OVIRT-3.5-TEST-DAY-3 Instance types
by Alexander Wels 17 Sep '14

17 Sep '14

Hi, For the 3rd test day I was assigned to test the new instance types. The following instance types are available: custom: Aka what it was before tiny: 512M memory and 1 cpu small: 2048M memory and 1 cpu medium: 4096M memory and 1 cpu large: 8192M memory and 2 cpus x-large: 16384M memory and 4 cpus I verified that each selection modifies the properties accordingly. As well as the ability to change instance types after creating the VMs and that those changes are reflected. If you change a property lets say the memory after selecting an instance type it changes to custom automatically but keeps all the other pre-selected options the same. The only thing that won't change the instance type to custom if you change the 'optimized for' from server to desktop. This normally changes the soundcard enabled check box in the console tab but if an instance type is selected it doesn't. I don't know if this is on purpose or not. So all in all it works as expected, with a potential minor issue. Alexander

OVIRT-3.5-TEST-DAY-3 - Providing Neutron Appliance
by ybronhei 17 Sep '14

17 Sep '14

Hey, following the great demo in http://youtu.be/naLFSFwHI94 we successfully managed to use neutron to setup isolates network for 2 vms by using the neutron appliance image we didn't open new bugs on it, but we plan to use and play with it later on and we'll update if something will be found we saw that the mirrors for f19 are broken but it doesn't worth a bug, just wiki update (in http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-releas…) -- Yaniv Bronhaim.

OVIRT-3.5-TEST-DAY-3: backup/restore and disaster recovery
by Simone Tiraboschi 17 Sep '14

17 Sep '14

Hi, today I had to test how to recover a broken system using backup/restore tool [1] or disaster recovery procedure [2]. Unfortunately I really had a lot of troubles just trying to setup my test environment so no good news on that side. I was using two host: one for the engine, the other as an hypervisor. Both with latest fedora 19 updates. For a fault of mine I add oVirt 3.5 RC2 repository on the engine host but I forgot to do the same on the second host and it generates a lot of problems. I installed the ovirt engine, release 3.5 RC2, on the first host and from the web admin UI I was trying to add the second host. I discovered that using jsonrpc mode it doesn't check/enforce or at least advice about cluster compatibility level failing silently. I opened a bug for that [3]. Than I start using xmlrpc mode that suggested me to downgrade the cluster compatibility mode to 3.3; I did that but it still failed adding my host apparently due to SELinux or Gluster errors; I opened a bug also for that [4]. So I understood that I forgot to add oVirt 3.5 repo on the second host; I opened a bug against host-deploy with install rpms but doesn't handle RPM repos. On my opinion it would make the setup more user friendly or at least more controllable for us [5]. So I added the yum repository and I tried again; I noticed that host-deploy upgrades vdsm stuff but it wasn't enough to get 3.5 compatibility level so, investigating it a bit, I noticed that host-deploy upgrades vdsm stuff but completely ignores libvirt one generating a nonworking setup; I opened a bug also for that [6]. At the end, after manually upgrade libvirt rpms I was able to add my host. Than I briefly tested backup/restore and disaster recovery procedures which seam to work as expected. So, at the end, on my opinion we have still to work a bit more to make the setup more user friendly.

OVIRT-3.5-TEST-DAY-3: replace XML-rpc with JSON-rpc
by Francesco Romani 17 Sep '14

