[libvirt] [PATCH] Fix initialization of virIdentityPtr thread locals
by Daniel P. Berrange 21 Mar '13

21 Mar '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> Some code mistakenly called virIdentityOnceInit directly instead of virIdentityInitialize(). This meant that one-time initializer was run many times with predictably bad results.

[libvirt] [PATCH RFC 0/5] add support for scsi-generic for virtio-scsi
by Han Cheng 21 Mar '13

21 Mar '13

This patch series tried to implement the fifth part of Paolo's proposal: http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428 It is not completed. But it may for use. Needs some more works on: src/qemu/qemu_hostdev.c src/qemu/qemu_hotplug.c We may also need create src/util/virscsi.[hc] like src/util/vir(pci|usb).[hc], add sg* to nodedev tree and some others. As scsi hostdev needs -drive and -device like disk. There are two approaches: a) build a disk then use the disk related functions, b) create new function for it. I chose the last one as it is clearer and easier. But this may create some redundant codes. Any ideas?

[libvirt] [PATCH] Fix linkage of virt-aa-helper with numa library
by Daniel P. Berrange 21 Mar '13

21 Mar '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The recent commit moved some of the use of libnuma out of the driver code, and into src/util/. It did not, however, update libvirt_util.la to link against libnuma. This caused linkage failure with virt-aa-helper, since nothing else caused libnuma to be pulled onto the linker command line. The fix removes all reference to NUMACTL_LIBS/CFLAGS from the various modules in src/Makefile.am and just adds them to the libvirt_util.la module, which everything else depends on. Technically a build-breaker fix, but wanted to wait for feedback on this Signed-off-by: Daniel P.

[libvirt] [PATCH] qemu: Add the new disk src into shared disk table when updating disk
by Osier Yang 21 Mar '13

21 Mar '13

We should record the new disk src in the shared disk table for updating disk (CD-ROM or Floppy) API. Fortunately, we only allow to update the disk source now, otherwise we might also want to set the unpriv_sgio setting. --- src/qemu/qemu_driver.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 9cd9e44..d0d2b9e 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6067,6 +6067,10 @@ qemuDomainChangeDiskMediaLive(virDomainObjPtr vm, } dev->data.disk = tmp; + /* Add the new disk src into shared disk hash table */ + if (qemuAddSharedDisk(driver, dev->data.disk, vm->def->name) < 0) + goto end; + ret = qemuDomainChangeEjectableMedia(driver, vm, disk, orig_disk, force); if (ret == 0) { dev->data.disk = NULL; -- 1.7.7.6
