Hi
If we deploy Keystone using memcached as token backend we see that bringing
down 1 of 3 memcache servers results in some tokens getting invalidated. Does
memcached not support replication of tokens
So if we wanted HA w.r.t keystone tokens should we use SQL backend for tokens?

I am getting this error when i try to verify network settings with Fuel 7.0
2015-12-17 20:49:36ERR[566] Error running RPC method verify_networks:

Which tunnel? I have VM running on HOST with bridge networking, its
vnet pair. I don't have any tunnel.
I increase only txqueuelen 500 to txqueuelen 1 which improve
networking little bit

Was that the VM or the hypervisor ?
These tips are good to include the upcoming hypervisor tuning guide

Thanks for response,
Yes if i ping from remote machine to that VM i am getting timeout at
some interval.
My application is CPU intensive, it is not doing any disk operation,
actually this application is base on VoIP. so pure RTP traffic flowing
on network. small UDP packets.

Just to clarify, when you say "getting ping breaks" you mean that is
when you start seeing pings not getting responses yes?

I think i found solution, it improve little bit performance
on tapdd55b834-f8 interface default txqueuelen size was 500, I have
changed it to 1

We have our own custom application running on guest VM. i am just
checking performance of VM. but i found if load go little up machine
start breaking ping.
I didn't run iperf test yet. which i am going to run in a min.

I just ran iperf and here is the results, bi-directional

[ 5] 0.0-10.0 sec 1.04 GBytes 895 Mbits/sec
[ 4] 0.0-10.0 sec 1.09 GBytes 935 Mbits/sec
Look like when guest is under load, it can't handle traffic and start
dropping packets.
On Thu,
Okay Satish ,
Im not expert and do not want to divert you wrong direction.
I want to make your test on my server to cross check , can you pls explain
how and with what tool and to where you are making this test.
Regards

Thanks for reply,
Following is my guest xml file.
I am using Openstack JUNO and it use OVS.
Following is TOP command on guest machine, at this point i am getting
ping breaks
top - 16:10:30 up 20:46, 1 user, load average: 4.63, 4.41, 3.60

Hello ,
Cool ! Todays I am testing to but not such way just only KVM.
Wonder 2/3 things ;
1) Are you using virtio?
Hi,
Have tried to tweak your network performance?
Is it fast forwarding enable?
You can try to test your network performance using iperf before run your
application.
Best regards,

I am doing some testing on Openstack VM network performance. following
i am doing
Comute node: 8 CPU / 32GB mem
VM instance: 8vCPU / 8GB mem
when i am running heavy load application, immediate my ping started
breaking for VM.. but at same time if i ping Compute Host, its working
fine without any
19 matches
