libxenlight exports a function libxl_uuid2string which is used internally in several places but has one external caller in xl. The function mainly implements policy so should not be part of the libxenlight API. The extent to which it can be considered mechanism it is not a xen mechanism since UUID''s are not a concept exlusive to xen. The one caller in xl seems to be an

Changes since v1: - Fix a double-free bug introduced by v1, pointed out by Stefano where internal pointer was being passed back to caller from libxl_create_stubdom() 8<---------------------------------------------------------------------- Currently scratch variables allocated by libxl have the same lifetime as the context. While this is suitable for one off invocations of xl. It is not

Hi, Here are three small but important libxl/xl memory management patches: - libxl: xl mem-max et consortes must update static-max in xenstore too, - xl: Allow user to configure xl mem-set behavior, - xl: Improve xl documentation in regards to guest memory management. Daniel

Implement "rtc_timeoffset" and "localtime" options compatible as xm. rtc_timeoffset is the offset between host time and guest time. localtime means to specify whether the emulted RTC appears as UTC or is offset by the host.

libxl__domain_build_info_setdefault may be called several times, so rtc_timeoffset can''t be setted in it. Move rtc_timeoffset setting logic to libxl__build_pre.

Changes since v1: - Include nic,net2,vkb,vfb init functions --- This allows libxl users to get some sane default values for this complex set of structures. This is purely code movement and there are no functional changes except for a trivial error handling change in nic device init.

Hi Ian (and all), I recently came across a bug in xl autoballooning in Xen 4.2.2 that I found mentioned way back in May 2012. In a nutshell, I tried to create a new DomU with 1024M of memory. The Dom0 had 3100M free: # xl info | grep memory total_memory : 20479 free_memory : 3100 The guest template is very simple: # cat /etc/xen/template.vm name =

Coding style has recently been changed for libxl. The convenience macro LOG() has been introduced, and invocations of the old macro LIBXL__LOG() are to be replaced with it. Change occurences of the old macro to the new one in the functions qmp_handle_response() and qmp_handle_error_response(). The new macros need access to a local libxl__gc *gc, so add it as a parameter to both these functions,

I am just beginning to learn R. Please help. I have two matrices. One 20 columns by 16 rows represent student responses on a 20 question test. The second is 20 by 16 representing the correct responses 16 times. Subtracting one from the other should yield 0's if a response is correct. Yet Response minus Bigkey doesn't work. Documents indicate vectors should add and subtract, and

I was working on a teaching example, but came across this weird result: > q<-c(1.6,2.6, -3.4) > q [1] 1.6 2.6 -3.4 > sum(q) [1] 0.8 > sum(q)- 0.8 [1] 2.22044605e-16 Why is the result not precisely zero? Thanks! AT

I don't know if there is a way to do this in R but I want to subtract within the same column from different rows. I want to subtract c(r)-c(r-1) and continue down the column until they are all calculated and form another column. Again I don't know if R can do this but I thought I would ask. Thanks either way

I have a data frame with 2 columns, one for day and one for average. The day starts at 97 all the way to 279. I want to subtract day 98 average- day 97 average, then day99 average -day 98 average and so on down my list, creating another column with the subtracted results. I have: Day DailyAverage 1 97 0.6076782 2 98 0.7121478 3 99 0.8059347 4 100 0.9545806 5
