From 4c6142e0991228f1aeb2075a553200d75a725017 Mon Sep 17 00:00:00 2001 From: Sergey Dyasli Date: Fri, 25 Oct 2019 11:59:35 +0200 Subject: [PATCH] x86/shim: fix ballooning down the guest MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently ballooning down a pvshim guest causes the following errors inside the shim: d3v0 failed to reserve 512 extents of order 512 for offlining And the ballooned-out pages stay inside shim and don't reach L0 Xen. Fix this by passing the correct arguments to pv_shim_offline_memory() during a XENMEM_decrease_reservation request.
