[ovirt-users] Re: Multiple GPU Passthrough with NVLink (Invalid I/O region)

2020-09-14 Thread Arman Khalatyan
any progress in this gpu question?
in our setup we have supermicro boards with intel xeon gold 6146 + 2 T4
we add extra line in the /etc/default/grub
"rd.driver.blacklist=nouveau nouveau.modeset=0 pci-stub.ids=xxx:xxx
intel_iommu=on"
would be interesting if the nvlink was the showstopper.

[ovirt-users] Re: oVirt thrashes Docker network during installation

2020-04-12 Thread Arman Khalatyan
i think it wouldn't work out of box
ovirt will overwrite all your routes and network. you might try to tell
ovirt do jot maintain the network of a interface where you got a docker and
also add custom rules in the firewall ports template on the engine.

Hello,
any successful stories of the Nvidia T4 usage with the Ovirt?
I was wondered if one would get 2 hosts each with T4s , are there  live
migrations possible?
thanks,

[ovirt-users] Re: VM incremental backup

2019-05-14 Thread Arman Khalatyan
The sparse files are special files(please checkout the wiki pages) to
conserve some diskspace and copy time.
The rsync --sparce does not take an advantage of it. It is trying to
checksum whole virtual diskspace which is obviously zero filled.
If you "cp" file then "cp" will try to autodetect it otherwise your file
willbe converted to regular file. You can also copy files with "tar -S ".
To check the size of actual vs virtual(sparse) you can use:
df -bsh filename vs  df -sh

[ovirt-users] many 4.2 leftovers after upgrade 4.3.3

2019-05-02 Thread Arman Khalatyan
Hello everybody,
after the upgrade of ovirt-engine node I have several packages still
pointing from 4.2 repo.
Actually everything is working as expected.
yum clean all&& yum upgrade does not find any updates, but reinstall
bringing same packages from the 4.3 repo
for example:





























*yum reinstall safelease.x86_64  Loaded plugins: changelog, fastestmirror,
langpacks, vdsmupgrade, versionlockRepository centos-sclo-rh-release is
listed more than once in the configurationLoading mirror speeds from cached

i think this path should work as well:  4.1.8-> 4.2.8-> 4.3.3
may be ovirt devs should confirm that.
do you have a hosted-engine or gluster enabled?
good luck,

[ovirt-users] Trouble to update the ovirt hosts (and solution)

2018-10-02 Thread Arman Khalatyan
Current cocpit packages are conflicting, which is preventing the host update:

Transaction check error:
  file /usr/share/cockpit/networkmanager/manifest.json from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch
  file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch


Looks like a current packaging of cocpit is wrong, it doesn't upgrade
existing version.
To solve it simply:
yum remove cockpit-networkmanager-172-1.el7.noarch

yum clean ;yum update
all fixed.

[ovirt-users] Re: Connection issues when using gluster + infiniband + RDMA

2018-08-13 Thread Arman Khalatyan
try to leave datagramm mode, do not change mtu.  it looks
like gluster is connected over the tcp/ipoib. you might get packets drops
with mtu> 2k. as i remember you should tune your ib switch for the mtu
size,at least on the mellanox managed switch.

if the gluster connected over rdma it should not use any of tcp settings.
Is your mount -l shows that the gluster mounted with .rdma?

btw opensm should run only once, the others are going to stay in the
standby mode.

I know at one time there was an issue created to make this work through
virtio.  I mean, it was back in the early 3.x days I think.  So this might
be possible now (??).  Passthrough LUN?

you should download microcode from the intel web page and overwrite the
/lib/firmware/intel-ucode or so...please check the readme.

Hello,
nice to see integration of Spectre-Meltdown info in 4.1.9, both for guests
and hosts, as detailed in release notes:

I have upgraded my CentOS 7.4 engine VM (outside of oVirt cluster) and one
oVirt host to 4.1.9.

Now in General -> Software subtab of the host I see:

Am I supposed to manually set any particular value?

If I run version 0.32 (updated yesterday) of spectre-meltdown-checker.sh I
got this on my Dell M610 blade with

A false sense of security is worse than no security at all, see --disclaimer

So it seems I'm still vulnerable only to Variant 2, but kernel seems ok:

  * Kernel is compiled with IBRS/IBPB support:  YES

while bios not, correct?

Is RH EL / CentOS expected to follow the retpoline option too, to mitigate
Variant 2, as done by Fedora for example?

