similar to: [PATCH] vmwrite high 32 bits of 64bit VMCS fields when in PAE mode

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

The first and third patches are cleaned up versions of an earlier v3 submission by Yang. 1: Nested VMX: check VMX capability before read VMX related MSRs 2: VMX: clean up capability checks 3: Nested VMX: fix IA32_VMX_CR4_FIXED1 msr emulation 4: x86: make hvm_cpuid() tolerate NULL pointers Signed-off-by: Jan Beulich <jbeulich@suse.com>

Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

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.

Dear all; Has anyone tried the new CPU (codename Yonah) produced by Apple? I heard from the engineer of Apple that MacBook Pro is already reachable, although it is not distributed to the public until February. If anyone has some information, I would like to buy it to enlarge the frontier. -- Does Yonah demand xen/i86 or xen/ppc? Or we need brand-new source code? That is the problem. Is

Hi all, Please can anybody explain how communication(direct or indirect) happens between xen and guest os(windows) in full virtualization mode. Both from VMM to guest and from guest to VMM.

Fix PAE shadow on a machine with RAM above 4G on x86_64 xen. Currently, on a machine with RAM above 4G, we can not run 32bit VMX guest on x86_64 xen, the root cause is that the PAE page table PDPT must below 4G, this patch fixes this issue. Also did some cleanup. Signed-off-by: Xin Li <xin.b.li@intel.com> Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>

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

Currently, Xen does not support injecting an NMI to HVM guest OS. Adding this feature is necessary for those softwares which depend on NMI to function correctly, such as KDB and oprofile. The attached patch allows NMI to be injected to guest OS in NMIP capable platforms. It also enables to queue an NMI and then inject it as soon as possible. Signed-off-by: Haitao Shan

Hi, I know this may be very basic question but I need some help . Actually I installed VM using the Xen Administrative console. Now I need to change the configuration file as I need to passthrough (using the pci-hide) a SCSI contoller from Dom0 to DomU. But I couldnot find the configuration file. Where can I find the Configuration file for this DomU? Actually I added the

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.

Dear R-developers, I would appreciate any insights over compiling R 3.4 with Intel MKL -- I have been successful until R 3.3.3 but now it stops complaining about pcre though it worked without Intel MKL as follows, ./configure LDFLAGS=-L/genetics/data/software/lib CFLAGS=-fPIC -I/genetics/data/software/include --enable-R-shlib I have used, export MKL_NUM_THREADS=15 export

The previous order of relinquish resource is: relinquish_domain_resources() -> vcpu_destroy() -> nvmx_vcpu_destroy(). However some L1 resources like nv_vvmcx and io_bitmaps are free in nvmx_vcpu_destroy(), therefore the relinquish_domain_resources() will not reduce the refcnt of the domain to 0, therefore the latter vcpu release functions will not be called. To fix this issue, we need to
