Re: [ovirt-users] How to reset vm from unknown state?

[Arman Khalatyan]

Thank you for Ideas,
To clarify the situation:
I have a cluster with 2 hosts:C1 and C2.With stroage on ZFS(d1) and
XFS(d2) both are with nfs mounted.
d1 was away all and VMs where paused or unknown mode.
After recovery d1 one VM with CentOS 7 didnot come back it stay in
ovirt-engine gut always in unknown state(with icon ?).
I just tested to be sure the bare metal hosts are ok: Movind around
some VMs from c1-c2 and disks d1-d2 .
I just rebooted hosts using maintenance mode+reinstall, then reboot by IPMI.
seems to me database of ovirt did not recognize that this VMhost needs
to be in offline or down state.
Over the web-gui I am not able to delete or reboot the VM.
Can I somehow change VM state to down in the database? Is it normal practice?

Thanks,
Arman.

 It seems like it's not. Can you reboot it? (supposing it may be blocked on 
 storage access, or stale NFS handle if NFS, etc…)

Ok, The direct change in the database did the trick.

engine=# update vm_dynamic set status = 0 where vm_guid =(select
vm_guid from vm_static where vm_name = 'myvm');

after this I can start and stop from gui.
Thanks,

[ovirt-users] Is it possible to add ISCSI over iser?

[Arman Khalatyan]

Hi,
I am trying to attach my new storage domain over iser.
My server always gets that request is tcp/ip not rdma.
Simple work around is login from hosts over iser.
Would be good to add a possibility to select the protocol of
iscsi:tcp/iser/srp.

Thanks,
Arman

PS
for those who was struggling with same trouble:
1) on hosts:
add lines in /etc/rdma/rdma.conf
# Load iSER module
ISER_LOAD=YES
2) *service rdma restart (or modprobe ib_iser*
3)* iscsiadm -m discovery -t st -p 10.10.10.31 -I iser*
4) *iscsiadm -m node --login*

5) check if disks are there

  Arman,
 
  One of my storage domains is iSCSI using iSER.  You need the following
  in vdsm.conf:
 
  [irs]
  iscsi_default_ifaces = iser,default
 
  I believe the proper way to set that so it's preserved during node
  updates is the following
 
  # cat /etc/ovirt-host-deploy.conf.d/40-custom-vdsm-config.conf
  [environment:enforce]
  VDSM_CONFIG/irs/iscsi_default_ifaces=str:iser,default
 
  The filename I believe can be changed, just requires .conf extension
 
  Once VDSM is configured to use iser you can add the domain in the GUI
  using the IPoIB IP address to initiate iSER.
 
  ovirtnode01 # iscsiadm -m session
  iser: [3] 192.168.211.245:3260,1
 iqn.2014-04.DOMAIN.vmstore1:ovirt-data_iscsi

 Hi, well there is the release process, basically:

 every 6 months a new point release (3.5 now, 3.6 will be next)
 see: http://www.ovirt.org/Release_Process

 ovirt does support the last release before the actual
 release, but this rule somehow does already got broken:

 the current release is 3.4.4

 the next release will be 3.5 (RC4 just released)

 but even with 3.5 not released there will be no
 updates for 3.3.z (3.3.5 being the last release)
 and there will be _only_ security updates for 3.4.z.

 There is no planned 3.4.5 release if no security
 issues will be found.

 IMHO the process is somewhat broken here, because
 the support for 3.3.z is already abandoned with
 3.5 not being released yet (there where some delays
 in 3.5 release process, due to bugs).

 This might be due to the fast development cycle atm:

 3.2 was GA at 14.02.2013
 3.3 was GA at 12.09.2013
 3.4 was GA at 27.03.2014

 so as you can see 3.5. is already
 a bit delayed.

 you can find the 3.6 release plan (not yet feature complete)
 here:

[ovirt-users] How to fix wrong speed of the Infiniband Interfaces?