17 Sep '14

Hi everyone of this test day I played with the new JSON-rpc transport, which is enabled by default. I set up from scratch two hypervisors running on RHEL 6.5, while Engine was running on F19. I created everything from scratch and tested all the flows I known good enough, including less-then-common stuff. The list includes creating storage domains, VMs, hotplug/unplug disks, snapshots, migration, hibernation and dehibernation. On top of that, I prepared an environment to run more tests, that included create 200 VMs, started/stopped 100 of them to test. I kept an eye on the logs other than Engine. Everything I tried went OK, and logs look good to me. I run in a few hiccups, which I mention for the sake of completeness: - VDSM refused to start or run VMs initially: libvirt config included relics from past environment on the same box, not JSON-rpc fault. Fixed with new config and (later) a reboot. - Trying recovery, Engine took longer than expected to sync up with VDSM. I have not hard data and feeling is not enough to file a BZ, so I didn't. - Still trying recovery, one and just one time Engine had stale data from VDSM (reported two VMs as present which actually aren't). Not sure it was related to JSON-rpc, can't reproduce, so not filed a BZ. Since I need to continue profiling anyway (better late than never I guess), I include a couple of test to see if JSON-rpc makes any difference to JSON-rpc. Results will be posted on devel(a)ovirt.org and/or on the oVirt wiki. -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

[OVIRT-3.5-TEST-DAY-3] dwh and reports on separate host
by Martin Sivak 17 Sep '14

17 Sep '14

Hi, I installed fresh engine on CentOS 6.5 (inside a VM) and dwh + reports to other CentOS 6.5 VM. Except being a bit confused by the certificate signing step during the setup all went well and I can see that the dwh service is running and I can access the reports site. I started in the afternoon, because I had to reinstall my hosts first, so I might try poking around tomorrow as well. Also I do not have extra hosts atm, but I hope to have my nested virtualization environment back tomorrow to actually put some data to the reports. -- Martin Sivák msivak(a)redhat.com Red Hat Czech RHEV-M SLA / Brno, CZ

Virtual Machines reporting as paused
by Thomas Scofield 17 Sep '14

17 Sep '14

A large number of my virtual machines are reporting in a paused state but they are actually up and running. Unfortunately I don't look at this cluster very often so I don't know exactly when it got into this state, I believe it may have happened a couple months back when I deployed a change to /etc/vdsm/vdsm.conf to throttle virtual machines migrations. I deployed this change via puppet and had puppet cycle the vdsm daemon. All of the vdsm daemons in the cluster were restarted in a short period of time. Since this happened some time back all the logs have rotated off. I have tried restarting vdsmd and libvirtd, but that doesn't appear to return the virtual machines to an up state. The output of "vdsClient -s 0 getAllVmStats" reports them as paused, "virsh -r list --all" reports them as running. From the GUI I can click run and the VM will show “Up” in the GUI and vdsClient. But if I restart vdsm, the VM's revert back to displaying a paused state. I did find that the *.recovery files in /var/run/vdsm contain a status of Paused even when the GUI and vdsClient are reporting it as up. I did try and change the status in this file while vdsm was down and then start vdsm, but it had no effect and the entry in the *.recovery file which reverted to paused. p335 sasS'status' p336 S'Paused' Any idea what might have caused the VM's to report as paused and how to recover from it? I am running ovirt-3.3.4-1 and vdsm-4.13.3-4

VM Network Interfaces - bad cluster network and VLAN assignment
by J. Mikulec 17 Sep '14

17 Sep '14

Hello, I have 4 Cluster networks and I am trying to add 2 NICs to VM now: nic0 -> br0 nic1 -> br1 At ovirt-engine it seems ok, but assignment in qemu is incorrect - going to this: nic0 -> br1 nic1 -> br0 So nics belongs to incorrect bridges and so incorrect VLANs. It does oVirt totally unusable for me (we strictly use 0 network for public IPs and 1 for intranet use) :( With one NIC I not see this problem. http://tinypic.com/view.php?pic=29pzxbr&s=8#.VBjLUxYoEiw http://tinypic.com/view.php?pic=2hdd07m&s=8#.VBjLgRYoEiw Thank for help.

Cannot create disk image on storage domain NOT master
by Gabi C 17 Sep '14

17 Sep '14

Hello! - 1 oVirt Engine (not hosted), 4 nodes, 3 in "Default" datacenter, 1 in a local-storage type datacenter; - Recently upgraded from 3.4.2 to 3.4.3; "Default"Datacenter has, along "mandatory"ISO and Export domain, two storage domains "storage_gluster2" aprox 550Gb and "storage_gluster3" aprox 130 GB.

