vdsm hook
by 董青龙 21 Aug '18

21 Aug '18

Hi all, I want to write a hook in which name or id of the vm can be acquired and the hook should be executed before the vm shutdown. I could acquire name or id of the vm in a before_vm_start hook using "hooking.read_domxml()". However, it did not work in a before_vm_destroy hook. So what should I do? Can Anyone give me some advice? Thanks a lot!

how to reset engine-config parameter?
by Gianluca Cecchi 21 Aug '18

21 Aug '18

Hello, I tried to setup UserDefinedVMProperties to disable macspoofing for a vm that has to work as hypervisor. Then I remembered suggestion of Simone about creating vnic profile as an alternate method and set there the filter. I think I have done something wrong because if I create now a new vm and try to power on it I get VM test is down with error. Exit message: Hook Error: ('',). Perhaps I failed the syntax to reset the value of UserDefinedVMProperties ? I used [root@ovirt ~]# engine-config -s "UserDefinedVMProperties=" Please select a version: 1. 4.1 2. 3.6 3. 4.0 4. 4.2 4 [root@ovirt ~]# engine-config -g UserDefinedVMProperties UserDefinedVMProperties: version: 4.1 UserDefinedVMProperties: version: 3.6 UserDefinedVMProperties: version: 4.0 UserDefinedVMProperties: version: 4.2 [root@ovirt ~]# systemctl restart ovirt-engine [root@ovirt ~]# What could be wrong? Old created VMs start without problem. In the middle I updated the engine from 4.2.5.2 to 4.2.5.3 and also hypervisor packages, where vdsm has remained at level Aug 03 23:55:09 Updated: vdsm-4.20.35-1.el7.x86_64 In particular: [root@ovirt01 ~]# rpm -qa|grep vdsm vdsm-jsonrpc-4.20.35-1.el7.noarch vdsm-common-4.20.35-1.el7.noarch vdsm-hook-nestedvt-4.20.35-1.el7.noarch vdsm-yajsonrpc-4.20.35-1.el7.noarch vdsm-hook-ethtool-options-4.20.35-1.el7.noarch vdsm-hook-vhostmd-4.20.35-1.el7.noarch vdsm-hook-vmfex-dev-4.20.35-1.el7.noarch vdsm-client-4.20.35-1.el7.noarch vdsm-4.20.35-1.el7.x86_64 vdsm-hook-vfio-mdev-4.20.35-1.el7.noarch vdsm-api-4.20.35-1.el7.noarch vdsm-hook-fcoe-4.20.35-1.el7.noarch vdsm-network-4.20.35-1.el7.x86_64 vdsm-hook-openstacknet-4.20.35-1.el7.noarch vdsm-python-4.20.35-1.el7.noarch vdsm-http-4.20.35-1.el7.noarch [root@ovirt01 ~]# The error on hypervisor: 2018-08-21 15:21:28,760+0200 ERROR (vm/eaaee084) [virt.vm] (vmId='eaaee084-1949-4aae-85c2-6bf46fce7cef') The vm start process failed (vm:94 2) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 871, in _startUnderlyingVm self._run() File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2864, in _run self._buildDomainXML(), File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2253, in _buildDomainXML dom, self.id, self._custom['custom']) File "/usr/lib/python2.7/site-packages/vdsm/virt/domxml_preprocess.py", line 240, in replace_device_xml_with_hooks_xml dev_custom) File "/usr/lib/python2.7/site-packages/vdsm/common/hooks.py", line 136, in before_device_create params=customProperties) File "/usr/lib/python2.7/site-packages/vdsm/common/hooks.py", line 122, in _runHooksDir raise exception.HookError(err) HookError: Hook Error: ('',) 2018-08-21 15:21:28,760+0200 INFO (vm/eaaee084) [virt.vm] (vmId='eaaee084-1949-4aae-85c2-6bf46fce7cef') Changed state to Down: Hook Error: ('',) (code=1) (vm:1682) I found this, but it doesn't seem related: https://bugzilla.redhat.com/show_bug.cgi?id=1518703 Thanks in advance for any hint, Gianluca

Hosted Engine setup issues
by Jeremy Tourville 21 Aug '18

21 Aug '18

If I try to setup hosted engine with the option to use Ansible it eventually fails on me. See https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LPK7OGFALSQFAN… However if I run hosted-engine --deploy --noansible the setup does complete. There is further trouble though, it seems the networks are not being configured properly. If I browse to Compute>Hosts>Hostname and click on the Setup Host Networks button I am presented with a new window that contains an unassigned logical network of "oivrtmgmt" On the left side pane there are two columns for Interfaces and Assigned Logical Networks. Both of those columns are completely empty. I think if I understand correctly the interfaces column should at least have some info in it. [cid:bb1f29b4-888c-410a-9b47-7589f866539a] So my best guess is that for some unknown reason (at least to me) the Engine doesn't '"know how to get setup properly" either with or without Ansible. That's about as well as I can describe it. I hope it makes sense.... Anyone have ideas on what is going wrong here? Thanksfor any troubleshooting advice you can provide!

