[ovirt-users] ??: bond mode balance-alb

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.

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?

Thanks in advance,
Cong
