[libvirt] qemud/.libs/libvirtd?
Hi, I added some new code to libvirt.c, and recompile. However, when make install. qemud/.libs/libvirtd is installed but not qemud/libvirtd. Why? Looks like a bug? The problem is that qemud/libvirtd has my new code, but not qemud/.libs/libvirtd! So make install installs the old binary, which I dont know where it is from. (Perhaps from the first compilation?) I am not familiar with the autoconf Makefile, and cannot figure it out why it is working this way.

In the internal.h file I also #define pthread_sigmask to sigprocmask for scenarios where we don't have pthread - as per other usage.

[libvirt] Using Xen config files
I am trying to programmatically start Xen guest VMs (HVM) with libvirt (on
Fedora Core 8) and I'm having some trouble with it. I've included my code
below. Essentially, the domain seems to get created correctly but it
doesn't seem to run. I don't receive any error messages from the libvirt
functions but the VM does not get any CPU time (as shown with xm list).
[EMAIL PROTECTED] ~]$ xm list
NameID Mem VCPUs State
Time(s)
Domain-0 0 1462 2 r-
1313.5
fc8.conf 7 128 1 --
0.0
Can someone explain what I'm doing wrong here? I've tried to get this
working with linux and windows guests with the same results.
I've seen references on this mailing list to libvirt's ability to handle Xen
configuration files but I haven't seen anything in the API documentation or
public header files that refer to it. Is there a public interface to
specifying a configuration file?
Thanks

If you don't have them installed locally you will get validation error messages when building in docs and the output will diverge. The simplest solution for you is probably to make sure you have XHTML1 DTDs installed in your local XML catalog, which on RHEL/Fedora is as simple as having the package xhtml1-dtds installed on your machine(s). The patch enclosed adds detection for the XHTML1 dtds at runtime on the build machine, and should solve the problem of diverging docs, replace the XML validity warnings by a more general message and add the requirement when building the RPM. I guess this should solve the issue Yes, that did it for me. I like the warning message too; at least that gives someone a fighting chance of figuring out what to install if they do want to generate the docs for some reason.

Using errno here isn't always kosher, since _virExec doesn't always
preserve it when things go wrong (the ReportError call and close
calls after cleanup: can clobber errno).
But one can argue that it doesn't matter too much, since virExec
does diagnose each failure. However, that would suggest not
using errno upon virRun failure.

[libvirt] [PATCH] Don't list capabilities entries if emulators can't be accessed
The patch below fixes capabilities xml generation for
the qemu driver if the emulators aren't found in the
hardcoded paths. Current behavior will add a guest
entry for the emulator even if it does not exist, patch
fixes this to check that we actually have access.
This brings up another issue, that hardcoded paths
aren't exactly distro friendly. I'm not really familiar
with what options we have to allow specifying these
at build time (or something else). Anyone have an
idea?
Thanks,
Cole

Yes it does - this is what the virStorageBackendStablePath() method call does.
