Roger, see: http://www.gossamer-threads.com/lists/xen/devel/325784 I had seen this few weeks ago, but could not reproduce last week despite several attempts. You are seeing this in V10 because I dropped the vioapic patch from V9 (included below). BTW, since I'm not able to reproduce this, can you kindly check where the ept violation is coming from? Is that on an io space? Also, our binaries don't match, so can you please confirm it's the call from: hvm_hap_nested_page_fault(): if ( (p2mt == p2m_mmio_dm) || (access_w && (p2mt == p2m_ram_ro)) ) { put_gfn(p2m->domain, gfn); if ( !handle_mmio() ) <========== hvm_inject_hw_exception(TRAP_gp_fault, 0); In which case, what's the p2mt? thanks, Mukesh diff --git a/xen/arch/x86/hvm/vioapic.c b/xen/arch/x86/hvm/vioapic.c index d3c681b..0b343bd 100644 --- a/xen/arch/x86/hvm/vioapic.c +++ b/xen/arch/x86/hvm/vioapic.c @@ -238,10 +238,11 @@ static int vioapic_write( static int vioapic_range(struct vcpu *v, unsigned long addr) { - struct hvm_hw_vioapic *vioapic = domain_vioapic(v->domain); + struct hvm_vioapic *vioapic = v->domain->arch.hvm_domain.vioapic; + struct hvm_hw_vioapic *hwapic = domain_vioapic(v->domain); - return ((addr >= vioapic->base_address && - (addr < vioapic->base_address + VIOAPIC_MEM_LENGTH))); + return (vioapic && (addr >= hwapic->base_address && + (addr < hwapic->base_address + VIOAPIC_MEM_LENGTH))); } > PXELINUX 4.02 debian-20101014 Copyright (C) 1994-2010 H.
