similar to: Hypervisor to dom0 communication

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:

Hi all, Can dom0 have enough privilege to access domu''s kernel memory using Libvmi functions? Libvmi use xenaccess functions in fact, and as it is a user space library I''m asking this. I wanna read system call table of domu through dom0. Thanks _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Add the new MEM_EVENT_REASON_MSR event type. Works similarly to the other register events, except event.gla always contains the MSR address (in addition to event.gfn, which holds the value). MEM_EVENT_REASON_MSR does not honour the HVMPME_onchangeonly bit, as doing so would complicate the hvm_msr_write_intercept() switch-based handling of writes for different MSR addresses, with little added

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

Hello!. How can i use @releaseDomain from dom0 to subscribe for domain destruction? I''m try to add watch for @releaseDomain path with token equal of needed domain id. But when another domain dies, i get domain that i provide via token to xs_watch. Is that possible to get id of domain what released from xenstore? -- Vasiliy Tolstov, Clodo.ru e-mail: v.tolstov@selfip.ru jabber:

Hello, assuming that the VCPU is paused while waiting for userspace to respond to a page fault mem_event, and userspace calls libxc''s xc_domain_hvm_getcontext_partial(... CPU ...) and tries to inspect RIP, is this a safe thing to do? Is RIP''s value guaranteed to be safe to inspect in this context? Thanks, Razvan Cojocaru

Made the xenctrl.h and xenstore.h easier to use with C++: added ''extern "C"'' statements, moved the definition of enum xc_error_code above it''s typedef, and renamed a ''new'' parameter (''new'' is a C++ keyword).

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. 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. **

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.

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

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, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
