[ovirt-users] Re: DataAccessResourceFailureException from one to to the next

[gregor]

THANK YOU, this solved my problem.

Solution:
ssh to engine
engine-setup --offline
...
no vaccum, because this will break the setup
...

now the engine is back online

[ovirt-users] DataAccessResourceFailureException from one to to the next

[gregor]

After one day I'm not able to login to the ovirt-engine webinterface
with the following error message:

"org.springframework.dao.DataAccessResourceFailureException: Error
retrieving database metadata; nested exception is
org.springframework.jdbc.support.MetaDataAccessException: Error while
extracting DatabaseMetaData; nested exception is
org.postgresql.util.PSQLException: This connection has been closed."

Things I tried which didn't help:
- engine: check if the database is up
- eninge: reboot
- hosts: reboot
- engine: xfs_repair

Any ideas?

[ovirt-users] Windows Server 2019 crash dxgkrnl.sys

[gregor]

Hello,

during the Installation of Windows Server 2019 after the first reboot
the VM crashed and inside the ntbtlog.txt I found that dxgkrnl.sys can
not be loaded.

Environment:
oVirt 4.3.6.7-1.el7
CPU: Intel-Westmere
Memory: 4096MB
Operation System VM config: Windows 2019 x64
HDD: VirtIO-SCSI
VirtIO driver: virtio-win-0.1.171_servers_amd64.vfd

Does anybody has an hint how to solve this problem and use Windows
Server 2019?

Besides: It's possible to install and use Windows Server 2019 in
VirtualBox 6.*. We have to install it in the meantime there to have a
alternative solution because it took now about two days to find a
solution. We tried different settings for VGA and drivers IDE ... and
many more.

best regards
gregor

[ovirt-users] Re: ovirt-ha-agent cpu usage

[gregor]

Hi,

did you found a solution or cause for this high CPU usage?
I have installed the self hosted engine on another server and there is
no VM running but ovirt-ha-agent uses heavily the CPU.

cheers

[ovirt-users] Can't boot VM: "At least one numa node has to be configured when enabling memory hotplug"

[gregor]

Hi,

yesterday I exported all my VM's and reinstalled the host fresh as
hosted-engine installation. After importing one VM and starting this, it
gaves me the error message (engine.log) see below.
After researching what "numa" means I don't have a clue what this should
mean or what was configured wrong. It's only one Server followed this
[1] instruction.

The Engine is up but the host stucks in NonResponsive.

The Webinterface stuck in "hanlding non respsonsive host". "Validating"
is green and "Executing" is spinning.

Can anybody help?
I found no errors in the logs under /var/log/ovirt-hosted-engine-ha and

[ovirt-users] Re: Upgrade 4.0 to 4.1: Global Maintenance Mode not recognized

[gregor]

I was able to change the maintenance state in the database to finish the
upgrade with engine-setup.

these are the lines:

select vds_id,ha_global_maintenance from vds_statistics where vds_id =
'706599d5-2dbc-400c-b9da-5b5906de6dbd';
update vds_statistics set ha_global_maintenance = 't' where vds_id =
'706599d5-2dbc-400c-b9da-5b5906de6dbd';

Now it's time to wait if the host and engine can reboot and start the vm's.

[ovirt-users] Upgrade 4.0 to 4.1: Global Maintenance Mode not recognized

[gregor]

Hello,

I upgraded one host from 4.0 to 4.1 without problems. Now I have a
problem with another host, in another network, where the Global
Maintenance mode is not recognized by engine-setup.

Is there a way to force the setup or set the maintenance mode inside the
database?

