NAT+IP masquerading with oVirt 4.2
by julius.schwartzenberg＠gmail.com 27 Jun '18

27 Jun '18

Hi, I'm trying to set up NAT+IP masquerading with oVirt 4.2. I have enabled the libvirt default network on virbr0 and added a network with the same name in oVirt. I have also installed vdsm-hook-extnet and set extnet to 'default' for this network to default. When I try to start my VM with this network assigned to it, I get this error: The host ovirthost did not satisfy internal filter Network because network(s) virbr0 are missing. What should I do to solve this? Best regards, Julius

RHEL5 guests frequently hang when migrating host.
by Eduardo Mayoral 27 Jun '18

27 Jun '18

Hi, I am experiencing that my RHEL5 guests frequently "hang" when migrating host. Console is blank, CPU after migration is 100% and as far as oVirt is concerned, the VM is OK. oVirt is 4.2.3.8-1.el7, on CentOS 7. Hosts are CentOS 7 as well. Cluster is in "Intel Westmere family" CPU type. Guest is RHEL5, fully patched, kernel 4.2.3.8-1.el7 with ovirt-guest-agent installed from EPEL. I do not see anything out of place in the ovirt-engine and vdsm logs, and the guest logs are simply not there, the stop right before the migration,as if the machine had "frozen". Powering the VM off and starting it starts the VM correctly. This does not happen 100% of the time. If I try to migrate the VM when it is freshly started the migration is faster (maybe 5 seconds), and the guest OS does not hang. Anybody else experiencing something similar? Maybe something (timeouts?) that I should tune on the guest OS for RHEL5? Thanks! -- Eduardo Mayoral.

Failed to delete snapshot '<UNKNOWN>' for VM 'vmname'.
by nicolas＠devels.es 26 Jun '18

26 Jun '18

Hi, We're running oVirt 4.1.9, recently we had an issue with snapshots so we had to fix them manually. The issue is mostly solved but now we're seeing a lot of events like this one: 2018-06-25 07:58:06,637+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler6) [91430fc5-284d-4c26-8d8d-b7bf4053a7e4] EVENT_ID: USER_REMOVE_SNAPSHOT_FINISHED_FAILURE(357), Correlation ID: 91430fc5-284d-4c26-8d8d-b7bf4053a7e4, Job ID: da8120a4-9c6d-4379-ad67-a3808db1fd46, Call Stack: null, Custom ID: null, Custom Event ID: -1, Message: Failed to delete snapshot '<UNKNOWN>' for VM 'vmname'. Which generates the following event in the manager: Failed to delete snapshot '<UNKNOWN>' for VM 'vmname'. This event is being generated every 10 seconds, so it's kind of annoying. Any way to remove it manually? It doesn't matter if it entails touching the DB directly. Thanks.

I cannot get the screen on HE to change short of ctl-alt-del which will reboot the HE. I do have backups for the HE that are/were run on a nightly basis. If the cluster was left alone, the HE vm would bounce from machine to machine trying to boot. This is why the cluster is in maintenance mode. One of the nodes was down for a period of time and brought back, sometime through the night, which is when the automated backup kicks, the HE started bouncing around. Got nearly 1000 emails. This seems to be the same error (but may not be the same cause) as listed here: https://bugzilla.redhat.com/show_bug.cgi?id=1569827 Thanks, Hanson

unable to create iSCSI storage domain
by Bernhard Dick 25 Jun '18

25 Jun '18

Hi, I've a problem creating an iSCSI storage domain. My hosts are running the current ovirt 4.2 engine-ng version. I can detect and login to the iSCSI targets, but I cannot see any LUNs (on the LUNs > Targets page). That happens with our storage and with a linux based iSCSI target which I created for testing purposes. When I logon to the ovirt hosts I see that they are connected with the target LUNs (dmesg is telling that there are iscsi devices being found and they are getting assigned to devices in /dev/sdX ). Writing and reading from the devices (also accros hosts) works. Do you have some advice how to troubleshoot this? Regards Bernhard

rhgs 3.3.1 rhev 4.2 vdsm gluster host deploy fails with no real indication of an error, looks like a network error

Hello, Seeing some odd behavior deploying a host to a gluster cluster on rhev 4.2 running rhgs 3.3.1. The host failed to be added to the cluster and there are no real errors in the host deploy logs. Upon further investigation it looks like its failing network host checks. The interfaces gets added to the host when trying to configure host networks, but fails even though everything seems routable. These are the main errors I can see that might be causing an issue. *Jun 24 20:27:12 deadpool.glstr.runlevelone.lan daemonAdapter[17160]: libvirt: Network Driver error : Network not found: no network with matching name 'vdsm-ovirtmgmt'* *Jun 24 20:27:12 deadpool.glstr.runlevelone.lan daemonAdapter[17160]: libvirt: Network Driver error : Network not found: no network with matching name 'vdsm-infiniband'* Fails connectivity check. *Jun 24 20:27:21 deadpool.glstr.runlevelone.lan vdsm[17316]: vdsm vds ERROR connectivity check failed* * Traceback (most recent call last):* * File "/usr/share/vdsm/API.py", line 1650, in _rollback* * yield rollbackCtx* * File "/usr/share/vdsm/API.py", line 1502, in setupNetworks* * supervdsm.getProxy().setupNetworks(networks, bondings, options)* * File "/usr/share/vdsm/supervdsm.py", line 50, in __call__* * return callMethod()* * File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda>* * **kwargs)* * File "<string>", line 2, in setupNetworks* * File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod* * raise convert_to_error(kind, result)* * ConfigNetworkError: (10, 'connectivity check failed')* Fulls logs can be found here, https://paste.fedoraproject.org/paste/9v7DL2uCl2EcRnduliChsQ Any help is appreciated, also let me know if I need to file a bug.

