SVI should be restored in case guest is processing virtual interrupt while saveing a domain state. Otherwise SVI would be missed when virtual interrupt delivery is enabled.

Change from v2: re-written code in ''vmx_intr_assist'' 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

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,

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,

The "APIC-register virtualization" and "virtual-interrupt deliver" VM-execution control has no effect on the behavior of RDMSR/WRMSR if the "virtualize x2APIC mode" VM-execution control is 0. When guest uses x2APIC mode, we should enable "virtualize x2APIC mode" for APICV first. Signed-off-by: Jiongxi Li <jiongxi.li@intel.com> diff --git

Hi, After c/s 18694 changed vHPET to vpt, for single HVM RHEL 5u1 guest idle case, our box will consume ~0.8W more power than before. The reason is two periodical vpts'' expires are hard to be aligned in the 50us soft timer SLOP. So we are considering a vpt specific enhancement which could try to just align periodical timers within vpt. A generic enhancement is to add a new interface

From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this

hvm_enable() copies the table contents rather than storing the pointer, so there''s no need to keep these tables post-boot. Also constify the return values of the per-vendor initialization functions, making clear that once the per-vendor initialization is complete, the vendor specific tables won''t get modified anymore. Finally, in hvm_enable(), use the returned pointer for all

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

Hi, all Page offline can be used by many purpose, like memory offline, memory power management, proactive action when multiple CE error happen to one page etc. In virtualization environment without guest offline support, we think offline a page usually means replace the old page with a new one transparently to guest. Currently we are trying to add page offline support in Xen environment .