[Arman Khalatyan]

Hi,
I am using ovirt 3.4.4-1.
On the hosts I have 1Gbit(eth),10Gbit(eth) and 40Gbit(QDRInfiniband)
interfaces.
ib interface is used for the VM migration and iscsi disks.
If I go to the network interfaces I can see right speed for eth cards.
Unfortunately the IB interface speed is detected as 0b/s.
This causes very hi load information on vm migrate face. Which is not true.
IB can up to 2GB/s but already on 200MB/s load the hosts interfaces are
overloaded.
Where can I put the correct speed of IB interface?
Thanks,

  Hello,
 
  Last week I upgraded to 3.5 and on the engine side everything went
 absolutely fine. Now I'm wondering what to do about my hosts (full CentOS 6
  installs). Is the upgrade something the engine takes care of when I set
 the compatibility version to 3.5? Or should I install the ovirt-release35
 rpm
  and run yum update on all hosts?
 
  Should I expect impact on running VM's, eg. from restarting vdsm?


 Looks like we have a documentation gap here.
 I tried to search the oVirt site for pointing you to a section describing
 how to upgrade hosts but did not found one.

 I think that we need to finish
 http://www.ovirt.org/DraftInstallationGuide
 and probably prepare an upgrade guide too.

 You'll need to install the ovirt-release35 rpm on your hosts since the
 engine is not able to add the new repository (yet? maybe an RFE on this
 should
 be filled for easing the upgrade process of the hosts).

   The oVirt Project is pleased to announce the general availability
 of its sixth formal release, oVirt 3.5, as of October 17, 2014.
  
   oVirt is an open source alternative to VMware vSphere, and
 provides an excellent KVM management interface for multi-node
 virtualization. oVirt is
   available now for Fedora 19, Fedora 20, Red Hat Enterprise Linux
 6.5, and CentOS 6.5 (or similar) and allow you to use Red Hat Enterprise
 Linux
  7 and
   CentOS 7 too as node and for running Hosted Engine.
  
   New features include:
  
   Live Merge
   --
   If an image has one or more snapshots, oVirt 3.5's merge command
 will combine the data of one volume into another. Live merges can be
 performed
  with
   data is pulled from one snapshot into another snapshot. The
 engine can merge multiple disks at the same time and each merge can
 independently
  fail or
   succeed in each operation.
   Import Storage Domain
  
   This latest release expands oVirt's feature of importing ISOs and
 exporting storage domains to expand support for importing an existing data
  storage
   domain. Based on information stored in the storage domain, oVirt
 can revive entities such as disks, virtual machines, and templates in the
 setup of
   any data center to which the storage domain is attached.
  
  
   Advanced Foreman Integration
   
   oVirt 3.5 adds the capability to provision and add hypervisors to
 oVirt from bare metal. Foreman is a complete lifecycle management tool for
  physical
   and virtual servers. Through deep integration with configuration
 management, DHCP, DNS, TFTP, and PXE-based unattended installations, Foreman
  manages
   every stage of the lifecycle of your physical or virtual servers.
 Integrating Foreman with oVirt helps add hypervisor hosts managed by Foreman
  to the
   oVirt engine.
  
  
   Enhanced Authentication, Authorization and Accounting Support
   -
   A new architecture has been built for oVirt 3.5's authentication,
 authorization and accounting (AAA) system. The enhancements will provide a
 clear
   separation of authentication from authorization and provide a
 developer API to develop custom extensions for authentication and

   New PatternFly Interface

  Hello,
 
  Last week I upgraded to 3.5 and on the engine side everything went

 the compatibility version to 3.5? Or should I install the ovirt-release35

 Looks like we have a documentation gap here.
 I tried to search the oVirt site for pointing you to a section describing
 how to upgrade hosts but did not found one.

 I think that we need to finish
 http://www.ovirt.org/DraftInstallationGuide
 and probably prepare an upgrade guide too.

 You'll need to install the ovirt-release35 rpm on your hosts since the
 engine is not able to add the new repository (yet? maybe an RFE on this
 should
 be filled for easing the upgrade process of the hosts).

 will combine the data of one volume into another. Live merges can be
 performed
  with
   data is pulled from one snapshot into another snapshot. The
 engine can merge multiple disks at the same time and each merge can

   Import Storage Domain
  
   This latest release expands oVirt's feature of importing ISOs
 and exporting storage domains to expand support for importing an existing
 data
  storage
   domain. Based on information stored in the storage domain, oVirt
 can revive entities such as disks, virtual machines, and templates in the
 setup of
   any data center to which the storage domain is attached.
  
