Hi,
Your guest-vm have to be defined as " Highly Available"
Highly Available
Select this check box if the virtual machine is to be highly available. For example, in cases of host maintenance or failure, the virtual machine is automatically moved to or re-launched on another host. If the host is manually shut down by the system administrator, the virtual machine is not automatically moved to another host.
Note that this option is unavailable if the Migration Options setting in the Hosts tab is set to either Allow manual migration only or No migration . For a virtual machine to be highly available, it must be possible for the Manager to migrate the virtual machine to other available hosts as necessary.
Thanks in advance.
Best regards,
Nikolai

Thanks for detailed explanation. Do you mean only HE VM can be failover? I want to have a try with the VM on any host to check whether VM can be failover to other host automatically like VMware or Xenserver?
I will have a try as you advised and provide the log for your further advice.
Thanks,
Cong

I'd like to add that using of floating MAC "balance-tlb" for mode 5 or ARP negotiation for mode 6 load balancing " balance-alb" will influence latency and performance, using such mode should be avoided.
Mode zero or "balance-rr" should be also avoided as it is the only mode that will allow a single TCP/IP stream to utilize more than one interface, hence will create additional jitter, latency and performance impacts, as frames/packets will be sent and arrive from different interfaces, while preferred is to balance on per flow. Unless in your data center you're not using L2-only based traffic, I really don't see any usage for mode zero.
In Cisco routers the is a functionality called IP-CEF, which is turned on by default and balancing traffic on per TCP/IP flow, instead of per-packet, it is being used for better routing decisions for per-flow load balancing, if turned off, then per-packet load balancing will be enforced, causing high performance impact on router's CPU and memory resources, as decision have to be made on per-packet level, the higher the bit rate, the harder impact on resources of the router will be, especially for small sized packets.
Thanks in advance.
Best regards,
Nikolai

I can only quote jpirko's workds from the link above:
Do not use tlb or alb in bridge, never! It does not work, that's it. The reason
is it mangles source macs in xmit frames and arps. When it is possible, just
use mode 4 (lacp). That should be always possible because all enterprise
switches support that. Generally, for 99% of use cases, you *should* use mode
4. There is no reason to use other modes.

I see that you set local maintenance on host3 that do not have engine vm on it, so it nothing to migrate from this host.
If you set local maintenance on host1, vm must migrate to another host with positive score.

Subject: Re: [ovirt-users] VM failover with ovirt3.5
Hi
I had a try with "hosted-engine --set-maintence --mode=local" on
compute2-1, which is host 3 in my cluster. From the log, it shows
maintence mode is dectected, but migration does not happen.
The logs are as follows. Is there any other config I need to check?

Subject: RE: [ovirt-users] VM failover with ovirt3.5
Thanks for the information. This is the log for my three ovirt nodes.
>From the output of hosted-engine --vm-status, it shows the engine state for
my 2nd and 3rd ovirt node is DOWN.
Is this the reason why VM failover not work in my environment?
No, they looks ok: you can run the engine VM on single host at a time.
How can I make
also engine works for my 2nd and 3rd ovit nodes?
If you put the host 1 in local maintenance mode ( hosted-engine --set-maintenance --mode=local ) the VM should migrate to host 2; if you reactivate host 1 ( hosted-engine --set-maintenance --mode=none ) and put host 2 in local maintenance mode the VM should migrate again.
Can you please try that and post the logs if something is going bad?

Subject: [ovirt-users] VM failover with ovirt3.5
Hi
In my environment, I have 3 ovirt nodes as one cluster. And on top of
host-1, there is one vm to host ovirt engine.
Also I have one external storage for the cluster to use as data domain
of engine and data.
I confirmed live migration works well in my environment.
But it seems very buggy for VM failover if I try to force to shut down
one ovirt node. Sometimes the VM in the node which is shutdown can
migrate to other host, but it take more than several minutes.
Sometimes, it can not migrate at all. Sometimes, only when the host is
back, the VM is beginning to move.
Can you please check or share the logs under /var/log/ovirt-hosted-engine-ha/
?
Is there some documentation to explain how VM failover is working? And
is there some bugs reported related with this?
http://www.ovirt.org/Features/Self_Hosted_Engine#Agent_State_Diagram
Thanks in advance,
Cong

