by Daniel P. Berrange 14 Sep '09

14 Sep '09

FYI I have just uploaded a new release 0.2.2 of the libvirt perl bindings, Sys-Virt, to CPAN. http://search.cpan.org/dist/Sys-Virt/ Direct download link http://search.cpan.org/CPAN/authors/id/D/DA/DANBERR/Sys-Virt-0.2.2.tar.gz Changes since 0.2.1: - Add all new APIs upto libvirt 0.7.0 APIs (listing defined network interfaces) - Add missing APIs for looking up storage volumes based on path and key - Fix lookup of network interfaces based on MAC address - Add missing APIs for defining network interfaces and starting defined interfaces There will of course shortly be another release to cover the soon to be released APIs in libvirt 0.7.1 Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

Re: [libvirt] Interface driver and ESX support
by Matthias Bolte 14 Sep '09

14 Sep '09

Okay, I finally got the patches cleaned up. I just posted this 12 patches series to the mailing list. Apply them all to an up to date git clone and apply the attached, updated ESX interface driver stub patch in the end. Patch 6 of 12 adds the binding for HostCpuIdInfo and contains the functions to handle ArrayOf* types.

[libvirt] [PATCH]: Bug when you try to start machines made will older VBox versions
by Pritesh Kothari 14 Sep '09

Hi All, Thanks to Florian, who pointed out the bug, due to which you can't start domains defined with older builds or with empty "FRONTEND/Type" tag in their xml files. Fixed it in the following patch. Regards, Pritesh

[libvirt] [PATCH 0/4] Changes to API/ABI for secrets handling
by Daniel P. Berrange 14 Sep '09

14 Sep '09

This series makes two changes to the public API and wire protocol ABI for the secrets handling support recently committed. As such this is a must fix before we do the release, since we can't break compatability once released. The first patch changes all the code to store UUIDs in raw format instead of printable format. This is important because it ensures that e3a9758f-b0c6-7a3a-ebb9-71a69c930289 is treated exactly the same as e3a9758fb0c67a3aebb971a69c930289, which is not the case with the currently committed code. It also makes the secrets and storage encryption XML parsers use the internal UUID handling APIs The second patch adds a new unique property to virSecretPtr. The "owner ID" is intended to be unique on a host wrt all secrets with matching usage type. This entails adding 2 APIs to querying the usage type, and another API to lookup a secret based on its usage. In testing the current code I frequently found myself getting into the situation where there were many secrets for the same volume which was not at all good. So if defining a secret to be used with a storage volume this ensures that you only ever have one secret associated with each storage volume path. The third patch ensures that when you query the XML for a qcow encrypted voluem, it will include the UUID of the secret. Previously if you created a volume, and then restarted libvirtd, the secret UUID would be lost. This patch is why we need the new API from the second patch virLookupSecretByUsage - without that it would be impossible to lookup the secret efficiently. THe final patch is a minor tweak to the RNG
