[ovirt-users] Problems after upgrade to 3.5

[Alexandr Krivulya]

Hello!
Recently I have upgraded my installation to 3.5. Everything works fine
except of two things:

1. I cannot use REST API any more - "Internal server error 500" with
java exception. May be I missing something?
2. Cannot import VM from Export domain to Local Storage - "VM already
exists" error, but there are no any vms or disks on local storage.

No luck, same error. I think it's due to some misconfiguration...

Thank you, Alexander and Martin
It's "java.lang.RuntimeException: Unable to instantiate
MessageBodyWriter". This points me to a similar thread [1], which helps
to solve the problem.

Hello!
Now when virtio_console(4) driver available in CURRENT does anyone works
on porting ovirt-guest-agent to FreeBSD?

Yes, you are absolutely right. We moved all our infrastructure from pure
KVM (VM disks inside LVM) to oVirt in this way, except of FreeBSD VM's
that we moved via zfs send/recv.

[ovirt-users] VM migration timeout

[Alexandr Krivulya]

Hi!
How can I adjust migration timeout? I see this error in my vdsm.log when
I try to migrate one of my VM's:

The migration took 130 seconds which is exceeding the configured maximum
time for migrations of 128 seconds. The migration will be aborted.

Re: [ovirt-users] Backup

I think you could start from:
- http://www.ovirt.org/Features/Backup-Restore_API_Integration
- http://www.ovirt.org/Features/Backup_API
- http://www.ovirt.org/Ovirt-engine-backup

In our production environment we use storage filesystem snapshots with
subsequent archiving (NFS over ZFS), but it can't be useful in some tasks.

[Alexandr Krivulya]

Ок, I understand it. But in admin portal on hosts detail tab I see for
example 32 logical cores vs 16 in reports because of Hyper-Threading
enabled. All VM's on this host consumes 26 vCores. Does it
overallocation? According to report - yes, but actually I think not.

Can you clarify?

I have successfully build and run guest agent on FreeBSD-Current. It
provides a few information (for example fqdn and logged users) into
admin portal, but all other requires rewriting GuestAgentLinux2.py or
implementing it as separate module. I have no experience in python and
programming itself, but implementing some simple features may be quiet
easy. Can anyone help with it?

There is an old platform - no support for device passthrough. See my

When VM did not start after upgrade I did many different steps including
attaching/detaching usb devices via UI. All my attempts ended with the
same error. Only editing vm_device table by hand solves my problem.

I don't think you need care about it, because its real value calculates
via internal algorithms. Generally it depends on your workload. if you
have VM's that do a lot of random writes try to set recsize to equal or
greater value of guest file system block size.

Did you read this white paper? It might help you.

Re: [ovirt-users] oVirt 4.2: hostdev passthrough not working any more

[Alexandr Krivulya]

Hello, the same problem after upgrade to 4.2.1 :(


18.01.2018 11:53, Daniel Helgenberger пишет:

Hello,

yesterday I upgraded to 4.2.0 from 4.1.8.

Now I notice I cannot assign host dev pass though any more; in the GUI
the 'Pinnded to host' list is empty; I cannot select any host for pass
through host pinning.

When I was creating the particular VM in 4.1 it was working as expected.

The hostdev from before the upgrades are still present. I tried to
remove them and got an NPE (see below).

As a workaround, is the old hostusb[1] method I know back from 3.x still 
working in the 4.x
line?

AFAICT IOMMU is working

Does the host that previously worked report device passthrough

(and similarly named field in vdsm-client getCapabilities call) 

Now "Device Passthrough: Disabled", but usb passthrough works well on 4.1

I don't know about 4.2, but in 4.1 and 4.0 there is a right-click
context menu that gives you access to the Power Off feature.  If that
doesn't work (ISTR disucssion about removing that context menu), then
there must be a different way to access it now.



In 4.2 User portal was replaced with new VM portal. There is no 
right-click context menu on VM list :(

From admin portal I can poweroff VM.