  
   Advanced Foreman Integration
   
   oVirt 3.5 adds the capability to provision and add hypervisors
 to oVirt from bare metal. Foreman is a complete lifecycle management tool
 for
  physical

 management, DHCP, DNS, TFTP, and PXE-based unattended installations, Foreman
  manages
   every stage of the lifecycle of your physical or virtual
 servers. Integrating Foreman with oVirt helps add hypervisor hosts managed
 by Foreman
  to the
   oVirt engine.
  
  
   Enhanced Authentication, Authorization and Accounting Support

the second one I am not so sure if it is an bug or a feature?
The numa menu is grayed if the VM is HA.
If one remove the HA and force set VM to run on single node without

[ovirt-users] Are there some general strategyhow to Iscsi strorage domain?

[Arman Khalatyan]

Hi,
I have 2x40TB domains each are exported with iser/iscsi with ib and 10Gb
interfaces.
For sure they are RAID6 storage little bit save on failure.
But I was wondered if any way to backup those domains. particularly master
one.

I was thinking somehow DRBD based replication, with lvm snapshots etc. But
it looks like overkill.
Will be nice somehow to deploy replicated/HA Master domain with ability to
backp on tapes as well.

Any ideas are welcome.

Thank you Trey for sharing your setup.
I have also one test system with zvol exported with iscsi over 10G.
Unfortunately the difference in performance of zfs over raid controller is
huge, particularly where VM running mysql. I did not try HBAs yet, I have
only LSI/Adaptec/Areca RaidControllers they dont have IT mode. Maybe that
can be the reason.
For sure always one need to find the sweet edge between performance and
reliability.
Just for comparison with yours I get on random IO:
zvol/16Disks/Raid2/tgtd/iscsi/10G- on VM multiple rsync - ~100-150MB/s,
Same HW but disks with Areca RAID6 -  650MB/s stable even more in some
cases.
The best performance I got on FDR iser-
80% of bare metal performance: 1500MB/s but ovirt goes mad claiming that
Network and Disk devices are saturated. My VM goes time by time to paused
state.
 It is due to that the Ovirt treating all ib devices as 10Gbit cards(in
terms of speed).:(

 ZFS is probably not an easy solution as requires rebuilding your storage,

Re: [ovirt-users] hosted engine on iSCSI deep dive

[Arman Khalatyan]

Thank you for a Nice presentation.
Could you please explain: You kill the HA ovirt-engine at 25:52. Which
process will bring it up again? Is it task of vdsm on the host?
thanks.
Arman.

Re: [ovirt-users] How to stick VM to hosts?

[Arman Khalatyan]

I just found very simple solution by adding a dummy interface on host.
Same with VMs. So the only hosts with dummy interface are able to run the
VMs. Works even with HA-VMs.
For sure it is  a hack and not so elegant solution, But it works.:)

 Just for the record, affinity deals with the relation

 We're considering extending affinity to handle hosts

 Hi Arman,
 Are you working with ovirt node or standard CentOS?

 Note that ovirt node is different as it's works like a live cd-
 it runs from memory. In order to save some configurations (such
 as networking) the local disk is used.

[ovirt-users] Unable to reinstall hosts after network removal.

[Arman Khalatyan]

Hello,
I have a little trouble with ovirt  3.5 on CentOS6.6:
I was removing all networks from all hosts.
Then after removing network from data center the hosts went to unusable.
Every time after reinstall the host claims that the network is not
configured, but it s already removed from network tab in DC.
Where from it gets the old configuration? the old interfaces also restored
every time on the reinstalled hosts.
Which DB table is in charge of dc-networks?

Thanks,
Arman.

Re: [ovirt-users] Unable to reinstall hosts after network removal.

