Hello everyone,

I use Openstack Quantum for my network management and set up an deployment accordingly to this guide: OpenStackFolsomInstallGuideWebVersion.rst from github. (Not allowed to post links)

Everything is working well except the network. I can ping the VMs over the associated floating IPs and also connect via SSH. Put the results of the ping are very odd. They start at 200ms and went down to 100ms. Each ping takes 1ms less than the previous. After reaching a ping of 100ms it goes up to 200ms again. The output of an ping can be found at the end of the question.

I pinged the Floating IP 192.168.100.105 from another VM with the floating IP 192.168.100.104. Also the data rate of an download into this VM is very slow. Although the network hardware between the web server and the VM provides at least 100Mb/s the download proceeds with 600KB/s.

Could you give me some hints, where to tweak my installation?

Regards, Hikhvar
