Thanks for the feedback I take it from your answer that there is no current plan in the direction of adding this as a feature, right ? In this case, how would you welcome pull requests if we managed to add this on our side ? Many thanks — Thierry On 29 Jan 2014, at 14:27, Daniel P. Berrange <berrange@redhat.com> wrote:

Hi there

I’m not quite proficient with libvirt yet, and have been using it so far primarily to manage lxc containers I was hoping to find a means to configure the set of capabilities that guests should drop, but came across a few web pages suggesting these were set in stone in the code is this correct, or is there a means to tweak this set from the host via the xml config or a virsh command ?

any hint / pointer to documentation in this respect would be most appreciated

That's correct, there's no means to configure this from the libvirt XML config. The containers will be started with the maximal set of capabilities we can reasonably allow. The app inside the container can drop bits they don't require
