[ovirt-users] VM Serial Port connection to network port

2017-10-10 Thread Gagandeep Arora 
Hi,

Is it possible to configure a VM with a serial port connecting to network
port in client mode? Can someone point me in the right direction on how to
do this in ovirt.  We are running ovirt-4.0.6.3-1.1.

Regards,
Gagan

[ovirt-users] Help with SSL

2017-10-10 Thread ~Stack~ 
Greetings,

OS: Scientific Linux 7.3
Ovirt: 4.1.6.2-1.el7.centos
Foreman: 1.16.0-RC1

I updated my OVirt SSL cert from a self-signed to a purchased one using
the directions here:
https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/

Everything seems to work from the web interface.

Then I tried to add in Foreman. Thats where I get the error:

Unable to save
ERF56-1309 [Foreman::FingerprintException]: The remote system presented
a public key signed by an unidentified certificate authority. If you are
sure the remote system is authentic, go to the compute resource edit
page, press the 'Test Connection' or 'Load Datacenters' button and submit.

Everything I can find says that it *should* be resolved - From Red Hat,
to Foreman, to even the Ovirt list! Yet there it is!

Well after poking at it for a while, I realized that the cert Foreman
was auto-resolving was still the /OLD/ cert!

Step #2 in those ovirt directions says to break the symbolic link to
/etc/pki/ovirt-engine/ca.pem. But it doesn't say what to do with that
file. So I replaced it with my cert. Restarted ovirt and now Foreman
resolves the correct X509 cert! (I have no idea if that broke something
else.)

But I still get the error in foreman. :-(

I feel like I'm still missing something in the ovirt configs. Something
needs to be updated/replaced in ovirt that isn't in those docs.

Can anyone help me out please? I've been trying for hours and not making
progress.
Thanks!

~Stack~

Hi,

most probably you are affected by [1], so could you please check
certificates on all your AD servers?
You can verify using following command:

  ovirt-engine-extensions-tool --log-level=FINEST aaa login-user
--user-name= --profile=


Thanks

Supposing you're using all the right parameters in ldapsearch command,
it seems that the user you were looking up is not a valid user in that
directory server.

Please check with someone that can access to AD and verify the status
of the user with ADSI Edit.

It's an AD?

Can you check if userPrincipalName of the user you're trying to use
for connecting contains the login name in the format of
u...@domain.fqdn?

I had issues with users that had userPrincipalName wrongly formatted.
You should find nicola.gent...@polito.it on that field.

You can check in this way:

ldapsearch -h domaincontroller.dom.it -b "dc=dom,dc=it" -D u...@dom.it
-W -x sAMAccountName=user_to_search userPrincipalName | grep
userPrincipalName

Hello Nicola,

i don't see anything strange in your setup. Can you check if DN in files

 /etc/ovirt-engine/aaa/polito.it*.properties

are written correctly?

Can you also check with a ldapsearch if there is something strange in
your LDAP entry? I found that some users were not logging in correctly
due to wrong fields in the ldap object.

Hi,
I have a problem. Suddenly from the user portal the users of AD not

Re: [ovirt-users] Maximum storage per VM?

2017-10-10 Thread Dmitri Chebotarov 
Good Morning

I'm using virtio-scsi (also tried virtio), not using IDE (doesn't IDE have 4 
devices limit? it's long time since I used IDE...).

This is for servers hosting own/nextCloud and Samba for a small/medium groups 
with large datasets (60-80TB) per server.

If ovirt-scsi allows to attach >20 disks  then it meets my needs in this case. 
Thank you.

The reason I opted for LVM is performance. It's so much faster with LVM and 
striped volumes compared to a single large disk. I'm seeing very high 'iowait' 
numbers (to the point when VM is unresponsive) when I'm dumping large amount of 
data to a single disk. But with LVM striped volumes 'iowait' at around ~20% and 
I can get to ~750MB/s in the same environment (same config with single disk is 
~160MB/s).

Also, healing a single large disk on gluster takes ages (I'm using erasure 
coded volumes) .


Thank you,

Hello

I'm trying to find any info on how much storage I can attach to a VM.

Is there a recommended/maximum for number of disks and maximum disk size?

Disk count depends on the interface - IDE - very few, virtio- 20-something 
(depends on the number of PCI slots available), virtio-SCSI - more.
What is the use case?


I'm using GlusterFS as backend storage for the cluster.

The VM uses LVM (/w striped volumes) to manage attached disks.

Aren't you having layers over layers over layers? Is that the optimal 
arrangement?
(Again, would be interesting to understand the use case to better provide 
information).

Yes, when removing from physical servers I took that link as reference and
my steps reproduce them in practice.
I have not understood what do you mean with

"

"

Do yo mean this sequence:
1) flush the single path devices
2) remove the multipath device with multipath -f
??
O another thing?

Also I found in the mean time this bugzilla (for RHEV)
https://bugzilla.redhat.com/show_bug.cgi?id=1310330
where you replied and have work in progress... thanks!

I also found a reference (I miss the bugzilla id right now), that if you
have vdsm > of a certain version there are "no problems" on hosts in case
some unused (from oVirt point of view) LUNs are removed from storage array
while the hosts still enumerating them in their multipath listing. So that
this can lower potential problems...
I don't now if the enhancement s related to some sort of blacklisting or
what has been done at vdsm level

thanks, you're probably right. i was asking

(c) because the multipathing adds an additional level of abstraction in

Some questions:
- do the remove SD from gui imply vgchange -an of the VG and vgremove of
the vg?
Or are they delegated to post actions?

- do it imply the pvremove on the LUN?

After clearing what above I would imagine remaining steps would be, based
on my previous similar experience with iSCSI removal on physical servers:

- take note of the paths sdY, ... of mpathX

- remove the multipath device with
multipath -f mpathX

- flush the single paths devices
blockdev --flushbufs sdY for every path of the previous taken note ones

- remove single path devices
echo 1 > /sys/block/sdY/device/delete

- remove LUN from storage array
when previous steps done on all the hypervisors

Any comment?
Any further step at vdsm level files..?

Thanks in advance,

suddenly the two OS disks (for RAID 1) are not configured as multipath

A bit of a hassle, maybe put a notice to use Centos 7.3 in the upgrade

[ovirt-users] problem installing/upgrading hosts after 3.6 to 4.0 update

2017-10-10 Thread Jorick Astrego 
Hi,

It was time to upgrade our ancient ovirt 3.6 to 4.0 (and then to 4.1), 
but I'm having some issues in our test environment.

After upgrading the engine, I try to reinstall a fresh provisioned 
Centos 7.4 node but it fails on the vdsm service.

When debugging I see in the log that the step "vdsm-tool configure" fails:

Disk count depends on the interface - IDE - very few, virtio- 20-something
(depends on the number of PCI slots available), virtio-SCSI - more.
What is the use case?

Aren't you having layers over layers over layers? Is that the optimal
arrangement?
(Again, would be interesting to understand the use case to better provide
information).

Re: [ovirt-users] Ovirt 4.2 Fencing problems

2017-10-10 Thread Martin Perina 
Hi,

according to error and source codes you are using either oVirt 4.2 Alpha or
some nightly build, right? The error has already been fixed, so you need to
wait for oVirt 4.2 Beta or upgrade to some recent nighlty build.

Anyway please be aware that we cannot yet recommend using 4.2 Alpha/nightly
in production, so use at your won risk.

Regards

Martin
