[Bug 812548] Re: bridge not set up correctly with LXC and all-in-one system
I'm marking this as invalid. It was mostly user error on my part. I've got an improved version of the script here at https://gist.github.com/1169889 ** Changed in: nova (Ubuntu) Status: New = Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/812548 Title: bridge not set up correctly with LXC and all-in-one system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/812548/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 812548] Re: bridge not set up correctly with LXC and all-in-one system
** Description changed:
I'm attempting to demo/use LXC backend for nova in EC2, all on a single
system.
- When doing so, I get the following trace:
+ When doing so, I get the trace below. It appears that we can get further by
doing:
+ $ sudo brctl addbr br0
+ $ sudo ifconfig br0 up
+ $ sudo vconfig add br0 100

+ However, doing so just gets us further along to fail at bug 812553.

I'm adding an attachment with all of the setup that I did.

[Bug 812548] Re: bridge not set up correctly with LXC and all-in-one system
Scott- There is no network manager defined in nova.conf, so nova-network is defaulting to the VLAN manager which, IIRC, requires a separate physical interface to be available on which it builds bridges and VLANs, as well as some config flags in nova.conf. I've attached a modified version of your script that configures the appropriate flags for using the FlatManager instead, deletes + re-migrates the sqlite database as it needs and sets up a bridge to use (I'd suggest using 11.0.0.0 or a subnet other than ec2's 10.0.0.0) This should at least get your networking provisioned, images delivered and built and instance launched. Keep in mind, there is an pending bug that effects the current oneiric build and will prevent you from launching anything ATM.
