Frequent events seen like VM "vmname" is not responding
by manoj.sharma99765＠gmail.com
I am using oVirt Open Virtualization Manager Software Version:4.4.6.8-1.el8 and we have single node running on oVirt Node 4.4.6.
We are facing slowness while using VM and also we face connection reset issue between VM and Target servers ( Nexus )
We are getting below logs in ovirt manager events
VM "vmname" is not responding
Getting this for all the running VMs .
We checked resources and utilization of the node everything seems very normal. Could you please guide on how can we solve/debug further on this ?

Cannot activate a Storage Domain after an oVirt crash
by nicolas＠devels.es
Hi,
We're running oVirt 4.3.8 and we recently had a oVirt crash after moving
too much disks between storage domains.
Concretely, one of the Storage Domains reports status "Unknown",
"Total/Free/Guaranteed free spaces" are "[N/A]".
After trying to activate it in the Domain Center we see messages like
these from all of the hosts:
VDSM hostX command GetVGInfoVDS failed: Volume Group does not exist:
(u'vg_uuid: Usi3y8-S4eq-EXtl-FA58-MA3K-b4vE-4d9SCp',)
I tried putting the Storage Domain in maintenance and it fails with
messages like:
Storage Domain iaasb13 (Data Center KVMRojo) was deactivated by
system because it's not visible by any of the hosts.
Failed to update OVF disks 8661acd1-d1c4-44a0-a4d4-ddee834844e9, OVF
data isn't updated on those OVF stores (Data Center KVMRojo, Storage
Domain iaasb13).
Failed to update VMs/Templates OVF data for Storage Domain iaasb13
in Data Center KVMRojo.
I'm sure the storage domain backend is up and running, and the LUN being
exported.
Any hints how can I debug this problem and restore the Storage Domain?
Thanks.

I'm in trouble....
by Wesley Stewart
Luckily this is for a home lab and nothing critical is lost. However I was
trying to change the subnet my host was on. And I found out that you
cant do that. So I reverted back but my hosted engine wasnt happy about my
NFS mounts.
so I did a engine-cleanup and an engine-setup. Went through the prompts
and thought nothing of it. I logged back into ovirt, and everything looks
like it was a brand new install. No VMs or anything. I believe I have a
fairly recent backup somewhere... trying to track that down, but it's not
looking good.
Currently running 4.3.10. I have been planning out my 4.4 upgrade
anyways. I would prefer to not start from scratch... but if I do it is not
the end of the world, will just take a lot more time.
Looking for some guidance! Thank you.

Hi Tommy,
Yes, you can change root password on all hosts with no problem.
Your cluster will keep working fine.

I have successfully installed and deployed OLVM, where the Engine uses a
separate physical server and the virtual machines work on other worker
servers.
Due to the company's internal security policy, I now need to change the root
user password for all servers. Is that ok?
Will cluster running be affected?
Thanks!

My understanding, is that OLVM/oVirt use the root password to push it's SSH
credentials at first login. Once that is done, all other SSH access is
though those credentials.
You should be able to change the root password without issue.

REST API import VM from Export Domain
by christian.peater＠gmx.de
i'm using OLVM 4.3.10 oVirt and i'm trying to import a VM from the Export Storage Domain with the REST API.
curl command is:
curl \
-X POST \
--header "Version:4" \
--header "Accept:application/xml" \
--header "Content-type:application/xml" \
--user $_OLVM_USERNAME:$_OLVM_PASSWORD \
--data '
<action>
<storage_domain>
<name>'$DST_SD'</name>
</storage_domain>
<cluster>
<name>'$CLUSTER'</name>
</cluster>
<clone>true</clone>
<vm>
<name>'$VM_NAME'</name>
</vm>
</action>
'
https://$_OLVM_HOSTNAME/ovirt-engine/api/storagedomains/$SRC_SD_ID/vms/$SD_VM_ID/import
Response is:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not understand.<br />
</p>
</body></html>
When i use the same syntax to just get a list of importable VMs there is no error and the Response is a xml entity.
Any idea?
