These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as

Here is the latest version of the patches to package the ocaml libraries. Changes since last time: * rename the packages from libxen-4.1-ocaml* to libxen-ocaml* - we wont be looking to install multiple concurrent versions of the same package, so the version doesn't need to be in the package name * Removed superfluous GENCONTROL definitions - dh_ocaml does what we need * Removed

This is an update to the patches sent out on 25th October. I expect, as before, that some of the larger patches won't get to the list so they are also available here: https://github.com/jonludlam/pkg-xen/commits/for-debian6. Changes since last mail: * I have split out the unrelated change to include 2 extra header files in libxen-dev * I have removed some instances of brace expansion

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

The following set of patches package up the ocaml libraries that are part of the standard xen build. The patches are also currently available at: https://github.com/jonludlam/pkg-xen/commits/for-debian There are some things to note: 1. The 5 patches imported from xen-unstable are not, and will not go into the xen-4.1-stable series. However, the patches were created at the request of the

The following series of patches fill in most of the gaps in the OCaml bindings to libxl, to make them useful for clients such as xapi/xenopsd (from XCP). There are a number of bugfixes to the existing bindings as well. I have an experimental version of xenopsd that successfully uses the new bindings. An earlier version of the first half of the series was submitted to the last by Ian Campbell on
