[libvirt] [PATCH] qemu: Introduce inactive PCI device list
by Osier Yang 13 Jan '12

13 Jan '12

pciTrySecondaryBusReset checks if there is active device on the same bus, however, qemu driver doesn't maintain an effective list for the inactive devices, and it passes meaningless argment for parameter "inactiveDevs". e.g. (qemuPrepareHostdevPCIDevices) if (!(pcidevs = qemuGetPciHostDeviceList(hostdevs, nhostdevs))) return -1; ...skipped... if (pciResetDevice(dev, driver->activePciHostdevs, pcidevs) < 0) goto reattachdevs; NB, the "pcidevs" used above are extracted from domain def, and thus one won't be able to attach a device of which bus has other device even detached from host (nodedev-detach). To see more details of the problem: RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=773667 This patch is to resolve the problem by introduce an inactive PCI device list (just like qemu_driver->activePciHostdevs), and the whole logic is: * Add the device to inactive list when do nodedev-dettach * Remove the device from inactive list when do nodedev-reattach * Remove the device from inactive list when do attach-device (for not managed device) * Add the device to inactive list after detach-device, only if the device is not managed * Don't do any work if the device is managed, as it manages there is no gap in the whole workflow for another guest who wants to With above, we have sufficient inactive PCI device list, and thus we can use it for pciResetDevice. e.g.(qemuPrepareHostdevPCIDevices) if (pciResetDevice(dev, driver->activePciHostdevs, driver->inactivePciHostdevs) < 0) goto reattachdevs;

[libvirt] [PATCH] build: silence some compiler warnings from gnulib
by Eric Blake 12 Jan '12

12 Jan '12

Gnulib claims that there are some classes of warnings that are worth enabling during development, but where silencing those warnings causes code bloat that is not necessary in an optimized build. The code bloat to silence the warnings is only enabled by -Dlint. Follow the lead of coreutils in setting up -Dlint whenever full warnings are requested. * m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Add -Dlint, and move _FORTIFY_SOURCE to config.h instead of CFLAGS. --- In particular, see this gnulib thread, where Dan Berrange complained about a warning present on a mingw cross-compile: https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00184.html m4/virt-compile-warnings.m4 | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-) diff --git a/m4/virt-compile-warnings.m4 b/m4/virt-compile-warnings.m4 index ba388aa..3a428c3 100644 --- a/m4/virt-compile-warnings.m4 +++ b/m4/virt-compile-warnings.m4 @@ -100,8 +100,13 @@ AC_DEFUN([LIBVIRT_COMPILE_WARNINGS],[ gl_WARN_ADD([-Wframe-larger-than=4096]) dnl gl_WARN_ADD([-Wframe-larger-than=256]) + # Silence certain warnings in gnulib, and use improved glibc headers + AC_DEFINE([lint], [1], + [Define to 1 if the compiler is checking for lint.]) + AC_DEFINE([_FORTIFY_SOURCE], [2], + [enable compile-time and run-time bounds-checking, and some warnings]) + # Extra special flags - gl_WARN_ADD([-Wp,-D_FORTIFY_SOURCE=2]) dnl -fstack-protector stuff passes gl_WARN_ADD with gcc dnl on Mingw32, but fails when actually used case $host in -- 1.7.7.5

[libvirt] [PATCH v2 1/1] Added check for maximum number of vcpus exceeding topology limit
by Martin Kletzander 12 Jan '12

12 Jan '12

Earlier, when the number of vcpus was greater than the topology allowed, libvirt didn't raise an error and continued, resulting in running qemu with parameters making no sense. Even though qemu did not report any error itself, the number of vcpus was set to maximum allowed by the topology. --- v2: - Added check for topology specification src/conf/domain_conf.c | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 180dd2b..5e36270 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -8010,6 +8010,14 @@ static virDomainDefPtr virDomainDefParseXML(virCapsPtr caps, if (def->cpu == NULL) goto error; + if (def->cpu->sockets && + def->maxvcpus > + def->cpu->sockets * def->cpu->cores * def->cpu->threads) { + virDomainReportError(VIR_ERR_XML_DETAIL, "%s", + _("Maximum CPUs greater than topology limit")); + goto error; + } + if (def->cpu->cells_cpus > def->maxvcpus) { virDomainReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Number of CPUs in <numa> exceeds the" -- 1.7.3.4

[libvirt] ANNOUNCE: Release of libvirt-sandbox version 0.0.2
by Daniel P. Berrange 12 Jan '12

12 Jan '12

I pleased to announce the first public release of libvirt-sandbox, version 0.0.2 is now available for download ftp://libvirt.org/libvirt/sandbox/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) The libvirt-sandbox package provides an API layer on top of libvirt-gobject which facilitates the cration of application sandboxes using virtualization technology. An application sandbox is a virtual machine or container that runs a single application binary, directly from the host OS filesystem. In other words there is no separate guest operating system install to build or manager. At this point in time libvirt-sandbox can create sandboxes using either LXC or KVM, and should in theory be extendable to any libvirt driver. The first release is able to run simple command line based programs. While there is some GUI support, this is mostly unreliable / non-functional at this point in time, future releases will address this properly.

[libvirt] [PATCH] uuid: fix off-by-one
by Eric Blake 12 Jan '12

Detected by Coverity.
