[libvirt] [PATCH] conf: fix no error when set an unsupport string in ./devices/shmem/msi[@ioeventfd]
by Luyao Huang 11 May '15

11 May '15

https://bugzilla.redhat.com/show_bug.cgi?id=1220265 Pass the return value to an enum directly is not safe. When pass a invalid @ioeventfd and virTristateSwitchTypeFromString return -1 to def->msi.ioeventfd, and this value transform to 4294967295, so no error when the parse failed. Instead of define a int variable in virDomainShmemDefParseXML and use the new defined variable as transition variable. I think define ioeventfd as an 'int' variable will be better.

[libvirt] [PATCH] libxl: support vscsi
by Olaf Hering 09 May '15

09 May '15

This uses the API version of the proposed vscsi support in libxl (v4): http://lists.xenproject.org/archives/html/xen-devel/2015-04/msg01949.html Is there anything else that needs to be done in libvirt? Right now libvirt scsi support is very simple minded, no support at all to describe host devices with persistant names. This patch got very little runtime testing up to now...

[libvirt] [PATCH v2] caps: Fix regression defaulting to host arch
by Cole Robinson 09 May '15

09 May '15

My commit 747761a79 (v1.2.15 only) dropped this bit of logic when filling in a default arch in the XML: - /* First try to find one matching host arch */ - for (i = 0; i < caps->nguests; i++) { - if (caps->guests[i]->ostype == ostype) { - for (j = 0; j < caps->guests[i]->arch.ndomains; j++) { - if (caps->guests[i]->arch.domains[j]->type == domain && - caps->guests[i]->arch.id == caps->host.arch) - return caps->guests[i]->arch.id; - } - } - } That attempt to match host.arch is important, otherwise we end up defaulting to i686 on x86_64 host for KVM, which is not intended. Duplicate it in the centralized CapsLookup function. Additionally add some testcases that would have caught this. https://bugzilla.redhat.com/show_bug.cgi?id=1219191 --- v2: Tweak subject add test case for type=qemu as well src/conf/capabilities.c | 63 +++++++++++++++------- .../qemuxml2argv-default-kvm-host-arch.args | 4 ++ .../qemuxml2argv-default-kvm-host-arch.xml | 11 ++++ .../qemuxml2argv-default-qemu-host-arch.args | 4 ++ .../qemuxml2argv-default-qemu-host-arch.xml | 11 ++++ tests/qemuxml2argvtest.c | 2 + .../qemuxml2xmlout-default-kvm-host-arch.xml | 21 ++++++++ .../qemuxml2xmlout-default-qemu-host-arch.xml | 21 ++++++++ tests/qemuxml2xmltest.c | 2 + tests/testutilsqemu.c | 12 +++++ 10 files changed, 132 insertions(+), 19 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-default-kvm-host-arch.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-default-kvm-host-arch.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-default-qemu-host-arch.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-default-qemu-host-arch.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-default-kvm-host-arch.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-default-qemu-host-arch.xml diff --git a/src/conf/capabilities.c b/src/conf/capabilities.c index 922741f..c43bfb3 100644 --- a/src/conf/capabilities.c +++ b/src/conf/capabilities.c @@ -607,25 +607,13 @@ virCapsDomainDataCompare(virCapsGuestPtr guest, return true;
