Re: [ovirt-users] Importing existing KVM hosts to Ovirt

[Shahar Havivi]

I am glad its works.
btw the vdsm user is exists you can see it in /etc/passwd but it have no
shell login so the ssh key generation will be in /var/ (which mean it may
not survive reboot).
the instruction for the ssh are for Xen but the instruction in the section
"importing-vm" are working for kvm as well.

Re: [ovirt-users] massive simultaneous vms migrations ?

[Konstantin Shalygin]

Hello.

What is your Migration Network?



We have some hosts that have 60 vms. So this will create a 60 vms migrating 
simultaneously.
Some vms are under so much heavy loads that migration fails often (our guess is that 
massive simultaneous migrations does not help migration convergence) - even with 
"suspend workload if needed" migraton policy.

[ovirt-users] PXELinux BIOS reboot loop on Ubuntu 16.04

[Matt .]

When I have build a successfull host using Foreman it gets the PXE
Menu showed in the attachment.

This menu with the first option selected gets into a reboot loop:

Chanload into bootloader on the first disk




When I manually switch to:

Chanload into bootloader on the first disk - alternative


the host boots as normal.

Why does this happens just at once on Debian/Ubuntu and not on Fedora/CentOS ?

Re: [ovirt-users] Best Storage Option: iSCSI/NFS/GlusterFS?

[Bryan Sockel]

Was reading over this post to the group about storage options.  I am more of 
a windows guy as appose to a linux guy, but am learning quickly and had a 
question.  You said that LACP will not provide extra band with (Especially 
with NFS).  Does the same hold true with GlusterFS.  We are currently using 
GlusterFS for the file replication piece.  Does Glusterfs take advantage of 
any multipathing?

Thanks

Hi Everyone,

  I'm about to setup an oVirt cluster with two hosts hitting a Linux storage 
server.  Since the Linux box can provide the storage in pretty much any 
form, I'm wondering which option is "best." Our primary focus is on 
reliability, with performance being a close second.  Since we will only be 
using a single storage server I was thinking NFS would probably beat out 
GlusterFS, and that NFSv4 would be a better choice than NFSv3.  I had 
assumed that that iSCSI would be better performance wise, but from what I'm 
seeing online that might not be the case.

NFS 4.2 is better than NFS 3 in the sense that you'll get DISCARD support, 
which is nice.
Gluster probably requires 3 servers.
In most cases, I don't think people see the difference in performance 
between NFS and iSCSI. The theory is that block storage is faster, but in 
practice, most don't get to those limits where it matters really.


  Our servers will be using a 1G network backbone for regular traffic and a 
dedicated 10G backbone with LACP for redundancy and extra bandwidth for 
storage traffic if that makes a difference.

LCAP many times (especially on NFS) does not provide extra bandwidth, as the 
(single) NFS connection tends to be sticky to a single physical link.
It's one of the reasons I personally prefer iSCSI with multipathing.


  I'll probably try to do some performance benchmarks with 2-3 options, but 
the reliability issue is a little harder to test for.  Has anyone had any 
particularly bad experiences with a particular storage option?  We have been 
using iSCSI with a Dell MD3x00 SAN and have run into a bunch of issues with 
the multipath setup, but that won't be a problem with the new SAN since it's 
only got a single controller interface.

A single controller is not very reliable. If reliability is your primary 
concern, I suggest ensuring there is no single point of failure - or at 
least you are aware of all of them (does the storage server have redundant 
power supply? to two power sources? Of course in some scenarios it's an 
overkill and perhaps not practical, but you should be aware of your weak 
spots).

I'd stick with what you are most comfortable managing - creating, backing 
up, extending, verifying health, etc.
Y.

Interesting idea!

The only issue I see if not having a way to tell if the file system was actually
unmounted. Does process termination guarantee that the file system was
unmounted?

You can double check that by deactivating underlying LV. It should not be busy.

As I understand it unmounts FS as soon as all inodes are closed. Since killing 
of process is closing all open inodes, you can be sure that file system is 
unmounted if there are no other processes. Of course this is a place for race 
conditions. For example, unmounting can be stuck some time if underlying 
storage is unresponsive. Multipath should drop all IOs with EIO. VDSM has to 
wait enough time after acquiring the lock before mounting masterfs.

Do you know if the behaviour is documented somewhere?

umount(8):

-l, --lazy
Lazy unmount.  Detach the filesystem from the filesystem hierarchy now, and 
cleanup all references to the filesystem as soon as it is not busy anymore.  
(Requires kernel 2.4.11 or later.)

​Hi,

please take a look at man page of fence_ipmilan agent, there are 2 types of
options:

1. Command line options like '-L'
2. Stdin options like 'privlvl'

For 'Options' field of power management agent in oVirt you need to use
stdin options, so please add 'privlvl=operator' into Options as already
Gianluca suggested

Re: [ovirt-users] massive simultaneous vms migrations ?