Restart hosted-engine However online reading says that this won't work because the storage domain= info is stored in different places. Is there a procedure or anything for = how to do this?

cloud-init issues on fedora ovirt
by Pat Pierson 16 Sep '14

16 Sep '14

I am running ovirt 3.4.3 on a Fedora 19 manager and have 1 node running Fedora 19 as well. I am attempting to get cloud-init to work on a CentOS VM but I am running into issues. I can see where in the log it mounts /dev/sr1 to /tmp/tmp_random_location and where it reads the meta-data.json and user_data from that location but after it unmounts it moves on to /var/lib/cloud/data/instance-id and returns "No instance datasource found! Likely bad things to come!" Has anyone seen this before? Am I missing something? -- Patrick Pierson

Gluster command [<UNKNOWN>] failed on server
by Nathan Stratton 16 Sep '14

16 Sep '14

I gave up on trying to import my gluster config into ovirt so I tried a fresh install and just set the gluster peers without creating any volumes. However none of my hosts will activate, when I try I get: Gluster command [<UNKNOWN>] failed on server virt01a. The only thing I see in vdsm.log is: Thread-3542::DEBUG::2014-09-14 14:35:26,946::__init__::467::jsonrpc.JsonRpcServer::(_serveRequest) Calling 'GlusterHost.list' in bridge with {} Nothing else, can anyone point me into the right direction on how to debug this with so little information? ><> nathan stratton | vp technology | broadsoft, inc | +1-240-404-6580 | www.broadsoft.com

Can't understand Template Sub Version
by John Xue 16 Sep '14

16 Sep '14

Hi, All I'm using oVirt Engine Version: 3.4.3-1.el6, but I can't understand this function. I have 3 question: 1 How to change a vm to use other template sub version? I don't want to build a new vm from new template version. 2 How to update a pool to use other template sub version? I'm using non latest version, and shutdown all vm of this pool, but I still can't change template version. 3 How to create a pool with disable stateless function? In the property of template vm, I'm sure I don't enable "stateless". But in the testing, I found all the vm are stateless vm. How to disable it, or I'll lost all config and personal data. Thank you very much! -- Regards, John Xue

Move ovirt-engine to a new server
by Neil 16 Sep '14

16 Sep '14

Hi guys, Please could someone try assist me. I'm starting to lose hair over this :) I'm trying to migrate my current engine to a new host with the same OS and hostname. Centos 6.5, ovirt-engine-3.4.3-1.el6.noarch I've installed all the packages, I run engine-setup and go through the options keeping the details the same as before, I then restore my config back to /etc/ovirt-engine as well as to /etc/pki/ovirt-engine, but when it gets to trying to restore my database I get the following error... [root@backup dbscripts]# ./restore.sh -u postgres -f /mnt/fw-ovirt-backup/engine-db-2014-09-15-16-48.sql psql: FATAL: Ident authentication failed for user "postgres" Database engine does not exist, please create an empty database named engine. [root@backup dbscripts]# su - postgres -c "psql -d template1 -c 'drop database engine;'" DROP DATABASE [root@backup dbscripts]# su - postgres -c "psql -d template1 -c 'create database engine owner engine;'" CREATE DATABASE [root@backup dbscripts]# ./restore.sh -u postgres -f /mnt/fw-ovirt-backup/engine-db-2014-09-15-16-48.sql psql: FATAL: Ident authentication failed for user "postgres" Database engine does not exist, please create an empty database named engine. or even [root@backup dbscripts]# ./restore.sh -u engine -f /mnt/fw-ovirt-backup/engine-db-2014-09-15-16-48.sql psql: FATAL: Ident authentication failed for user "engine" Database engine does not exist, please create an empty database named engine. This is my pg_hba.conf as well.. # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all ident host engine engine 0.0.0.0/0 md5 host engine engine ::0/0 md5 # IPv4 local connections: host all all 127.0.0.1/32 ident # IPv6 local connections: host all all ::1/128 ident I've done this a couple time before and haven't encountered this issue, so it seems rather odd. Thanks. Regards. Neil Wilson.
