I'm hoping we can some serious design discussion on that in the next few months. This is not the device namespace problem. This is the setns problem for mount namespaces, and the unprivilged mount problem. There may be a notification issue so use space can perform actions in a container when a device shows up. But it should be very possible on the host to call. setns(containers_mount_namespace); mknod(/dev/foo); chown(/dev/foo, CONTAINER_ROOT_UID, CONTAINER_ROOT_GID); And then from inside the container especially when I get the rest of the user namespace merged it should be very possible to manipulate the block device because you have permission, and to mount the partitions of the block device, because you are root in your container. But until the user namespace is merged you really are root so you can mount whatever. Daniel does that sound like the support you are looking for? Yes, the setns(mnt) approach you describe above is exactly what I'd like to be able todo, to solve the first half of the problem.

I'm guessing this is what Serge was refering to as the 'device' namespace problem Getting the device to always appear with the name /dev/sda is easy. Where does the need to have a specific device come from? I would have thought by now that hotplug had been around long enough that in general user space would not care. The only case that I know of where keeping the same device number seems reasonable is in the case of live migration an application, in order to avoid issues with stat changing for the same file over the transition, and I think a synthesized hotplug event could probably handle that case. Is there another case besides buggy applications that have hard coded device numbers that need specific device numbers? There isn't any particular buggy application we're trying to avoid here. We're just trying to provide an piece of OpenStack functionality to LXC in the same way as its provided to KVM. With a basic OpenStack instance, you just get the root filesystem from the image you booted, whose contents are transient (ie thrown away on shutdown). It is possible to tell OpenStack to attach one or more block devices to a running instance, which give you some persistent storage. The end user API for this lets the host admin specify the device name that the block device will appear as inside the instance. eg, with KVM you'd invoke: # nova volume-attach myguest mystoragevol1 /dev/vdb # nova volume-attach myguest mystoragevol2 /dev/vdc Obviously with KVM this just works, because you have a level of indirection between host guest device names via virtio-blk. The desire is to be able to wire up LXC in a similar way # nova volume-attach myguest mystoragevol1 /dev/sdb # nova volume-attach myguest mystoragevol2 /dev/sdc So it is really the host admin specifying that they want to provide the container with a '/dev/sdb' device, regardless of what the actual device node on the host is (it could be an iSCSI LUN, multipath LUN, LVM volume, or whatever). So I'm really looking to have the container visible device name be independent of host name.

Hello guys, i've some servers at hetzner, i've actually installed essex on those and they're working fine, the step i'm missing is that hetzner gives you additional ip fixed to one host or failover ip that i can move to one server to another with the api. What i want is to assign floating ip to vm, depending on which host the vm is running or use a create hook to move the failover ip to the host which is running the vm. Is it possible in some way?

As you say, figuring out the libvirt Nova test framework is not entirely
easy, particularly if you're new to Python / Nova. So to help you get
your patch through review, here is one suitable test case you can add to

The part of the problem is that I have a /dev/sdf, or even a /dev/volgroup00/logvol3 in the host (with whatever major:minor number that implies), and I want to be able to make it always appear as /dev/sda in the container (with the correspondingly different major:minor number). I'm guessing this is what Serge was refering to as the 'device' namespace problem Right. Getting the device to always appear with the name /dev/sda is easy. It's easy to log in and make it look that way. It's not easy to make all distros see it that way across boot. Where does the need to have a specific device come from? I would have thought by now that hotplug had been around long enough that in general user space would not care. Yes the *primary* need for the devices namespace is to prevent udev storm in the host and send uevents to the right place, and macvtap and loop devices. The only case that I know of where keeping the same device number seems reasonable is in the case of live migration an application, in order to avoid issues with stat changing for the same file over the transition, and I think a synthesized hotplug event could probably handle that case. Is there another case besides buggy applications that have hard coded device numbers that need specific device numbers? Other cases where specific device maj-min numbers are important are things like makedev. There is lots of software, and especially automatic update software, which insists that things have specific 'correct' maj-minor numbers. FWIW my (presumably naive) view is that for each non-init devicens we'd have a list of type-major:minor::type2-major:minor2 (:: meaning maps-to). Then if a uevent comes through not aimed at any type2-major2:minor2 valid in the namespace, that ns doesn't get the uevent. -serge ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

Re: [Openstack] Per host floating ip
I have limited knowledge of OpenStack, but I host many servers with Hetzner and know their infrastructure well. Since nova allows you to assign specific floating IPs to specific instances you could do the following. Create a floating range include all of the IPs Hetzner has given you. Then just associate the IP from the underlying host with a VM running on it that host using euca-associate-address.

For those of you who are likely to attend, is anyone else interested? It's not a huge amount of time invested on my end to put together the proposal, but I'd like to gauge the community interest before doing so. I would likely broaden things a bit from being exclusively Openstack and instead turn it into more of an HPC in the Cloud session so that we could, perhaps, take some input from other HPC cloud projects.

Re: [Openstack] [OpenStack][Nova] Live Migration Error
Not sure if you are able to debug this, but a while ago there was a bug
where instance.id was passed where instance.uuid was expected. This used to
cause some problem.
It looks like you are using distribution package rather than devstack
installation, so it is likely that the issue is now fixed. Can you try
latest packages (and/or try devstack if you can)

It looks like you are using distribution package rather than devstack

latest packages (and/or try devstack if you can)

Re: [Openstack] Per host floating ip

[Openstack] [Nova] Networking changes and quantum

Re: [Openstack] [Nova] Networking changes and quantum
Hi Ryan, L3 + Floating IPs are being added to Quantum in F-3 (got bumped from F-2). I haven't looked at your patch in detail, but it seems like you're looking to notice when a floating-ip is allocated or deallocated, and use that to trigger a change to the configuration of an external BGP daemon. Assuming that's the case, I'd much rather we take the approach of creating a notification API that would let you build this functionality as an external component process that feeds off of notifications about floating IPs being allocated and deallocated. We're looking at something similar for DHCP as well. This let's people implement custom functionality without having to modify the core code and config files. We have a blueprint to add such a notification framework to Quantum (likely based on work in Nova), but at this point, but its not clear when this will land (likely depends on whether it is used for DHCP improvements in F-3 or not). If you're interested in helping out with it, let me know.

It appears that each compute node (host) advertises it's existence into mysql directly. I find this is uncomfortable because it's going to be the bottleneck. If the max number of connections the mysql supports is 100, then does it mean only 100 compute hosts can be supported at the same time?
