From: Zhang Xiantao <xiantao.zhang@intel.com> With virtual EPT support, L1 hyerpvisor can use EPT hardware for L2 guest''s memory virtualization. In this way, L2 guest''s performance can be improved sharply. According to our testing, some benchmarks can show > 5x performance gain.

The value of ACPI PM-Timer may be broken on save unless the timer mode is delay_for_missed_ticks. With other timer modes, vcpu->arch.hvm_vcpu.guest_time is always zero and the adjustment from its value is wrong. This patch fixes the saved value of ACPI PM-Timer: - don''t adjust the PM-Timer if vcpu->arch.hvm_vcpu.guest_time is zero. - consolidate calculations of PM-Timer to one

Hi! Attached patch removes gfn_to_mfn_current(). It is redundant and effectively unused. All remaining users now use proper replacement function. => No functional change. While here, silence stdvga and use page_mode_hap() consequently.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Windows SVVP tests requiring a HPET ACPI table is in my opinion not a valid reason to always expose that table - respective tests should be run with "hpet=1" in the guest config file. The problem here is that at least with qemu-traditional, which by default doesn''t appear to emulate a HPET, the advertising here can mislead an OS to believe that there actually is a usable HPET,

Hi, When dom0 is under heavy load any Vista or Windows 2008 HVM''s that are running and have multiple cpu''s assigned often BSOD with code 0x00000101 "A clock interrupt was not recevied ona secondary processor within the allocated time interval" It only happens if the load in dom0 is high enough to make the mouse pointer lagged, once the mouse fails to track in

Three of the patches could be squashed in one, but it makes more sense to review them as three. These patches fix the case of an PVHVM guest not being able to resume propely b/c of hitting: 142 BUG_ON(info->type != IRQT_UNBOUND && info->type != type); (in events.c) and also adds a WARN to catch situations like these. The reason for this is that the Xen python toolstack
