...'' into if()/else if() sequence to make code change easy to review. Virtual interrupt delivery avoids Xen to inject vAPIC interrupts manually, which is fully taken care of by the hardware. This needs some special awareness into existing interrupr injection path: For pending interrupt from vLAPIC, instead of direct injection, we may need update architecture specific indicators before resuming to guest. Before returning to guest, RVI should be updated if any pending IRRs EOI exit bitmap controls whether an EOI write should cause VM-Exit. If set, a trap-like induced EOI VM-Exit is triggered....

...Below is a simple align_timer() which aligns to the end of every ms (we can add some boot option to control it): s_time_t align_timer(s_time_t time) { return time | (MILLISECS(1) - 1); } Is there any objections, comments or concerns for such a enhancement? BTW, current vpt code try to handle vLAPIC specially to give vLAPIC ticks a offset from other timer ticks like below: pt->scheduled = NOW() + delta; /* * Offset LAPIC ticks from other timer ticks.

If HVM guest Fedora 7 uses PIT and lapic timer, it can''t boot or install. The cause is: At some point, Fedora 7 disables PIT interrupt by "vioapic.redirtbl[2].mask = 1, vpic.imr.bit0 = 0 (unmasked), vlapic.lvt[LINT0].mask = 1", and enables vlapic timer interrupt generating; In vmx_intr_assist() -> pt_update_irq(), we always choose IRQ0 rather than vlapic timer interrupt, because: 1) is_isa_irq_masked(v, 0) returns false due to vpic.imr.bit0 = 0; 2) the PIT''s pt->last_plt_gtime is...

Hello, I''m trying to port one of our existing appliances (running on 64-bit Red Hat Enterprise Linux 6.4) to a Xen HVM guest . We''re seeing some very odd behaviour that doesn''t manifest on other platforms. The guest experiences intermittent lockups of a few seconds- shell sessions become unresponsive, and various software healthchecking in our application triggers,

Hi, I have been trying to get Hyperthreading to work in a Windows HVM on Xen 4.1.2 as described in ''xmexample.hvm''. I think I have set it up correctly, but I can''t seem to get it to work. There is not much documentation on it and most topics are from years ago. I''m curious to know to whether this functionality is still supposed to work. I''m aware that

Hi, Keir, Currently, HVM guests do not have access to performance counters. So it is not possible to use performance analyzer software such as vtune in HVM guest to analyze programme performance. Other usage of performance counters , for example, the NMI watchdog, won''t function either. This patch will enable performance counters in HVM guest. Currently, only Core 2 Duo is implemented.
