[libvirt] RFC: advertising graphics support (vnc, spice, sdl)
by Doug Goldstein 23 Oct '12

23 Oct '12

Currently consumers of libvirt's APIs must assume/attempt to define a VM that uses spice, vnc, or sdl without knowing if the actual hypervisor supports it. Obviously my discussion is very QEMU oriented but it would be good to leave expansion for the future. I was thinking that under the <guest> element for the capabilities we can add something like: <graphics> <spice/> <vnc/> <sdl/> </graphics> It would be at the same level as <arch> and <features>. But before I implemented this I wanted a sanity check if people think this is the best place or the best naming convention. Thanks. -- Doug Goldstein

[libvirt] [PATCH] qemu: Report errors from iohelper
by Michal Privoznik 23 Oct '12

23 Oct '12

Currently, we use iohelper when saving/restoring a domain. However, if there's some kind of error (like I/O) it is not propagated to libvirt. Since it is not qemu who is doing the actual write() it will not get error. The iohelper does. Therefore we should check for iohelper errors as it makes libvirt more user friendly. --- src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 7 ++++- src/util/virfile.c | 47 ++++++++++++++++++++++++++++++++++++++++++++++ src/util/virfile.h | 2 + 4 files changed, 55 insertions(+), 2 deletions(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 60f9c7f..26eb7b1 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1332,6 +1332,7 @@ virDomainListSnapshots; virFileLoopDeviceAssociate; virFileClose; virFileDirectFdFlag; +virFileWrapperFdCatchError; virFileWrapperFdClose; virFileWrapperFdFree; virFileWrapperFdNew; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 8af316f..c8e97cf 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2945,6 +2945,7 @@ endjob: if (rc < 0) VIR_WARN("Unable to resume guest CPUs after save failure"); } + virFileWrapperFdCatchError(wrapperFd); } if (qemuDomainObjEndAsyncJob(driver, vm) == 0) vm = NULL; @@ -3282,9 +3283,11 @@ doCoreDump(struct qemud_driver *driver, cleanup: VIR_FORCE_CLOSE(fd); - virFileWrapperFdFree(wrapperFd); - if (ret != 0) + if (ret != 0) { + virFileWrapperFdCatchError(wrapperFd); unlink(path); + } + virFileWrapperFdFree(wrapperFd); return ret; } diff --git a/src/util/virfile.c b/src/util/virfile.c index 5b00ead..4d7538e 100644 --- a/src/util/virfile.c +++ b/src/util/virfile.c @@ -135,6 +135,7 @@ virFileDirectFdFlag(void) * read-write is not supported, just a single direction. */ struct _virFileWrapperFd { virCommandPtr cmd; /* Child iohelper process to do the I/O. */ + int err_fd; /* FD to read stderr of @cmd */ }; #ifndef WIN32 @@ -229,6 +230,14 @@ virFileWrapperFdNew(int *fd, const char *name, unsigned int flags) virCommandAddArg(ret->cmd, "0"); } + /* In order to catch iohelper stderr, we must: + * - pass a FD to virCommand (-1 to auto-allocate one) + * - change iohelper's env so virLog functions print to stderr + */ + ret->err_fd = -1; + virCommandSetErrorFD(ret->cmd, &ret->err_fd); + virCommandAddEnvPair(ret->cmd, "LIBVIRT_LOG_OUTPUTS", "1:stderr"); + if (virCommandRunAsync(ret->cmd, NULL) < 0) goto error; @@ -280,6 +289,42 @@ virFileWrapperFdClose(virFileWrapperFdPtr wfd) return virCommandWait(wfd->cmd, NULL); } + +/** + * virFileWrapperFdCatchError: + * @wfd: fd wrapper, or NULL + * + * Read the stderr of iohelper and VIR_WARN() about it. + */ +void +virFileWrapperFdCatchError(virFileWrapperFdPtr wfd) +{ + char *err = NULL; + char ebuf[1024]; + size_t nread = 0; + size_t err_size = 0; + + if (!wfd) + return; + + while ((nread = saferead(wfd->err_fd, ebuf, sizeof(ebuf)))) { + if (VIR_REALLOC_N(err, err_size + nread + 1) < 0) { + virReportOOMError(); + goto cleanup; + } + memcpy(err + err_size, ebuf, nread); + err_size += nread; + err[err_size] = '\0'; + } + + if (err) + VIR_WARN("iohelper reports: %s", err); + +cleanup: + VIR_FREE(err); +} + + /** * virFileWrapperFdFree: * @wfd: fd wrapper, or NULL @@ -295,6 +340,8 @@ virFileWrapperFdFree(virFileWrapperFdPtr wfd) if (!wfd) return; + VIR_FORCE_CLOSE(wfd->err_fd); + virCommandFree(wfd->cmd); VIR_FREE(wfd); } diff --git a/src/util/virfile.h b/src/util/virfile.h index c885b73..80daf86 100644 --- a/src/util/virfile.h +++ b/src/util/virfile.h @@ -90,6 +90,8 @@ int virFileWrapperFdClose(virFileWrapperFdPtr dfd); void virFileWrapperFdFree(virFileWrapperFdPtr dfd); +void virFileWrapperFdCatchError(virFileWrapperFdPtr dfd); + int virFileLock(int fd, bool shared, off_t start, off_t len); int virFileUnlock(int fd, off_t start, off_t len); -- 1.7.8.6

