Re: VM's disk stuck in migrating state
by nicolas＠devels.es
Thanks.
I've been able to see the line in the log, however, the format differs
slightly from yours.
2018-05-17 12:24:44,132+0100 DEBUG (jsonrpc/6) [jsonrpc.JsonRpcServer]

As you can see, there's no path field there.
How should I procceed?

VM interface bonding (LACP)
by Doug Ingham
Hi All,
My hosts have all of their interfaces bonded via LACP to maximise
throughput, however the VMs are still limited to Gbit virtual interfaces.
Is there a way to configure my VMs to take full advantage of the bonded
physical interfaces?
One way might be adding several VIFs to each VM & using ALB bonding,
however I'd rather use LACP if possible...
Cheers,

oVirt 4.1 upgrade hosted-engine
by dlotarev＠yahoo.com
Hi! I have a two nodes (A and B), and running vm HostedEngine on host A.
After upgrade host B to latest release CentOS (7.5.1804), i trying to upgrade host A, but i cannot migrate HostedEngine to host B for next upgrade CentOS. Another VMs migrated to Host B w/o problems.
In logs on host A i have following lines:
May 17 12:58:16 ovirt-h1 libvirtd: 2018-05-17 07:58:16.728+0000: 3637: error : virNetClientProgramDispatchError:177 : internal error: cannot execute command QEMU «cont»: Failed to lock byte 100
May 17 12:58:38 ovirt-h1 journal: ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine ERROR Migration failed: {u'status': {'message': 'Done', 'code': 0}, u'progress': 100}
Please explain me what is my mistake?
P.S I found, that host B have a missmatch in version of packages:
# rpm -aq|grep qemu|sort -n
centos-release-qemu-ev-1.0-2.el7.noarch
ipxe-roms-qemu-20170123-1.git4e85b27.el7_4.1.noarch

qemu-kvm-tools-ev-2.9.0-16.el7_4.14.1.x86_64
Package qemu-kvm-tools-ev has version 2.9.0, while another packages of qemu has 2.10 version.
Thank you so much for response.

hosted-engine deploy not use FQDN
by dhy336＠sina.com
Hi
I deploy hosted-engine by #hosted-engine --deploy, but I do not use FQDN, I want to visit engine directly by ip
besides, I have not DNS server, I want to skip setup Engine VM FQDN， because my project can not to setup /etc/hosts
Please provide the FQDN you would like to use for the engine appliance. Note: This will be the FQDN of the engine VM you are now going to launch, it should not point to the base host or to any other existing machine. Engine VM FQDN: (leave it empty to skip): []:

Self-Hosted engine deploy fails but hosted-engine --vm-status shows engine in good health
by 03ce007＠gmail.com
I am setting up self-hosted engine (4.2) on centos 7.4.
The setup runs all the way through and creates the local VM, but fails on task "Wait for the local bootstrap VM to be down at engine eyes".
But if I then run hosted-engine --vm-start, it comes back up and shows it is in good health, but when I do an api call with curl, it shows me that the host is in 'non responsive' state! I cannot deploy any VM on the engine VM, the ssh connection fails.
How and what could have caused it, where can i find more detailed information related to this error/status of engine vm ?
Thanks

ovirt 4.2 failed deploy
by Alex K
Hi all,
I am trying to setup ovirt 4.2 self hosted with 3 nodes.
I have done several 4.1 installations without issues. Now at 4.2 I get:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unable
to resolve address\n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing
ansible-playbook
I am running:
hosted-engine --deploy --config-append=/root/ovirt/storage.conf
Checking the log doesn't give an easy reference of the issue. Seems to be
related with DNS but I can confirm that the host can resolve the engine
FQDN from /etc/hosts or from the DNS server.
Any ideas?
Thanx,
Alex

ovirt engine frequently rebooting/changing host
by Bernhard Dick
Hi,
currently I'm evaluating oVirt and I have three hosts installed within
nested KVM. They're sharing a gluster environment which has been
configured using the oVirt Node Wizards.
It seems to work quite well, but after some hours I get many status
update mails from the ovirt engine which are either going to EngineStop
or EngeineForceStop. Sometimes the host where the engine runs is
switched. After some of those reboots there is silence for some hours
before it is starting over. Can you tell me where I should look at to
fix that problem?
Regards