Re: [ovirt-users] Are Ovirt updates nessessary after CVE-2017-5754 CVE-2017-5753 CVE-2017-5715

2018-01-15 Thread Arman Khalatyan
If you see that after the update of your OS dmesg shows RED alert in
the spectra check script in the second position then you should follow
the intel's read.me.
As in readme described on Centos 7.4:
rsync  -Pa intel-ucode /lib/firmware/
On the recent kernels(>2.6.xx) the dd method does not work, dont do that.
To confirm that microcode loaded:
dmesg | grep micro
look for the release dates.
But I beleve that v4 should be already in the microcode_ctl package of
the CentOS7.4 ( in my case 2650v2 was not inside, but the  v3 and v4
were there)
I have a script to enable or disable the protection so you can see the
performance impact on your case:

if you have recent supermicro you dont need to update the bios,
Some tests:
Crack test:
https://github.com/IAIK/meltdown

Check test:

the intel microcodes  you can find here:

hi Sahni,

Looks like the live storage migration might fail on the heavy loaded

"! moving following disks when VM is running", if we press "ok ! do it" what
are the consequences? it is not explained in the docs.
thank you beforehand

Hi Arman,
VM's migration and disks migration are two different things:

- Live storage migration:
A VM's disk can be moved to another storage domain while the VM is running,
by copying the disk's structure the destination domain.
The hard part of live storage migration is moving the active layer volumes
from one domain to another, while the VM is writing to those volumes.
By using a replication operation, the data is written to both source and
destination volumes.
When both volumes contain the same data, the block job operation can be
aborted, pivoting to the new disk.

You may find more detailed information here: https://www.ovirt.org/develop/
release-management/features/storage/live-storage-migration-between-mixed-
domains/

- Live migration:
Provides the ability to move a running virtual machine between physical
hosts with no interruption to service.
The virtual machine remains powered on and user applications continue to
run while the virtual machine is relocated to a new physical host.
A running virtual machine can be live migrated to any host within its
designated host cluster.
Live migration of virtual machines does not cause any service interruption.

You may find some more information here: https://access.redhat.com/
documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/
html/Administration_Guide/sect-Migrating_Virtual_
Machines_Between_Hosts.html#What_is_live_migration

Hope it helps!

[ovirt-users] Ovirt 4.2pre Moving disks when VM is running

2017-11-24 Thread Arman Khalatyan
hi,
I have some test enviroment with ovirt
"4.2.0-0.0.master.20171114071105.gitdfdc401.el7.centos"
2hosts+2NFS-domains

During the multiple disk movement between the domains I am getting this warning:
Moving disks while the VMs are running.(this is not so scary red as in
4.1.x :) )

What kind of problems can happen during the movement?

Thanks,

For the moment QoS is unlimited.
Actually for some tasks I wish to allocate 80% of 10Gbit interface,
but the VM interface is always 1Gbit.
Inside the QoS of the host interface I cannot put 8000 for the Rate
Limit, it claims that rate limit should be between number 1...1024,

hi Yaniv,
yes for sure I hit some cache in between but not the vm cache, it has a 4GB
ram, with oflag=direct I get about 120MB/s

for the data analysis the cache is our friend:)

The backend is a lustrefs 2.10.x.
yes we have dedicated 10G on the hosts, where we can limit the vm interface
to 10Gbit?

Hi, in our environment we got pretty good io performance on VM, with
following configuration:
lustrebox: /lust mounted on "GATEWAY" over IB
GATEWAY: export /lust as nfs4 on 10G interface
VM(test.vm): import as NFS over 10G interface

[r...@test.vm  ~]# dd  if=/dev/zero bs=128K count=10

only one problem remains that on heavy io I get some wornings that the vm
network is saturated, are there way to configure the bandwidth limits to
10G for the VM Interface??

Hi,
Is this document still valid?

https://www.ovirt.org/develop/release-management/features/storage/vm-leases/

If yes, I have a n question concerning the local SSD leases:
If the HA leases are going to the local host ssd storage, then due to
the Master Domain failure the HA will continue to run?
Or in which scenario external leases are helping to keep HA VM up and running?

Re: [ovirt-users] [ANN] oVirt 4.2.0 First Beta Release is now available for testing

2017-11-02 Thread Arman Khalatyan
I just tested the new 4.2, looks new shiny UI, thanks.