One problem can be that an the host was accidentally upgraded to 4.1
before I upgraded the engine.

kind regards

Re: [ovirt-users] Hosted Engine: Add another host

[gregor]

Hi,

finally these are my steps to add a host to my cluster:

- Install CentOS 7 minimal
- Configure NTP (otherwise the installer stopped with an error)
- Configure Network and DNS
- Add the oVirt repo: yum -y install
http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm
- Now add the host form the web management

Thanks for your help and links to the resources.

greetings

Today I had a similar problem. The time between the new host and the

[ovirt-users] Hosted Engine: Add another host

[gregor]

Hi,

I have a hosted-engine setup on one host. Today I try to add another
host from the UI but this gives me some errors without detail.

Is there a way to add a new host from the shell?
Not a node [1] because I plan to use docker as well on the host, it's a
test environment.
Or is it better to install the host as node?

[ovirt-users] Migrate oVirtBackup to sdk v4: How to create a snapshot

[gregor]

Hi,

I'm started the migration of my backup tool [1] from sdk v3 to v4.
Whats the correct REST URI to create a snapshost from a given VM and how
can this be done with the SnapshotsService.add(...) method?

This method needs a "snapshot" object, but currently I don't know how to
obtain one from a given VM or initialize one which works with the
SnapshotsService class.

A REST way will also be interesting because the Python SDK is horrible
documented and I plan to move to basic REST. Also the Python SDK has
lots of bug's which consumes many of the migration time. For example a
obtained VmService object get by the VmsService.list(with filter) method
has no information about the ID but iterating over all objects from
list() without filter result in usable VmService objects. This will
later be documented, meanwhile I wrote a workaround.

Re: [ovirt-users] Data Center jumping between online and non-responsive

[gregor]

On the host was no dns server set (/etc/resolv.conf). Is it save to edit the 
network parameter in /etc/sysconfig/network-scripts or is there another way and 
where can I check if the HostedEngine has the right dns server configured?

[ovirt-users] Data Center jumping between online and non-responsive

[gregor]

Hi,

I installed oVirt on another host machine and there the Data Center is jumping 
between 5-10 minuten from online to non-responsive.
It's nearly impossible to work with the webinterface because of the 
non-responsive state all action I like to start are blocked.
The installation is on a single host as hosted-engine

These lines fill the log:

[ovirt-users] Ping returns: Redirect Host(New nexthop ..

[gregor]

Hi,

sometimes a ping to a VM give "Redirect Host(New nexthop ...".
Lowering the MTU inside the VM gives better results but the network
throughput is very bad. (45kB/s during yum update)

Networkconfiguration:
Network name: WAN, MTU 1500 (default)
Network name: LAN, MTU 1500 (default)
LAN and WAN assigned to the host and ipv4 set to "none"
added WAN to eth0 to the VM
added LAN to eth1 to the VM

PING inside the LAN network works perfect.
PING to WAN gives sometimes a letency of 4000ms to 8.8.8.8
PING from WAN to the VM gives the problem described above and latency
sometimes up to 200ms and normally 0.7ms

When I set the MTU to 1400 inside the VM network configuration and also
on the VM itself the nexthop-problem are gone. A speedtest with
speedtest-cli[1] give me a speed of 0.35/3.45. The values differ extrem
from the values measured from a laptop inside the WAN network with the
same tool.

Can anybody give me a hint what the problen can be?

Re: [ovirt-users] Can't restart hosted-engine installation: vdsm did not start

[gregor]

Because the server has to be finished and shipped to my customer I
decided to reinstall the whole operating-system.
This is a very bad solution but after 20 hours of try-and-error I have
to find any solution.

Thanks for your help.

But when I run "hosted-engine --deploy" it stuck's during starting vdsm.

Re: [ovirt-users] ovirt-ha-agent cpu usage

Hi,

did you found a solution or cause for this high CPU usage?
I have installed the self hosted engine on another server and there is
no VM running but ovirt-ha-agent uses heavily the CPU.

[ovirt-users] Can't boot VM: "At least one numa node has to be configured when enabling memory hotplug"

[gregor]

Hi,

yesterday I exported all my VM's and reinstalled the host fresh as
hosted-engine installation. After importing one VM and starting this, it
gaves me the error message (engine.log) see below.
After researching what "numa" means I don't have a clue what this should
mean or what was configured wrong. It's only one Server followed this
[1] instruction.

