Here is the config -

2017-05-18 13:05:18 -0500 asked a question How to increase default timeout value of LB ?

I am seeing that the default timeout comes out to be 50000ms, for server and the client .. I am using HAPROXY , and below is how my config for LBAAS looks -

I am using Juno .. I have been searching this a bit, and my app team is complaining about, a large query, where this timeout is not sufficient ..

I am in this situation, and my VM is performing at half the BW than hypervisor host .. I am @ juno

i am using RPCTEST to test the things out

https://community.mapr.com/thread/8693

i can update on dumpxml of the VM if needed .. I checked web for network tuning or how Can I be able to match BW with physical ..

How did you deal with above situation ?

well sorry, what i called this f67f5a16cc3a46c7b9004cee05233642 is actually a tenant id, so it is not an endpoint, my bad. But still i am puzzled about resource not found error and instance shows as scheduling, not just this tenant, but any

2014-05-03 10:00:09 -0500 asked a question HTTP exception thrown: The resource could not be found

I modified endpoints, and corrected. I had some bad setup and things were not showing right, so had to add some endpoints back correctly. In this process, looks like something went wrong. Nova no more works to deploy instances, it just shows scheduling as status. I turned verbose on, and found below - Any idea why resource not found error ? i dont see any endpoint with id "f67f5a16cc3a46c7b9004cee05233642" +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

2014-04-17 15:59:50 -0500 asked a question vm migration from esxi to kvm

Hi I am using virt v2v tool provided by redhat, and i am able to convert VM and migrate over to openstack. Further challenge i see is, "nova list --all-tenants" will not show vm and VM off course is not under any project. I can see VM under Virt manager, on compute node. But I dont see see a way of making VM entry in mySQL or otherwise. Any ideas? or any other thoughts on migrating VM ?

/etc/neutron/neutron.conf from compute node - grep root_helper neutron.conf

root_helper = sudo neutron-rootwrap /etc/neutron/rootwrap.conf

I checked, what is suggested above, looks like those files are already in place, and populated correctly I tried putting above lines instead, but same result.
