similar to: Problem with using Libvmi or xenaccess with xen

Hello, I''m interested in establishing a communication channel between the Xen hypervisor and a dom0 userspace application. Ideally this would be a 2-way channel, with the hypervisor asynchronously notifying this application, and then (for certain types of messages) wait for a reply from the userspace consumer. To this end, I''ve been reading xen-devel posts [1], read the

Hello, I''m interested in using the mem_event API (or it''s LibVMI wrapper), but I''m interested in capturing write events anywhere in a domU guest''s memory, _and_ not just once for each page write, but every time a page is being written to. To this end, I''ve looked at the xen-access.c example, where at first all the pages are being monitored:

I''m pleased to announce a new project called XenAccess. The project goals are to provide a full featured introspection library for Xen. Introspection is a technique where applications in one domain can view memory from another domain. For example, you can run an application in dom0 to list the processes or LKMs in a domU. More information is available on the website:

hi all: I am trying to use libguestfs to manage my vm disk , I want to use guestfs-lib the C library on ubuntu 12.04. so I download libguestfs-1.28.1 and try to install it . what I did is : ./autogen.sh ./configure make this time some errors occurs : File "output_libvirt.ml", line 53, characters 4-13: Error:

As I know, you can use Libvmi API to access the memory of VM and then walk through the double-linked list of process to reconstruct the process list. it is easy, and libvmi has provide the example 在2015-04-20 22:52:02,hanyandong<hanyandong@iie.ac.cn>写道： > On 20.04.2015 06:22, dt sweval wrote: > > Hi > > I wanted to find out if there is way to list all the running processes

Hi ,all : thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu 12.04 to manage vm disk created by KVM. I downloaded libguestfs-1.28.1.tar.gz ,and then executed (1) ./autogen.sh (2) ./configure (3) make (4) make check .there is the error. /usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl md_create: feature 'mdadm' is not available in this

Hi guys, I am new to QEMU-KVM, libvmi and libvirt stuff. Libvmi uses libvirt. I am trying to to run process-list example of libvmi and getting error as below. It seems that this error may be due to libvirt as it is not able to find domain. I seek your kind help on below error: spanhal1@seclab2:~/KVMModule/libvmi-0.10.1$ sudo ./examples/process-list ubuntu libvir: QEMU error : Domain not found:

Hello all, I have been looking through the internet and through the wiki, trying to find something which explains in details the available interfaces with which one might be able to insert some code to make some slight additions to Xen functionality. I am doing some research on the possibility of adding some extra functionality to Xen, and my supervisor has mentioned that these are things worth

HI all: my problem is : I want to use libguestfs on other project. if I just run a test C programm It works well just run : cc prog.c -o prog -lguestfs -I /usr/libguestfs/libguestfs-1.28.10/src/ I write a C programm in my project , after that I run make , it happend: /usr/nitro/libvmi-master/libvmi/.libs/libvmi.so: undefined reference to `guestfs_launch'

Hi all. I''m now try to read and write puseud physical memory of domU from Dom0 with xenaccess(this is using libxc). #http://xenaccess.sourceforge.net/ With xenaccess, I''m succeeded read and writing almost of the memory. But It fail when I try to access head 1M region and some bit regions. To be precise, xc_map_foreign_range() of libxc returns error code. **

Hi I wanted to find out if there is way to list all the running processes in a guest VM from the hypervisor. Like the output of 'ps -ef' from inside the guest VM, but without logging in or ssh into it. Thanks dtsweval

- This minor patch implements the missing stub function security_label_to_details in the dummy module. This stub function is necessary to create domains with network interfaces for modules that do not implement the security_label_to_details function.

While compiling XEN with XSM_ENABLE=y and FLASK_ENABLE=y, I received the following error. gcc -O1 -fno-omit-frame-pointer -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement -Wno-unused-but-set-variable -fno-builtin -fno-common -Wredundant-decls -iwithprefix include -Werror -Wno-pointer-arith -pipe

The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl

This patch set adds XSM security labels to useful debugging output locations, and fixes some assumptions that all interrupts behaved like GSI interrupts (which had useful non-dynamic IDs). It also cleans up the policy build process and adds an example of how to use the user field in the security context. Debug output: [PATCH 01/10] xsm: Add security labels to event-channel dump [PATCH 02/10] xsm:

Hi all, i want to know about the following things: 1.unloading XSM policy. -xl loadpolicy xenpolicy.24 to load the policy. For unloading is there any command is available.? 2. i want to know any analysis tool is available for XSM policy. 3. Apart from wiki.org/XSM any other tutorial is available for developing own XSM policy.? Thanks and regards, cooldharma06.

Hi all: I installed libguestfs-1.29.40 on both ubuntu 12.04 and ubuntu 14.04. Both of them have the same problems,It is about the 'AVAILABILITY' .

hi all, i am new to the libvirt. Via libvirt i am converting my xen.com.sfg. In xen i added xsm label as, seclabel:system_u:domU_t. but after creating vm using xen or by convertdom-to-xml also does not contain any label or text with xen-4.2.1. in the documentation also you mentioned selinux label (sVirt) only. Can u clear me the following things: 1. How to use XSM label in libvirt.? 2. What