[ovirt-users] Migrate to python-ovirt-engine-sdk4

[gregor]

Hi,

today I will migrate my backup tool [1] from oVirt version 3 to 4.
Is there anywhere a documentation to the new SDK? I downloaded the
source and read in the meantime through the code. It seems it will be a
lot of work :-(

[ovirt-users] ovirt-shell compatible with version 4?

[gregor]

Hi,

after upgrading to oVirt 4.* the ovirt-shell won't connect.

That's the installed version:
ovirt-engine-cli-3.6.2.0-1.el7.centos.noarch

Should this version work with the latest engine, this came from repo
ovirt-4.0 ?
Can't find ovirt-engine-cli-4.* in the repos.

Re: [ovirt-users] Can't start VM after shutdown

[gregor]

The VM has two disks both are VirtIO. During testing its now clear that
the problem occur only with two disks. When I select only one disk for
the snapshost it works.
Is this a problem of oVirt or is it not possible to use two disks on a
VM in oVirt?

Have you also two or more disks on your VM?

Here are the Testresults:
-
What does not work:
- Export the VM: Failed with error "ImageIsNotLegalChain and code 262"
- Clone the VM: Failed with error "IRSErrorException: Image is not a
legal chain" with the ID of the second Disk.

After removing the second Disk:
- Create offline snapshot: Works
- Remove offline snapshot: After two hours I run "engine-setup
--offline" to clean the looked snapshot !!!
- Export the VM: Works
- Import the exported VM: Works
- Add Disk to the imported VM: Works
- Create offline snapshot of the imported VM: Failed
- Clone the VM: Works
- Add Disk to the cloned VM: Works
- Create offline snapshot of the cloned VM: Failed

What works:
- Make offline snapshot only with the system disk: Works
- Remove offline snapshot of the system disk: Works
- Make online snapshot only with the system disk: Works
- Remove online snapshot of the system disk: Works

Hi,

I solved my problem, here are the steps but be carefully if you don't
know what the commands did and how to restore from backup don't follow this:

- ssh to the host
- systemctl stop ovirt-engine
- backup the database with "engine-backup"
- navigate to the image files
- backup the images: sudo -u vdsm rsync -av  
- check which one is the backing file: qemu-img info 
- check for damages: qemu-img check 
- qemu-img commit 
- rename the  + .lease and .meta so it can't be accessed

- vmname=srv03
- db=engine
- sudo -u postgres psql $db -c "SELECT b.disk_alias, s.description,
s.snapshot_id, i.creation_date, s.status, i.imagestatus, i.size,

FROM images as i JOIN snapshots AS s ON (i.vm_snapshot_id =
s.snapshot_id) LEFT JOIN vm_static AS v ON (s.vm_id = v.vm_guid) JOIN
base_disks AS b ON (i.image_group_id = b.disk_id) WHERE v.vm_name =

- note the image_guid and parent_id from the broken snapshot and the
active snapshot, the active state is the image_guuid with the parentid
----
- igid_active=
- igid_broken=
- the parentid of the image_guuid of the broken snapshot must be the
same as the activ snapshots image_guuid
- note the snapshot id
- sid_active=
- sid_broken=

- delete the broken snapshot
- sudo -u postgres psql $db -c "DELETE FROM snapshots AS s WHERE

change directory to "/root/Backups/oVirt"

- check for errors
- engine-setup --offline
- systemctl start ovirt-engine

Now you should have a clean state and a working VM ;-)

What was tested:
- Power up and down the VM

What does not work:
- Its not possible to make offline snapshots, online was not tested
because I will not getting into such trouble again. It took many hours
after the machine is up again.

PLEASE be aware and don't destroy your Host and VM !!!

