Why this enforcing? If the VM is so important I see it as a limitation not
to be able to move it in case of need


It's related to CPU pinning and NUMA.

Tested with Oracle RDBMS and not used in my case.


In the specific case of Oracle, I actually suspect you must use CPU pinning
for licensing reasons. I suggest you check.

As for CPU passthrough, might depend on which features you use.

Do you think NUMA so essential? It implies non-migratable VM...
In my tests I didn't set NUMA


Depends on the workload really. It and CPU pinning are many times critical
for IO bound workloads. Also depends on how much optimization you are
after.

In my opinion the  main limitation of "High performance VM" is to be
not-migratable (probably implied because you set NUMA?)
In that case could it be possible to have NUMA as choice, so that at the
same time you can choose if you want a migratable or not-migratable high
performance VM?
Also CPU passthrough, I don't remember if it is included/fixed option in
high perf VM...

Re: [ovirt-users] VirtIO-SCSI and viodiskcache custom property

Hi,

is there a reason why the viodiskcache custom property isn't honored when
using VirtIO-SCSI?

On a Cinder (Ceph) disk "viodiskcache=writeback" is ignored with
VirtIO-SCSI and honored when using VirtIO.

On an iSCSI disk "viodiskcache=writeback" is ignored with VirtIO-SCSI and
the VM can't be started when using VirtIO with "unsupported configuration:
native I/O needs either no disk cache or directsync cache mode, QEMU will
fallback to aio=threads"

We actually want to use "viodiskcache=writeback" with Cinder (Ceph) disks.


That's because on block storage we use native io and not threads. I assume
the hook needs to change to use native io in this case.

[ovirt-users] All in one adds host failure

2018-01-20 Thread Pym 
Hi:


I'm doing ovirt all in one. I first used the iso of node to do the basic 
environment, and then I did the source compilation and installation ovirt on 
the node environment. When I add a New Host to the web interface Host- >New, in 
the log: Ansible playbook command has exited with value: 1, then Host 
installation failed.


The logs are as follows:

What am I going to do now to add host success?

Thanks, Fred.
I have been looking at FCoE VDSM Hooks to no help. Looking at it again, I am 
still not able to see any FCoE 
[root@ovirtengine ~]# engine-config -g

I finally managed to find the "custom Property" where I could set 
"enable=yes,dcb=no" for fcoe, but when applying the change, I get unexepected 
error. Yes, the host was in local maintenance mode when I applied the change.
I am afraid I am not understanding all the steps needed from the Virtual

Should I add a new FCoE only network interface and should this have VLAN/IP 
address in a special range compared to the internal network in the rack?
Thanks again.