[Arman Khalatyan]

My setup  has 3 networks: 1xIB,1x10Gbit+1Gbit for ovirt-management.
The ovirt network does not have any trouble, it is always there.
I was trying to rename or remove my IB network which was used for VM
migrations.
I was using web-GUI, which was removing IB0 network w/o problem. After
removal the hosts where ok. Then I put them to maintenance mode. To refresh
iptables rules I did reinstall. then reinstall was failing with message
that IB0 not attached to any interface. But IB0 interface is not possible
to attach it is already deleted and not visible in any network dialog.
After creating interface with the same name everything is online now.
My current interface list is following:
 virsh -r net-list
Name State  Autostart Persistent
--
;vdsmdummy;  active nono
vdsm-cls10G  active yes   yes
vdsm-IB0 active yes   yes
vdsm-ovirtmgmt   active yes   yes

On this host the IB0 is not atached to any interface, I wondered, if it
should show up  in the net list?

I think the GUI does not rename/remove the interface from the DB. Some
constrain keeps still IB0 in DB.

  Subject: [ovirt-users] Unable to reinstall hosts after network removal.
 
  Hello,
  I have a little trouble with ovirt 3.5 on CentOS6.6:
  I was removing all networks from all hosts.

 Did you use the setup networks dialog from the UI in order to remove those
 networks ?
 Or have you removed those networks from the host directly (where you
 should used the:
 1. virsh net-destroy 'the-network-name'
 2. virsh net-undefine 'the-network-name'
 )

 can you report the output of 'virsh -r net-list'  ?

  Then after removing network from data center the hosts went to unusable.

 What was the host's status prior to removing its networks ? Was it up ?

  Every time after reinstall the host claims that the network is not
  configured, but it s already removed from network tab in DC.

 What is the missing network name ? Is it 'ovirtmgmt' ?

  Where from it gets the old configuration? the old interfaces also
 restored
  every time on the reinstalled hosts.

 The hosts via vdsm reports their network configuration via the
 'getCapabilities' verb
 of vdsm. You can try running it on the host:

 vdsClient -s 0 getVdsCaps

 and examine the nics / neworks / bridges / vlans / bonds elements.

  Which DB table is in charge of dc-networks?
 

 The retrieved information from vdsm is reported to 'vds_interace' table.
 The dc networks are stored in 'networks' table and networks attached to
 clusters are stored in network_cluster table.

 I wouldn't recommend on deleting entries from the tables directly. There
 are
 certain constraints which shouldn't be violated, i.e. the management
 network
 'ovirtmgnt' is blocked for removal from the engine.

  Thanks,
  Arman.

Re: [ovirt-users] Unable to reinstall hosts after network removal.

[Arman Khalatyan]

Ok I found the conflict. The ip rule list  does not have any record on IB0
interface, all other networks are updated correctly but not IB one.
Probably this is not a good idea to have an ISCSI storage devices with the
same interface as VM network.
the network update operation trying to put interface up and down in that
point all iscsi devices going to IO/failure this stops to update IB
interface data.

Maybe one need to put whole cluster to maintenance mode in order to change
Storage dependent network setup?

this is the main trouble which prevents to fix/change any network setup on
IB0 interface.

  My setup  has 3 networks: 1xIB,1x10Gbit+1Gbit for ovirt-management.
  The ovirt network does not have any trouble, it is always there.
  I was trying to rename or remove my IB network which was used for VM
  migrations.
  I was using web-GUI, which was removing IB0 network w/o problem. After
  removal the hosts where ok.

 Have you checked the option of save network configuration in the setup
 networks
 dialog (iirc should have been checked by default) ?

 Could you also attach the /var/log/ovirt-engine/engine.log from the engine
 server
 and /var/log/vdsm/vdsm.log and /var/log/vdsm/supervdsm.log from the node so
 we can see which request was sent to vdsm and its result ?

  Then I put them to maintenance mode. To refresh
  iptables rules I did reinstall. then reinstall was failing with message
  that IB0 not attached to any interface. But IB0 interface is not possible
  to attach it is already deleted and not visible in any network dialog.
  After creating interface with the same name everything is online now.
  My current interface list is following:
   virsh -r net-list
  Name State  Autostart Persistent
  --
  ;vdsmdummy;  active nono
  vdsm-cls10G  active yes   yes
  vdsm-IB0 active yes   yes
  vdsm-ovirtmgmt   active yes   yes
 
  On this host the IB0 is not atached to any interface, I wondered, if it
  should show up  in the net list?
 
  I think the GUI does not rename/remove the interface from the DB. Some
  constrain keeps still IB0 in DB.

