[Openstack] OpenVSwitch Agent

Hi All, In the openstack architecture, what are the exact reasons for running the OpenvSwitch agent on all the compute nodes. Is it for portability reasons? Can we avoid the implementation of agent in the openstack architecture? Thanks in advance. -- Regards Neelakantam Gaddam

[Openstack] [Quantum] Review days for Quantum core devs

Hi, During our last project meeting there was some interest in introducing review days for Quantum core devs. I see multiple benefits in this approach: 1) Contributors would know which core member the need to contact on a given days for soliciting a review for their patches 2) Predictable code

Re: [Openstack] Can't launch VM with XCP plus OpenStack Essex release version

It is not well documented (I promise to work on that soon), but you should use an EXT3 local SR, not LVM. It is certainly worth moving to EXT3, just to rule a few things out. I see you are using the Ubuntu XCP packages. This is a version of XenAPI I have not yet started doing much QA on, but I

Happy to help :-) You shouldn't need to use kpartx yourself. We may need to use it in the nova code where we try to mount VDIs in Dom0 (in XenAPI plugins) Long term, I should probably look at ways around doing that. Cheers, John -Original Message- From: suz...@midokura.jp

dnsmasq supports setting parameters such as the gateway IP and other settings based on tag. I have run a patched version of nova-network in the Diablo time that used the network DB label field as the network tag in dnsmasq. This then allows you to set custom configs by modifying the dnsmasq.conf
