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

[Matthew Bohnsack]

Progress: I managed to get a host setup and then a vm setup on the host,
but the VM won't start.  I'm looking for some help getting the VM to
start.  Details...

I was able to work around the VDSM host in a failed state issue (I think),
by doing a host reinstall from the engine web GUI, after specifying the the
root password for the host.  That is, I changed to password authentication,
instead of what was originally set to SSH PublicKey authentication.   After
the host reinstall completed, I was left with what appears to be an
all-in-one setup with the engine and a host running on the same server.
Maybe this would have worked automatically, without the re-install step, if
I had ovirt SSH keys setup for root as expected?

Question: Any hints on to how to debug this in terms of host install SSH
PublicKey auth not working?  What user is attempting to SSH from the engine
to the host with what private key to complete the setup?  I see an
ovirt-engine public key that was added to /root/.ssh/authorized_keys.  Is
this the public key that's expected to work with the automated all-in-one
host setup?  If so, where's the corresponding private key so I might
attempt to debug further?

After adding a virtual local disk to the new host and setting up a new VM
through the web interface, I tried to attempt to start the VM but got this
permission denied error in engine.log:

Question: How can I debug this VM startup permission denied error further?
Is there a command line I can issue that's similar to what ovirt engine is
attempting that can give me more detail?  Something I can strace?

The vdsm user can read the above referenced image just fine, so it's
something more than just simple filesystem permissions I think?:

Re: [ovirt-users] Network instability after upgrade 3.6.0 -> 3.6.1

[Jon Archer]

Stefano,

I am currently experiencing the same issue. 2x nic lacp config at switch, mode 
4 bond at server with no connectivity. Interestingly I am able to ping the 
switch itself.

I haven't had time to investigate thoroughly but my first thought is an update 
somewhere.

Did you ever resolve and get back to mode=4?

Re: [ovirt-users] R: Re: Network instability after upgrade 3.6.0 -> 3.6.1

[Jon Archer]

Hi Stefano,

It's definitely not the switch, it seems to be the latest kernel package 
(kernel-3.10.0-327.3.1.el7.x86_64) which stops bonding working 
correctly, reverting back to the previous kernel brings the network up 
in 802.3ad mode (4).


I know, from reading the release notes of 7.2, that there were some 
changes to the bonding bits in the kernel so i'm guessing maybe some 
defaults have changed.


I'll keep digging and post back as soon as i have something.

I partially solve the problem.

My host machine has 2 network interfaces with a bond. The bond was
configured with  mode=4 (802.3ad) and switch was configured in the same way.
If I remove one network cable the network become stable. With both
cables attached the network is instable.

I removed the link aggregation configuration from switch and change the
bond in mode=2 (balance-xor). Now the network are stable.
The strange thing is that previous configuration worked fine for one
year... since the last upgrade.

Now ha-agent don't reboot the hosted-engine anymore, but I receive two
emails from brocker evere 2/5 minutes.
First a mail with "ovirt-hosted-engine state transition

Additional detail...

I did engine setup with this where all paths are on local disk:

OVESETUP_CONFIG/isoDomainMountPoint=str:/home/ovirt-localdisk/iso

With this, I was able to upload an image like so:

Further, the engine web gui has no mention of the ISO storage domain

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

[Alan Murrell]

Everything seems to be good.  The install created the "ovirtmgmt"  
bridge without any issue.  At one point after I did the  
'engine-setup', I thought the host got stuck, as it seemed to stay on  
"[INFO] Connecting to the engine" for quite a bit of time, but my  
"screen" session just got broken.  I reconnected to the screen  
session, and was able to continue/finish the setup.


Logging in to the webadmin indicates all seems to be fine (network  
interfaces are good, no errors, survives a reboot)


Thanks for your insight on this! :-)

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

[Matthew Bohnsack]

I temporarily moved beyond both my issues with the VDSM host needing to be
reinstalled from the engine GUI and VMs not starting by doing a fresh
all-in-one install without any of our configuration management stuff.
I.e., it worked fine when I installed on top of a fresh CentOS 7.2 ISO
install.  I'll still need to get things working with our configuration
management system, but for now I'm making progress.  Any help with my
previous questions about how to debug the issues would still be very much
appreciated.

For even less attended and hopefully quicker deploys, you can try
ovirt-appliance. It's still not published on our repos, but you can use the
last one from jenkins:

[ovirt-users] Reply: host xxx did no satisfy internal filter Memory because its swap value was illegal.

[pc]

Hi Doron,
[repost...I forgot to change html to plain test again when I replied a few 
hours ago...sorry about the format..]

Thank you, I disabled swap on hosts, and migrated 2 vms from n33 to n34 an hour 
ago, everything's fine.
 
1) Just a little confused about how to caculate the value.
###and I quote,

And in your case we see the value is > 0.
This means that swap_total < (swap_free+mem_available) or in general
your host is swapping.

###data in my case:
[n34]
# free -m
 total   used   free sharedbuffers cached
Mem: 32057  31713344  0 78  13074
-/+ buffers/cache:  18560  13497
Swap:2   5098  24901

Physical Memory:32057 MB total, 18593 MB used, 
13464 MB free
Swap Size:  2 MB total, 5098 MB used, 24901 
MB free
Max free Memory for scheduling new VMs: 21644.5 MB

## formula in my case: 
swap_total - swap_free > mem_available
## substituting =>
swap_total = 2,  swap_free = 24901, mem_available = ?
(mem_available  is 344 or 13497 ? Obviously the former value match the fomula, 
right?)