IPTables firewall to firewalld
by p.staniforth＠leedsbeckett.ac.uk 21 Aug '18

Hello, I get the following messages. "Cluster Default uses IPTables firewall, which has been deprecated in 4.2 of the engine, and will no longer be supported starting with version 4.3. Make sure to switch to Firewalld before upgrading to 4.3." If the correct way to change to firewalld edit cluster, and run reinstall? Thanks, Paul S.

after upgrade from 4.2.3 to 4.2.5, problems with consoles + cockpit
by Jason Keltz 20 Aug '18

20 Aug '18

Hi.. After an upgrade from 4.2.3 to 4.2.5 last week, I notice that I have a console + cockpit problem. Immediately following the upgrade, everything seemed to be working fine. However, today, a couple of days after the upgrade, when I try to view any CentOS VM console, virt-viewer starts, and I see "Connected to graphic server", but there's no console output. This happens on all Linux VMs, though on my two windows VMs, the console still works. If I restart a Linux VM, I get the console back again, but what made me lose access to all the consoles? In addition, if I right click on one of my 4 hosts, and choose "Host Console", it connects to cockpit which reports: "No VM is running or defined on this host" even though there are plenty. I brought one host into maintenance mode, and rebooted it. I then started a few VMs there, and cockpit still doesn't show anything running. All of the hosts have all available ovirt updates, and are running the latest CentOS 7 kernel + O/S updates. Any ideas? There is no issue with firewall. Jason.

info about changing engine ip mode from dhcp to static
by Gianluca Cecchi 17 Aug '18

17 Aug '18

Hello, a colleague of mine installed oVirt engine 4.2.5 on a test CentOS 7.5 system and in its initial configuration he configured its ip via dhcp (using static ip assignment configured at dhcp server side). Now he would like to maintain the same ip/hostname for the engine but with a static configuration on the server. Any hint about how to achieve this? Thanks in advance, Gianluca

Poor performance of oVirt Export Domain
by Aleksey.I.Maksimov＠yandex.ru 17 Aug '18

17 Aug '18

Hello I deployed a dedicated server (fs05.holding.com) on CentOS 7.5 and created a VDO volume on it. The local write test in the VDO volume on this server gives us an acceptable result # dd if=/dev/zero of=/mnt/vdo-vd1/nfs/testfile count=1000000 1000000+0 records in 1000000+0 records out 512000000 bytes (512 MB) copied, 6.26545 s, 81.7 MB/s The disk capacity of the VDO volume is connected to the oVirt 4.2.5 cluster as the Export Domain via NFS. I'm seeing a problem with the low performance of Export Domain. Snapshots of virtual machines are copied very slowly to the Export Domain, approximately 6-8 MB/s. At the same time, if I try to run a write test in an mounted NFS-directory on any of the oVit cluster hosts, I get about 50-70 MB/s. # dd if=/dev/zero of=/rhev/data-center/mnt/fs05.holding.com:_mnt_vdo-vd1_nfs_ovirt-vm-backup/testfile count=10000000 10000000+0 records in 10000000+0 records out 5120000000 bytes (5.1 GB) copied, 69.5506 s, 73.6 MB/s Help me understand the reason for the slow copying to Export Domain on oVirt.

oVirt 4.2.5 : VM snapshot creation does not work : command HSMGetAllTasksStatusesVDS failed: Could not acquire resource
by Aleksey Maksimov 17 Aug '18

Hello We use oVirt 4.2.5.2-1.el7 (Hosted engine / 4 hosts in cluster / about twenty virtual machines) Virtual machine disks are located on the Data Domain from FC SAN.

