Any real experiences with nested virtualisation?
by tonyppe＠gmail.com
I have ovirt 4.3.5 and Openstack hosts. There are 2 x openstack compute and 2 x ovirt hosts with hosted manager. I think i can simplify the management of this if I were to virtualise the openstack compute nodes as VMs on ovirt.
I wanted to reach out here to gauge any other users experiences with it if at all. From the research I have done it looks like from the VM perspective, migration must not be allowed.
Any info / comments / feedback appreciated.

Re: Cannot Increase Hosted Engine VM Memory
by Dionysis K
Now i noticed another strange i deactivated the memory balloon option from
the VM hosted engine and tried to update the values again with the same
memory it still keeps the value of memory size at 5120 while the value of
physical memory guaranteed it changed to what we desire at the 8192 value
and then the error appears again in the vm engine
i ckecked the engine log file it shows the same errors!
is there are other logfile locations that can give us any clues ?

Yes, I do. Gold crown indeed.
It's the "HostedEngine" as seen attached!

Hi Simone
Can I get help with this issue? Still cannot increase memory for Hosted Engine.
From the logs it seams that the engine is trying to hotplug memory to the engine VM which is something it should not happen.
The engine should simply update engine VM configuration in the OVF_STORE and require a reboot of the engine VM.
Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?

Sorry for accidental send.
Anyway I try to increase physical memory however it won't go above 4096MB. The hypervisor has 64GB.
Do I need to modify this value with Hosted Engine offline?
No, it's not required.
Can you please attach your engine.log for the relevant time frame?

iSCSI Multipath/multiple gateways
by dan.poltawski＠tnp.net.uk
My iSCSI target (ceph-based) has multiple gateways, I’d like to ensure my hosted storage is aware of these such that each gateway can be rebooted for maintance without impacting service. What is the appropriate way to configure this so that each host knows of the multipath configuration? I do not have multiple network paths, just multiple gateways on the same network, so I think the multipath UI tool isn’t the way to do this.
Any help/docs pointers appreciated.

the virtual machine crushed and I cant shutdown the vm successfully

Dear ovirt developers:
The trouble bothered me for a long time;Some times my vm will crush and I cant shutdown it,I had to reboot the ovirt-node to slove it;
the vm's error below
The ovirt-node's error below
The vm's threading on the ovirt-node, the IO ratio is 100%
and the vm's process change to defunct
I can not kill it,every time I had to shutdown the ovirt-node
on the engine website ,the vm's status always in the way to shutdown ,even if I wait for it for hours;
It either failed or is shutting down
and the "power off" cant shutdown the vm too.

engine.log flooded with "Field 'foo' can not be updated when status is 'Up'"
by Matthias Leopold
Hi,
I updated my production oVirt environment from 4.3.3 to 4.3.5 today.
Everything went fine so far, but there's one annoying phenomenon:
When I log into the "Administration Portal" and request the VM list
("/ovirt-engine/webadmin/?locale=en_US#vms") engine.log is flooded with
lines like
WARN [org.ovirt.engine.core.utils.ObjectIdentityChecker] (default
task-10618) [54d8c375-aa72-42f8-876e-8777d9d1a08a] Field
'balloonEnabled' can not be updated when status is 'Up'
"Field", task and UUID vary and the flood stops after a while. Also
listing or trying to edit other entities seems to trigger this "storm"
or loop over and over again to a point that log file size is becoming an
issue and interface is becoming sluggish. I can also see that CPU usage
of engine java process goes up. When I log out everything is quiet and
"VM Portal" is not affected at all.
I have seen lines like that before and know that they are usually OK
(when changing VM properties), but these logs used to be linked to
singular events. I suspect that the present behaviour might be linked to
VMs that have "Pending Virtual Machine changes", which are in most cases
"Custom Compatibility Version" changes that still stem from the upgrade
to Cluster Version 4.3. I can't be sure and I can't resolve all these
pending changes now, but these should not be causing such annoying
behaviour in the first place.
I resorted to setting engine log level to "ERROR" right now to at least
stop the log file from growing, but this not a solution. I can still see
CPU load going up when using the interface. I very much hope that
someone can explain whats happening and tell me how to resolve this.
thanks a lot
Matthias
