[libvirt] [PATCH] disk: Provide a default storage source format type.

https://bugzilla.redhat.com/show_bug.cgi?id=1181062 According to the formatstorage.html description for <source> element and "format" attribute: "All drivers are required to have a default value for this, so it is optional."

[libvirt] [PATCH] docs: add a note that attr 'managed' is only used by PCI devices
by Erik Skultety 02 Mar '15

Our documentation isn't 100% clear about hostdev 'managed' attribute usage, because it only makes sense to use it with PCI devices, yet we format this attribute to all hostdev devices. By adding a note into the docs, we can possibly avoid confusion from customer's side and also avoid a solution using ternary logic.

As reported on the libvirt-users list [1], there's new web application called mist.io which uses libvirt as one of its backends. Lets add it into our list of libivrt based applications. 1: https://www.redhat.com/archives/libvirt-users/2015-February/msg00096.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- docs/apps.html.in | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/docs/apps.html.in b/docs/apps.html.in index 4403ce6..79ee73a 100644 --- a/docs/apps.html.in +++ b/docs/apps.html.in @@ -404,6 +404,14 @@ functions, such as live migration that allows for load balancing between cluster nodes, monitoring CPU, memory. </dd> + <dt><a href="http://mist.io/">mist.io</a></dt> + <dd> + Mist.io is an open source project and a service that can assist you in + managing your virtual machines on a unified way, providing a simple + interface for all of your infrastructure (multiple public cloud + providers, OpenStack based public/private clouds, Docker servers, bare + metal servers and now KVM hypervisors). + </dd> </dl> <h2><a name="mobile">Mobile applications</a></h2> -- 2.0.5
