XenAccess Library: Introspection for Xen
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...

Problem with using Libvmi or xenaccess with xen
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

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
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

Mem_event API and MEM_EVENT_REASON_SINGLESTEP
...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: xc_hvm_set_mem_access(xch, domain_id, HVMMEM_access_rx, ~0ull, 0); xc_hvm_set_mem_access(xch, domain_id, HVMMEM_access_rx, 0, xenaccess->domain_info->max_pages); Then, after an event is received: xc_hvm_set_mem_access(xch, domain_id, HVMMEM_access_rwx, req.gfn, 1); thus allowing ''rwx'' access to 1 page starting at req.gfn. This strategy indeed allows me to inspect writes to any page of the guest OS, howe...

Hypervisor to dom0 communication
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

Xen interfaces / hooks
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
