Stalled disk migration
by Nicolás 09 Oct '16

09 Oct '16

Hi, We've done a major datastore migration recently between 2 iSCSI-based datastores. We've successfully migrated 35 machines, however, 5 of them seem to have stalled. All we can see in the events tab tab is: Moving Disk bla_Disk1 from iscsi01 to iscsi02 Disks are small enough (25-27Gb) to assume this won't progress since it's been more than 30 hs. since the migration began, other VMs took approximately 1-1.5 hours to fully migrate a disk, so this seems to be stalled. The bad thing is that I can't find a way to "unstall" it. Disks are in a perpetual "migrating" status and there's no way to stop the migration (at least from the webadmin). I don't actually care if stopping the migration breaks those 5 machines since they are disposable, I just need to stop that event. I already tried restarting the ovirt-engine and it didn't work. Log doesn't seem to provide nothing relevant. Is there a way to do that? I wouldn't mind if I need to modify some record directly into the DB. Thanks! Nicolás

They are to be removed soon. In fact we already stopped them to track the remaining users, and no one complained. It can be restarted on demand before the removal date. On 2016-10-26 the resources will be purged. Backup has been made, so nothing is lost but unless there is a good reason it won't be used. Btw, the wiki@ mailing-list was unused and is now read-only.

documentation change suggestion / question
by Charles Kozler 08 Oct '16

08 Oct '16

Googling "ovirt windows agent" this is the first link that pops up: http://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-win… This doc seems non-intuitive and over complicated Specifically, the RedHat documentation that is 4 links below is simple as "install this package and mount the iso": https://community.redhat.com/blog/2015/05/how-to-install-and-use-ovirts-win… The former was updated as early as June of this year 1.) The RedHat document worked for me so I dont think oVirt 4.x cant use the same 2.) Why have separate areas of documentation that are so different from each other? This has caused me issues in the past whereby I found RH docs that were much more clear and concise 3.) Is there anyone who might want to merge RH docs with oVirt docs where the RH docs are better than oVirt? Thanks so much for providing such a great product! I just feel sometimes the docs are a little more developer-centric whereas the RedHat docs are more easily readable

VMs paused due to IO issues - Dell Equallogic controller failover
by Gary Lloyd 07 Oct '16

07 Oct '16

Hi We have Ovirt 3.65 with a Dell Equallogic SAN and we use Direct Luns for all our VMs. At the weekend during early hours an Equallogic controller failed over to its standby on one of our arrays and this caused about 20 of our VMs to be paused due to IO problems. I have also noticed that this happens during Equallogic firmware upgrades since we moved onto Ovirt 3.65. As recommended by Dell disk timeouts within the VMs are set to 60 seconds when they are hosted on an EqualLogic SAN. Is there any other timeout value that we can configure in vdsm.conf to stop VMs from getting paused when a controller fails over ? Also is there anything that we can tweak to automatically unpause the VMs once connectivity with the arrays is re-established ? At the moment we are running a customized version of storageServer.py, as Ovirt has yet to include iscsi multipath support for Direct Luns out of the box. Many Thanks *Gary Lloyd* ________________________________________________ I.T.

VM SSO
by Maxence Sartiaux 07 Oct '16

07 Oct '16

Hello, I try to use the VM SSO but no login, still on the logon screen ... I'm on ovirt 4.0.3, connected to an AD (Samba 4.5) + VMs Windows 7/10 stateless sysprep-ed to integrate to the domain and obviously the guest-agent is installed. My AD user can connect to the user panel, take a vm and connect to the console but no sign on on the windows. (the "Connect Automatically" option is ticked) Also, i don't know why but my username on ovirt panel has a double domain "u1@labo.lan@labo.lan" <- is this my problem ? The AD configuration is the configuration from the extension setup wizard, no custom config, no mapping Any ideas ? Thank you

VDSM Network Interface configuration
by Maton, Brett 07 Oct '16

07 Oct '16

Where is the configuration that VDSM uses to generate ifcfg files? My nameservers have moved and it seems to regenerate the ifcfg (ovirtmgmt) file overwriting the changes with the correct name servers in when the server is rebooted and s putting in the wrong (old) nameserver addresses. Where can I fix this ? Thanks

Correct recovery procedure of the oVirt Hosted Engine 4.0
by aleksey.maksimov＠it-kb.ru 06 Oct '16

06 Oct '16

Hello oVirt guru`s! My Hosted Engine VM located on a dedicated LUN FC Storage. I do daily data backups (on NFS share) with the command: /usr/bin/engine-backup --mode=backup --scope=all --file=$BcpFileName.xz --log=$BcpFileName.log --archive-compressor=xz --files-compressor=None However, I don't know what would be the correct procedure to recover, because in different manuals outline the various steps. For example, there is information that I have to do configure postgresql (with password from file files/etc/ovirt-engine/engine.conf.d/10-setup-database.conf) before restoring (engine-backup --mode=restore): https://www.ovirt.org/documentation/admin-guide/hosted-engine-backup-and-re… And at the same time, in another document, there are no such steps: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/singl… What should be the correct procedure for the recovery of Hosted Engine 4.0 ?

