can't import vm from KVM host
by Nelson Lameiras 28 Nov '16

28 Nov '16

Hello, I'm trying to import virtual machines from a KVM host (centos 7.2) to an oVirt 4.0.2 Cluster using the "import" feature on GUI. If the original VM is using RAW/QCOW2 files as storage, everything works fine. But if the original VM is using a special block special device as storage (like a LVM or SAN volume), it's simply not recognized. The VM does appear in the import list of the KVM host, but it's disk count is 0! Is this a known technical obstacle or am I doing something wrong ? below is the storage part of the xml describing the original VM : <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/mapper/vg_01-lv_sys'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/sdc'/> <target dev='vdb' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </disk> We have hundreds of virtual machines in production with this type of configuration... How can we migrate them safely to oVirt? thanks Nelson

How to update ovirt on a single-host hosted-engine host
by Derek Atkins 28 Nov '16

28 Nov '16

Hi, I've got ovirt running on a single host (with hosted-engine). I just upgraded the engine from 4.0.4 to 4.0.5. That was pretty easy; I just put the system into global maintenance mode, then yum update, then engine-setup, then took the host out of maint mode. Easy peasy. Now, I want to update the host itself. Since it's a single host system I know I'll need to shut down all the VMs (because there's no place to migrate them). This means I'll need to shut down the engine VM, too. That would imply that I can't use the "Update" feature from the ui, right? So what IS the process to properly update a single-host host? My guess is: * shutdown all the VMs * go into global maint mode (what IS the difference between global and local?) * shutdown the engine/engine VM * yum update on the host * restart services (or reboot, I guess) * bring the system out of maintenance mode Am I missing a step? Do I need to run hosted-engine --deploy again similar to how I needed to run "engine-setup" on the engine? Or is there something else I need to run? Thanks, -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

kdump integration warnings
by Michael Watters 28 Nov '16

28 Nov '16

I have two brand new ovirt hosts running ovirt 3.6 which are giving a warning message whenever the host is activated. >Kdump integration is enabled for host ovirt-node-production1, but kdump is not configured properly on host. The server does have the kdump package installed and the service is running according to systemctl. Do I need to update the /etc/kdump.conf file to work properly or does ovirt do that on its own?

Ansible Modules for ovirt

--_000_A266EE4C473A0B4687CFED336548C94101410CE14BLDNEX21Gamesy_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I have been trying to use the following ansible modules (based on the last = devel commit in the ansible github repo for the extras modules 43bb97bc3763= b0335e245606eb2985314902cc91): * ovirt_vms * ovirt_disks I have had varying degrees of success, and I would like to list the followi= ng issues: * Through the REST API, I can define multiple nic card configuratio= ns for cloud-init, however only 1 can be done with Ansible. Also, when usin= g templates, it automatically assumes I will be using the last version of t= he template, this had to be defined when using REST. * Assume I have deployed from a template. This will create a VM wit= h a disk that is already attached. Now, let's say I want to confirm, or add= more disks to the VM. If I pass a number of disks, that have already been = attached, and I reference them by name (in ovirt_disks), I get an error. If= I do the same operation by ID it seems to work. However I cannot get the I= D when running ansible, I need to get it from REST. When I query ovirt_vms,= disk attachments comes up as o "disk_attachments": [], If that field gets populated, I could then in turn run ovirt_disks with the= ID, after querying the VM to get the attachments, but as it is it cannot b= e done. I'll give an example - name: Get Disks ovirt_disks: auth: "{{ovirt_auth}}" vm_name: "{{item.0.name}}" name: "{{item.1.name}}" interface: "{{item.1.interface}}" register: r_disks with_subelements: - "{{virtual_machines }}" - drives If the drives have already been attached this will fail... = but - name: Add Disks to VMs ovirt_disks: auth: "{{ovirt_auth}}" vm_name: "{{item.0.name}}" id: 8fc2811e-7774-4903-a5b3-489fdedb377b size: "100GiB" format: "{{item.1.format}}" storage_domain: "{{item.1.storage_domain.name}}" bootable: "{{item.1.bootable}}" interface: "{{item.1.interface}}" state: attached with_subelements: - "{{virtual_machines }}" - drives The second example is working, even if the disk has already= been attached. I'm assuming that since I'm creating the VM from a template, there might be= multiple disks with the same name, and the wrong ID is being retrieved.

Re: [ovirt-users] Users Digest, Vol 62, Issue 192
by Joost＠familiealbers.nl 28 Nov '16

28 Nov '16

Darrel, i tend to agree with you. One of the reasons for choosing ovirt over i.e vmware is fact you will benefit from the flexibility of linux in general. Besides the fact its actually quite good and open source offcourse. The fact ovirt stops accepting custom net setups is not the best feature perhaps for most. At least not for me. Either way using the bond approach i am at least able to crack on. I know there is a lot one can tailor by defining config options in /etc/ovirt-host-deploy however it feels like its one of the more undocumented features. I tried a number of things but ended up with errors i had scavenge my way through. I am happy for now. Ill keep my eye out on the list to see if this particular issue will be taken up in the future.

ovirtmgmt manual bridge cannot be used in ovirt 4.0
by joost＠familiealbers.nl 28 Nov '16

28 Nov '16

Hi All, In our ovirt 3.5 setup. i have always setup the ovirtmgmt bridge manually . The bridge consisted of 2 nic's I'd have /etc/vdsm/vdsm.conf list net_persist = ifcfg When i then deployed the host from the ovirt ui or api it would install and would display the network setup correctly in the ui. On ovirt 4. (vdsm-4.18.15.3-1.el7.centos.x86_64) I seem unable to follow the same approach. In the engine logs i get among other things 'If the interface ovirtmgmt is a bridge, it should be torn-down manually. ' the interface is indeed a bridge with two nics which i would like to keep this way. On the host vdsm.log i get limited info, when start a python terminal to obtain netinfo i get this >>> from vdsm.tool import unified_persistence >>> unified_persistence.netswitch.netinfo() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch.py", line 298, in netinfo _netinfo = netinfo_get(compatibility=compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 109, in get return _get(vdsmnets) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 101, in _get report_network_qos(networking) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/qos.py", line 46, in report_network_qos iface, = host_ports ValueError: too many values to unpack As it appears the line in question does not like to deal with a list of nics i think. but either way. Is in ovirt 4 the ability to use the ovirtmgmt bridge with multiple nics removed? If so what can i do to stick to what we have done in the past. Thanks.
