Re: [Openstack] Devstack +XCP/XenServer Kernel Panic
Thanks for the help/advice all. I did have root squashing disabled, but something else must've been playing up. I did the build on another machine and it's working now.

Re: [Openstack] Devstack +XCP/XenServer Kernel Panic
No worries, as I mentioned previously, my main production Openstack install is Diablo/Ubuntu/KVM, I'm just looking into XenServer as a potential future route. I'll keep an eye out for any news on the pack. I'm sure you have what you need already, but if you want a user with some servers to test installing the pack, I'm happy to help! /Kieran On 22 Mar 2012, at 14:59, John Garbutt wrote: Afraid I haven’t finished producing the supplemental packs yet (might be a few weeks till I get around to finishing that stuff off).

Re: [Openstack] Devstack +XCP/XenServer Kernel Panic
Hi, I used build_domU.sh (also tried the multi scripts, but got the same error). I was root for everything. I'll have to hold off on sending output. The servers are mid way through a reinstall.

We are working on getting the wiki up to scratch as a first step: http://wiki.openstack.org/XenServer I have not seen this error myself. How did you install the xva image? Did you use build_domU.sh? Where you running as route when doing build_xva? Can you give me the output of xe vm-param-list for your VM? I can compare that with mine to see if there are any settings that could be causing the issue (like not being in the correct PV-mode, or similar, although not seen that cause a kernel panic myself) Thanks, John From: openstack-bounces+john.garbutt=eu.citrix@lists.launchpad.net [mailto:openstack-bounces+john.garbutt=eu.citrix@lists.launchpad.net] On Behalf Of Kieran Evans Sent: 17 March 2012 4:38 To: openstack@lists.launchpad.net Subject: [Openstack] Devstack +XCP/XenServer Kernel Panic Hi all, I'm not sure if this is the right place for this (and if not, can anyone point out where).

Re: [Openstack] Audit Trail
This could be an issue auditing failed requests, i.e. when unauthorised requests are made against an api, if I understand correctly, those would be dropped before being put on the queue. Also, I thought that if written as a middleware wsgi component, no modification of the existing code would be necessary, it would just be a change in a config file. Or am I misunderstanding again? /Kieran On 8 Mar 2012, at 02:01, heut2008 wrote: May be get user actions from message queue is more efficient,also,in this way,you need not change the nova code. 2012/3/7 Kieran Evans keyz...@gmail.com Hi There, I'm looking at implementing some form of Auditing/logging for various components, with the main aim of having a full audit trail of all user actions, for various legal, and general troubleshooting/support purposes. Firstly, I'm wondering if there's already an implementation of something like this, or an effort towards it. I've had a look, but didn't see anything relevant. Secondly, I'm trying to work out the best approach to this. My first guess would be a WSGI middleware on all the APIs that logs every request, either to a message queue for log service to pull and put into a DB, or put it directly into a DB. If done as middleware, I envisage it being quite a simple, lightweight one, as it only has to pull the needed data from the request before sending it on. Any and all comments are welcome, I stumbled onto this idea this morning, so I've only had a few hours thinking about it while working on other things.
