Dear all,

I upgraded to 3.5.4.2-1.el7.centos, but I have still the Problem that I

Below some parts of the vdsm logs, does anyone have an idea to fix it,
please help...


Hi Christian, can you attach the full engine and vdsm log?  They may 
provide further clues about what went wrong.

Re: [ovirt-users] Live Storage Migration

[Greg Padgett]

On 09/14/2015 05:20 AM, Markus Stockhausen wrote:

Hi,

somehow I got lost about the possibility to do a live storage migration.
We are using OVirt 3.5.4 + FC20 Nodes (virt-preview - qemu 2.1.3)

 From the WebUI I have the following possibilites:

1) disk without snapshot: VMs tab -> Disks -> Move: Button is active
but it does not allow to do a migration. No selectable storage domain
although we have 2 NFS systems. Gives warning hints about
"you are doing live migration, bla bla, ..."

2) disk with snapshot: VMs tab -> Disk -> Move: Button greyed out

3) BUT! Disks tab -> Move: Works! No hints about "live migration"
I do not dare to click go ...

While 1/2 might be consistent they do not match to 3. Maybe someone
can give a hint what should work, what not and where me might have
an error.


Hi Markus,

Is this still relevant?  If so...

Live storage migration requires the following (from the code that 
determines if the "Move" buttons in 1/2 above are greyed or not):


 - cluster and dc version must be at least 3.2
 - vm must be stateful and up or paused
 - disk to migrate must be the active layer (ie not a snapshot)
 - disk images must be 'OK'

Is it possible one of these changed for the VM(s) in question?

Thanks,
Greg


Thanks.

[ovirt-users] moving storage away from a single point of failure

[Robert Story]

Hi,

I'm running oVirt 3.5 in our lab, and currently I'm using NFS to a single
server. I'd like to move away from having a single point of failure.
Watching the mailing list, all the issues with gluster getting out of sync
and replica issues has me nervous about gluster, plus I just have 2
machines with lots of drive bays for storage. I've been reading about GFS2
and DRBD, and wanted opinions on if either is a good/bad idea, or to see if
there are other alternatives.

My oVirt setup is currently 5 nodes and about 25 VMs, might double in size
eventually, but probably won't get much bigger than that.


Thanks,

Robert

[ovirt-users] Systemd-Script to put the node in "maintenance" on shutdown

[Luca Bertoncello]

Hi again,

I'm trying to write a systemd-script (for CentOS7) in order to automatically 
put the host in "maintenance" on shutdown and to activate it after boot.
I wrote a python-script that to that and it works so that I can start it and 
see the host in "maintenance" and having all VMs migrated.

Unfortunately I can't call this script on shutdown/reboot and wait until all 
VMs are migrated and the host is in maintenance.

Here my script:

[Unit]
Description=oVirt interface for managing host
After=remote-fs.target vdsmd.service multipathd.service libvirtd.service 
time-sync.target iscsid.service rpcbind.service supervdsmd.service 
sanlock.service vdsm-network.service
Wants=remote-fs.target vdsmd.service multipathd.service libvirtd.service 
time-sync.target iscsid.service rpcbind.service supervdsmd.service 
sanlock.service vdsm-network.service

[Service]
Type=simple
RemainAfterExit=yes
ExecStart=/usr/local/bin/ovirt-maintenance.sh active
ExecStop=/usr/local/bin/ovirt-maintenance.sh maintenance
KillMode=none

[Install]
WantedBy=multi-user.target

Could someone help me and say what I'm doing wrong?

Thanks a lot

Fedora/Centol/RHEL VMs:
   sudo yum install ovirt-guest-agent-common
   sudo systemctl enable ovirt-guest-agent.service && sudo systemctl start
ovirt-guest-agent.service

Windows guest tool for Windows VMs:
  ovirt 3.5:
 yum install ovirt-guest-tools
  ovirt 3.6:
 yum install ovirt-guest-tools-iso
To get the ISO, than import into your ISO storage domain and share to your
VMs to run the installer

Re: [ovirt-users] Automatically migrate VM between hosts in the same cluster

[Alex Crow]

Well, right now my problem is to understand how can I "simulate" this Power

GIven the outlay you will pay for your server kit regardless of using 
Ovirt or not, EUR 500 is nothing. As I said, what about ebay? I've just 
looked and there's a 24 outlet one for GBP 100, and an 8 port one for 
$44, both Buy It Now! And that's just a UK search.




By the way: I find really funny, that I can't define an Cluster with 
automatically migration of the VM without Power management. OK, I know what it 
can happens if the host is not really dead, but at least to allow that, with 
warnings and so on, should be nice...


