[libvirt] [PATCH] Fix UUIDString for python bindings
by Cole Robinson 10 Jun '08

10 Jun '08

The attached patch fixes a few issues in the python bindings. First, UUIDString has, to my understanding, never worked. It expected to be passed a buffer to fill with the uuid, which through my tests isn't realistically doable from python. I added custom bindings to fix this, and it now works as expected, taking no arguments and returning a string. UUID for a storage pool wasn't being generated with its custom function, so it too was broken. This is also fixed. I also removed some stale entries for virStorageVol UUID functions from generator.py which were probably just carried along from an old version of the storage api patches (storage volumes don't use UUID).

[libvirt] [PATCH] virDomainMemoryPeek - peek into guest memory
by Richard W.M. Jones 10 Jun '08

10 Jun '08

This patch implements virDomainMemoryPeek, which allows callers to peek into guest (virtual) memory. Currently the patch contains a QEMU driver and remote support. There's also a big comment in the source describing how to do Xen. Obviously the use case for this is virt-mem: http://et.redhat.com/~rjones/virt-mem/ Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones Read my OCaml programming blog: http://camltastic.blogspot.com/ Fedora now supports 59 OCaml packages (the OPEN alternative to F#) http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora

[libvirt] [PATCH] lxc: new tty for container
by Dave Leskovec 10 Jun '08

10 Jun '08

The lxc driver xml parser treats the console element as input when it should be output only. This obviously causes problems when anything other than /dev/ptmx is specified or when a container is shutdown and then restarted without redefining it (so that the console field is reset). This patch treats the console element as output only and always creates a new device when starting a container. Also fixed up a string overflow when storing the device name. Thanks! -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

[Libvir] Reopening the old discussion about virDomainBlockPeek
by Richard W.M. Jones 09 Jun '08

09 Jun '08

Virt-df[1] has now gained the ability to fully parse LVM2 partitions, thus: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap However it still has to do it by opening the local partitions / files, which means it isn't using a "proper" part of libvirt and more importantly it cannot run remotely. I'd like to find out whether the time has come for us to look again at a virDomainBlockPeek call for libvirt. Here is the original thread plus patch from 7 months ago: http://www.redhat.com/archives/libvir-list/2007-October/thread.html#00089 (I've attached an updated patch against current CVS). I appreciate that some cases might not be simple (iSCSI?), but the same argument applies to block device statistics too, and we make those available where possible. I think a best-effort call allowing callers to peek into the block devices of guests would be very useful. Rich.

[libvirt] Routing
by Dave Walker 09 Jun '08

09 Jun '08

Hi, I'm trying to set up routed networking using libvirt0.4.2, but not having much joy, I cannot ping from either the host OS, or elsewhere on the network (or inverse from the guest OS). I would really appreciate some assistance as I haven't been able to find many routing examples. I'm using the example provided[0], which does create virbr1. If I can provide any further information, please let me know. $ ifconfig = http://pastebin.com/f69bf71bf $ route = http://pastebin.com/f69c73b03 $ cat /etc/libvirt/qemu/networks/default.xml = http://pastebin.com/f3fee05fb $ cat /etc/libvirt/qemu/ubuntu.xml = http://pastebin.com/f477c53a6 [0] http://libvirt.org/formatnetwork.html#examplesRoute Kind Regards, Dave Walker

[libvirt] PATCH: Fix check for inactive network
by Daniel P. Berrange 09 Jun '08

09 Jun '08

When building up the QEMU command line args we forgot to check for a NULL when creating the TAP device arg. This can happen if the network being connected to the VM is not running. This is something I broke in the refactoring of the ARGV construction in the QEMU driver. Dan.

[libvirt] [PATCH] QEMU & remote support for virDomainBlockPeek
by Richard W.M. Jones 05 Jun '08

05 Jun '08

This patch adds support for virDomainBlockPeek over remote. Also adds a QEMU driver implementation. Also there is a minor fix in the Xen driver impl. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

[libvirt] Workshop Virtualization Technologies in Essen, Germany
by Henning Sprang 04 Jun '08

04 Jun '08

Hello everybody! For the third time, I arranged a "Workshop on Virtualization Technologies" in cooperation with the Linuxhotel in Essen, Germany. Our goal is, to provide developers of Open Source Software related to virtualization, and interested, skilled administrators with the possibility to come together for a weekend to work on their projects, exchange experiences and play around with the technology. The Linuxhotel as a location delivers a great, relaxed athmosphere and a perfect infrastructure to enable carefree working. Details - currently in German only - here: https://wiki.villa-vogelsang.de/doku.php?id=virtualisierung:start It's no problems to attend the workshop if you're not speaking german - please let me know if you're interested, and I'll give you more info on the details - basically it is, if you are an OpenSource developer in a virtualization related field, you can attend for free, otherwise you have to pay a flat fee of 135 Euros. We're looking for sponsors to see if we can get to reimburse travel costs for the Open Source developers. I'd be glad to see you there! Registration will be by first come-first serve principle - the event will be limited to 20 Persons. Henning Sprang -- Henning Sprang http://www.sprang.de | http://lazyb0y.blogspot.com/