[ovirt-users] Question about Huge Pages

[Gianluca Cecchi]

Hello,
I'm testing virtualization of some Oracle servers.
I have 4.1.1 with CentOS 7.3 servers as hypervisors.
Typically on physical Oracle servers I configure huge pages for Oracle
memory areas.
In particular I disable Transparent Huge Pages, because they are known to
be in conflict with Oracle performances, both in RAC and in standalone
configurations.
In RHEL systems I configure "transparent_hugepage=never" boot parameter,
while in Oracle Linux OS uek kernels it is already disabled by default.
I notice that in CentOS 7.3, by default, transparent huge pages are
configured:

[root@ov300 ~]# cat /proc/meminfo | grep -i huge
AnonHugePages:  17006592 kB
HugePages_Total:   0
HugePages_Free:0
HugePages_Rsvd:0
HugePages_Surp:0
Hugepagesize:   2048 kB
[root@ov300 ~]#

I'm going to configure a VM with 64Gb of ram and with an Oracle RDBMS that
would have 16Gb of SGA.
I suspect that I could have problems if I dont' change configuration at
hypervisor level...

What do you think about this subject?
Is there any drawback if I manually configure the hypervisors to boot with
 the "transparent_hugepage=never" boot parameter?

Thanks in advance,
Gianluca

Yes, "-1" means "autoallocation from libvirt".
I don't see obvious issues in this XML, and, most importantly, one
invalid XML should never cause libvirtd to segfault.

I'd file a libvirt bug.

 If it fails, try upgrading ovirt-hosted-engine-ha on the

fixed (https://bugzilla.redhat.com/show_bug.cgi?id=1364132
).
 After upgrade and restart of the vm, this should work, and
you should be able to connect to the console.
3. On the hosted engine host look at the content of:
/var/run/ovirt-hosted-engine-ha/vm.conf
Does it contain a graphical device? Or a console device?

Re: [ovirt-users] Storage latency message

Once upon a time, Nir Soffer  said:

I don't see any evidence that the storage was having any problem.  The
times the message gets logged are not at any high-load times either
(either scheduled backups or just high demand).

I wrote a perl script to replicate the check, and I ran it on a node in
maintenance mode (so no other traffic on the node).  My script opens a
block device with O_DIRECT, reads the first 4K, and closes it, reporting
the time.  I do see some latency jumps with that check, but not on the
raw block device, just the LV.

By that I mean I'm running it on two devices: the multipath device that
is the PV and the metadata LV.  The multipath device latency is pretty
stable, running around 0.3 to 0.5ms.  The LV latency is higher (just a
little normally) but has a higher variability and spikes to 50-125ms (at
the same time that reading the multipath device took under 0.5ms).

Seems like this might be a problem somewhere in the Linux logical volume
layer, not the block or network layer (or with the network/storage
itself).

Hi,
this works for me in options part of host power mgmt configuration with

thx, that solved it (privlvl=OPERATOR in my case)

Re: [ovirt-users] vm "maximum memory" setting questions

[Nelson Lameiras]

Hello michal, 

Thanks for your answers. 
If others have same questions, I did found this information below on oVirt web 
site 
(http://www.ovirt.org/develop/release-management/features/engine/maximum-memory-size/)
 
Note on size of maximum memory 


If memory hot-plug is not required, max memory can be set to be the same as VM 
memory. Suggested value is 4x size of VM memory. Larger max memory is 
discouraged because: 

* I can make QEMU process to start for longer time. 
* If hot plugged memory is also required to be hot unpluggable, it needs to 
be considered as movable by the guest kernel. Kernel requires the amount of 
movable memory to be at most 4x larger that non-movable memory for stable run. 
* On PowerPC platform continuous block of non-movable memory of size 1/64 
of the max memory needs to be allocated for each VM. 

cordialement, regards,

You don’t have to decide, you can keep the default 4x. 
For CPUs it is not currently needed and is set according to engine-config

for more info about setting the vdsm user you can see this section:
https://www.ovirt.org/develop/release-management/features/virt/XenToOvirt/#importing-vm
its for importing from Xen hypervisiors but the ssh generation for vdsm
user is the same.

You could edit the storage connection via the API (perhaps the 'force'
attribute is needed).

can you run that as a “vdsm” user? You need to exchange keys for “vdsm” (note 
it has disabled login, so you need to use "runuser" or something)

[ovirt-users] impossible to change console graphics on hosted engine

[Nelson Lameiras]

Hello, 

My hosted engine has currently VNC (+cirrus) graphics console, which has 
serious performance issues with my remote-viewer (theses issues are not 
important for this mail) 

I know that SPICE (+QXL) works perfect for me, so I tried to update my 
hostedEngine console settings on oVirt GUI, but I get the message below : 

"There was an attempt to change Hosted Engine VM values that are locked" 

So my question is : how can I change this setting on HostedEngine? 

This question could be applied to other settings wich I would like to also 
change on HostedEngine but are also locked (ex: "optimise for

In general, when VDSM acquires an interface, it marks its ifcfg file and
some logic exists around that. I'm not sure if this is the case here, but
it may explain what you saw.
If the ifcfg file is now identified as 'acquired' it will be overwritten
with the config VDSM supports.
Networks are attached to nics or bonds, the way to assign a network to a
specific VLAN is to create a VLAN network (mentioning the TAG) as you have
done. The logic behind this is to allow the user to create multiple
networks on the same nic/bond as long as they do not collide (in terms of
vlan ids), letting oVirt handle the vlan interface creation behind the
scene.

