Upgrade guide for oVirt 4.1.x?
by Davide Ferrari 27 Mar '17

27 Mar '17

Hello following the links from the official release notes, I always end up to this page https://www.ovirt.org/documentation/upgrade-guide/upgrade-guide/ which just covers updating from 3.6 to 4.0. Is this still valid for 4.0 -> 4.1 upgrades? Thanks -- Davide Ferrari Senior Systems Engineer

Automatic restart of VM on another host if a host goes down

This is a multi-part message in MIME format. --------------2378525B0912DE68F55F66E1 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, We are now using oVirt 4.1 in our lab with 2 hosts and a separate server for engine. Both hosts (Dell R710 Servers) are in a single cluster and load balancing & migrations work perfectly. However, if a physical server goes down, the VMs running on that server, gets paused ans status goes changes to "?". They do not move or restart on the another host automatically. We have to manually intervene, stop the VMs, restart them on another server. Is there a way in which this migration can be automated? -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required.

Hi Guys, I have upgraded from 4.0.6 to 4.1.1 and I see now that my storage is now shown in the overview tab when you do Datacenter>Storage, but they are shown under the Storage Tab of the domain.

installing a new host when engine in 4.1 and 4.1.1 just released
by Gianluca Cecchi 25 Mar '17

25 Mar '17

Hello, suppose current situation with 4.1.1 just released: - my environment is in 4.1 with an engine a DC/Cluster with some hosts - I configure a new DC/Cluster/Host connected to the same engine - when I add the 4.1 repo for the host and install host from the engine, the picked up packages are indeed 4.1.1, while my engine is still 4.1 Does this constitute a problem? If this is the case, how to install a 4.1 (not 4.1.1) host if I have still engine in 4.1 and I have not intention to upgrade right now? On this new host I got for example ovirt-release41-4.1.1-1.el7.centos.noarch vdsm-4.19.10-1.el7.centos.x86_64 while on my current hosts I have ovirt-release41-4.1.0-1.el7.centos.noarch vdsm-4.19.4-1.el7.centos.x86_64 Thanks, Gianluca

iSCSI Discovery cannot detetect LUN
by Lukáš Kaplan 24 Mar '17

24 Mar '17

Hello all, please do you have some experience with troubleshooting adding of iSCSI domain to ovirt 4.1.1? I am chalenging this issue now: 1) I have successfuly installed oVirt 4.1.1 environment with self-hosted engine, 3 nodes and 3 storages (iSCSI Master domain, iSCSI for hosted engine and NFS ISO domain). Everything is working now. 2) But, when I want to add new iSCSI domain, I can discover it, I can login, but I cant see any LUN on that storage. (I had same problem in oVirt 4.1.0, so I made upgrade to 4.1.1) 3) Then I tryed to add this storage to another oVirt environment (oVirt 3.6) and there are no problem. I can see LUN on that storage and I can connect it to oVirt. I tryed to examine vdsm.log, but it is very detailed and unredable for me :-/ Thak you in advance, have a nice day, -- Lukas Kaplan

Libvirtd Segfault
by Aaron West 24 Mar '17

24 Mar '17

Hi Guys, I've been having some issues this week with my oVirt 4.1 install on CentOS 7... It was previously working great but I made a couple of alterations(which I've mostly backed out now) and I ran a yum update followed by a reboot, however. after it came back up I couldn't start any virtual machines... The oVirt web interface reports : VDSM Local command SpmStatusVDS failed: Heartbeat exceeded VDSM Local command GetStatsVDS failed: Heartbeat exceeded VM My_Workstation is down with error. Exit message: Failed to find the libvirt domain. Plus some other errors so I checked my "dmesg" output and libvirtd seems to segfault : [70835.914607] libvirtd[10091]: segfault at 0 ip 00007f681c7e7721 sp 00007f680c7d2740 error 4 in libvirt.so.0.2000.0[7f681c73a000+353000] Next I checked logs but I couldn't find anything that seemed relevant to me, I mean I see lots of oVirt complaining but that makes sense if libvirtd segfaults right? So last ditch effort was try and use strace and hope with my limited knowlege I spot something uselful but I didn't so I've attahced the strace output to this email in the hope someone else might.

Upgrade from 3.6 to 4.1
by Brett Holcomb 24 Mar '17

24 Mar '17

I am currently running oVirt 3.6 on a physical server using hosted engine environment. I have one server since it's a lab setup. The storage is on a Synology 3615xs iSCSI LUN so that's where the vms are. I plan to upgrade to 4.1 and need to check to make sure I understand the procedure. I've read the oVirt 4.1 Release Notes and they leave some questions. First they say I can simply install the 4.1 release repo update all the ovirt-*-setup* and then run engine-setup. 1. I assume this is on the engine VM running on the host physical box. 2. What does engine-setup do. Does it know what I have and simply update or do I have to go through setup again. 3. Then do I go to the host and update all the ovirt stuff? However, they then say for oVirt Hosted Engine follow a link for upgrading which takes me to a Not Found :( page but did have a link back to the release notes which link to the Not Found which.... So what do I need to know about upgrading a hosted engine setup that there are no directions for. Are there some gotchas? I thought that the release notes said I just had to upgrade the engine and then the host. Given that my VMs are on iSCSI what happens if things go bad and I have to start from scratch. Can I import the VMs created under 3.6 into 4.1 or do I have to do something else like copy them somewhere for backup. Any other hints and tips are appreciated. Thanks.

You can use oVirt 4.1 with the ovirt-engine-sdk-python package version 3.x, they are backwards compatible. Regards.

