[ovirt-users] Slow ova export performance
Hi All, I'm facing a really slow export ov vms hosted on a single node cluster, in a local storage. The Vm disk is 600 GB and the effective usage is around 300 GB. I estimated that the following process would take up about 15 hours to end: vdsm 25338 25332 99 04:14 pts/007:40:09 qemu-img measure -O qcow2 /rhev/data-center/mnt/_data/6775c41c-7d67-451b-8beb-4fd086eade2e/images/a084fa36-0f93-45c2-a323-ea9ca2d16677/55b3eac5-05b2-4bae-be50-37cde7050697 A strace -p of the pid shows a slow progression to reach the effective size. lseek(11, 3056795648, SEEK_DATA)= 3056795648 lseek(11, 3056795648, SEEK_HOLE)= 13407092736 lseek(14, 128637468672, SEEK_DATA) = 128637468672 lseek(14, 128637468672, SEEK_HOLE) = 317708828672 lseek(14, 128646250496, SEEK_DATA) = 128646250496 lseek(14, 128646250496, SEEK_HOLE) = 317708828672 lseek(14, 128637730816, SEEK_DATA) = 128637730816 lseek(14, 128637730816, SEEK_HOLE) = 317708828672 lseek(14, 128646774784, SEEK_DATA) = 128646774784 lseek(14, 128646774784, SEEK_HOLE) = 317708828672 lseek(14, 128646709248, SEEK_DATA) = 128646709248 The process take a single full core, but i don't think this is the problem. The I/O is almost nothing. Any idea/suggestion?

[ovirt-users] Fail install SHE ovirt-engine from backupfile (4.3 -> 4.4)
Hi Everyone,
In a test environment I'm trying to deploy a single node self hosted engine 4.4
on CentOS 8 from a 4.3 backup. The actual setup is:
- node1 with CentOS7, oVirt 4.3 with a working SH engine. The data domain is a
local NFS;
- node2 with CentOS8, where we are triyng to deploy the engine starting from
the node1 engine backup
- host1, with CentOS78, running a couple of VMs (4.3)
I'm following the guide:
https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to_4-4_4-3_SHE
Everything seems working fine, the engine on the node1 is in maintenance:global
mode and the ovirt-engine service i stopped. The deploy on the node2 stucks in
the following error:

[ovirt-users] Re: Fail install SHE ovirt-engine from backupfile (4.3 -> 4.4)
Ok, solved.
Simply the server node2 could not mount via NFS the data domain of the
node 1. Added node1 in the node2 firewall and in /etc/exports, tested
and everything went fine.

Francesco

[ovirt-users] Re: Can't find storage server connection
I try execute the script on different host passing different data storage:
- let's say that on host foo-host1, executing the script querying for
its own data storage named foo-data1 works correctly;
- and let's say that on host foo-host2, the same script querying for its
own data storage foo-data2 return the mentioned error;
If I execute the script on foo-host2 querying the foo-data1 domain data,
I got the error. If I execute on foo-host1 querying foo-data2, I still
got the error.
The ui.log engine when I try to manage the storage reports the following
error:

[ovirt-users] Random Crash
Hi all, I'm experiencing random reboot on several oVirt nodes (CentOS 7/8, oVirt 4.3/4.4 as well). Sometimes it happens three times in a day, and the more hosts I'm adding to my pool, the more I noticing. The logs are not helpful: it's like a brute poweroff cause there are no entries at all in the messages, vdsm, secure (I looked all over the logs) from the last "normal" entry (user logged in/off, normal vdsm log ecc.) until the first entry of the boot. kdump is enabled and /var/crash is empty. I used to run Xen on the servers of the same provider and I didn't have all of these frequent reboots, that's why I'm not sure it is a hardware related issue. Any advice on what enables for getting more info about this crash?

[ovirt-users] Re: Random Crash
Hi Strahil,
I have the Power Management setting disabled on all the hosts, so I
doubt it's a fencing issue related, but thank you for the suggestion.
The only logs that I see in the engine is the "set non responsive status".

My first guess would be fencing.
Fencing kicks in when there are network issues or when the Hypervisor
is stuck.
Check the engine's logs to verify that guess.

