Re comment #44:
There has been a ring buffer char device named ringbuf available
upstream in QEMU as Anthony suggested in comment #23 like following:
qemu -chardev ringbuf,size=640k,id=foo -serial chardev:foo
And the QMP commands have already been exposed by QEMU like:
{ 'command': 'ringbuf-read', 'arguments': arguments: { device:
foo, size: 1000, format: utf8 } }

I think it's legitimate to consider that the flaw is in qemu or libvirt, for copying console data from guest to host without much possibilities of controlling it.

[Bug 832507] Re: console.log grows indefinitely
Just to brainstorm: Are any of the following possible?? 1. Correctly have libvirtd configure and manage the console log file size. Some new XML configuration for the domain.xml format could be provided to alter the behavior? How much of the libvirt code would have to change for this? 2. If #1 isn't possible, then I presume we could use libvirt's 'named pipe' console capability and attach our own daemon to do the same as #1 (where we would use said daemon to read on said pipe and restrict the output files size). Of course how does this handle restarts or daemon failures. Basically this daemon would be the ring buffer 'maintainer' while libvirt would just feed it info. 3. Use a pseudo-tty to do something similar to #2? @Michael, be interested to hear what u think. Personally I think the libvirtd project is where this belongs (via #1) since it already has a daemon (libvirtd) and knowledge about which instances are active, console config, and such. I assume this hasn't been fixed in libvirt (or as a feature request). I'm not an expert on that code-base but if I had pointers perhaps that is the correct way to go about this (or its a dual-approach). -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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

We recently had a console log grow to 5.5GB When a user tries to get the console via the API it in turn packs this into a message and sends it off to rabbitmq.

[Bug 832507] Re: console.log grows indefinitely
The reason for the qemu-kvm task is that we think qemu-kvm is really the ultimate right place to add a '-serial ringbuffer:640k,file=/path/to/file' flag. All the other attempts are more hacky, but if upstream kvm had this , libvirt could expose it, and openstack could use it. I do not know whether or not it would be accepted upstream. This is an interesting idea worth proposing to QEMU upstream to see what their feelings are on this - with this kind of concept, their reaction can be quite unpredictable, so I can't say more than a 50/50 chance they'll go for it. The reason I think they might not go for it, is that it implements just one out of many potential different policies. eg, a viable alternative would be to rotate log files periodically instead of using a ring buffer. If KVM doesn't care todo this, from a libvirt POV, I have long imagined the need for a libvirt_vmlogd daemon which would run independently of libvirtd or QEMU. The QEMU guests would be configured with either a PTY or more likely a UNIX socket (eg '-serial unix:/var/lib/libvirt/qemu/serial0.socket'). The libvirt_vmlogd would automatically connect to the sockets as each guest was launched, and log the data according to some policy it is configured with, and handle log rotation / expiration etc. For the sake of the Nova security issue, I think it'd be wise to implement a fix in Nova regardless, since both the upstream approaches could take some time. -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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 832507] Re: console.log grows indefinitely
I don't understand what the file argument would mean. Once you write()
to a file, QEMU no longer can implement a ring buffer (it cannot discard
written data). You would need to do something like the following:
qemu -chardev memchr,max-capacity=640k,id=foo -serial chardev:foo
And then introduce QMP commands like:
{ 'command': 'memchr-read', 'arguments': { 'chardev': 'str', 'size':
'int' }, 'returns': 'str' }
We already have a memory character device that we don't expose
externally yet. It's just a matter of implementing a ring queue
behavior and plumbing things up. I think it's entirely reasonable and
perhaps would even be something that libvirt would prefer to use in the
long term over ptys.
Would also be good for unit testing.

[Bug 832507] Re: console.log grows indefinitely
Anthony, The file would be a disk-based ringbuffer. There would need to be a well-known disk-based ringbuffer format, which currently doesn't exist. Perhaps a libringbuffer to encapsulate it. The format would need head and tail indexes and then the data, together with some thought for concurrent access (eg. a mutex which would require mmapping to use). I imagine a libringbuffer which would expose methods to open a disk- based ringbuffer file, add data to the end of the buffer and read data out of it. -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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 832507] Re: console.log grows indefinitely
Having examined the idea of the libvirt_consoled a bit more, I think it is not actually required. It is possible to get good support for console logging, max bounded size, rollover, secure remote access, simply by dropping in the standard 'conserver' daemon with a suitable configuration file. There'd be no need for any new features in either libvirt or QEMU for this to work. All nova would need todo would be update the conserver.cf file whenever a VM is started or stopped. Reusing existing mature projects like conserver is perferrable to reinventing the wheel with our own half-baked solutions. -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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 832507] Re: console.log grows indefinitely
conserver is in Debian non-free, and thus unsuitable. conserver would still needed to receive the log output from qemu via a FIFO or similar, and this introduces the problem of what qemu should do when it is blocked on writing to conserver, which is where I think my previous patch failed (and I did warn about this in advance!). And conserver only supports log rotation, rather than a ringbuffer. This would make get_console_output useless if it was requested just after the log rotated, without extra complex glue. The code to work around these issues would be more complex than just not using conserver, IMHO. In any case, conserver is massive overkill for the need here, which is to have a simple ringbuffered console log. -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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 832507] Re: console.log grows indefinitely
IMHO having fixed size rotated logs per VM with max number of files, is a better solution that a ringbuffer. It really doesn't complicate the code that much to have to potentially just read a few lines from a second rotated logfile. While I agree that conserver is overkill if satisfying the requirements of the get_console_output() API contract is all that's required, I am thinking of the bigger picture, improving the console functionality available for the libvirt Nova driver in general. -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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

I think this would need a libringbuffer as nova would need to read the same file in get_console_output. When I first looked at this in September, I could not find such a thing, or any accepted on-disk format. The python code in my patch could be a good starting point, but there a couple of things I think needed to be added.

What I have so far: everything except point 6 in the plan above.
Problems:
1) libvirt creates an AppArmor profile for console.fifo and not
console.fifo.{in,out}.
Other things to check:
1) Console logging gets resumed correctly on restart.
2) Correct management of live migration.
3) Correct management of rescue mode.
Patch-in-progress attached, along with AppArmor details to get the
dynamic profile fixed. I can't see how to attach multiple files so I
hope a tarball is OK.

* Using named pipes / fifo would seem to re-introduce the same issue differently. * Logging to unix socket would mean there needs to be a listener within nova to suck in the log to file, but means it's handled in userspace (good). * Using a non-standard kernel module called emlog is interesting, but would need to be opt-in due to it's non-mainline nature. ** Tags added: server-o-rs -- 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/832507 Title: console.log grows indefinitely To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/832507/+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
