[Libvir] [PATCH] Enhanced stats for fullvirt domains
by Richard W.M. Jones 14 Nov '07

14 Nov '07

This patch does a couple of primary things: Firstly it allows you to use "hda", etc. as a path for getting block device stats from fullvirt domains. Secondly it separates out the stats code into a new file called 'stats_linux.c'. The reasoning behind the name is that this code can be shared between Xen & QEMU, and that the code is Linux-specific (it never worked on Solaris, but now this is explicit). I anticipate a 'stats_solaris.c' file once I can get Solaris + Xen going on a test machine. Also we try to detect the case where the block dev stats of a fullvirt domain are stuck at 0 -- caused by there being no frontend driver connected. We detect the condition by a query to xenstore. XENVBD_MAJOR is no longer hard-coded if we can get it instead from Linux header files. This patch adds bytes written/read to block devices for Xen PV domains if available. This also corrects a bug where stats from xvdb, xvdc, .. could not be read out because the device number was being miscalculated.

[Libvir] [PATCH] Fix xen://hostname URIs with no trailing slash
by Richard W.M. Jones 14 Nov '07

14 Nov '07

It turns out that xmlParseURI gives an error if asked to parse the string "xen://". This string arises because after a URI such as "xen://hostname" has been stripped of its server field, it becomes "xen://" on the remote end of the connection, and the failure of xmlParseURI causes the whole connection to fail. I'm not sure of the best way to fix it. The attached patch is a semi-hack which at least allows xen://hostname to work. It's not a problem for qemu because these URIs should always contain a path. Nor for test for the same reason. Not sure about OpenVZ.

[Libvir] [PATCH] parse URI once in src/libvirt.c, pass parsed URI to all drivers
by Richard W.M. Jones 14 Nov '07

14 Nov '07

The basic change here is that the virDrvOpen call (the internal "open" call for drivers) now takes the parsed xmlURIPtr instead of the raw name string. typedef virDrvOpenStatus (*virDrvOpen) (virConnectPtr conn, - const char *name, + xmlURIPtr uri, int flags); So we avoid the redundant URI parsing which was going on inside all the drivers, and also the ad-hoc "does-it-look-like-a-URI" string comparisons. That's straightforward enough except that all of the drivers were saving the name string in their private data so that they could implement the virConnectGetURI call. I've changed this so that the name is copied and saved in the main virConnect structure, and virConnectGetURI will return that unless the driver wants to override it. You need another patch (coming shortly) to allow URIs like xen://localhost (without the trailing slash) to work, which was IIRC the original point of this discussion.

[Libvir] [PATCH] Parse integers more carefully, cont'd.
by Jim Meyering 13 Nov '07

13 Nov '07

Here's part two in the strtol fix-up series: Parse integers more carefully, cont'd. * qemud/qemud.c: Replace uses of strtol with uses of xstrtol_i. Avoid overflow for very large --timeout=N values. * src/nodeinfo.c: In linuxNodeInfoMemPopulate and linuxNodeInfoCPUPopulate, use xstrtol_i rather than strtol. Unlike in qemud.c, here we allow trailing "isspace", and in the case of "cpuinfo cpu MHz", also allow a "." terminator, since we ignore the decimal and any following digits. * src/internal.h: Define xstrtol_iu, too.

[Libvir] [PATCH] Make qemud's install-init rule work in a non-srcdir build.
by Jim Meyering 13 Nov '07

13 Nov '07

When building from other than the source directory, several things currently fail. This one fails because $(srcdir)/libvirtd.init doesn't exist. The libvirtd.init file we want to install is the one just built, in the current directory. Here's the fix: Make qemud's install-init rule work in a non-srcdir build. * qemud/Makefile.am: In the install-init, remove an unneeded $(srcdir)/ prefix. --- qemud/Makefile.am | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/qemud/Makefile.am b/qemud/Makefile.am index 506fde5..3da6265 100644 --- a/qemud/Makefile.am +++ b/qemud/Makefile.am @@ -95,7 +95,7 @@ remote_dispatch_proc_switch.h: remote_generate_stubs.pl remote_protocol.x if LIBVIRT_INIT_SCRIPTS_RED_HAT install-init: libvirtd.init mkdir -p $(DESTDIR)$(sysconfdir)/rc.d/init.d - $(INSTALL_SCRIPT) $(srcdir)/libvirtd.init $(DESTDIR)$(sysconfdir)/rc.d/init.d/libvirtd + $(INSTALL_SCRIPT) libvirtd.init $(DESTDIR)$(sysconfdir)/rc.d/init.d/libvirtd mkdir -p $(DESTDIR)$(sysconfdir)/sysconfig $(INSTALL_SCRIPT) $(srcdir)/libvirtd.sysconf $(DESTDIR)$(sysconfdir)/sysconfig/libvirtd -- 1.5.3.5.643.g40e25

[Libvir] bug #384300 - libvirt package for Debian
by Richard W.M. Jones 13 Nov '07

13 Nov '07

This is a libvirt package for Debian. It's derived from the Ubuntu libvirt package, rebuilt for Debian testing. I'm not the greatest Debian packager in the world, so any comments / feedback are welcome. The previous patch to the base Xen package is also required before this can be built.

[Libvir] [PATCH] bug #402249 - include <xen/*.h> header files
by Richard W.M. Jones 13 Nov '07

13 Nov '07

When you build Xen from source, the "make install" rule installs extra header files such as <xen/xen.h> and <xen/dom0_ops.h> which are all required for building libvirt. However the Debian package doesn't run the install rule, but instead runs (effectively) "make -C tools install" and that only installs a partial set of header files. In particular none of the vital public Xen header files are installed, making it impossible to build libvirt, and probably other stuff as well. This patch fixes that by copying the required files by hand: http://et.redhat.com/~rjones/debian-libvirt/debian-xen-includes.patch (It is similar to what the Fedora RPM does, faced with the same situation). There is a bug which is somewhat related to this issue: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=402249 Rich. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
