can't mount an export domain with 4K block size (VDO) as PosixFS (xfs)
by thomas＠hoberg.net
After this (https://devconfcz2020a.sched.com/event/YOtG/ovirt-4k-teaching-an-old-dog-...)
I sure do not expect this (log below):
Actually I am trying to evaluate just how portable oVirt storage is and this case I had prepared a USB3 HDD with VDO, which I could literally move between farms to transport VMs.
Logical disks are typically large for simplicity within the VMs, QCOW2 and VDO assumed to compensate for this 'lack of planning' while the allocated storage easily fits the HDD.
Once I got beyond the initial issues, I came across this somewhat unexpected issue: VDO storage uses 4k blocks all around, but evidently when you mount an export domain (or I guess any domain) as POSIX, 512byte blocks are assumed somewhere and 4k blocks rejected.
I'd say that is a bug in VDSM, right?
Or is there anything in the mount options to fix this?

Promiscuous Mode
by Anton Louw
Hi All,
I would like to deploy a VM that will monitor a specific network. I know in VMware you can set the port group to allow Promiscuous Mode. Is there something similar I can do in oVirt?
Thanks

It seems 30 minutes... for timeout? About what, ansible job?
Or possibly implicit user session created when running the python script?
The snapshot has been correctly deleted (as I see also in engine.log), I
don't see it in webadmin gui.
Any known problem?
Just for test I executed again at 14:24 and I see same Ansible error at
14:54
The snapshot gets deleted, while the qemu-img command still continues....

and then continues until image copy completes, but at this time the job has
already aborted and so the completion of the ova composition doesn't go

How to extend timeout?

Hosted Engine stuck in Firmware
by Vinícius Ferrão
Hello, I’ve an strange issue with oVirt 4.4.1
The hosted engine is stuck in the UEFI firmware trying to “never” boot.
I think this happened when I changed the default VM mode for the cluster inside the datacenter.
There’s a way to fix this without redeploying the engine?

deprecating export domain?
by Charles Kozler
Hello,
I recently read on this list from a redhat member that export domain is
either being deprecated or looking at being deprecated
To that end, can you share details? Can you share any notes/postings/bz's
that document this? I would imagine something like this would be discussed
in larger audience
This seems like a somewhat significant change to make and I am curious
where this is scheduled? Currently, a lot of my backups rely explicitly on
an export domain for online snapshots, so I'd like to plan accordingly
Thanks!

shutdown virtual machine did not display in the list when using virsh list --all and virsh list --state-shutoff
by Kyre
Hello, I am using ovirt 4.3.8. I want to use the virsh command to boot the shutdown virtual machine, but when using virsh list --all and virsh list --state-shutoff, the shutdown virtual machine did not display in the list. What is the cause of this, and how can I display the shutdown virtual machine.

Ovirt Node 4.4.2 Engine Deployment - Notification Settings
by David White
I finally got oVirt node installed with gluster on a single node.
So that's great progress!
Once that step was complete...
I noticed that the Engine Deployment wizard asks for SMTP settings for where to send notifications. I was kind of surprised that it doesn't allow one to enter any credentials. It looks like this requires an unauthenticated local relay. I don't like that. :) See attached screenshot.
Has there been any talk about adding this into the wizard deployment?