Subject: [ovirt-users] Unable to reinstall hosts after network
 removal.
   
Hello,
I have a little trouble with ovirt 3.5 on CentOS6.6:
I was removing all networks from all hosts.
  
   Did you use the setup networks dialog from the UI in order to remove
 those
   networks ?
   Or have you removed those networks from the host directly (where you
   should used the:
   1. virsh net-destroy 'the-network-name'
   2. virsh net-undefine 'the-network-name'
   )
  
   can you report the output of 'virsh -r net-list'  ?
  
Then after removing network from data center the hosts went to
 unusable.
  
   What was the host's status

[ovirt-users] ovirt-engine gone: how to restore iscsi storage?

[Arman Khalatyan]

My ovirt engine sever gone with 3.5.0,
Another host is already fresh installed with 3.5.1.
Is it possible to attache iscsi storage with old VMs?
I got iscsi storage (master) and another one with NFS.
I was testing with NFS DATA, it is importing but no any VMs/Disks are visible.
Are there some way to rescan VMs/disk on imported storage?
How to restore it?


Thanks,
Arman.

[ovirt-users] How to import existing DC with replicated glusterfs

[Arman Khalatyan]

Hi,
I try to import existing DC with replicated glusterfs in Ovirt 3.5.1
on centos 7.0.
Usually in the normal case I set the mount points in the fstab as:

server01:DATA   /data  glusterfs
defaults,_netdev,log-level=WARNING,backupvolfile-server=server02

In the import dialog the mount options are grayed.
If I put my server01:DATA everything works as far as server01 is there.
Can I set somewhere the fail-over ip adress for the next replica?
thanks,
Arman.

[ovirt-users] Why my Over Allocation Ratio is negative??

[Arman Khalatyan]

In my ovirt-GUI(Version 3.5.2-1.el6 prerelease) I can see following:

Size:
20479 GB
Available:
11180 GB
Used:
9299 GB
Allocated:

What does it mean??
My storage is iscsi with 20TB size.

[ovirt-users] Is ovirt on HA-iscsi???

[Arman Khalatyan]

I am trying to use HA-iscsi target as a ovirt storage.
The smooth fail-over is working nicely without ovirt setup.

my config is following:
HA-iscsi: hosta-drbd-hostB-floatingIP-iscsi(iet)
ovirtengine(host)
cloud01-iscsi storage from floatingIP
Expected failover:
reboot hostB, hostA takeover.

cloud01 should not feel any error.
What I see actually the VMs are in the paused state.


It will be nice if someone can provide a reference on how ovirt/vdsm
is acting on iscsi failure?

Thanks,
Arman.

Hi,
I can see many

I the top I can see that lvm process is using 100%.
My migration from iscsiA to iscsiB storage is terrible slow.
The lvm process always changing its pid.

Re: [ovirt-users] Migration from VirtualBox to oVirt (do's and don'ts)

I was able to move my vms from virtualbox running on win7 to ovirt.
The steps are following:
1)Export virtualbox vm to raw format.
2) upload it to export domain in ovirt
3) clone new vm from (2) setup hw as you need.
I didnot try for windows guests, but debian an rh guests are moved without

[ovirt-users] How to manually restore ovirt-engine from sql dump file?

[Arman Khalatyan]

Hello,
Due to the HW error we lost ovirt-engine db.
We have only recent dump files from
/var/lib/ovirt-engine/backups/
Is it possible to restore database using dump files?
BTW the VMs are still running without ovirt-engine.

Thanks,
Arman.

Re: [ovirt-users] Failed to create live snapshot

[Arman Khalatyan]

What kind of storage are you using??
I had similar trouble with iscsi storage.
The workaround was to delete some bad symlinks in /rvem/data-center
The following steps are used to fix missing devices on the hosts:
Host->maintenance
On host rm -rf /rvem/data-center
yum reinstall vdsm
It will generate folder structure in /rvem
Before this backup your data. Maybe you hit another bug.
Good luck,
Arman
Hello,

I'm getting the following error when I try to create a snapshot of one VM.
Snapshots of all other VMs work as expected. I'm using oVirt 3.5 on Centos
7.