vdsm noipspoof.py vdsm hook problem
by InterNetX - Juergen Gotteswinter
Hi,
i am trying to get the noipspoof.py Hook up and running, which works
fine so far if i only feed it with a single ip. when trying to add 2+,
like described in the ource (comma seperated), the gui tells me that
this isnt expected / nice and wont let me do this.
I already tried modding the Regex, which made the engine to take a
2nd/3rd ip (comma seperated), but it seems that theres somehere else
something wrong with parsing this.
VDSM throws this:
vdsm vm.Vm ERROR vmId=`4c9cb160-2283-4769-a69c-434e6c992c2b`::The vm
start process failed#012Traceback (most recent call last):#012 File
"/usr/share/vdsm/virt/vm.py", line 2266, in _startUnderlyingVm#012
self._run()#012 File "/usr/share/vdsm/virt/vm.py", line 3332, in
_run#012 domxml = hooks.before_vm_start(self._buildCmdLine(),
self.conf)#012 File "/usr/share/vdsm/hooks.py", line 142, in
before_vm_start#012 return _runHooksDir(domxml, 'before_vm_start',
vmconf=vmconf)#012 File "/usr/share/vdsm/hooks.py", line 110, in
_runHooksDir#012 raise HookError()#012HookError
The VM fails to start, engine tries this on every available host (which,
not surprising fail, too).
Anyone any ideas / patches / hints how to mod this hook ?
Thanks

Problem after update ovirt to 3.5
by Juan Jose
Hello everybody,
After upgrade my engine to oVirt 3.5, I have also upgraded one of my hosts
to oVirt 3.5. After that it seems that all have gone good aparently.
But in some seconds my ISO domain is desconnected and it is impossible to
Activate. I'm attaching my engine.log. The below error is showed each time
I try to Activate the ISO domain. Before the upgrade it was working without
problems:

Stucked VM Migration and now only run once
by Kurt Woitschach
This is an OpenPGP/MIME signed message (RFC 4880 and 3156)
--gioR5jNPrlhFWJc7CMfuUMwUJC4shLNV5
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable
Hi all,
we have a Problem with a VM that can only be started in run-once mode.
After a temporary network disconnect on the hosting node, the vm (and
some others) was down. When I tried to start regularly, it showed a
currently beeing migrated status.
I only could start it with run-once.
Reboot didn't make a change.
Any ideas?

Re: [ovirt-users] Can not connect to Storage domain data

I found the workaround for this.
For some reason my Storage domain of data can not be mounted. I just mount =
it manually, like
mount -t nfs nfs2-3:/data /rhev/data-center/mnt/nfs2-3:_data
Actually, the folder of "/rhev/data-center/mnt/nfs2-3:_data" has been creat=
ed. I think this may be some bug as for in my environment, I will reproduce=
it always if I try to deploy the host from second time.
Thanks,
Cong

I think the problems for my issue are related with the NFS version.
>From the second, if I change the value of Defaultver /etc/nfsmount.conf fr=
om "Defaultvres=3D4" to "Defaulvers=3D3", the mount can not be done. When I=
changed it back to "Defaultvers=3D4", it will work.
Also from /proc/mounts, it shows the nfs version is nfs4. But for my first =
host, it is nfs3.
Do somebody have the similar issue about thi?

Hi
I successfully deployed the first ovirt host with hosted-engine -deploy. En=
gine VM works well.
While, when I try to create the second host with the same way as the guide =
of
http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part=
-two/
I am not using GlusterFS, and just use one external storage(nfs) in my envi=
ronment.
The issue I have is in the engine administration menu, it says "can not con=
nect to storage domain data"
In the second host, I checked with nfs-check.py for both storage and data d=
omain. It shows the status is ok.
http://www.ovirt.org/Troubleshooting_NFS_Storage_Issues
During deployment of the second host, how the data domain is trying to be m=
ounted?
Thanks,

Introduction!
by Tom Weeks
Hello,
I am happy to join the community and help support the project. I'm a long
time user of vSphere/vCenter but I am an aspiring to work within
open-source world. My work experience is in corporate environments and
includes virtualization, storage, as well as basic networking.
I hope I can start helping by converting my homelab from the VMware stack
to oVirt. I can contribute by submitting bug requests and
documentation...let me know if that would be helpful!
