similar to: [PATCH][VT][RESEND] Patch to remove ignored setting in VMCS for VMX domains

TPR shadow/threshold feature is important to speedup the boot time for Windows guest. Besides, it is a must feature for certain VMM. We map virtual APIC page address and TPR threshold from L1 VMCS, and synch it into shadow VMCS in virtual vmentry. If TPR_BELOW_THRESHOLD VM exit is triggered by L2 guest, we inject it into L1 VMM for handling. Besides, this commit fixes an issue for apic access

This patch removes the ignored "Unconditional I/O exiting" setting in VMCS for the vmx guest since "Use I/O bitmaps" setting is being used. -Himanshu -- ------------------------------------------------------------------------- Himanshu Raj PhD Student, GaTech (www.cc.gatech.edu/~rhim) I prefer to receive attachments in an open, non-proprietary format.

Attached is patch for HVM guests (VMX only) that prints VMCS areas for all vcpus. A new hotkey (''v'') triggers the dump. We also print VMCS for current processor when vmenter fails. -boris _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the

Hi Folks, I need some large chunk of physical memory, so I allocate it early using alloc_bootmem_low_pages and use it later (akin to bigphysarea patch). The trouble I am having is the following. Suppose the virtual address for the memory area is 0xc14d6000. After xen_create_contiguous_region call, I do a virt_to_bus and the bus address comes out to be 0x18000000. So far so good. However,

Hi Folks, I saw some references to the same problem in mailing list but no solution. I am running a DomU with PHYSDEV access. With fedora core 4, I just changed the inittab file to not start getty''s on tty1-6, and it worked (only ttyS0 is enabled). However, same trick didn''t do it for debian. I can boot into a shell if I put init=/bin/bash on kernel command line. However,