[ovirt-users] Importing VM from Xen Server 7.1
Hi all,
resuming the "dead" thread "Importing VM from Xen Server 6.5"
(https://lists.ovirt.org/pipermail/users/2016-August/075213.html) I'm trying to
import via GUI a VM from Xen Server 7.1 in a host Centos 8.4, oVirt 4.4.
Created the SSH key for vdsm user, added the IP in the host target firewall, an
ssh connection works, installed netcat on the target host, but like the
original thread, when i execute the "load" command for getting the VMS list, I
get the following error in the host and in the engine:

[ovirt-users] Missing snapshot in the engine
Hi,
I have an issue with a VM (Windows Server 2016), running on Centos8, oVirt host
4.4.8, oVirt engine 4.4.5. I used to perform regular snapshot (deleting the
previous one) on this VM but starting from 25/10 the task fail with the errors
that I'll attach at the bottom. The volume ID mentioned in the error... :
[...] vdsm.storage.exception.prepareIllegalVolumeError: Cannot prepare illegal
volume: ('5cb3fe58-3e01-4d32-bc7c-5907a4f858a8',) [...]
... refers to a snapshot's volume, because the ID of the current volume is
different and smaller that one in the engine UI with ID
5aad30c7-96f0-433d-95c8-2317e5f80045:

It seems that the last working snapshot performend on 25/10 was not completely
deleted and now is used as the base from a new snapshot on the host side, but
is not listed on the engine.
Any idea? I should manually merge the snapsot on the host side? If yes, any
indications on that?
Thank you for your time,
Francesco

[ovirt-users] Console - VNC password is 12 characters long, only 8 permitted
Hi all,
I'm using websockify + noVNC for expose the vm console via browser getting the
graphicsconsoles ticket via API. Everything works fine for every other host
that I have (more than 200), the console works either via oVirt engine and via
browser) but just for a single host (CentOS Stream release 8, oVirt 4.4.9) the
console works only via engine but when I try the connection via browser I get
the following error (vdsm log of the host):

The error is pretty much self explanatory but, I can't manage to figure out why
only on this server and I wonder if I can set the length of the generated vnc
password somewhere.
Thank you for your time,

[ovirt-users] Split hosts in a new engine - oVirt 4.4.5
Hello everyone! We have less than 500 hosts and ~800 vms handled by our engine and we could benefit from deploy another engine for splitting the workload (in ex.:we perform daily and weekly backup via python script, scheduled snapshot (dell+add). Is there any way for migrating/moving a host from an engine to a new one (same version, ofc)? I thought about export a backup and then import but then I'll have to "select" whihch host to import and remove all the structure (DC/cluster/host/storoge) from the old one... a bit tricky and dangerous, in my opinion. Anyone that has already done this? Thank you for your time and happy holidays!

[ovirt-users] Update path of hosted_storage domain
Hello everyone,
we have a self hosted engine environment (oVirt 4.4.5) that use a replica 2 +
arbiter glusterfs. Those servers are both glusterfs nodes and oVirt node of the
hosted engine.
For an upgrade we followed this guide
https://access.redhat.com/documentation/it-it/red_hat_hyperconverged_infrastructure_for_virtualization/1.5/html/maintaining_red_hat_hyperconverged_infrastructure_for_virtualization/replacing_primary_storage_host.
The planned upgrade was adding 2 new servers (node3 and node4) that would
replace the existing ones. We added to oVirt cluster and the glusterfs pool the
servers and moved the engine in those new hosts, without touching the underlay
glusterfs configuration. After the step n° 18 ("Reboot the existing and
replacement hosts.Wait until all hosts are available before continuing.") of
the guide we tried to start the engine but we got error on the hosted_storage
domain due to old path (the glusterfs mounted path was "node1" and the
backupvolfile was "node2").
For avoiding corruption we updated the database with the correct path and mount
options accordly with the new configuration edited in the file
/etc/ovirt-hosted-engine/hosted-engine.conf (as written in the guide).
If we try to detach the node1 brick everything stop working causing storage
error. We noticed that reference of node1 is still present in the file
/rhev/data-center/mnt/glusterSD/node1.ovirt.xyz:_engine/36c75f6e-d95d-48f4-9ceb-ad2895ab2123/dom_md/metadata,
on both of new hosts (node3 and node4).
I'll be more than glad to attach any log file needed for understanding what's
going on, and thank you whoever will take time for helping me out :)
Regards,
Francesco
