[libvirt] [PATCH] maint: update to latest gnulib

Incorporates fixes for cross-compiling to mingw on rawhide, where gcc 5.1 changes detection of how to properly determine PRIdMAX. * .gnulib: Update to latest, for mingw. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I've missed the freeze for rc1, but confirmed that this update is rather minimal and should only affect mingw (in particular, it will fix cross-compilation failure under rawhide with gcc 5.1).

[libvirt] [PATCH] spec: fixes for recently introduced libxl conf files
by Jim Fehlig 01 Jun '15

01 Jun '15

Commit 198cc1d3 introduced libxl-lockd and libxl-sanlock config files but forgot to add them to the spec file. Follow-up commit 62b18d98 added the files to daemon-driver-libxl, but missed adding them to the daemon package when configuring libvirt --without-driver-modules. In addition, commit 62b18d98 added libxl-sanlock to daemon-driver-libxl, but it should be included in lock-sanlock when libvirt is configured --with-sanlock.

[libvirt] [PATCH v2] libxl: load on FreeBSD
by Roman Bogorodskiy 01 Jun '15

01 Jun '15

The libxl tries to check if it's running in dom0 by parsing /proc/xen/capabilities and if that fails it doesn't load. There's no procfs interface in Xen on FreeBSD, so this check always fails. In addition to checking procfs, check if /dev/xen/xenstored, that's enough to check if we're running in dom0 in FreeBSD case. --- src/libxl/libxl_driver.c | 42 ++++++++++++++++++++++-------------------- 1 file changed, 22 insertions(+), 20 deletions(-) diff --git a/src/libxl/libxl_driver.c b/src/libxl/libxl_driver.c index 12be816..fddafa1 100644 --- a/src/libxl/libxl_driver.c +++ b/src/libxl/libxl_driver.c @@ -74,6 +74,7 @@ VIR_LOG_INIT("libxl.libxl_driver"); #define LIBXL_CONFIG_FORMAT_SEXPR "xen-sxpr" #define HYPERVISOR_CAPABILITIES "/proc/xen/capabilities" +#define HYPERVISOR_XENSTORED "/dev/xen/xenstored" /* Number of Xen scheduler parameters */ #define XEN_SCHED_CREDIT_NPARAM 2 @@ -427,8 +428,6 @@ static bool libxlDriverShouldLoad(bool privileged) { bool ret = false; - int status; - char *output = NULL; /* Don't load if non-root */ if (!privileged) { @@ -436,24 +435,27 @@ libxlDriverShouldLoad(bool privileged) return ret; } - if (!virFileExists(HYPERVISOR_CAPABILITIES)) { - VIR_INFO("Disabling driver as " HYPERVISOR_CAPABILITIES - " does not exist"); - return ret; - } - /* - * Don't load if not running on a Xen control domain (dom0).

[libvirt] [PATCH v3 0/3] qemu: Deal with panic device on pSeries
by Andrea Bolognani 01 Jun '15

01 Jun '15

Currently, having the <panic> element in a domain XML prevents it from starting on pSeries. The error message in this case is not very accurate, and the first commit improves it. Since the guest firmware provides the same features as the pvpanic device for pSeries guests, the element should be allowed. The second commit implements this change. It being part of the firmware, the <panic> element should actually always be present in the domain XML: the third commit makes sure this is the case.

[libvirt] [PATCH] parallels: better support of volume based disks in containers
by Maxim Nestratov 01 Jun '15

01 Jun '15

It is possible to attach volumes to containers but since they are added they are reported erroneously as filesystems. It is fixed in this patch. And as soon as bus type has no meaning for containers we always report SATA for such disks. In case a container is created with the only disk based on physical volume we are expected to specify mount point to be able to boot from it, that is done in the patch.

[libvirt] [PATCH] check if console PTY is null before attempting to open
by Shivaprasad G Bhat 31 May '15

31 May '15

Console devices have their pty devices assigned when the qemu is actually started. The libvirt spends considerable amount of time to start the qemu if the guest has multiple passthrough devices. If time is spent during the hostdev preparation, someone attempts to open the console, the libvirt crashes in virChrdevLockFilePath().The patch attempts to fix the crash by adding a check before attempting to open.
