Subject: [PATCH for-4.5 v5 09/16] tools: Add limited support of VMware's hyper-call rpc
Date: Wed, 17 Sep 2014 12:31:08 -0400 [thread overview]
Message-ID: <1410971475-15019-10-git-send-email-dslutz@verizon.com> (raw)
In-Reply-To: <1410971475-15019-1-git-send-email-dslutz@verizon.com>
This guestinfo support is provided via libxc. libxl support has
not be written.
Note: VMware RPC support is only available on HVM domU.
This interface is an extension of __HYPERVISOR_HVM_op. It was
picked because xc_get_hvm_param() also uses it and VMware guest
info is a lot like a hvm param.
The HVMOP_get_vmport_guest_info is used by two libxc functions,
xc_get_vmport_guest_info and xc_fetch_all_vmport_guest_info.
xc_fetch_all_vmport_guest_info is designed to be used to fetch all
currently set guestinfo values.