[libvirt] [PATCH v2] put dnsmasq parameters into a file instead of the command line
by Gene Czarcinski 23 Oct '12

23 Oct '12

This patch changes the way parameters are passed to dnsmasq. They are put into a conf-file instead of being on the dnsmasq command line. **NOTE ** This has updated the related tests for the new data format, etc. **NOTE** This patch does NOT include specifying interface= The command line now contains --conf-file=<filename> and a new parameter --conf-dir=<directoryname> has been added. The new file and directory are put in the same directory as the leases file. --- .gnulib | 2 +- src/network/bridge_driver.c | 179 ++++++++++++++------- src/network/bridge_driver.h | 8 +-

[libvirt] Need new maintainer for libvirt on MacPorts
by Justin Clift 23 Oct '12

23 Oct '12

Hi all, Is anyone up for being the new owner/maintainer for libvirt on OSX MacPorts? The MacPorts guys have pinged us, suggesting we update the libvirt port there to something recent: https://trac.macports.org/ticket/36691 I'm still very engaged on the Homebrew side, but have next to no interest in MacPorts so am looking to pass it on. :) ? Regards and best wishes, Justin Clift -- Aeolus Community Manager http://www.aeolusproject.org

[libvirt] patch option needs clarification
by Gene Czarcinski 23 Oct '12

23 Oct '12

I am pretty much complete creating a patch which changes how dnsmasq is started by moving the command line parameters into a conf file. This new file is placed into the same directory and the lease file. The test for the command line arguments now checks the contents of the conf-file and there is no longer any tests for the command line parameters which are now two. The first command line parameter is (naturally) --conf-file=<filename>. The second parameter adds new functionality and is --conf-dir=<directory>. This directory is placed into the same directory as the conf-file and the lease file. The name of this directory is "<net-name>.d". This was added to make testing/debugging of new dnsmasq options easier since it no longer requires rebuilding the binaries. This is also useful for adding log-dhcp and/or log-queries for a specific network. Now the option question. I can submit the patch assuming the my previously submitted patch to add --interface to the command line has been applied or I can assume that it has not been applied. In either case, the new code adds a interface=<dev-name> to the conf-file. All development and testing was done with 0.10.2 libvirt src.rpm on Fedora 17. The patch will be submitted based on git.

[libvirt] [PATCHv2] Fix disabling of apparmor/selinux security drivers
by Christophe Fergeau 23 Oct '12

23 Oct '12

When using --without-$name --without-secdriver-$name with $name being selinux or apparmor, configure will fail saying that AppArmor/SELinux development package must be installed. This is caused by a small bug in --with-secdriver-$name handling in configure.ac which treats --without-secdriver-$name when $name as if the user had requested to enable $name when $name couldn't be detected on the system. This commit also makes sure the detection checks for disabled secdrivers do not needlessly get run, especially as this could cause an error as well in --with-$name --without-secdriver-$name situations. --- configure.ac | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/configure.ac b/configure.ac index 8810efd..5ea3bc2 100644 --- a/configure.ac +++ b/configure.ac @@ -1493,10 +1493,11 @@ AC_ARG_WITH([secdriver-selinux], if test "$with_selinux" != "yes" ; then if test "$with_secdriver_selinux" = "check" ; then with_secdriver_selinux=no - elif test "$with_secdriver_selinux" = "yes"; then + fi + if test "$with_secdriver_selinux" != "no"; then AC_MSG_ERROR([You must install the libselinux development package and enable SELinux with the --with-selinux=yes in order to compile libvirt --with-secdriver-selinux=yes]) fi -else +elif test "$with_secdriver_selinux" != "no"; then old_cflags="$CFLAGS" old_libs="$LIBS" CFLAGS="$CFLAGS $SELINUX_CFLAGS" @@ -1571,10 +1572,11 @@ AC_ARG_WITH([secdriver-apparmor], if test "$with_apparmor" != "yes" ; then if test "$with_secdriver_apparmor" = "check" ; then with_secdriver_apparmor=no - else + fi + if test "$with_secdriver_apparmor" != "no" ; then AC_MSG_ERROR([You must install the AppArmor development package in order to compile libvirt]) fi -else +elif test "with_secdriver_apparmor" != "no" ; then old_cflags="$CFLAGS" old_libs="$LIBS" CFLAGS="$CFLAGS $APPARMOR_CFLAGS" -- 1.7.12.1

[libvirt] vbox Hypervisor driver not found
by p.venkatasrinivas＠tcs.com 23 Oct '12

Hi, I installed Libvirt. We need virtualbox support for libvirt. But we are unable to see the vbox option in virt-manager. How we can find vbox hypervisor driver? And also we already compiled libvirt with vbox option.(--with-vbox). But that didn't work. And also when we are creating the new virtual machine through virt-manager we are getting the following error: internal error cannot parse QEMU version number in "" Can you please suggest on this what we need to do as soon as possible? Thanks in advance.
