Subject: fixed location of share info page in HVM guests
Date: Mon, 27 Aug 2012 19:55:05 +0200 [thread overview]
Message-ID: <20120827175504.GA13051@aepfle.de> (raw)
Recently I tried to move the shared_info page in the pvops kernel during
shutdown, see "xen PVonHVM: move shared_info to MMIO before kexec"
patch. But this change was reverted because it caused reboot failures
because the actual moving of the shared page is fragile.
So my question is what can be done about it?
Right now the shared_info page is in the middle of the RAM and will be
overwritten during kexec because its area is not reserved.
Can the toolstack help to provide a reserved page which can then be used
by the kernel?
Olaf