I would like to join to Jiris statement, ovirt should become more
stable, clean and useful.
The right or left clicks  or UI designs, mobile friendly or not,those
futures are the secondary tasks for me.
For those who would like to manage the vms from the mobile devices
they can use mOvirt app.
I wish that the development team will concentrate on the main
advertised futures to make them stable.
as a user I wish that the following points can make it stronger:
- please make a ovirt as a  FULL HA solution
- one of the weak points of the ovirt is a spm, this should go away in
the first point, not the right click one:).
- hosts management like a foreman, but without foreman.
- strong solution with a multirail HA storage
- move hosts complete to disk-less infrastructure, easy to scale-up
- scheduled backup solution integrated in the gui/api
- reasonable reports,( similar like dwd in 3.6)
Most of the points are almost done, but we have always hire or there
half-solved problems.

 Short answer: No, we removed it on purpose.

 Long answer: No, here are the reasons why:
 - We are attempting to get the UI more mobile friendly, and while
 its not 100%
 there yet, it is actually quite useable on a mobile device now.
 Mobile devices
 don't have a right click, so hiding functionality in there would
 make no

 - You can now right click and get the browsers menu instead of
 ours and you
 can do things like copy from the menu.
 - We replicated all the functionality from the menu in the
 buttons/kebab menu
 available on the right. Our goal was to have all the commonly
 used actions as
 a button, and less often used actions in the kebab to declutter
 the interface.
 We traded an extra click for some mouse travel

Re: [ovirt-users] Sync two Nodes

2017-11-02 Thread Arman Khalatyan
Yes, if you configure the cluster with networks /storage/etc  you can
put off the second node to save power:) and loose HA, but every time
when you change some thing in a  main node  you should turn on second
one and reinstall it.
Healthy node means that ovirt-engine can see that host has a access to
storage and all networks are available in order to start the failed
VM.
The HA function can be configured per VM, and the action what engine
should trigger on failure: reboot, pause or poweroff you can choose in
the vm settings.

Re: [ovirt-users] Sync two Nodes

2017-11-02 Thread Arman Khalatyan
Ovirt HA means that if you have virtual machine running on the ovirt
environment(let us say 2 nodes) then if the bare metal gets troubles,
VM will be restarted on the second one, the failed host must be
fenced: poweroff/reboot, but the HA model assumes that the both bare
metal machines are always on and healthy.  if second host is off, then
simply you dont have HA, you should ask someone  to turn on the second
host in order to rerun your VMs.:)
Usually if you turn off the "healthy host"  it does not have any
information to sync,  the ovirt-engine manages all things.


(Maybe question belongs to the wrong forum?)
The ovirt does not contain any sync / HA functionality in the data side.
Maybe you are looking for some ha/failover-file systems like a
glusterfs(geo-replication) or drbd(real-time replication) or
zfs: send receive(smart backups+snapshots) or some thing similar.

Re: [ovirt-users] Is this guide still valid?data-warehouse

2017-09-27 Thread Arman Khalatyan
Thank you for clarification,
So in the future you are going to push everything to kibana as a storage,
what about dashboards or some kind of reports views.
Are you going to provide some reports templates as before in dwh in 3.0.6
eg heatmaps etc..?

Re: [ovirt-users] Current state of infiniband support in ovirt?

2017-09-19 Thread Arman Khalatyan
Hi Jeff,
you can find some information in the docs:
https://www.ovirt.org/documentation/how-to/networking/infiniband/
The IB can be used for the storage and vm migration network,  but not for
the VM network due to the bonding.
in our institute we have such a setup, storage over IB the rest over 10G
network. Works over the several years quite stable.
Now I am testing the glusterfs over rdma, unfortunately there are some bugs
in the ovirt storage implementation, so the gluster does not benefit from
the  IB performance, but you can use them over tcp/ip stack.

this is due to the cluster cpu type, you should select the right

Re: [ovirt-users] After upgrading to 4.1.4 unable to start VM or migrate them

2017-08-02 Thread Arman Khalatyan
nothing special:
1) upgrade one of the nodes(overall we have 7) it became green

2) engine-setup (it runs on the separate node) db vacuum,etc answered with
yes.
went w/o errors.
3) i try to put into maintenance the next node, error came.
4)failure on migration but success on selecting of SPM.

i have another test system, will try to upgrade tomorrow.

Re: [ovirt-users] After upgrading to 4.1.4 unable to start VM or migrate them

2017-07-31 Thread Arman Khalatyan
Ok I found the ERROR:
After upgrade the schedule policy was "none", I dont know why it was moved
to none but to fix the problem I did following:
Edit Cluster->Scheduling Policy-> Select Policy: vm_evently_distributed
Now I can run/migrate the VMs.

