Hi all, I have some puzzle about hvmloader in the path /tools/firmware/, they are: 1: Is hvmloader running in non-root mode? 2: If hvmloader runs in non-root mode, does it have its pagetable? when set GUEST_CR3 in vmcs? 3: How can I find the value of GUEST_RIP in vmcs is set to the entry point of hvmloader,when virtual machine do it first vm entry. Much Thanks! - henanwxr _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi I am using oprofile 0.9.3 on xen cs 16540 on an Intel system. When I look at the top "hot" functions, I see p2m_change_type being one of the top function in xen-syms. This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all when I am running my apps as I have put printk in the functions and they do

Changes from v1 to v2: - Use a macro to replace the hardcode in patch 1/3. This patchset fixes issues about IA32_VMX_MISC MSR emulation, VMCS guest area synchronization about PAGE_FAULT_ERROR_CODE_MASK/PAGE_FAULT_ERROR_CODE_MATCH, and CR0/CR4 emulation. Please help to review and pull. Thanks, Dongxiao Dongxiao Xu (3): nested vmx: emulate IA32_VMX_MISC MSR nested vmx: synchronize page

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

Hello, This series has been split into two patches, one for arm and one for x86. I figured that this was easier than doing it as a single combined patch, especially as the changes are functionally independent. x86 has been boot tested, but arm has not even been compile tested as I lack a suitable cross compiler. However, the changes are just text replacement, so I dont expect any issues. The

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