>Failed to create live snapshot 'fsbu3' for VM 'Odoo'. VM restart is
recommended. Note that using the created snapshot might cause data
inconsistency.

I think this is the relevant part of vdsm.log, what strikes me as odd is
the line:
>Thread-1192052::ERROR::2015-11-23
17:18:20,532::vm::4355::vm.Vm::(snapshot)

The part "The base volume doesn't exist" seems interesting.

Also interesting is that it does create a snapshot, though I don't know if
that snapshot is missing data.

Yes for sure, as you can see the options in foreman: 28. [\u2713] Configure
foreman_compute_ovirt

[Arman Khalatyan]

Thank you for the hint. I will try next week.
Foreman looks quite complex:)

I would prefer simple Python script with 4 lines: add, install, setup
networks and activate.

[ovirt-users] Solution for the multiple incompatible GPUs

[Arman Khalatyan]

Hi,
I am looking for some solution with multiple GPUs(FX5600quadro and
TESLA2050)
The drivers are not compatible in the bare metal, Therefore I was trying to
use passthrough as described here:
http://www.ovirt.org/develop/release-management/features/engine/hostdev-passthrough/

After installing the nvidia driver on the guest everything looks nice.
After running 2 or 3 times nvidia-smi to see the GPU status, the device
disappear.
I just tested with both gpus, with different drivers from nvidia, same
situation.

My environment is host and guest-Centos7.2, ovirt 3.6.6 engine(but host has
3.6.7RC due to the fix in passthrough gui)

Are there successful stories with  GPU+Ovirt?
Thanks,
Arman.

Re: [ovirt-users] How to automate the ovirt host deployment?

[Arman Khalatyan]

Nice! Finally no sad face anymore:)
I am testing centos 7.2, with foreman 1.11

Testing  now with unattended installations on multiple vms. Works like a
charm:)
Later will try on baremetals.
I need to learn how to write templates.

The foreman-install --enable-ovirt-provisioning-plugin breaks the foreman
installation. I need to dig deeper:(

Don't know what distribution you're using but setting all up manually
showed me that Foreman needs to be at at least 11 for the plugin to work.
Otherwise it behaved in the same way for me; all fine and well until the
provision plugin was installed and then *sadface* :)

Get Foreman up to version 11 and you'll be fine, is my guess.

[ovirt-users] How to automate the ovirt host deployment?

[Arman Khalatyan]

Hi, I am looking some method to automate the host deployments in a cluster
environment.
Assuming we have 20 nodes with centos 7 eth0/eth1 configured. Is it
possible to automate installation with ovirt-sdk?
Are there some examples  ?

Thanks,
Arman.

Re: [ovirt-users] How to automate the ovirt host deployment?

[Arman Khalatyan]

After few days playing with ovirt+foreman I can now deploy bare metal with
foreman and attach it to ovirt.
Over all it works, but there are some points to mention to beginners like
me:

a) To make a auto discovery ,ovirt and deployment working together one
should enable in "foreman-installer -i" following modules:
1. [\u2713] Configure foreman
2. [\u2713] Configure foreman_cli
3. [\u2713] Configure foreman_proxy
4. [\u2713] Configure puppet
6. [\u2713] Configure foreman_plugin_bootdisk
10. [\u2713] Configure foreman_plugin_dhcp_browser
12. [\u2713] Configure foreman_plugin_discovery
21. [\u2713] Configure foreman_plugin_setup
23. [\u2713] Configure foreman_plugin_templates
28. [\u2713] Configure foreman_compute_ovirt
33. [\u2713] Configure foreman_proxy_plugin_discovery

b) next follow the documentation:
http://www.ovirt.org/develop/release-management/features/foreman/foremanintegration/

You should be able to see the hosts from ovirt interface.
I was not able to add an auto-discovered hosts to ovirt it always trows an
exception: Failed to add Host  (User: admin@internal). probably it
is a bug.

In order to add the hosts: first I provisioned the auto-discovered hosts
with foreman to centos7 then over the gui in . Important here to add into
installation template the path to ovirt repository:

yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm

If your provisioned host does not know the repository you cannot add the
foreman host from the ovirt gui.

Sorry for the previous empty email.