I think there should be a some bug in the upgrade process.

Re: [ovirt-users] workflow suggestion for the creating and destroying the VMs?

2017-07-21 Thread Arman Khalatyan
thanks,the downscaling is important for me,
 i was testing something like:
 1) clone from actual vm(super slow,even if it is 20GB OS, needs more
investigation,nfs is bottle neck)
2) start it with dhcp,
3) somehow find the ip
4) sync parameters between running vm and new vm.

looks that everything might be possible with the python sdk...

are there some examples or tutorials with cloudinitscripts?

Yes, thanks for mentioning puppet, we have foreman for the bare metal
systems.
I was looking something like preboot hook script, to mount the /dev/sda and
copy some stuff there.
Is it possible to do that with cloud-init/sysprep?

Hi,
Can some one share an experience with dynamic creating and removing VMs
based on the load?
Currently I am just creating with the python SDK a clone of the apache
worker, are there way to copy some config files to the VM before starting
it ?

Re: [ovirt-users] The web portal gives: Bad Request: 400

2017-04-23 Thread Arman Khalatyan
Hi Yaniv,
I'm unfortunately there is nothing in the logs, it looks like a ovirt
doesnot listen to the right interface.
We have multiples interfaces internal and external access.
We sometimes ago we renamed the engine name to work with the external ip
address. Now it is listening only to the local address.
To fix it i just added:

/etc/ovirt-engine/engine.conf.d/99-setup-http-proxy.conf


One need to dig more to fix it

[ovirt-users] The web portal gives: Bad Request: 400

2017-04-20 Thread Arman Khalatyan
After the recent upgrade from ovirt Version 4.1.1.6-1.el7.centos. to
Version 4.1.1.8-1.el7.centos

The web portal gives following error:
Bad Request

Your browser sent a request that this server could not understand.

Additionally, a 400 Bad Request error was encountered while trying to use
an ErrorDocument to handle the request.


Are there any hints how to fix it?

BTW the rest API works as expected, engine-setup went without errors.

Thanks,

Re: [ovirt-users] Serious Trouble - Lost Domains

2017-03-14 Thread Arman Khalatyan
What kind of storage are you using?
If you check images with "qemu-img info" are you able to see the
filesystems?
Can you simply import the domain unto the new ovirt?

This was just GIU suggestion when I was creating the cluster it was asking
for the 3 Hosts , I did not knew even that an Arbiter does not keep the
data.
I am not so sure if I can change the type of the glusterfs to triplicated
one in the running system, probably I need to destroy whole cluster.

We  have also several huge systems running with zfs quite successful over

Yes I saw that glusterfs is CPU/RAM hugry!!! 99% of all 16 cores used just
for healing 500GB vm disks. It was taking almost infinity compare with nfs
storage (single disk+zfs ssd cache, for sure one get an penalty for the

No, I have one pool made of the one disk and ssd as a cache and log device.
I have 3 Glusterfs bricks- separate 3 hosts:Volume type Replicate
(Arbiter)= replica 2+1!
That how much you can push into compute nodes(they have only 3 disk slots).

Thank you all  for the nice hints.
Somehow  my host was not able to access the userspace RDMA, after
installing:
yum install -y libmlx4.x86_64

I can mount:
/usr/bin/mount  -t glusterfs  -o
backup-volfile-servers=10.10.10.44:10.10.10.42:10.10.10.41,transport=rdma

Looks the rdma and gluster are working except ovirt GUI:(

With  MountOptions:
backup-volfile-servers=10.10.10.44:10.10.10.42:10.10.10.41,transport=rdma

I am not able to activate storage.

Dear Deepak, thank you for the hints, which gluster are you using?
As you can see from my previous email that the RDMA connection tested with
qperf. It is working as expected. In my case the clients are servers as
well, they are hosts for the ovirt. Disabling selinux is nor recommended by
ovirt, but i will give a try.

I have been testing glusterfs over RDMA & below is the command I use.
Reading up the logs, it looks like your IB(InfiniBand) device is not being
initialized. I am not sure if u have an issue on the client IB or the
storage server IB. Also have you configured ur IB devices correctly. I am
using IPoIB.

Can you check your firewall, disable selinux, I think, you might have
checked it already ?

