Hi Mukesh, I was auditing uses of set_xen_guest_handle for correctness when I noticed that gdbsx (specifically tools/debugger/gdbsx/xg/xg_main.c) defines its own _domctl_hcall and associated helpers instead of using libxc. Is there any particular reason for that? Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensourc...

Package: xen-utils-4.4 Version: 4.4.1-6 Severity: normal Dear Maintainer, The xen-utils-4.4 package in jessie is missing the gdbsx binary. This is useful to have when one wishes to debug Xen domains, and complicated to obtain if one does not have it ready. The same package on at least Ubuntu 14.04.1 LTS does contain this binary, in /usr/lib/xen-4.4/bin. However, if you have no objections I would prefer that the binary (or a...

I''ve followed the instructions in tools/debugger/gdb/README for building and using gdbserver-xen. While playing around with debugging a running guest or dissecting a core file, I''ve discovered that using it with a 32-bit PV domU fails but it works fine on the same guest if it''s booted with a 64-bit kernel. Is this a known limitation, or am I doing something incorrectly?

hi,all has anyone set the eflags.TF of vm? I want to introdeuce a VM into single-step by setting the eflags.TF of vm, then I disassemble the bytes at RIP to figure out what''s going on .

Hi all, this is the tenth version of the patch series to introduce upstream qemu and seabios in the xen-unstable build system. Changes to v9: - rename QEMU_UPSTREAM_TAG to QEMU_UPSTREAM_REVISION: we are going to use it with a branch name by default; - set QEMU_UPSTREAM_REVISION to "master" by default; - set SEABIOS_UPSTREAM_URL to git://xenbits.xen.org/seabios.git by default; - add

...ommon but am not sure how one would make a safe transition there. Maybe together we can work something out. Other than that, there are two (and maybe a haf) things that might be beneficial for Debian: 1. Users have noticed with Ubuntu's Xen-4.7 (still true with 4.8) that some tools (mainly gdbsx, but also some flask-* commands) are missing from the xen-utils-4.x package. This is because those end up outside the libexec path. The attached diff fixes this (a bit hackish) by simply copying all those into usr/lib/xen-$(VERSION)/bin/ 2. Splitting up xen.init. Initially driven by syste...

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 Ian/Stefano, So, I''m back to using pfn space from maxphysaddr below. Stefano, you suggested ballooning, but that would be just too slow. There are lot of pages to be mapped, 4k at a time during guest creation, and I am afraid ballooning and hypercalls to populate EPT will be pretty slow. OTOH, there is tons of address space available between max-physaddr and max pfn in dom0. Stefano,

Hi all, I try to use kernel 2.6.36.1 in HVM but building the drivers xen-blkfront, xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I try with ubuntu 10.10. In boot I receive error "Cannot find a root partition /dev/xvda2" and a prompt (initramfs) appear. In dmesg (initramfs) appear: blkfront: xvda: barriers enabled (tag) xvda: xvda1 vbd vbd-51712: 16

Initially out there as #965245. I strongly prefer to build ARM64 packages on non-ARM systems. Something about my main build machine having twice the cores and twice the clock speed. As such after many builds I've managed to generate a set of patches which appear to mostly function to get functioning cross-builds of Xen. These are NOT a 100% solution. Some packaging hacks were needed. In