Re: [ovirt-users] java.io.IOException: Command returned failure code 1 during SSH session

[gregor]

Hi,

The host are marked as up with two "Action Items":
- A new version is available.
- Power Management is not configured for this Host

The update information seems wrong, because lately I installed updates
with engine-setup and after this I updated yum like my other host. On
the other host there is only the "Power Management" note.

I can give you later more information's, currently the VM hast no
internet connection because there is a hanging VM which did not boot
(reported in another thread).

Re: [ovirt-users] Can't start VM after shutdown

Thanks for sharing the information's, I check the file structure and
database entries. I had problems with too long names during coding a
oVirt backup tool [1]. Here is a limitations list [2]. There was the
problem that a Windows VM name can only be 15 characters long, others
can named with 64 characters.

Which OS you used on the problematic VM?

Sound's bad. Recreating the VM is no way because this is a productive
VM. During testing I need to recreate it more than once. oVirt works

This is the message from engine.log

[ovirt-users] Documentation: Helper Utilities missing references

[gregor]

Hi,

I found the article to some "Helper Utilities" on the ovirt page [1] but
I can't find the mentioned helpers fkvalidaor.sh, taskcleaner.sh and
unlock_entity.sh.

Does anybody where these are? Especially I need the taskcleaner.sh
because a task is stuck since many days.

cheers

Re: [ovirt-users] 3.6 upgrade issue

[gregor]

Hi,

today I tried to upgrade from 3.6.4 to 3.6.5, as usual with
engine-setup. This time it gives me an schema update error and after
this the database is corrupt and gives me the same error you get.

Did you create a bug entry?
I'm tired of creating bugs for oVirt. Every time I touch oVirt I hit 1-5
bugs, it's so time consuming :-(

cheers
gregor

[ovirt-users] Fwd: Re: ***UNCHECKED*** Re: kvm vcpu0 unhandled rdmsr

[gregor]

Hi,

has anybody a last tip. Now the third installed Windows Server 2012 R2
VM is damaged and I will move tomorrow my host back to VMWare and leave
oVirt.

Re: [ovirt-users] kvm vcpu0 unhandled rdmsr

[gregor]

Update: The problem occur when a VM reboots.
When I change the CPU Type from default "Intel Haswell-noTSX" to
"Westmere" the error is gone.

But which CPU type is now the best so I don't lose performance.

Host CPU: Intel(R) Xeon(R) CPU E5-2603 v3 @ 1.60GHz

[ovirt-users] kvm vcpu0 unhandled rdmsr

[gregor]

Hi,

on one Host I get very often the message

"kvm ... vcpu0 unhandled rdmsr ..."

When this occurs some VM's are stuck. Really bad is this for an Windows
Server 2012 R2 VM which stucks so heavy that the VM is getting corrupt
and the VM is unable to boot anymore and a Windows Recovery in any way
didn't help. Therefor I had to reinstall the VM, this works for some
day's but now the VM is still damaged. So I can't use Windows Server
2012 R2 on this machine but the customer needs it and I have some days
to ship it to my customer. So I have to decide to stay on oVirt or use
another product. Besides, oVirt run on my others hosts (without Windows
VM) very well since a long time.
On a CentOS 7 VM I have similar problems where the NIC is getting
offline sometime + the XFS filesystems get some errors and I have to fix
this in recovery mode.

oVirt: 3.6.4.1-1.el7.centos
machine: HP ProLiant ML110 Gen9
VM's: 3 CentOS 7 and one Windows Server 2012 R2

I hope somebody can help.

Re: [ovirt-users] virt-viewer shows no bootoption

[gregor]

Hi,

did you find a solution?
I have here a similar problem, the boot menu isn't shown because the VM
boots to fast or the console connection fire up to slow to I step into
the screen after the boot menu appears.

Is it possible to add a delay to the boot menu? (10 seconds, ...)