Re: [ovirt-users] Replicated Glusterfs on top of ZFS

2017-03-02 Thread Arman Khalatyan
no,
ZFS itself is not on top of lvm. only ssd was spitted by lvm for slog(10G)
and cache (the rest)
but in any-case the ssd does not help much on glusterfs/ovirt  load it has
almost 100% cache misses:( (terrible performance compare with nfs)

ok I forgot  that if you let vdsmd to manage libvirtd than everything is
lockdown to readonly you should try this:
1) saslpasswd2 -a libvirt username
2) then
 virsh list --all

[ovirt-users] Hot to force glusterfs to use RDMA?

2017-03-02 Thread Arman Khalatyan
Hi,
Are there way to force the connections over RDMA only?
If I check host mounts I cannot see rdma mount option:
 mount -l| grep gluster
10.10.10.44:/GluReplica on
/rhev/data-center/mnt/glusterSD/10.10.10.44:_GluReplica
type fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)

Re: [ovirt-users] Gluster setup disappears any chance to recover?

2017-03-02 Thread Arman Khalatyan
I just discovered in the logs several troubles:
1) the rdma support was not installed from glusterfs (but the RDMA check
box was selected)
2) somehow every second during the resync the connection was going down and
up...
3)Due to 2) the hosts are restarging daemon glusterfs several times, with
correct parameters and with no parameters.. they where giving conflict and
one other other was overtaking.
Maybe the fault was due to the onboot enabled glusterfs service.

I can try to destroy whole cluster and reinstall from scratch to see if we
can figure-out why the vol config files are disappears.

Re: [ovirt-users] Gluster setup disappears any chance to recover?

2017-03-01 Thread Arman Khalatyan
ok I will answer by my self:
yes gluster daemon is managed by vdms:)
and to recover lost config simply one should add "force" keyword
gluster volume create GluReplica replica 3 arbiter 1 transport TCP,RDMA
10.10.10.44:/zclei22/01/glu 10.10.10.42:/zclei21/01/glu
10.10.10.41:/zclei26/01/glu
force

now everything is up an running !
one annoying thing is epel dependency in the zfs and conflicting ovirt...
every time one need to enable and then disable epel.

Re: [ovirt-users] Gluster setup disappears any chance to recover?

2017-03-01 Thread Arman Khalatyan
ok Finally by single brick up and running so I can access to data.
Now the question is do we need to run glusterd daemon on startup? or it is
managed by vdsmd?

Re: [ovirt-users] Gluster setup disappears any chance to recover?

2017-03-01 Thread Arman Khalatyan
all folders /var/lib/glusterd/vols/ are empty
In the history of one of the servers I found the command how it was created:

gluster volume create GluReplica replica 3 arbiter 1 transport TCP,RDMA
10.10.10.44:/zclei22/01/glu 10.10.10.42:/zclei21/01/glu 10.10.10.41:
/zclei26/01/glu

But executing this command it claims that:
volume create: GluReplica: failed: /zclei22/01/glu is already part of a
volume

Any chance to force it?

[ovirt-users] Gluster setup disappears any chance to recover?

2017-03-01 Thread Arman Khalatyan
Hi,
I just tested power cut on the test system:

Cluster with 3-Hosts each host has 4TB localdisk with zfs on it
/zhost/01/glu folder as a brick.

Glusterfs was with replicated to 3 disks with arbiter. So far so good. Vm
was up an running with 5oGB OS disk: dd was showing 100-70MB/s performance
with the Vm disk.
I just simulated disaster powercut: with ipmi power-cycle all 3 hosts same
time.
the result is all hosts are green up and running but bricks are down.
in the processes I can see:
ps aux | grep gluster
root 16156  0.8  0.0 475360 16964 ?Ssl  08:47   0:00
/usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO

What happened with my volume setup??
Is it possible to recover it??
[root@clei21 ~]# gluster peer status
Number of Peers: 2

to use virsh you can set password:

 saslpasswd2 -a libvirt foo (foo is some username)

then use virsh with that username as usual

[ovirt-users] Troubles after resizing the iscsi storage.

2017-02-20 Thread Arman Khalatyan
Hi,
I just have 1TB iscsi  storage with virtual machine with  several disks.
After shutdown the vm I just detached storage and removed from the cluster
and ovirt totally.
1) Then on the target resized the exported volume to 13TB,
2) iscsiadm -m node -l on the host I resized
iscsiadm -m node -l
pvresize /dev/mapper/.
iscsiadm -m node -u

After importing back to the ovirt over the gui, I can see the vm is in the
import field but I cannot see separate disks
Importing failing in the stage "Executing".
are there way to fix it?
On the host with "lvs" I can see the disks are there.
thanks,
Arman.

Is that on the hosted engine? Or separate bare machine?
