain, and the iso
domain, but fails to mount the hosted_storage domain. I can mount this
domain manually, and I just can't work out why this fails, it's
incredibly frustrating.

2) create a new host using the latest oVirt node iso:
ovirt-node-ng-installer-ovirt-4.0-2017011712.iso

node has 25 GB disk,3 CPUs, 6GB of RAM. Cockpit admin webpage reports
it is an "oVirt Node 4.0.6.1"

The node seems to be running fine, but i can't seem to add it to my
main cluster. The VDSM service is failing because it's not a member of
any domain. The main "System" tab in CockPit lists all the details,
but for Domain, it says: "Join Domain". Nowhere in this CockPit admin
webpage does there appear to be any way to actually specify the domain
to join.

So, I go to my main engine Admin page, and try to add this node as a
new host. It attempts to do so, but fails, after trying to trying to
install the package collectd, which is in epel. So i enable epel, even
though I'm sure something must be drastically wrong here, because this
oVirt node should have everything it needs already installed on it.
Trying to reinstall again, it fails with the exact same error in the
deployment log, saying collectd cannot be found even though it is
available from epel & epel repo is enabled.


Summary:

This is incredibly frustrating. Why is it so hard to add a host to an
oVirt cluster. This should be child's play. What is going on?

I have seen another email to this list saying you have to run hosted
engine deploy on bare metal (L0), so the engine vm is at L1,  or the HA
features of vdsm are pointless, but I'm not clear why that is, I was
hoping i should be able to get some sort of power management setup
eventually, KVM & virsh should be able to provide full power management
of the hosts even if i had to kludge together a few scripts myself.

Plus that still shouldn't prevent me from setting up this test cluster
surely. I know i haven't configured power management properly on the
hosts i'm adding, but, so what, they should at least work for testing
purposes.

If we set aside the power 

Re: [ovirt-users] ovirt 4.1 - is power management essential for hosted engine clustering ?

[Joseph Kelly]

By the way I noticed that ntpd wasn't running on the stock appliance engine 
provided as part of 4.1.
So I've installed and started that now, now both nodes and the hosted engine 
are now running ntpd, But it doesn't seem to have fixed my lack of failover.

From the RHEV 3.6 guide:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/pdf/Self-Hosted_Engine_Guide/Red_Hat_Enterprise_Virtualization-3.6-Self-Hosted_Engine_Guide-en-US.pdf

Subject: ovirt 4.1 - is power management essential for hosted engine clustering 
?
Date: Mon, 27 Feb 2017 16:02:26 +0900

Hello,

I've have a hosted engine thats up and running on a host called hosted-engine1. 
I installed hosted-engine2 via the webadmin gui but am unable to fail-over the 
hosted-engine.
However hosted engine-hosted2 is being sensed as a node in the default cluster 
and I have enabled HA reservation, as per this mail:

https://www.mail-archive.com/users@ovirt.org/msg34847.html

But is power management essential for hosted engine clustering ?

And I get this error below when trying to failover

"Cannot migrate VM. There is no host that satisfies current scheduling 
constraints. See below for details:

The host hosted-engine2 did not satisfy internal filter HA because it is not a 
Hosted Engine host..
The host hosted-engine1 did not satisfy internal filter HA because it is not a 
Hosted Engine host."

Thanks,
Joe.