I have a broken Windows VM where I try the last 30 minutes to boot from
the DVD but the console connections connects so slow that it is always
in the boot phase and skips to boot from the Windows iso. It boots also
from the harddisk but it it is not set in the boot options.

Re: [ovirt-users] Cannot delete snapshot or export VM after adding disk

[gregor]

I hope not. Now I realized that this is a serious problem on other VM's
where it isn't possible anymore to delete snapshots, create snapshots.
These affects 3 very important VM's which costs a lot of work-hours :-(

[ovirt-users] Cannot delete snapshot or export VM after adding disk

[gregor]

Hi,

after the following workflow I can't remove or create a snapshot neither
export the VM.

- Create a VM
- Add a disk with 1GB
- Make a snapshot
- Add another disk with 1GB
- Export the VM

Now you I get the following error in the events list:

VDSM host01 command failed: Error during destination image manipulation


Did I understand something wrong or is there a bug?

Besides: The web-interface is extremely slow and copy&paste the error
messages are painful.

Re: [ovirt-users] Windows Server 2012R3 guest: BSOD

[gregor]

Hi,

I installed oVirt 3.6 with the host CPU "Intel(R) Xeon(R) CPU E5-2603 v3
@ 1.60GHz".

Installation and running of Windows Server Essentials 2012 R2 is possible.

These settings have to change to use the VM.
- Disk: Interface IDE
- Network: Type e1000

Here I have no problem with the CPU type, the cluster is set by default
to "Intel Haswell-noTSX Family".

Re: [ovirt-users] Windows Server 2012R3 guest: BSOD

Hi,

I will install in the next few days a new host where Windows Server 2012
R2 should run. On my test machine I had run qemu with the cpu "Westmere"
to use Window Server 2012 R2, all other CPU's will bring a BSOD, reboot
loop or other issues.

Maybe this will help.

Re: [ovirt-users] HP ProLiant ML10 v2 or ML110 Gen9 with Windows Server Essentials 2012 R2 guest

[gregor]

The price is nearly double ML10 v2 about 900€ and ML110 Gen9 about 1800€
but the ML10 has only 2 cores and the ML110 6 cores.

Thanks for the hints I will compare different vendors too.

The use case is very simple:
- 6 clients
- 1 windows server to manage the clients
- 1 linux server for nagios, controller for wifi and other stuff
- 1 linux server for the firewall

[ovirt-users] HP ProLiant ML10 v2 or ML110 Gen9 with Windows Server Essentials 2012 R2 guest

[gregor]

Hi,

I planned for a new customer to use oVirt instead of competitor
virtualization.

Here are the environment:

Server choices:
1. HP ProLiant ML10 v2: 1x Dual Core 3,1GHz with 12GB RAM
2. HP ProLiant ML110 Gen9: 1x Xeon 1,6GHz with 12GB RAM

Harddisk:
- Raid1 on two SATA 2TB drives

Guests:
- 1x Windows Server Essentials 2012 R2
- 2x CentOS 7

Clients:
- 6 Windows Clients

Will the ML10 v2 server serve the needed performance? Because its a way
cheaper than the ML110. And will Windows Server 2012 run in oVirt,
because on my test machine (HP ProLiant ML350 G5) it didn't (maybe the
CPU is to old).

[ovirt-users] VM CPU stuck after upgrade to 3.6

[gregor]

Hi,

I recently upgraded from 3.5 to 3.6. The way I did is maybe for others
complicated but it worked: Export the VM's, remove 3.5, install 3.6
fresh and import the VM's. The normal upgrade way did not work in my
case and after many tries I did it the described way.

Now I have sometimes the problem that my Centos VM's throw a kernel
error like this:

--
kernel:BUG: soft lockup - CPU#0 stuck for 22s! [python:730]
--

Whats wrong here? I see no resource-problem the host usage is: memory
85%, CPU 62%

[ovirt-users] Which browser should I use?

[gregor]

Hi,

after a painful upgrade from 3.5 to 3.6 (AIO) I try to figure out the deeper 
meaning of the message which is display on the webinterface.