Hi, i'd like to create this basic setup: Two hosts with SLES 11 SP4, 10-15 guests (Windows 7, SLES, Ubuntu). SAN with several TB, attached via FC, formatted with OCFS2. VM's will run with kvm and libvirt. I'd like to have live migration. Would ovirt be possible in this setup, would i have a benefit ? Easy administration, s.th. like that ? Thanks.

Hi guys, When the engine lives under engine.sub.sub.sub.domain.tld is it possible to add an extra alt hostname to it so we can add a certificate for engine.domain.tld ? I hope someone can point this out. Cheers, Matt

hosted-engine and GlusterFS on Vlan help
by Hanson 05 Oct '16

05 Oct '16

Hi Guys, I've converted my lab from using 802.3ad with bonding>bridged vlans to one link with two vlan bridges and am now having traffic jumping to the gateway when moving VM's/ISO/etc. 802.3ad = node1>switch1>node2 801.1q = node1>switch1>gateway>switch1>node2 I assume I've setup the same vlan style, though this time I used the gui on the initial host install... setting up the vlans with their parent being eth0. Hosted-engine on deploy then creates ovirtmgmt on top of eth0.11 ... Switch is tagged for vlans 10 & 11. Including a PVID of 11 for good measure. (Gluster is vlan 11) I'd expect the traffic from node to node to be going from port to port like it did in 802.3ad, what have I done wrong or is it using the gui initially? This is how the current setup looks: /var/lib/vdsm/Persistent/netconf/nets/ovirtmgmt: { "ipv6autoconf": false, "nameservers": [], "nic": "eth0", "vlan": 11, "ipaddr": "10.0.3.11", "switch": "legacy", "mtu": 1500, "netmask": "255.255.255.0", "dhcpv6": false, "stp": false, "bridged": true, "gateway": "10.0.3.1", "defaultRoute": true } /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt: # Generated by VDSM version 4.18.13-1.el7.centos DEVICE=ovirtmgmt TYPE=Bridge DELAY=0 STP=off ONBOOT=yes IPADDR=10.0.3.11 NETMASK=255.255.255.0 GATEWAY=10.0.3.1 BOOTPROTO=none DEFROUTE=yes NM_CONTROLLED=no IPV6INIT=no VLAN_ID=11 MTU=1500 Thanks!!

oVirt 3.6.4 / PXE guest boot issues
by Alan Griffiths 04 Oct '16

04 Oct '16

A explanation/work-around for this issue raised back in April. It seems that if, in UCS, you configure a vNIC with a single native VLAN it will still add an 802.1q header with tag 0 - possibly to do with QoS. And this extra header prevents iPXE from parsing the DHCP response. The solution for me was to present all VLANs on a single trunked vNIC to the blade and configure VLAN tagging as per normal. The result is the tags are stripped off the packets before being passed to the VM and DHCP now works. The same issue applies to VM-FEX as packets coming off the VF will have the 802.1q header. The only solution I can see here is to configure a bridged interface for initial build of the VM and then switch to VM-FEX afterwards. I found a discussion on the iPXE mailing list about addressing the vlan 0 issue, but I could see no agreed solution. http://lists.ipxe.org/pipermail/ipxe-devel/2016-April/004901.html Alan

Re: [ovirt-users] DISCARD support?

Here is what I learned from many BZ and mailing list posts readings. I'm not working at Redhat, so please correct me if I'm wrong. We are using thin-provisioned block storage LUNs (Equallogic), on which oVirt is creating numerous Logical Volumes, and we're very happy with it. When oVirt is removing a virtual disk, the SAN is not informed, because the LVM layer is not sending the "issue_discard" flag. /etc/lvm/lvm.conf is not the natural place to try to change this parameter, as VDSM is not using it. Efforts are presently made to include issue_discard setting support directly into vdsm.conf, first on a datacenter scope (4.0.x), then per storage domain (4.1.x) and maybe via a web GUI check-box. Part of the effort is to make sure every bit of a planned to be removed LV get wiped out. Part is to inform the block storage side about the deletion, in case of thin provisioned LUNs. https://bugzilla.redhat.com/show_bug.cgi?id=1342919 https://bugzilla.redhat.com/show_bug.cgi?id=981626 -- Nicolas ECARNOT On Mon, Oct 3, 2016 at 2:24 PM, Nicolas Ecarnot <nicolas(a)ecarnot.net <mailto:nicolas@ecarnot.net>> wrote: Yaniv, As a pure random way of web surfing, I found that you posted on twitter an information about DISCARD support.

Re: [ovirt-users] Migrate machines in unknown state?

Is there a mechanism to prevent fencing on this scenario? In two of our customers' production systems we've experienced this exact behavior (i.e. engine fencing the host while restarting vdsm service manually) for a number of times, and we were specifically advised by Red Hat Support to turn off PM before restarting service. I'd like to to know if we have a better / easier way to restart vdsm. btw, b oth of the environments were RHEV-H based RHEV 3.5 clusters, and both we were busy systems, so restarting vdsm service took quite a long time. I'm guessing this might be a factor.