I was testing foreman plugins for ovirt deploy. They are some how broken.
The foreman-install --enable-ovirt-provisioning-plugin breaks the foreman
installation. I need to dig deeper:(

Re: [ovirt-users] Getting qcow images into oVirt

[Arman Khalatyan]

Hi,
You can import regular qcow2 images into ovirt with few steps:
1)check what kind of  image you have qemu-img -info vm4import.img
2) create an vm with exact disk image size as qemu-img -info shows.
3) run vm in paused mode(sometimes it is hard to find out the VM disk)
4) go to host where paused vm is running: find /rhev |grep "your vm uuid"
and get your vm image UUID
5) do not use dd, use better
qemu-img convert -p  -O raw $1  ${2} or
qemu-img convert -p  -O qcow2 $1  ${2}
with -p option you have a nice progress bar:)

Then poweroff the paused vm and start it.
Maybe someone has a better tools, but sometimes better to get an idea
behind the scene without any wodoo scripts.

Re: [ovirt-users] matching / mapping ovirt storage domain images to VMs

[Arman Khalatyan]

Hi,
If engine is down you can check directly on the hosts with virsh in
readonly mode.
virsh -r list
virsh -r dumpxml vmid
Then parse xml to get the disks.

Cheers,

[ovirt-users] Understanding direct lun connection: iscsi pass through disks

[Arman Khalatyan]

Hi, I am trying to combine performance and virtualisation with direct iscsi
disks .
Assuming we have vm with /dev/vda for OS two data disks from
iscsi01:/dev/sda and iscsi02:/dev/sdb direct lun disks configured over
ovirt interface.
The iscsi disks are used as zfs mirror inside the vm.
When one of the iscsi disks is not available then the whole host goes into
pause state.
Are there way to force ovirt do not freeze vm if direct lun is away?
Thanks,
Arman

Re: [ovirt-users] iSCSI Data Domain Down

[Arman Khalatyan]

Nice!
To automate that you can put it into:
/etc/rc.local
chmod +x /etc/rc.local
Then put dmremove and targetcli there.
Your service will come back after the power fails.

Re: [ovirt-users] Is it possible to disable qxl video?

[Arman Khalatyan]

I just testing several GPUs with pci-passthrough: GTX630, Tesla 2050 and
FX5800.
None of them I got running with opengl/direct rendering inside the virtual
machine.
I was thinking something to do with qxl driver, but after blacklisting it
in the VMs kernel nothing was changed.
The VMs Xorg claiming always no display found even if I configure it with
headless option: nvidia-xconfig -a --use-display-device=None
--virtual=1280x1024
But with nvidia-smi I can see the GPU status, and I can run all cuda tests
where opengl/X11 is not involved.
My test system is CentOS 7 with ovirt 4.
BTW If I clone VM which was not running, to real host on bare metal,
everything is running as expecting.

Re: [ovirt-users] Is it possible to disable qxl video?

[Arman Khalatyan]

Thanks for clarification. the kvm=off solved the problem.
NICE!!! I got now inside the VM:
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GT 630/PCIe/SSE2
OpenGL core profile version string: 4.4.0 NVIDIA 367.27
OpenGL core profile shading language version string: 4.40 NVIDIA via Cg
compiler
OpenGL core profile context flags: (none)

the steps to reproduce:
1) virsh edit render
2) change schema of xml: 
3) add following in the end before :



  
4)  start vm, install nvidia driver, check gpu: nvidia smi
5) install virtualgl, init 3
6) nvidia-xconfig --enable-all-gpus --separate-x-screens
--use-display-device=None --virtual=1280x1024
init 5
7) vglconnet render01.vm and finally: vglrun glxinfo or whatever!!!

Now back to origin: how to add this tweak in to ovirt?? :)

Yes I have a BusID inside the xorg.conf.
I just tested with virt-manager and indeed it is not a ovirt failure.
It is something to do with qemu-kvm + nvidia.
I found here:https://wiki.debian.org/VGAPassthrough  that nvidia disables
device when it is running on qemu-kvm is it still the case? to overcome
that one need to set:

-cpu host,kvm=off

in the command line of qemu.

