[libvirt] [PATCH] Add automatic generation of a todo item page
by Daniel P. Berrange 23 Sep '10

23 Sep '10

This adds a script to generate the todo item page from bugzilla. This requires a valid username+password for bugzilla, so it is intended that this only be run on the libvirt.org website via cron.

[libvirt] [PATCH] Enable support for nested SVM
by Daniel P. Berrange 23 Sep '10

23 Sep '10

This enables support for nested SVM using the regular CPU model/features block. If the CPU model or features include 'svm' or 'vmx', then the '-enable-nesting' flag will be added to the QEMU command line. Several of the models already include svm support, but QEMU was just masking out the svm bit silently. So this will enable SVM on such models * src/qemu/qemu_conf.h: flag for -enable-nesting * src/qemu/qemu_conf.c: Use -enable-nesting if VMX or SVM are in the CPUID * src/cpu/cpu.h, src/cpu/cpu.c: API to check for a named feature * src/cpu/cpu_x86.c: x86 impl of feature check * src/libvirt_private.syms: Add cpuHasFeature --- src/cpu/cpu.c | 24 ++++++++++++++++++++++ src/cpu/cpu.h | 12 +++++++++++ src/cpu/cpu_x86.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++ src/libvirt_private.syms | 1 + src/qemu/qemu_conf.c | 19 +++++++++++++++- src/qemu/qemu_conf.h | 1 + 6 files changed, 105 insertions(+), 2 deletions(-) diff --git a/src/cpu/cpu.c b/src/cpu/cpu.c index def6974..c7a282e 100644 --- a/src/cpu/cpu.c +++ b/src/cpu/cpu.c @@ -424,3 +424,27 @@ cpuUpdate(virCPUDefPtr guest, return driver->update(guest, host);

[libvirt] [PATCH] nwfilter: enable bridge netfilter calls via proc filesystem
by Stefan Berger 23 Sep '10

23 Sep '10

On a recent installation of FC13, the filtering of IP/IPv6 using iptables/ip6tables traffic did not work since the proc filesystem entries /proc/sys/net/bridge/bridge-nf-call-iptables and /proc/sys/net/bridge/bridge-nf-call-ip6tables contained a zero each and no traffic went into the FORWARD chain. The patch below makes sure that if iptables or ip6tables are being used by the nwfilter driver that a '1' is written into the relevant proc filesystem entry so that the traffic goes into the FORWARD chain.

[libvirt] [RFC PATCH] maint: update to latest gnulib
by Eric Blake 23 Sep '10

23 Sep '10

* .gnulib: Update to latest. * bootstrap.conf (gnulib_modules): Add new termios module. (gnulib_tool_option_extras): Make libtool usage explicit. * src/util/util.c (includes): Gnulib now guarantees termios.h. * bootstrap: Resync from gnulib. --- On IRC, hallyn_ pointed out that libvirt doesn't build with the latest gnulib. This fixes that situation. However, until http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/23111/focus=23241 is fixed upstream, this patch points .gnulib at a commit that is only in my repository; hence marking it as an RFC (I can't push this until I rebase it to point .gnulib to a public commit that works). .gnulib | 2 +- bootstrap | 11 +++++++---- bootstrap.conf | 2 ++ src/util/util.c | 4 +--- 4 files changed, 11 insertions(+), 8 deletions(-) * .gnulib 7ba06c8...d2a65f2 (174): > termios: relax license > threadlib: Allow the package to change the default to 'no'. > autoupdate > Fix endless loop in mbmemcasecoll. > Tests for module 'memcoll'. > memcoll, xmemcoll: Clarify size vs. length. > Tests for module 'memcasecmp'. > pthread: add to system <pthread.h> instead of replacing it all, for MacOS > net_if: enhance tests > Add ChangeLog entry for last commit. > Manual: improve out-of-memory documentation. > autoupdate > Add ChangeLog entry. > Use src/ not lib/ as root of source in example Makefile.am code. > Set cut_dir properly, and add mode line for Emacs. > Set cut_dir properly, and add mode line for Emacs. > Make Makefile.am example code more cut-and-paste friendly. > New module to test <net/if.h> interfaces. > pthread: add pthread_spin_destroy > gnulib-tool: Fix --help output. > maint.mk: avoid unexpanded \n in two diagnostics > netinet_in: Doc tweak. > init.sh: correct an outdated comment > init.sh: don't let an ephemeral "*.exe" make us skip all dir entries > mirbsd: add some more support > tests: fix unportable assumption on sys/wait.h > init.sh: accomodate directory with no .exes > tests: avoid compiler warning > fdutimens, fdutimensat: update signature, again > Take over the maintenance of some older macros from Autoconf. > fdutimensat: drop atflag validation > unlockpt: Fix declaration within GNULIB_POSIXCHECK. > login_tty: Fix detection of function on FreeBSD, OpenBSD, NetBSD. > login_tty: Make the replacement code work on BSD systems. > login_tty: Stricter unit test. > New module 'tcgetsid'. > Tests for module 'termios'. > New module 'termios'. > fdutimensat: add an atflag parameter > Fix typos in comments. > Fix typo in last commit. > stdlib: clarify MirBSD WEXITSTATUS bug > stdlib: work around MirBSD WEXITSTATUS bug > docs: mention MacOS issue with WEXITSTATUS(constant) > strnlen: add tests > unistr/base: Avoid link errors when module 'libunistring' is also used. > test-rawmemchr: make more robust > memchr: detect glibc Alpha bug > fts, getcwd, glob: audit for dirfd returning -1 > float: fix broken MirBSD header > fts: use O_NOFOLLOW to avoid race condition when opening a directory > fdopendir: preserve argument fd before returning > regex: Pass the system regex if its only problem is 32-bit regoff_t. > fts: don't operate on an invalid file descriptor after failed dup > savedir: add streamsavedir, deprecate fdsavedir > autoupdate > langinfo: Fix last commit. > relocatable-prog-wrapper: Fix compilation failure due to O_EXEC. > Improve NEWS entry. > * NEWS: Document recent changes to fcntl-h. > fcntl-h: define O_CLOEXEC and O_EXEC if not defined; use new defines > langinfo, nl_langinfo: Fix for IRIX 5.3. > pty, readutmp: Fix for FreeBSD 8.0 and OpenBSD 4.6. > strsignal: work around NetBSD bug > gnulib-tool: work with NetBSD /bin/sh > autoupdate > gnulib-tool: Avoid stderr output on IRIX related to 'alias', 'unalias'. > init.sh: penalize a set-x-impaired shell; don't disqualify it > unsetenv: fix OpenBSD bug > strtod: work around IRIX 6.5 bug > autoupdate > maint: fix ChangeLog ordering > getopt: optimize previous patch > init.sh: disqualify shells for which set -x corrupts stderr > gnulib-tool: Avoid stderr output on IRIX related to 'alias', 'unalias'. > Fix formatting of ChangeLog entry. > regex documentation update from Reuben Thomas <rrt(a)sc3d.org>, 20 Aug 2010 12:04:39 +0100 > regex documentation update from Reuben Thomas <rrt(a)sc3d.org>, 20 Aug 2010 12:04:39 +0100 > getopt: handle POSIXLY_CORRECT set but not exported > gnulib-tool: Highlight the changed options. > update from texinfo > doc tweaks > uniwidth/width: Update comment. > isinf, isnan: Relax license. > gnulib-tool: Help migration from --import to --add-import or --update. > Update doc about gnulib-tool. > gnulib-tool: Change --import.