2) suggestion
Disable swap on ovirt host should be explicit indicated in the document.(for 
instance: http://www.ovirt.org/OVirt_Administration_Guide)

Modifying fake_nics in vdsm.conf is still supported and should still
work (though it requires restarting both vdsmd and supervdsmd). If it
does not - please file a bug.

However, I would recommend to initially creat the dummy devices with
their proper name

ip link add dummy_1 type dummy

instead of creating them with dummy1 and then renaming them.

Re: [ovirt-users] oVirt 3.6.1 USB Host Device passthrough

[ovirt]

Hi All,

just to let you know that I have tested the 3.6.2 RC1 and I can confirm 
that both problems are fixed with this version.


1. USB device list get refreshed automatically
2. USB device could be attached to the VM through the frontend

So looking forward for the final release of 3.6.2!

Best regards and great work!
Christoph

Hi Michal,

thank you for the response.



2. The USB device list never get refreshed while removing or

Check out http://www.ovirt.org/Features/hostdev_passthrough
It's not really talking about usbbut you can pass the whole 
controller as well


Do you know if the bug fix in 3.6.2 will also solve this issue? I 
think the list should be refreshed while removing or inserting USB 
devices. It would be also OK if the list get refreshed if you click on 
"Refresh Capabilities" in the host section.


Best regards

Hi list,

I'm currently trying to get USB devices into a VM.
My host is running a oVirt 3.6.1.

I'm trying to use the GUI feature to add the device into the VM and 
I'm facing two issues:


1. I receive the following message while starting the VM:
Error while executing action:

:

  * Cannot run VM. There is no host that satisfies current
scheduling constraints. See below for details:
  * The host  did not satisfy internal filter HostDevice
because it does not support host device passthrough..

This will be fixed in 3.6.2. That check only applies to pci 
passthrough (for now you can enable your host for pci passthrough to 
unblock the run)

https://bugzilla.redhat.com/show_bug.cgi?id=1283708

2. The USB device list never get refreshed while removing or

Does anyone knows what I'm doing wrong or what I need to check?

I found for example the following description for oVirt 3.5.
http://wiki.rosalab.com/en/index.php/Blog:ROSA_Planet/How_to_use_USB_device_inside_VM_under_Rosa_Virtualisation_%28oVirt_3.5%29

But this is not helping me as I will have multiple USB devices with 
the same ID in the host.

It should have worked also in 3.5 in principle, not sure about your specific
problems.

In principle pre-creating the bridge should work, but is not commonly tested.

Perhaps you also had issues with NetworkManager?

I did.  I basically followed "Up and Running with oVirt 3.5", except I 
used 3.6 packages.



In both cases just had a simple network interface (no vlan/bonding/whatever)
and input it when asked?


Well, I pre-created the 'ovirtmgmt' bridge, as I had to do that under 
3.5 otherwise I ran into problems during setup.  I can't recall offhand 
what the bug was (I posted about it a while back), but perhaps whatever 
it was has been fixed in 3.6, and I shouldn't pre-create the 'ovirtmgmt'

After I sent my earlier e-mail on this issue, I played around with a 
couple things and actually got it up and working (the interfaces turned

the host.  it is at the office, so I won't have physical access to it 
until I go in in a few hours.



What exact versions (OS and ovirt)?


CentOS 7 minimal (after 'yum update', I think it it 7.2?).  oVirt is 
3.6.1, I believe (whatever version is installed form latest repo packages)


Since I have lost access, I suspect something happened to the 
'ovirtmgmt' interface.  There is nothing on it that matters, so I may 
just do a fresh install, but without pre-creating the 'ovirtmgmt' bridge 
and see if the setup does it (which I understand itis supposed to?)

installed  one vm centos6.7 64 bit in the KVM server  and tried to
configure Hosted engine ,getting the below error ,

*"Failed to execute stage ‘Environment Customization’: Hardware
virtualization support is not available :please check BIOS settings and
turn on NX support if available"*



Even though VT is enabled facing the issue  any setting needs to be done in

Would like to get this issue settled before I move on… Should I expect to see 
the hosted engine VM showing up in the “VMs” node, or is it a “hidden” VM 
because of it’s special status?

Also, I see that I can change the name of the 1st host if I select it in the 
“Hosts” node, and choose “Edit”… Would it cause any problem if I rename it 
there (how would that effect the engine VM, if at all?)

I already responded how it may be achieved, and specified that this will not be

After I do the minimal install I always stop and disable NetworkManager 
(and firewalld), anfd in the ifcfg-* files I set 'NM_CONTROLLED=no'. 
For good measure, I usually reboot also.



Please open bugs if it does not work.


Alright, I will do a fresh OS install on my server, not pre-create 
ovirtmgmt bridge, and run through the same steps as "Up and running with 
oVirt 3.5", except use 3.6 packages.  If it gets stuck and does not 
create the ovirtmgmt bridge, I will file a bug.


I file a bug with any other issues I encounter as well, if necessary.

I will report back on on results.

Regards,

Alan

Re: [ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

Also, just noticed that I’m getting the message “The Hosted Engine Storage 
Domain isn’t Active” in the Events pane, but I do not see that domain anywhere 
now in the Storage node in the Datacenter… What must I do to activate this?

Also, I see that I can change the name of the 1st host if I select it in the 
“Hosts” node, and choose “Edit”… Would it cause any problem if I rename it 
there (how would that effect the engine VM, if at all?)

Please share the /var/log/ovirt-engine/engine.log from the engine machine
If you are running 3.6.1 you should see the domain imported automatically.

Not sure what you are trying to do - deploy hosted-engine inside this vm?

Did you enable nested kvm?

Note that you need el (rhel or centos) 7 for the host, if using 3.6.