Clarifications regarding ovirt-provider-ovn network
by Anurag Porripireddi 17 Aug '18

17 Aug '18

Hi, I had some questions a overt-provider-ovn based external network which is built on top of an physical network. I notice that VLAN tagging gets greyed out when I try to create an external provider network. Is it not supported by overt right now?I am on version 4.2.5.3. Also, if I create NICs with the external provider network built atop a physical network on VMs that are on different hosts, but the same cluster, I see they are unable to ping each other, though it seems to work fine if they are on the same host. Is that elected behaviour? Could you you please help me understand why? Thanks, Anurag

Issue with NFS and Storage domain setup
by Inquirer Guy 16 Aug '18

16 Aug '18

Hi Ovirt, I successfully installed both ovirt-engine(ENGINE01) and ovirt node(NODE01) on a separate machines. I also created a FreeNAS(NAS01) with NFS share and already connected to my NODE01, all of these server though I haven't setup a DNS server, was manually added hostname on every machines and I can lookup and ping on them without a problem, I was able to add the NODE01 to my ENGINE01 as well. My issue was when I tried creating a storage domain on my ENGINE01, I did the below steps before running the engine-setup while also following the guide on the ovirt url: https://www.ovirt.org/documentation/how-to/troubleshooting/troubleshooting-… #touch /etc/exports #systemctl start rpcbind nfs-server #systemctl enable rpcbind nfs-server #engine-setup #mkdir /var/lib/exports/data #chown vdsm:kvm /var/lib/exports/data I added the 2 just in case but I have tried each alone but all fails #vi /etc/exports /var/lib/exports/data *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36) /var/lib/exports/data 0.0.0.0/0.0.0.0(rw) #systemctl restart rpc-statd nfs-server Once I started to add my storage domain I get the below error Attached is the engine log for your reference. Hope you guys can help me with these, Im really interested with this great product. Thanks!

Hi Everyone, I am encountering an issue on my oVirt 4.2 self-hosted engine installation. Suddenly the "Preview" button in snapshots menu became inactive, I just cannot revert any previews snapshots. This feature worked fine over the last month, but now it seems to be just inactive. Any thoughts on this ? Thank you very much ! Leo -- Best regards, Leo David

Patches for L1FT?
by Eduardo Mayoral 16 Aug '18

16 Aug '18

Hi, For mitigation of the recently announced L1TF vulnerability, is it sufficient to update the compute nodes to the updated kernel? Are any other updates to KVM / vdsm / ovirt-engine required? Also, for the concurrent variant. Should we disable hyperthreading altogether? Is there any remediation (even if expensive from a performance view), that can be enabled? Thanks for your help! -- Eduardo Mayoral.

Do I need to set VM vnic profile for GlusterFS network?
by Jayme 16 Aug '18

16 Aug '18

I followed this guide to get my three node HCI cluster up and running: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluste… The docs were a bit out of date but most things matched up. I have configured an internal GlusterFS network on a separate subnet on 10Gbe switch and have set it as the glusterFS and migration network. Is this all that is needed to be done for all glusterFS traffic to pass through that network or must the glusterFS vnic profile also be selected for each VM? I'm not sure if my VMs should be using ovirtmgmnt vnic or GlusterFS vnic.

storage domain sync problem and fail to run vm after change LUN mapping
by dvotrak 15 Aug '18

15 Aug '18

Environment: Ovirt version: 4.2.5 Centos 7.5 During a planned maintenance window, multipath configuration was changed according to the storage vendor guidelines. The new configuration modify user_friendly_names from no to yes, so the multipath -ll output changed from this "360060160a6213400fa2d31acbbfce511 dm-8 DGC" to this: "mpathh (360060160a6213400fa2d31acbbfce511) dm-8 DGC". After this change, the following errors are displayed: 1) when attempting to start a VM with direct LUN: Failed to run VM <VMNAME> on Host <HYPERVISOR> VM <VMNAME> is down. Exit message: Bad volume specification <LUN_ID> Inspecting the VM disk, the lun id remains the previous one (360060160a6213400fa2d31acbbfce511) insted of the new one (mpathh) Remove/detach and re-add/re-attach the disk to VM doesen't help. 2) randomly: Storage domains with IDs [<ID>] could not be synchronized. To synchronize them, please move them to maintenance and then activate. Moving it to maintenance and then activate it doesen't help. Inspecting storage domain luns, almost all change the lun id to the new ones (mpathXX), but this one remain in "the old style" (maybe because lun_id is a primary key and this one was already taken?) Any idea on how to resolve these problems? Thanks Sent with [ProtonMail](https://protonmail.com) Secure Email.