"This Browser version isn't optimal for displaying the application graphics 
(refer to Documentation for details)"

Can anybody please point me where in the Documentation this is explained?

I tried the latest Firefox and Google-Chrome from arch linux but still get 
these message? (I hope it doesn't mean to use the Internet Explorer or now 
known as Edge)

Re: [ovirt-users] Python: Clone snapshot into VM

[gregor]

Hi,

this was also an idea but with the single backup script you have the
advantage of backing up more than one VM at a time to speed up the
overall backup time and therefore to backup to different clusters and
different export domains.

But I will change the tool to set a list of VM's in the configuration to
cover both ways.

greetings
gregor

Hi, no this was not my intention. I was searching what is currently
available and possible. After this I wrote a little

Re: [ovirt-users] VLAN with one NIC

Thanks for the information's. I attached a second NIC to solve this,
then it was easy to configure ovirt to use the tagged and untagged network.

[ovirt-users] Python: Clone snapshot into VM

[gregor]

Hi,

I write currently a little backup tool in Python which use the following
workflow:
- create a snapshot -> works
- clone snapshot into VM -> help needed
- delete the snapshot -> works
- export VM to NFS share -> works
- delete cloned VM -> TODO

Is it possible to clone a snapshot into a VM like from the web-interface?

The above workflow is a little bit resource expensive but it will when
it is finished make Online-Full-backups of VM's.

Re: [ovirt-users] VLAN with one NIC

[gregor]

Thanks, now I can use the eth0 to connect to the web-interface and the
logical vlan network to use in a VM but I can't use the untagged VLAN1
in the VM. When I add a new logical network without VLAN tagging the
web-interface returns "Cannot have more than one non-VLAN network on one
interface."

When I create a logical network with taggged ID 1 I can't connect from a
VM to my VLAN1.

So I have to find a way to created the following networks:
- ovirtmgmt: without tagged vlan for managing -> works
- vlan1: without tagged vlan for the VM's to connect to my default
network -> currently no solution
- vlan10: tagged vlan with id 10 -> works

cheers

[ovirt-users] VLAN with one NIC

[gregor]

Hi,

is it possible to use different VLAN with one NIC in ovirt?

I can not add a logical network configured as VLAN to my ovirtmgmt
interface, I get "Cannot have a non-VLAN VM network and VLAN-tagged
networks on one interface."

The setup for the Port is a trunk of different tagged VLAN's and the
default VLAN1 is untagged. Normally this work under centos where I give
the nic eth0 an IP and create a nic eth0.10 for the VLAN with ID 10 and
set an IP for it.

[ovirt-users] Daily online VM backups

[gregor]

Hi,

what is the best way to make daily backups of my VM's without shutting
them down?

I found the Backup-Restore API and other stuff but no running
tool/script which I can use. I plan to integrate it into backuppc. Or is
there any "Best practice guide for backup"? ;-)

In the meantime I integrated engine-backup into backuppc as a pre-script.

Re: [ovirt-users] New storage domain on nfs share

[gregor]

No, but only in the allinone installation. When I install only the
engine, where I have to create a the cluster by my self, I can create a
NFS Data.
Another solution/workaround is to mount the NFS share in the underlying
operating system and use this "local" folder.

[ovirt-users] New storage domain on nfs share

[gregor]

Hi,

what is the right way to create a storage on an NFS share to use as data
storage for virtual machines?

It is only possible to create a storage "ISO/NFS" or "Export/NFS" where
I can not create disks for a virtual machine.

[ovirt-users] Problem with setup local storage

I try a testsetup on a CentOS 6.6.
I want to setup all on a single host so far.

When I try to create a local storage on the host i got always the

I trie the video howto in combination with the Quick Start Guide and
http://www.ovirt.org/Feature/AllInOne

I understand, that I've to generate a answer-file in cause of a bug for VDSM?
