As the code stands right now, after DomU has enabled #VE using HVMOP_altp2m_vcpu_enable_notify, all its pages have the #VE suppress bit cleared, generating #VEs for any EPT violation. There is currently no way to change the value of the #VE suppress bit for a page from a domain; it can only be done in Xen internally using ept_set_entry(). Following the discussion from https://lists.xen.org/archives/html/xen-devel/2017-03/msg01312.html these patches introduce new hvmops for setting and getting this bit and thus Adrian Pop (2): x86/altp2m: Add a hvmop for setting the suppress #VE bit x86/altp2m: Add a hvmop for querying the suppress #VE bit Vlad Ioan Topan (1): x86/mm: Change default value for suppress #VE in set_mem_access() tools/libxc/include/xenctrl.h | 4 ++ tools/libxc/xc_altp2m.c | 50 +++++++++++++++ xen/arch/x86/hvm/hvm.c | 33 ++++++++++ xen/arch/x86/mm/mem_access.c | 107 +++++++++++++++++++++++++++++++- xen/include/public/hvm/hvm_op.h | 13 ++++ xen/include/xen/mem_access.h | 6 ++ 6 files changed, 211 insertions(+), 2 deletions(-) -- 2.18.0 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
