Re: [Openstack] URGENT: packet loss on openstack instance

Thanks Liping, I will check bug for tx/rx queue size and see if i can make it work but look like my 10G NIC support SR-IOV so i am trying that path because it will be better for long run. I have deploy my cloud using openstack-ansible so now i need to figure out how do i wire that up with opensta

Re: [Openstack] Can any user add or delete OpenStack Swift middleware?

You may be interested in Storlets. It's another OpenStack project, maintained by a Swift core reviewer, that provides this sort of user-defined middleware functionality. You can also ask about it in #openstack-swift --John On 16 Sep 2018, at 9:25, Qiao Kang wrote: Hi, I'm wondering wheth

Hi Satish, There are hard limitations in nova's code, I did not actually used more thant 8 queues: def _get_max_tap_queues(self): # NOTE(kengo.sakai): In kernels prior to 3.0, # multiple queues on a tap interface is not supported. # In kernels 3.x, the number o

Re: [Openstack] Can any user add or delete OpenStack Swift middleware?

Thanks Remo. What did you mean by using ACL? Does it mean different users can see different middleware pipelines? For instance, Alice: middleware_1 -> middleware_2 -> middleware_3 ... Bob: middleware_2 -> middleware_4 ... Is that feasible? Thanks, Qiao On Sun, Sep 16, 2018 at 6:05 PM Remo M

Re: [Openstack] Can any user add or delete OpenStack Swift middleware?

Users cannot install middleware. You can use ACL for users with the same share. Remo > On Sep 16, 2018, at 09:25, Qiao Kang wrote: > > Hi, > > I'm wondering whether Swift allows any user (not the administrator) to > specify which middleware that she/he wants his data object to go throught. >

Update on my last email. I am able to achieve 150kpps with queue=8 and my goal is to do 300kpps because some of voice application using 300kps. Here i am trying to increase rx_queue_size & tx_queue_size but its not working somehow. I have tired following. 1. add rx/tx size in /etc/nova/nova.conf

I successful reproduce this error with hping3 tool and look like multiqueue is our solution :) but i have few question you may have answer of that. 1. I have created two instance (vm1.example.com & vm2.example.com) 2. I have flood traffic from vm1 using "hping3 vm2.example.com --flood" and i ha

[Openstack] Can any user add or delete OpenStack Swift middleware?

Hi, I'm wondering whether Swift allows any user (not the administrator) to specify which middleware that she/he wants his data object to go throught. For instance, Alice wants to install a middleware but doesn't want Bob to use it, where Alice and Bob are two accounts in a single Swift cluster. O

I am currently playing with those setting and trying to generate traffic with hping3 tools, do you have any tool to test traffic performance for specially udp style small packets. I am going to share all my result and see what do you feel because i have noticed you went through this pain :) I wil

I think multi queue feature should help.（be careful to make sure the ethtool update queue number action also did after reboot the vm）. Numa cpu pin and queue length will be a plus in my exp. You may need yo have performance test in your situatuon，in my case cpu numa helpped the app get very sta

It is still possible to update rx and tx queues length if your qemu and libvirt version is higher than the version recorded in [3]. （You should possible to update directly in libvirt configuration if my memory is correct） We also have some similar use case which run audio/vedio serivcs. They are

Re: [Openstack] URGENT: packet loss on openstack instance

Hi Liping, Thank you for your reply, We notice packet drops during high load, I did try txqueue and didn't help so I believe I am going to try miltiqueue. For SRIOV I have to look if I have support in my nic. We are using queens so I think queue size option not possible :( We are using voip
