Local and remote storage?
by Pat Riehecky 24 Feb '15

24 Feb '15

Hello, I've run into an "odd" problem with oVirt 3.5.1. I've two sets of VMs: A) some fairly critical VMs which need HA and have access to shared storage B) some less important systems which can be reconstructed in the event of a disaster My plan was to use the slack disk on my oVirt nodes to host the 'B' systems while still allowing the 'A' systems to run there. This seems to not be allowed[1]. Is there a way I can utilize both the spare disk on my compute nodes and have HA configured for some VMs with shared storage?

Hi, Currently I'm looking for new solution for providing VPS-s to my organization users, we don't need biling infrastructure.. Does anyone has case of ovirt as VPS management and user interface (please provide me some feedbacks)? And another question, what about integration with SingleSignOn infrastructure like shibboleth, based od SAML2?

Exporting a VM's disks
by John Gardeniers 22 Feb '15

22 Feb '15

Hi All, Having recently had a need to manually export a VM from our RHEV environment I searched for a way to identify the VM's disks with the files on the storage system. The search led me to http://rhevdup.blogspot.com.au/2013/05/manual-export-of-vm-from-rhev.html but unfortunately, the script in that post only lists the first drive for a VM, making it less than useful for exporting VMs with multiple drives. Inspired by that post I wrote my own version in Perl (I detest Python). The script works on our RHEV 3.4 with a Gluster storage back end. I would greatly appreciate it if some of you could test it on other RHEV/Ovirt versions and on different storage systems. Thanks for any feedback. regards, John #! /usr/bin/env perl # Run this script on the RHEV/Ovirt engine (management) machine # # Find the files on the storage which belong to a VM's disk(s) # Input parameter: A single VM name (case sensitive) use DBI; my $vm = shift or die "No VM specified\n"; my $conf = '/etc/ovirt-engine/engine.conf.d/10-setup-database.conf'; my $host = 'localhost'; my $db; my $user; my $pass; my $port = 5432; open my $fi, '<', $conf or die "Can't read $conf\n"; while(<$fi>) { my $line = $_; $host = $1 if($line =~ /ENGINE_DB_HOST="(.*)"/); $db = $1 if($line =~ /ENGINE_DB_DATABASE="(.*)"/); $user = $1 if($line =~ /ENGINE_DB_USER="(.*)"/); $pass = $1 if($line =~ /ENGINE_DB_PASSWORD="(.*)"/); $port = $1 if($line =~ /ENGINE_DB_PORT="(.*)"/); } die "Unable to get all database details\n" if(!$db || !$user || !$pass); my $dbh = DBI->connect("dbi:Pg:dbname=$db;host=$host;port=$port", $user, $pass, {AutoCommit=>1,RaiseError=>1,PrintError=>0}); die "Error connecting to the database\n" if(!$dbh); # Get the device ID my $sql = "select device_id from vms_for_disk_view where array_vm_names = '{$vm}'"; my @row = $dbh->selectrow_array($sql); my $vm_id = $row[0]; if($vm_id) { print "\nVM ID: $vm_id\n"; # Get the drive ID(s) $sql = "select image_guid, to_char(size/1024/1024/1024.0, '999G999D99'), to_char(actual_size/1024/1024/1024.0, '999G999D99'), storage_name from images_storage_domain_view where vm_names = '$vm' and entity_type = 'VM'"; my $sth = $dbh->prepare($sql) || die "Error preparing the SQL string \"$sql\"\n$dbh::errstr"; print "\nError executing $sql\n$DBI::errstr\n\n" unless $sth->execute(); print "Disk ID(s): "; my $cnt = 0; while (@row = $sth->fetchrow_array) { print " " if($cnt++); print "$row[0], $row[1]GB allocated, $row[2]GB actual, on $row[3]\n"; } $sth->finish; print "\n"; } else { print "\nVM \"$vm\" not found.

It is possible - Ovirt ? different CHAP authentication credentials
by Eduardo Terzella 22 Feb '15

22 Feb '15

Hello, We have a requirement where when we add storage to our Ovirt cluster, each node in the cluster must use a different iSCSI CHAP username. This unfortunately does not work correctly when adding storage from the web interface for Ovirt as it only allows you to specify a shared username/password combination. We need to be able to use different CHAP authentication credentials when we add storage to Ovirt
