moving storage away from a single point of failure
by Robert Story 25 Sep '15

--Sig_/d8.0dmwks3vvUk8CoFxP3Dz Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi, I'm running oVirt 3.5 in our lab, and currently I'm using NFS to a single server. I'd like to move away from having a single point of failure. Watching the mailing list, all the issues with gluster getting out of sync and replica issues has me nervous about gluster, plus I just have 2 machines with lots of drive bays for storage. I've been reading about GFS2 and DRBD, and wanted opinions on if either is a good/bad idea, or to see if there are other alternatives. My oVirt setup is currently 5 nodes and about 25 VMs, might double in size eventually, but probably won't get much bigger than that.

VNC console behind NAT
by Alan Murrell 25 Sep '15

25 Sep '15

Hello, I am able to connect to SPICE that is behind a NAT (via Squid), but am wondering if there is a way to do it with VNC as the console option? I thought I had this working at one point, several installs ago, but it doesn't seem to be the case currently. When I do try to connect to a VM configured to use VNC as the console option, the remote-viewer screen opens, says "Connecting to graphic server", then after about 30 seconds or so says it is unable to connect to the graphic server. Thanks! :-) Regards, Alan

HI While mounting the EXport Domain to the different engine getting below error, Error while executing action New NFS Storage Domain: Error in creating a Storage Domain. The selected storage path is not empty (probably contains another Storage Domain). Either remove the existing Storage Domain from this path, or change the Storage path). -Nagaraju

HA - Fencing not working when host with engine gets shutdown
by Michael Hölzl 25 Sep '15

25 Sep '15

Hi all, we are trying to setup an ovirt environment with two hosts, both connected to a ISCSI storage device, a hosted engine and power management configured over ILO. So far it seems to work fine in our testing setup and starting/stopping VMs works smoothly with proper scheduling between those hosts. So we wanted to test HA for the VMs now and started to manually shutdown a host while there are still VMs running on that machine (to simulate power failure or a kernel panic). The expected outcome was that all machines were HA is enabled, are booted again. This works if the machine with the failure does not have the engine running. If the machine with the hosted engine VM gets shutdown, the host gets in the "Not Responsive state" and all VMs end up in an unkown state. However, the engine itself starts correctly on the second host and it seems like it tries to fence the other host (as expected) - Events which we get in the open virtualization manager: 1. Host hosted_engine_2 is non responsive 2. Host hosted_engine_1 from cluster Default was chosen as a proxy to execute Status command on Host hosted_engine_2. 3. Host hosted_engine_2 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" 4. Host hosted_engine_2 is not responding. It will stay in Connecting state for a grace period of 124 seconds and after that an attempt to fence the host will be issued. Event 4 is continuously coming every 3 minutes. Complete engine.log file during engine boot up: http://pastebin.com/D6xS3Wfy So the host detects the machine is not responding and wants to fence it. But although the host has power management configured over ILO, the engine thinks that it is not. As a result the second host does not get fenced and VMs are not migrated to the running machine. In the log files there are also a lot of time out exception. But I guess that this is because the host cannot connect to the other machine. Did anybody face similar problems with HA? Or any clue what the problem might be? Thanks, Michael ---- ovirt version: 3.5.4 Hosted engine VM OS: Cent OS 6.5 Host Machines OS: Cent OS 7 P.S. We also have to note that we had problems with the command fence_ipmilan at the beginning. We were receiving the message "Unable to obtain correct plug status or plug is not available," whenever the command fence_ipmilan was called. However, the command fence_ilo4 worked. So we use a simple script for fence_ipmilan now that calls fence_ilo4 and passes the arguments.

Older hardware deployment

This is a multipart message in MIME format. ------=_NextPart_000_00D6_01D0F555.6C3D0CF0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit I've searched on this issue all over the place and not found a full answer. I've got a lab with older Dell PE860 servers with Pentium D processors. We are attempting to prove out that we can move from VMware to KVM and oVirt, but with 3.5 we can't get these servers to enter into a cluster due to the age of the processors. I've seen it referenced in a few list entries to modify 'the database' to put CPUInfo entries in for the processor capabilities of this processor, but it is unclear to me and I've been unable to find any documentation that speaks to what database and how to modify it safely. I know we could update these servers and get better power consumption, heat generation, etc., but it's not in the cards and I can't move my newer servers until we prove it out with these older ones, which ran ESXi 5.5 with absolutely no issue. This cluster will be a functional test and small tools cluster ultimately, so I don't really care about their lower end specs, either. Would installing something older than 3.5 help me here? Or is there some doc somewhere I've just not found that describes this process of updating the DB with these CPU parameters.

Systemd-Script to put the node in "maintenance" on shutdown
by Luca Bertoncello 25 Sep '15

25 Sep '15

Hi again, I'm trying to write a systemd-script (for CentOS7) in order to automatically put the host in "maintenance" on shutdown and to activate it after boot. I wrote a python-script that to that and it works so that I can start it and see the host in "maintenance" and having all VMs migrated. Unfortunately I can't call this script on shutdown/reboot and wait until all VMs are migrated and the host is in maintenance. Here my script: [Unit] Description=oVirt interface for managing host After=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service Wants=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service [Service] Type=simple RemainAfterExit=yes ExecStart=/usr/local/bin/ovirt-maintenance.sh active ExecStop=/usr/local/bin/ovirt-maintenance.sh maintenance KillMode=none [Install] WantedBy=multi-user.target Could someone help me and say what I'm doing wrong?

Virtual appliance import question/problem
by Maurice James 25 Sep '15

------=_Part_674_1103437547.1442854627811 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit I have a virtual mail security appliance that I am trying to import into oVirt 3.5.4. The appliance was built for kvm. it has a total of 5 scsi disks. I can convert and copy the OS disk only because it expands its self to full size. The first problem that I have is that the disks expand to their full size when I convert the to an oVirt format OS Disk mail.qcow2 (74M) converts to main.img (294M) Storage disks 250.qcow2 (256K) converts to 250.img (250GB) 1024.qcow2 (256K) converts to 1024.img (1TB) 2048.qcow2 (256K) converts to 2048.img (2TB) 4096.qvow2 (256K) converts to 4096.img (4TB) 8192.qcow2 (256K) converts to 8192.img (8TB) The second problem is that these disks are scsi and ti does not seem to work using the virtio-scsi selection. I tried selecting the IDE option, but there is a limit to the number of IDE disks that I can use. Virtualbox has no issues running the appliance that was distributed in the ova format.