Missing model_FLAGS on specific host
by Vinícius Ferrão
Hi,
I’ve an strange issue in one of my hosts, it’s missing a lot of CPU flags that oVirt seems to require:
[root@c4140 ~]# vdsm-client Host getCapabilities | egrep "cpuFlags|cpuModel"
"cpuFlags": "ssse3,mca,ept,pdpe1gb,vmx,clwb,smep,msr,acpi,pge,sse4_2,nopl,cqm_mbm_total,cx16,avx512vl,aperfmperf,xsaves,3dnowprefetch,nonstop_tsc,cmov,mce,intel_pt,avx512f,fpu,pku,tsc,sdbg,erms,pse36,md_clear,apic,sse,pcid,clflushopt,xtopology,pts,monitor,vpid,cpuid,hle,mba,ss,cqm,avx2,ibpb,xgetbv1,flush_l1d,mmx,epb,pti,fxsr,dca,nx,syscall,stibp,mtrr,cx8,sse2,avx,sep,intel_ppin,lm,tm,bts,adx,bmi1,smx,popcnt,pclmulqdq,lahf_lm,mpx,rdseed,cqm_llc,avx512cd,cdp_l3,f16c,invpcid,fsgsbase,cpuid_fault,tm2,smap,dts,pse,xsave,sse4_1,constant_tsc,pat,tsc_deadline_timer,vnmi,avx512dq,dtes64,xsaveopt,ida,pdcm,tpr_shadow,pln,de,x2apic,avx512bw,pae,rdrand,clflush,rdtscp,art,cqm_mbm_local,pebs,ssbd,movbe,pbe,tsc_adjust,vme,ht,est,bmi2,cat_l3,dtherm,ospke,rdt_a,aes,ibrs,rep_good,fma,xtpr,ds_cpl,abm,xsavec,invpcid_single,flexpriority,cqm_occup_llc,pni,rtm,arat,arch_perfmon",
"cpuModel": "Intel(R) Xeon(R) Gold 6130 CPU @ 2.10GHz",
In a properly working host it have flags like those ones:
model_Westmere-IBRS,model_kvm32,model_core2duo,model_Opteron_G1,model_Broadwell,model_qemu64,model_Broadwell-noTSX,model_Nehalem-IBRS,model_Haswell-IBRS,model_pentium2,model_Broadwell-IBRS,model_Haswell-noTSX,model_Haswell,model_Haswell-noTSX-IBRS,model_Conroe,model_pentium,model_n270,model_Nehalem,model_IvyBridge-IBRS,model_kvm64,model_SandyBridge,model_pentium3,model_Broadwell-noTSX-IBRS,model_qemu32,model_486,model_IvyBridge,model_SandyBridge-IBRS,model_Westmere,model_Penryn,model_Opteron_G2,model_coreduo",
But in this machine it’s totally missing. I know this model_ flags are an oVirt thing, since they aren’t default on the CPUs.
The host machine is a Dell C4140 compute node, the firmware is fully updated, so I’ve done the basic to figure out what’s happening.
Thanks,

ovirt 4.4 self-hosted deployment questions
by Michael Thomas
I have not been able to find answers to a couple of questions in the
self-hosted engine documentation[1].
* When installing a new Enterprise Linux host for ovirt, what are the
network requirements? Specifically, am I supposed to set up the
ovirtmgmt bridge myself on new hosts, or am I supposed to let that be
handled by the engine when I add the new host to the engine?
* In the 'New Host' dialog on the engine management page, does the
Hostname/IP that I enter have to be the host's name on the ovirtmgmt
LAN? If so, then it seems to me that I need to configure the ovirtmgmt
bridge myself on new hosts.
* Does the engine need to be able to route outside of the cluster (eg to
the WAN), or is it allowed to restrict the engine's routing to the local
cluster?
* In the 'New Host' dialog on the engine management page, what is the
meaning of 'Choose hosted engine deployment action'? From the way it is
phrased, it sounds like this will create a second engine in my cluster,
which doesn't make sense. Or does this mean that the new host will be
able to run the Engine VM in a HA manner?
In my current test deployment I have 3 subnets in my cluster. Network
WAN is the WAN. Network CLUSTER is for communication between cluster
compute nodes, storage servers, and management servers. Network OVIRT
is for ovirt management and VM migration between hosts.
My first self-hosted engine host is connected to networks CLUSTER and
OVIRT. The engine VM is only connected to network OVIRT through a
bridge on the host, but has a gateway that lets it route traffic to
network CLUSTER (but not network WAN).
Is this an appropriate network setup for ovirt, or should there be no
distinction between the CLUSTER and OVIRT networks?