Live migration works fine without power management. If a host gets too 
busy, VMs will migrate away from it.

[Christian Rebel]

Dear all,

 

I upgraded to 3.5.4.2-1.el7.centos, but I have still the Problem that I
can´t create  a snapshot!

Below some parts of the vdsm logs, does anyone have an idea to fix it,
please help...

Well, right now my problem is to understand how can I "simulate" this Power 
management. Maybe in the future, if we decide that oVirt  is the right solution 
for us, we will buy some Power management system (APC or similar).
But now, for the experiments, I can't ask my boss to pay >500€ for a device 
that maybe we will not use...

Hi Alex


2) My question was: "what can I do, so that in case of Kernel Panic or similar, the

You would make the VMs HA and acquire a fencing solution.

What do you mean now? Have two VM and build a cluster? This is not what we 
want...
If it's possible, I'd like to have more Host AS CLUSTER with migration of the 
VM between the nodes...
I think oVirt already do that, since I have to create Clusters. For me a Cluster is not 
just "more nodes with the same CPU", but also something with load balancing or 
high availability...


No, use the built in HA in Ovirt. Which requires a fencing solution. 
This means that if a host goes down the VMs on it will autostart on 
another host in the cluster. Yes, it's a cluster of *hosts*. In fact in 
the Ovirt Interface you can see "clusters" in the tree view!


We use the built in Ovirt HA for >200 VMs over 6 hosts and it works just 
fine. We lost a host fairly recently and only a couple of people (out of 
over 300) who use the services of a single VM noticed.


Ovirt also supports balancing the VM load across hosts. That is part of 
the cluster policy. You can also set affinity and anti-affinity of VMs. 
You can also have hosts actually migrate off VMs when they are idle and 
the host to power down to save on your electricity bill. When load on 
other hosts reaches a limit, the host will be powered back on and VMs 
will start migrating to it.



3) I'd like to have a shutdown-script on the host that put the host in 
Maintenance and wait until it's done, so that I can just shutdown or reboot it 
without any other action. Is it possible? It would help to manage the power

  > failure, too, assuming that other hosts have better UPS (it can be 
possible.)

You could probably use the REST API on the Ovirt Engine for that.But it might 
be better to have a highly available machine (VM or not) running something like 
Nagios or Icinga which would perform the monitoring of your
  hosts and connect to the REST API to perform maintenance and shutdown. You 
might also consider a UPS service like NUT (unless you're already doing it).

Well, I already use NUT and we have Icinga monitoring the hosts.
But I can't understand what you mean and (more important!) how can I do it...

I checked the REST API and the CLI. I can write a little script to put an host 
in Maintenance or active it again, that's not the problem.
The problem is to have somewhat starting this script automatically...

Any suggestion? Icinga will not be the solution, since it checks the host every 
5 minutes or so, but we need to have this script started in seconds...

Thanks

Mit freundlichen Grüßen

Luca Bertoncello


The rest is out of scope of Ovirt. Icinga was just a suggestion. You 
don't have to use it - but you can change the check interval for a check 
to whatever you want. I was just stating that you should be wary of 
running your checks/scripts from a host if what you are trying to 
trigger on is that host going down or having issues.


And if 5 minutes is too long maybe you need a bigger UPS? We have 1 hour 
battery runtime on ours at the moment (think it's a 160kVA central UPS 
offhand).

The documentation pages are contributed, so you are encouraged to ask for a
login and modify them when you have clarified the related aspects, so that
the learning curve could be shorter for others.
See the bottom of the page with "Log in / create account

Really? in the main page you have also:
High Availability Considerations

A highly available host requires a power management device and its fencing
parameters configured. In addition, for a virtual machine to be highly
available when its host becomes non-operational, it needs to be started on
another available host in the cluster. To enable the migration of highly
available virtual machines:

   - Power management must be configured for the hosts running the highly
   available virtual machines.
   - The host running the highly available virtual machine must be part of
   a cluster which has other available hosts.
   - The destination host must be running.
   - The source and destination host must have access to the data domain on
   which the virtual machine resides.
   - The source and destination host must have access to the same virtual
   networks and VLANs.
   - There must be enough CPUs on the destination host that are not in use
   to support the virtual machine's requirements.
   - There must be enough RAM on the destination host that is not in use to
   support the virtual machine's requirements.



What in particular is not clear and need better explanation?

Really, I don't think this documentation is good...
I read this page many times and try to understand how the program works, but I 
have many doubt...

In particular, the link you sent about HA: of course I read them and I 
configured the VMs with these settings, but really, I can't understand how can 
I set more host as a Cluster allowing automatically migration of the VMs when a 
host dies...