I was trying to convert virsh commands to qemu native, but it fails on
Centos 7 :(
virsh dumpxml > render.xml
virsh  domxml-to-native qemu-argv render.xml
error: internal error: invalid PCI passthrough type 'default'

Hi,
I am also interested to upgrade my system from centos 7 ovirt 3.6.7 to

Re: [ovirt-users] Upgrade from 3.6 to 4.0

[Arman Khalatyan]

about a n hour ago I just tested to setup ovirt 3.6, then upgrade it, 2
nodes: host and ovirt on separated machines.
very smoothly upgraded, first engine upgrade then host upgrade.
The only trouble on hosts is that some pacages are still reffering to
ovirt-3.6 repository even ovirt-4.0 is there.
it is simple to fix: yum list installed| grep ovirt-3.6 then removing all
possible packages
next reinstall host from GUI.
Thats it.

[ovirt-users] How to benefit from pci-e ssd??

[Arman Khalatyan]

Hi, I wondered if there some setup where we can benefit from pci-e ssds?
One possible way is pci passthrough but then the vm does not migrate
anymore(am I right?).
Another way to share nvme over iscsi, but any software layer between vm and
nvme is dumping the performance(maybe worth to try iser or srp?)

Ps
I have seen that sime cloud providers are offering ssd vms, what does it
mean?:)

All upgrades are went smoothly! Thanks for the release.
There is an minor problem I saw:
After upgrading from 4.0.6 to 4.1 the GUI dialog for moving the disks from
one Storage to another is not rendered correctly when multiple disks(>8)
are selected for move.

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

[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.

Hi,
I just upgraded 4.0.6  to 4.1.
The 4.0 repository still there but after upgrade everything is ok except
the mom
The mom version in the 4.0 is higher than in 4.1 therefore it is not
upgraded from 4.1:

[ovirt-users] "epel-release preventing host update."

[Arman Khalatyan]

After upgrade to ovirt 4.1 the epel has an conflicts in the collectd part:
if you disable epel from the hosts it is ok.

the hosts are not able to check or update because of this:

Re: [ovirt-users] iscsi or iser targets are not detached from the host in the maintenance mode

[Arman Khalatyan]

The test disks are not attached to any virtual machine. nothing done on the
hosts.
 I just saw that the all test LUNs are still logged into target side so I
went to the host(it was in the maintenance ) all disks are still there.

I just managing everything over the web gui:
Select host as SPM, then disks->new->directLUN->discovertargets->login->ok
on the host the disks are visible.
iscsiadm -m session -o show
tcp: [6] 10.10.10.35:3260,1
iqn.2003-01.org.linux-iscsi.c1701.x8664:sn.5b791971cd78
(non-flash)

Putting host to maintenance:
the disks are still there:
lsscsi
[0:0:0:0]diskATA  ST3500630NS  K /dev/sda
[11:0:0:0]   diskLIO-ORG  c1701iser4.0   /dev/sdb
[11:0:0:1]   diskLIO-ORG  c1701iser32k 4.0   /dev/sdc

activating deactivating the host does not change situation.
I dont see any attempt of vdsm to logout the disks. I can see in the
vdsmd.logs that "[storage.Mount] unmounting /rhev/data-center/mnt/.."
unmounting the nfs part but nothing from [storage.ISCSI]

[ovirt-users] iscsi or iser targets are not detached from the host in the maintenance mode

[Arman Khalatyan]

Hi,
In ovirt 4.1 when I put the host into maintenance mode then the nfs mounts
are unmounted as expected.
but the hosts are still logged into the targets.

Is it expected behavior?? If yes what is  the use of it?
Another thing concerning to the permanently removed direct LUNs.
They are still in the /var/lib/iscsi/nodes and /var/lib/iscsi/send_targets/*
Would be good to cleanup the folders if users are removing permanently the
LUNs.

Thanks,
Arman.

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

[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)

I have glusterized 3 nodes:

GluReplica
Volume ID:
ee686dfe-203a-4caa-a691-26353460cc48
Volume Type:
Replicate (Arbiter)
Replica Count:
2 + 1
Number of Bricks:
3
Transport Types:
TCP, RDMA
Maximum no of snapshots:
256
Capacity:
3.51 TiB total, 190.56 GiB used, 3.33 TiB free
