[libvirt] [PATCH v2] libvirtd: Increase NL buffer size for lots of interface
by Leno Hou 11 Jan '16

1. When switching CPUs to offline/online in a system more than 128 cpus 2. When using virsh to destroy domain in a system with more interface All of above happens nl_recv returned with error: No buffer space available. This patch sets the socket buffer size to 128K and turns on message peeking for nl_recv,as this would solve this problem totally and permanetly.

[libvirt] [PATCH] Unify int types handling in protocol files
by Roman Bogorodskiy 10 Jan '16

10 Jan '16

From: Jasper Lievisse Adriaanse <jasper(a)openbsd.org> Some of the protocol files already include handing of the missing int types such as xdr_uint64_t, some don't. To fix it everywhere, move out of the appropriate defines to internal.h and include it whenever needed.

[libvirt] [PATCH] examples: Use one top level makefile
by Cole Robinson 10 Jan '16

10 Jan '16

Using one Makefile per example subdirectory essentially serializes 'make' calls. Convert to one example/Makefile that builds and distributes all the subdir files. This reduces example/ rebuild time from about 5.8 seconds to 1.5 seconds on my machine. One slight difference is that we no longer ship Makefile.am with the examples in the rpm. This was virtually useless anyways since the Makefile was very specific to libvirt infrastructure, so wasn't generically reusable anyways.

[libvirt] Hot plug multi function PCI devices
by Ziviani . 08 Jan '16

08 Jan '16

Hello list! I'm new here and interested in hot-plug multi-function PCI devices. Basically I'd like to know why Libvirt does not support it. I've been through the archives and basically found this thread: https://www.redhat.com/archives/libvir-list/2011-May/msg00457.html But Qemu seems to handle it accordingly: virsh qemu-monitor-command --hmp fedora-23 'device_add vfio-pci,host=00:16.0,addr=08.0' virsh qemu-monitor-command --hmp fedora-23 'device_add vfio-pci,host=00:16.3,addr=08.3' GUEST: # lspci (snip) 00:08.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04) 00:08.3 Serial controller: Intel Corporation 8 Series HECI KT (rev 04) However, using Libvirt: % virsh attach-device fedora-23 pci_0000_00_16_0.xml --live Device attached successfully % virsh attach-device fedora-23 pci_0000_00_16_3.xml --live error: Failed to attach device from pci_0000_00_16_3.xml error: internal error: Only PCI device addresses with function=0 are supported I made some changes on domain_addr.c[1] for testing and it worked.

Thank you!

[libvirt] [PATCH v2] tests: Add newlines with VIR_TEST_REGENERATE_OUTPUT
by Cole Robinson 08 Jan '16

Since test files are formatted predictably nowadays, we can make VIR_TEST_REGENERATE_OUTPUT handle most cases for us with a simple replacement. test-wrap-argv.pl is still canon, but this bit makes it easier to confirm test output changes during active development. --- v2: Rebase on .git master tests/testutils.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/tests/testutils.c b/tests/testutils.c index 6645d61..0091fcd 100644 --- a/tests/testutils.c +++ b/tests/testutils.c @@ -469,10 +469,19 @@ virtTestDifferenceFullInternal(FILE *stream, actualStart = actual; actualEnd = actual + (strlen(actual)-1); - if (regenerate && virTestGetRegenerate() > 0) { + if (regenerate && (virTestGetRegenerate() > 0) && expectName && actual) { + char *regencontent; + + /* Try to properly indent qemu argv files */ + if (!(regencontent = virStringReplace(actual, " -", " \\\n-"))) + return -1; + if (expectName && actual && - virFileWriteStr(expectName, actual, 0666) < 0) + virFileWriteStr(expectName, regencontent, 0666) < 0) { + VIR_FREE(regencontent); return -1; + } + VIR_FREE(regencontent); } if (!virTestGetDebug()) -- 2.5.0
