[SLA] can't start vm due to "host did not satisfy internal filter Memory."

Hi, I haven't got any trouble with ovirt for a long time but know I hit some wall: Situation: local storage DC with a single vm in it. ovirt-engine version 3.3.3 (yeah I know, old..) error i get: vm does not boot anymore. excerpt from engine.log: 2015-02-09 13:25:06,926 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (ajp--127.0.0.1-8702-14) Operation Failed: [Cannot run VM.

I could provide full logs in private, if needed. I have other vms in other virtual DCs running fine with half this amount of ram, and more. the vm got created via REST. mom seems to work just fine. any help would be appreciated. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

why is it called vdsm?
by Greg Sheremeta 16 Feb '15

Why is it called vdsm and not something a little more descriptive and project-related, like "ovirt-agent"? Greg Sheremeta Red Hat, Inc. Sr. Software Engineer, RHEV Cell: 919-807-1086 gshereme(a)redhat.com

mixing tagged and untagged vlans on a same interface
by Nathanaël Blanchet 16 Feb '15

16 Feb '15

Hi all, On a standalone libvirt/KVM, I've been used to mix tagged and untagged vlans on the same interface, the untagged vlan dedicated to the physical interface em1 and the other tagged ones to VLAN em1.X. I've just installed a new datacenter with an untagged ovirtmgmt and then realized that I've been prevented from attaching additional vlan to the same inetrface. Is there a reason for that, knowing that nothing should technically be wrong?

Issues adding a custom fencing agent
by Tobias Fiebig 15 Feb '15

15 Feb '15

Heho, i currently try to get an intelmodular server working with fencing, following: http://lists.ovirt.org/pipermail/devel/2014-February/006525.html and http://www.ovirt.org/Custom_Fencing BaseInfo: Scientific Linux 6.6 (engine/hosts) Ovirt 3.5 I added an agent with: engine-config -s CustomVdsFenceType="intelmodular" /etc/init.d/ovirt-engine restart The issue is, that the added agent always results in: 2015-02-05 19:31:08,963 ERROR [org.ovirt.engine.core.bll.FenceExecutor] (ajp--127.0.0.1-8702-1) Failed to run Power Management command on Host , no running proxy Host was found. and: Test Failed, There is no other host in the data center that can be used to test the power management settings. Picking any other agent, results in the execution of the binary on one of the cluster hosts. (which, of course fails). Replacing one of theses default-fences with a bash-script echoing $@ to a file prints nothing, additional programs (id, env) however do print sth. to the given file. Any ideas on how to continue this, to ideally get fence_intelmodular working? With best Regards, Tobias

Problem on the manager
by Massimo Mad 14 Feb '15

14 Feb '15

I have a problem on my oVirt managers, the problem is that the directory / var/lib/pgsql/data fills. Initially thinking that my file system /var/log 2Gb was too small now have increased to 4Gb and is refilled. How can I prevent this from happening, it may be due to the fact that I have implemented the backup manage with the script of backup.sh oVirt. Regards Massimo

Problem adding new host
by Juan Jose 13 Feb '15

13 Feb '15

Hello everybody, I have added a new host to my oVirt 3.5.0 and it has been added but when the installation finish the host remain in "Not operational state". The error in the engine.log file is that "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER". The host is a little old. I'm attaching part of the "lshw" host information and the engine.log files. I know that this host is not able to virtualize 64 bits VMs which it is possible to do it by the other four hosts. I would like to confirm if the problem is what I'm saying. Many thanks in advanced, Juanjo.

New user intro & some questions
by George Skorup 12 Feb '15

12 Feb '15

Hello oVirt Users Community, I've been working with Red Hat and RHEL and clones for about 11 years, though I do still consider myself amateur mostly because I'm more of a networking guy. :) One-man IT department so I get very little time to tinker. I'm evaluating oVirt (because the boss said no to VMware) and will likely begin implementation soon to virtualize our datacenter. So I have a SuperMicro Twin2 (4 nodes) system and a cheap managed L2+ switch to use for now. Dual 6-core Xeon's and 24GB per node. The two on-board 82574L's are bonded 802.3ad, no issues there (so far). I currently have two 1TB WD RE4 SATA drives configured as RAID1 using the Intel RAID BIOS in each node. I understand this is software RAID. That's all working fine and I did this so that if a drive dies then I can still boot the machine(s). I have a 500MB partition formatted as ext4 for /boot. A 48GB ext4 for the root. 24GB for swap. And finally the rest (800-something GB) is LVM and XFS for Gluster. I've been following Jason Brooks' "Up and Running with oVirt" guides (which are great, BTW!). I have the cluster up and running with CentOS 7 and oVirt 3.5, hosted-engine on CentOS 6.6 and CTDB to host a virtual IP for the engine NFS mount. There are a couple test VMs running along with the engine on various nodes. I found it interesting that I was able to upload a ripped ISO of Win 2k3 Enterprise (not SP2) and was able to successfully boot it, after which I promptly installed SP2 and oVirt guest tools. I do very little with Windows, but there's always that one remaining customer that needs IIS and we're not about to buy a new Windows Server 2012 license just for them. So anyway, I'm having a problem with node reboots. They simply will not shut down and reboot cleanly. Instead, it looks like they hang after all processes are shut down, or at least attempted to be shut down. Then after a couple minutes, the hardware watchdog resets the system. I've came to the conclusion that sanlock and/or wdmd is causing the hangup. I'm guessing an active but non-responsive NFS mount is the culprit, possibly the ISO domain NFS mount which is on the engine? I've tried manually shutting down all oVirt, VDSM, etc. processes, unmounting all NFS shares, but it seems sanlock still has a hold on something in /rhev/.. I've Google'd a bit and have come across posts about this as well. Any tips here? Then I experienced something else odd yesterday. I did a yum update for the glibc vulnerability stuff. Gluster was updated as well which really threw a wrench into things because I wasn't paying attention and quorum broke, etc. I got that fixed. Rebooted all nodes (which is when I found the sanlock/watchdog problem). Nodes 2, 3 and 4 came back up, but node1 did not. I logged into the IPKVM console and found that it had no network configuration. All /etc/sysconfig/network-scripts/ifcfg-* files were gone. I was able to manually reconfigure the physical interfaces, set the bonding back up and add the ovirtmgmt bridge. But then the engine reported the host as non-operational due to '..does not comply with cluster default networks... ovirtmgmt missing' which I was able to resolve by reconfiguring the host's network config within the engine GUI and all is now well. I'm just curious how/why the ifcfg files were wiped out? I haven't touched the network config on any hosts since running hosted-engine --deploy. Please forgive my ignorance and point me to the correct place if these issues have been discussed and/or resolved already. And overall I'm very much liking oVirt, especially as a viable and cost-effective alternative to vSphere. Thanks, George
