[Xen-devel] libvirt/libxl implemetation of get_online_cpu / virNodeGetCPUMap?

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Hi,

A recent OpenStack nova commit make use of virNodeGetCPUMap to get the list
of online cpu of a host. But this API is not implemented for the libvirt
xen driver.

The commit:
  Add handling for offlined CPUs to the nova libvirt driver.
https://review.openstack.org/gitweb?p=openstack/nova.git;a=commitdiff;h=0696a5cd5f0fdc08951a074961bb8ce0c3310086

Is there a need to use this under Xen? (Is it possible to have offline
CPU?).
What libxl API those provide this information, if it exist?

I found libxl_get_online_cpus() but that not enough. They want a
bitmap.

Thanks,
