...source, and I think I have got it working. Well, almost. I am using unmodified kernel of Fedora16 as my dom0 kernel. So this is what happened. I am able to boot into Xen, but the "xl info" failed with the standard error message mentioned in the tutorial. "libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to stat /var/run/xenstored.pid: No such file or directory cannot init xl context" I checked the xen common problems page, http://wiki.xensource.com/xenwiki/XenCommonProblems.html and did some troubleshooting.

...wnloaded Xen-4.1.1 from xen.org, compiled it, and installed it. I then compiled kernel 3.0.0 and added the hypervisor and dom0 kernel in a grub 2 entry. After booting, I executed "xl list," to confirm the hypervisor was running. I was greeted with this message: libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to stat /var/run/xenstored.pid: No such file or directory cannot init xl context I poked around and found there is a folder within /var/run called "xenstored" and I found there was no service called xenstored in /etc/init.d. There are the services I fo...

In general, xc_... functions return errno values or 0; xs_... functions return 0 or -1 (or some such) setting errno. * When

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before