[Python SDK] Setup Host network with IP address
by TranceWorldLogic . 23 Mar '17

23 Mar '17

Hi, I am trying to setup network via python sdk as shown below: myhost_service.setup_networks( modified_network_attachments = [ types.NetworkAttachment( host = myhost, host_nic = types.HostNic(name="eth0"), network = types.Network(name="Hello"), ip_address_assignments = [ types.IpAddressAssignment( assignment_method = types.BootProtocol.STATIC, ip = types.Ip( address="192.168.300.10", netmask="255.255.255.0", version=types.IpVersion.V4, ), ) ], ), ] ) But I am getting below error: "ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Bad format of IPv4 address]". HTTP response code is 400." Please help me. Ovirt release version = 4.0 Thanks, ~Rohit

ovirt Node Building
by shubham dubey 23 Mar '17

23 Mar '17

Hello, I have recently build ovirt-engine from source using this link( http://www.ovirt.org/develop/developer-guide/engine/engine-development-envi…) Now I want to build ovirt node using this( http://www.ovirt.org/develop/projects/node/building/) I am confused that can I build that node on the same system as of ovirt-engine or I need to do these steps on any other system. Thanks, Shubham

strange behavior of ovirt-node ng update
by Sergey Kulikov 23 Mar '17

23 Mar '17

I have one Ovirt Node in my test cluster(others are centos), I'm observing strange behavior of update checker in engine. In options I can see: engine=# select * from vdc_options where option_name='OvirtNodePackageNamesForCheckUpdate'; option_id | option_name | option_value | version -----------+-------------------------------------+----------------------------+--------- 124 | OvirtNodePackageNamesForCheckUpdate | ovirt-node-ng-image-update | general (1 row) so it tries to check for updated version of ovirt-node-ng-image-update, but there is no ovirt-node-ng-image-update package installed inside updated node image, so engine always shows available updates on this node to the same version: > Check for available updates on host XXX was completed successfully with message 'found updates for packages ovirt-node-ng-image-4.1.1-1.el7.centos, ovirt-node-ng-image-update-4.1.1-1.el7.centos'. I saw a bug in bugzilla, that it should be fixed in 4.0 Initially engine was set up as 4.x version, after that updated between releases and finally to 4.1.0, and today to 4.1.1. I saw this behavior on 4.1.0 node and also on 4.1.1, on this page: http://www.ovirt.org/node/4.0/update/ Maybe my OvirtNodePackageNamesForCheckUpdate was changed between releases, but engine-setup left it untouched and i should change it manually? If so, what it should look like? --

VMs changing to unknown state
by Michael Watters 23 Mar '17

23 Mar '17

I have an ovirt host running ovirt 4.0 which keeps putting the VMs running on that host into an unknown state. I checked the vdsm logs and there are several errors similar to below. Mar 20 10:16:11 ovirt-node-production3.example.com vdsm[17123]: vdsm root ERROR Unhandled exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 372, in wrapper return f(*a, **kw) File "/usr/share/vdsm/virt/migration.py", line 624, in run self.monitor_migration() File "/usr/share/vdsm/virt/migration.py", line 657, in monitor_migration job_stats = self._vm._dom.jobStats() File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 69, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 123, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 917, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1387, in jobStats if ret is None: raise libvirtError ('virDomainGetJobStats() failed', dom=self) libvirtError: Requested operation is not valid: domain is not running Restarting vdsmd resolves the issue however I would like to resolve the issue permanently. Does anybody know what would cause this?

NFS ISO domain from hosted-engine VM
by Devin A. Bougie 23 Mar '17

23 Mar '17

Hi, All. Are there any recommendations or best practices WRT whether or not to host an NFS ISO domain from the hosted-engine VM (running the oVirt Engine Appliance)? We have a hosted-engine 4.1.1 cluster up and running, and now just have to decide where to serve the NFS ISO domain from. Many thanks, Devin

hosted-engine with iscsi storage domain
by Devin A. Bougie 23 Mar '17

23 Mar '17

We have a hosted-engine running on 4.1 with an iSCSI hosted_storage domain, and are able to import the domain. However, we cannot attache the domain to the data center. Just to make sure I'm not missing something basic, does the engine VM need to be able to connect to the iSCSI target itself? In other words, does the iSCSI traffic need to go over the ovirtmgmt bridged network? Currently we have the iSCSI SAN on a separate subnet from ovirtmgmt, so the hosted-engine VM can't directly see the iSCSI storage. Thanks, Devin

Python-SDK: ovirtsdk4.Connection object autologout?
by nicolas＠devels.es 23 Mar '17

23 Mar '17

Hi, We've recently upgraded from oVirt 4.0.x to 4.1.0 and it seems that the behavior of a script we wrote in Python-SDK has changed slightly. We have a script that needs to be executed forever (daemon mode). This daemon creates an ovirtsdk4.Connection object and uses the same Connection object all the time. conn = sdk.Connection( url=URI, username=USERNAME, password=PASSWORD, ca_file=CAFILE ) Between iterations we have ~5 minutes delays which we accomplish with a time.sleep(...) call. After some of these iterations (5 or 6), when trying to perform an operation on the Connection object (in this case, listing all SDs): try: sys_serv = conn.system_service() sd_serv = sys_serv.storage_domains_service() storages = sd_serv.list(search=sd_search_query) except Error, e: log('ERR: Error getting storage domains: %s' % (e)) We start getting exceptions (i.e., the sd_serv.list() call throwing an Error exception) with this message: ERR: Error getting storage domains: HTTP response code is 401. I believe this has something to do with the Connection object expiring (even if it's not idle more than 5 minutes at any time). Is there a way to "refresh" the Connection object so it doesn't auto-logout (assuming this is the actual problem)? As I said, this started happening as of oVirt 4.1.0. ovirt-engine-sdk-python version is 4.1.1. Any ideas? Thanks.
