oVirt hosted-engine-setup issues with getting host facts
by Mariusz Kozakowski 06 Jun '18

Hello, We've been trying to setup oVirt environment for few days but we have issue with hosted-engine-setup (ansible script). We managed to fix few small things and have them merged upstream but unfortunately right now the installation process fails on getting host facts. It looks like it cannot proceed because it fails when connecting to ovirt-engine API of the bootstrap VM. The oVirt API / webpanel is working, I tested it via a browser and I can login without issues using the admin password chosen earlier in the process. 2018-05-18 15:26:47,800+0200 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:100 TASK [Wait for the host to be up] 2018-05-18 15:39:14,025+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 {u'_ansible_parsed': True, u'_ansible_no_log': False, u'changed': False, u'attempts': 120, u'invocation': {u'module_args': { u'pattern': u'name=host01.redacted', u'fetch_nested': False, u'nested_attributes': []}}, u'ansible_facts': {u'ovirt_hosts': []}} 2018-05-18 15:39:14,127+0200 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:98 fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": []}, "attempts": 120, "changed": false} May 18 13:34:34 host01 python: ansible-ovirt_hosts_facts Invoked with pattern=name=host01.redacted fetch_nested=False nested_attributes=[] auth={'timeout': 0, 'url': 'https://ovirt-dev.redacted/ovirt-engine/api', 'insecure': True, 'kerberos': False, 'compress': True, 'headers': None, 'token': 'R--token-redacted', 'ca_file': None} Do you have idea what/where is issue and how to fix it?

Hi All, I'm getting an error when trying to import an OVA file to my oVirt.

Hi, I have made two scripts to help importing VMs from XenServer to oVirt. https://github.com/akrejcir/ovirt-import-xen-ova Maybe they will be useful to someone. Regards, Andrej

Installing 3rd party watchdogs?
by femi adegoke 06 Jun '18

06 Jun '18

"Important: Third-party watchdogs should not be installed on Red Hat Enterprise Linux hosts". https://www.ovirt.org/documentation/install-guide/chap-Enterprise_Linux_Hos… Does this mean no monitoring agents/packages should be installed?

Debugging ceph access
by Bernhard Dick 06 Jun '18

06 Jun '18

Hi, as you might already know I try to use ceph with openstack in an oVirt test environment. I'm able to create and remove volumes. But if I try to run a VM which contains a ceph volume it is in the "Wait for launch" state for a very long time. Then it gets into "down" state again. The qemu log states 2018-05-25T15:03:41.100401Z qemu-kvm: -drive file=rbd:rbd/volume-3bec499e-d0d0-45ef-86ad-2c187cdb2811:id=cinder:auth_supported=cephx\;none:mon_host=[mon0]\:6789\;[mon1]\:6789,file.password-secret=scsi0-0-0-0-secret0,format=raw,if=none,id=drive-scsi0-0-0-0,serial=3bec499e-d0d0-45ef-86ad-2c187cdb2811,cache=none,werror=stop,rerror=stop,aio=threads: error connecting: Connection timed out 2018-05-25 15:03:41.109+0000: shutting down, reason=failed On the monitor hosts I see traffic with the ceph-mon-port, but not on other ports (the osds for example). In the ceph logs however I don't really see what happens. Do you have some tips how to debug this problem? Regards Bernhard

Cannot see ipaddr of new VM
by 03ce007＠gmail.com 06 Jun '18

I have got a self-hosted-engine (4.2) running on centos (7.4). I am trying to create new vanilla vm with static ip using cloud-init to test ssh connectivity. I have below playbook - - name: Add vanilla vm ovirt_vms: auth: "{{ ovirt_auth }}" name: test01 cluster: Default state: running memory: 2GiB cpu_cores: 8 operating_system: rhel_7x64 high_availability: true high_availability_priority: 50 # Available from Ansible 2.5 cloud_init: nic_boot_protocol: static nic_ip_address: 10.34.60.86 nic_netmask: 255.255.252.0 nic_gateway: 10.34.63.254 nic_name: eth1 nic_on_boot: true host_name: test01.ovirt.dw custom_script: | write_files: - content: | Hello, world! path: /tmp/greeting.txt permissions: '0644' user_name: root root_password: super_password nics: - name: vnet0 network: ovirtmgmt profile: ovirtmgmt interface: virtio # taken from actual vm-infra playbook - name: Add disks ovirt_disks: auth: "{{ ovirt_auth }}" name: "{{ item.0.name }}_{{ item.1.name }}" vm_name: test01 size: "{{ item.1.size | default(omit) }}" format: "{{ item.1.format | default(omit) }}" storage_domain: "{{ item.1.storage_domain | default(omit) }}" interface: "{{ item.1.interface | default(omit) }}" bootable: "{{ item.1.bootable | default(omit) }}" wait: true with_subelements: - "{{ vms }}" - "profile.disks" - flags: skip_missing: true the playbook runs successfully, but when I want to see the summary of vms using ovirt4.py, i do not see any devices attached, nor using curl api i see anything under reported_devices. Is there something I am missing? thank you.

4.2 Error importing VM, No more than one unmanaged USB controller is expected for a VM
by Thomas Wakefield 06 Jun '18

06 Jun '18

Working on migrating from 4.1 to 4.2 on new hardware. Hit a snag importing a VM, and the VM won’t start. * Cannot run VM. No more than one unmanaged USB controller is expected for a VM. [cid:555F4AC2-4498-461D-AAEF-0B1BC5BC7C91@cola.local] Any thoughts on how to remove the extra USB controller? Thanks, Tom

Backup VMs on oVirt 4.2+ with Disk image transfer
by wodel youchi 06 Jun '18

06 Jun '18

Hi, I am testing a product that can interface with oVirt API to backup VMs. The product can use v3 API (for oVirt 3.5.1+) with a proxy VM on oVirt to backup the VMs to the Export domain. And it can use v4 API (for oVirt 4+) to backup VMs, and it offers two methods for that : - for oVirt 4+ it can use Disk attachment mode, this mode uses a proxy VM on oVirt to attach the snapshot of the VM to be backed-up, and then the proxy VM can do the backup of the disk or communicate with an external backup software. This mode offers only full backups (pretty similar to v3). - for oVirt 4.2+ it can use Disk image transfer, this mode does not need a proxy VM, it exports data directly using the oVirt 4.2+ API to the backup server, and uses snapshot-chains provided by the new RHV/oVirt, which make it possible to have incremental VMs backups. I cannot get any documentation about the later approach (Disk image transfer), and my question is : what network does this approach uses to transfer the backup stream, is it ovirtmgmt network since we're talking to the API? My concern is about the bandwidth of this network, especially when backing-up huge and multiple VMs. Regards.

Hi, what is the best choice for a CLI interface vs oVirt 4.2 ? I've looked for it and I saw that ovirt-shell is already deprecated. Thanks Simon

I just have no ping between vms on different hosts when connecting ovn network with subnet to physical network(ovirtmgmt)? I did this thing vdsm-tool ovn-config 172.20.139.27(ip of my engine) 172.20.139.81(ip of host, which storaging vm).