private networking question
by Matthew Wimpelberg 24 Jun '18

24 Jun '18

Hi, I'm currently running oVirt with a self hosted engine configuration on an Intel NUC. All of my VMs are on my home 192.168.1.0/24 network, but I want to set up a completely isolated network like VirtualBox has (https://blogs.oracle.com/scoter/virtualbox-host-only) The NUC that I have only has one NIC so I think I'll have to set up a dummy interface of some kind. I tried that with the below example. I couldn't find a good guide or doc on this. Can someone please assist? [root@host ~]# cat /etc/sysconfig/network-scripts/ifcfg-dummy0 DEVICE=dummy0 BOOTPROTO=none ONBOOT=yes NM_CONTROLLED=no PROMISC=yes 3: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master vnet0 state UNKNOWN group default qlen 1000 link/ether 52:54:00:7e:27:af brd ff:ff:ff:ff:ff:ff inet6 fe80::5054:ff:fe7e:27af/64 scope link valid_lft forever preferred_lft forever Sent with [ProtonMail](https://protonmail.com) Secure Email.

vGPU setup guide
by Callum Smith 24 Jun '18

24 Jun '18

Dear All, IS this the most current and useful example of implenting vGPUs in oVirt? I had understood that 4.2 had NVIDIA GRID support as a flagship feature, but this appears to be 4.1.4? It seems a very reasonable and decent guide, just don't want to go down this route if there's alternatives now available in 4.2.x. https://mpolednik.github.io/2017/09/13/vgpu-in-ovirt/ Regards, Callum -- Callum Smith Research Computing Core Wellcome Trust Centre for Human Genetics University of Oxford e. callum(a)well.ox.ac.uk<mailto:callum@well.ox.ac.uk>

I followed the docs at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ and all works well from the usual web portal. Went to test moVirt and ran into a snag. It wants to download the CA using http://fqdn/ovirt-engine/services/pki-resource?resource=ca-certificate&form…, but that's grabbing the old CA issued by the engine rather than my custom CA. What else needs to be changed? I'm sure I can finagle my way to a fix here by telling moVirt to use a custom URL or file, but this looks like a bug in the docs that would probably best be fixed. -- John Florian

disk performance findings
by william.dossett＠gmail.com 24 Jun '18

I have deployed a HCI environment several times now as I wanted to get some idea of disk performance with Gluster/ On a Dell R720 3 node cluster with H710 PERC controller and 8 x 2TB 7200 RPM SATA drives. My first test was with the 8 drives configured as H/W RAID 6 and I configured Gluster as RAID 6 - quite a lot of redundancy but that was just my first deployment Running IOMeter for 24 hours using all in one access specification I got 240 IOPs. Pretty good for SATA drives. I then broke the RAID and configured 8 virtual disks, one per physical and then deployed Gluster as JBOD - I am not sure how resilient that is, but I assume in a 3 node cluster failures to tolerate would be one. This gave me 267 IOPs. I don't know that much about the internals of Gluster, but when I first asked about this there didn't seem to be much knowledge of what configuration would be best for HCI. I plan to do more research and tests on this, but for what its worth for now, I am going down the JBOD route with no H/W RAID. Regards Bill

Restore and rename engine
by Staniforth, Paul 23 Jun '18

Hello, I have been trying to test our system by restoring from backup to a new machine and running ovirt-engine-rename, then engine-setup. I get to sent back to the main oVirt Web page from any of the portals, which has an Warning triangle saying the engine is initializing. and in the URL it has ovirt-engine/?error_description=server_error%3A+%2Fetc%2Fpki%2Fjava%2Fcacerts+(No+such+file+or+directory)&error=server_error The original machine had a certificate signed by an external authority. I tried putting back the link from apache-ca.pem to ca.pem, the original apache.key.nopass, websocket-proxy.key.nopass as well as hte key files. I upgraded from 4.1.9 to 4.2.3 and it says it is resigning the certificates but still fails. Regards, Paul S.

quick way to start glusterfs managed engine over?
by william.dossett＠gmail.com 23 Jun '18

23 Jun '18

I have successfully got glusterfs playbook to finish once and then my networking was wrong on the managed engine and on the hosts, so I started over. Now I can't seem to even get that far again. I completely reloaded the hosts, but that takes a while. Last time glusterfs failed right at the end with "host is not in 'Peer in Cluster' state" Redeploying fails as partitions already exist. I am deploying to /dev/sdb Is there a quick way to get /dev/sdb back into a state to redeploy to? I think I got there once by doing pvremove and gdisk zap gpt, but not sure if that worked or caused problem on the redeploy. Its very time consuming to start over from scratch, so would appreciate if there is any shortcut instead of reloading the OS. Thans Bill

Hello List 😊 I’m facing an issue regarding Self Hosted Engine appliance deployment on OVirt 4.2( tested on 4.2.2 and 4.2.3). During setup tool, I’m unable to mount a remote storage NFS / iSCSI.