When you create a network, even if its infrastructure already partially
exists (the vlan iface), it will tear down the configuration and create it
again.
This is especially true when originally there was no bridge and now one
needs to be added.
You could try to create a non-VM network (remove the VM check-box), which
does not add a bridge, perhaps that will help.

Please let us know if you still see this problem with 4.0 or 4.1.

Thanks,
Edy.

Re: [ovirt-users] Ovirt 4.0 to 4.1 CentOS7.3 and libvirtd 2.0.0 segfault issue

[Yanir Quinn]

Hi Rafal
not sure it relates to your issue, but i experienced a similar issue with
segfault (running on fedora 25)
to resolve it i had to remove glibc packages and then install them again
(maybe a same workaround for libvirt will do the job here)

Re: [ovirt-users] Latency threshold between Hosted Engine and Hosts

[Piotr Kliczewski]

Fernando,

We use heartbeats to understand health of the connection. Potentially
you may see heartbeat exceeded exceptions
so you may want to increase vdsHeartbeatInSeconds. I would not change
it in advance but as you see the issue
and slowly increase the value.

Thanks,
Piotr

Re: [ovirt-users] [oVirt 4.1] oVirt installation and hotplug memory to the hosted-engine VM

[Martin Sivak]

> can the force-download be disabled

I will defer to Simone here

> 2 - Can we hotplug memory on the hosted-engine VM? if yes how?

We do not support hotplug. However, editing the VM in webadmin should
trigger a sync that distributes the new settings to all hosted engine
nodes. This might take a minute in normal case. A VM restart will then
pickup the new values.

Please attach the engine.log from the engine machine and agent log
from HE node if this does not work for you.

Best regards

[ovirt-users] Change DNS Server

[Kai Wagner]

Hi,

where can I change the dns server for my hosts? I know the DNS entry is
part of the ifcfg-* file, but I tried to change it there and after a
reboot the old entry was restored from anywhere.

Hello Fernando,

There is no known problem with such delay figures.
The heartbeat to the hosts is of several seconds.

Thanks,

Re: [ovirt-users] Empty ovirt engine web pages

[Maor Lipchuk]

Hi Shubham,

In case you do not need the DWH setup, you can disable the Dashboard
background queries via the ovirt-engine.conf.

Please, add the following file to your $DEV_OVIRT_PREFIX folder:
 "$DEV_OVIRT_PREFIX/etc/ovirt-engine/engine.conf.d/99-no-dashboard.conf"
and add it the following content:

 #
 # Enable/disable updating the dashboard DB query caches at regular
intervals.
 #
 DASHBOARD_CACHE_UPDATE=false

This should stop the error message

Regards,
Maor

Yes, "-1" means "autoallocation from libvirt".
I don't see obvious issues in this XML, and, most importantly, one
invalid XML should never cause libvirtd to segfault.

I'd file a libvirt bug.

Re: [ovirt-users] Importing existing KVM hosts to Ovirt

[Shahar Havivi]

Hi,
There is a wiki page for importing VMs from other hypervisors here:
https://www.ovirt.org/develop/release-management/features/virt/virt-v2v-integration/

and specific for KVM from Libvirt the wiki page is in progress but you can
read about it here:

ovirt-host-deploy requires otopi, and also engine-setup (from the engine
git repo) does. So unless you want to start manually imitating what these
do (which might not be a terrible idea, if you want to understand more
deeply how things work, but will take more time), you do need otopi.

Also please note that the above developer guide is probably not complete
or up-to-date - please check also README.adoc from the engine sources.

Indeed, patches are welcome :-)

I expect at least some packages to be missing there, didn't check
personally.

which ones? postgresql's? It's automatically done when you install
from RPMs, but not in dev-env mode. So you'll have to do that
manually for now.

Re: [ovirt-users] Ovirt 4.0 to 4.1 CentOS7.3 and libvirtd 2.0.0 segfault issue

[Rafał Wojciechowski]

hello,

I made comparison(+diff) between xml passing through vdsm which is 
working and another one which cause libvirtd segfault


https://paste.fedoraproject.org/paste/eqpe8Byu2l-3SRdXc6LTLl5M1UNdIGYhyRLivL9gydE=

(I dont have so much ram and vgamem)

hello,

I extracted xml from /var/log/core for some test VM and tried to 
validy via virt-xml-validate

maybe it could help in this case

hi,

I will add few informations:

currently I am using:

libvirt-daemon-kvm-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-qemu-2.0.0-10.el7_3.5.x86_64
qemu-kvm-ev-2.6.0-28.el7_3.6.1.x86_64
ovirt-engine-4.1.1.8-1.el7.centos.noarch(I tried update, to see if it 
will help but nothing has changed)


same problem exists with SELinux and without SELinux(now it is in 
permissive mode; after the reboot)

Rafal Wojciechowski
