[libvirt] [PATCH] conf/qemu: enforce NUMA nodes only for x86 memory hotplug
by Nikunj A Dadhania 15 Sep '15

15 Sep '15

libvirt enforces at least one NUMA node for memory hotplug support on all architectures. While it might be required for some x86 guest, PowerPC can hotplug memory on non-NUMA system. The generic checks are replaced with arch specific check and xml validation too does not enforce "node" for non-x86 arch.

[libvirt] [PATCH] target-i386: Enable "check" mode by default
by Eduardo Habkost 09 Sep '15

09 Sep '15

Current default behavior of QEMU is to silently disable features that are not supported by the host when a CPU model is requested in the command-line. This means that in addition to risking breaking guest ABI by default, we are silent about it. I would like to enable "enforce" by default, but this can easily break existing production systems because of the way libvirt makes assumptions about CPU models today (this will change in the future, once QEMU provide a proper interface for checking if a CPU model is runnable). But there's no reason we should be silent about it. So, change target-i386 to enable "check" mode by default so at least we have some warning printed to stderr (and hopefully logged somewhere) when QEMU disables a feature that is not supported by the host system.

[libvirt] [PATCHv3 0/2] Added waiting for DAD to finish for bridge address.
by Maxim Perevedentsev 07 Sep '15

07 Sep '15

This is a fix for commit db488c79173b240459c7754f38c3c6af9b432970 dnsmasq main process which is relied on when waiting for DAD to complete exits without actually waiting for DAD. This is dnsmasq daemon's task. It seems to be a race that DAD finished before dnsmasq main process exited. The above commit needs the execution to block until DAD finishes for bridge IPv6 address because then it closes dummy tap device. Thus we need to ensure this ourselves. So we periodically poll the kernel using netlink and check whether there are any IPv6 addresses assigned to bridge which have 'tentative' state. After DAD is finished, execution continues. I guess that is what dnsmasq was assumed to do. We use netlink to dump information about existing IPv6 addresses. Netlink's response is a multi-part message. Unfortunately, the current implementation of virNetlink treats such messages as faulty and throws an error. So the patch 2/2 adds multi-part nelink response support. Update v2: fixed syntax. Update v3: moved to virnetdev. Maxim Perevedentsev (2): network: added waiting for DAD to finish for bridge address.

[libvirt] [PATCH libvirt master] interface type: add udp socket support
by Jonathan Toppins 05 Sep '15

05 Sep '15

Adds a new interface type using UDP sockets, this seems only applicable to QEMU but have edited tree-wide to support the new interface type. The interface type required the addition of a "destaddr" (destination address), this then maps into the following xml and qemu call. <interface type='udp'> <mac address='52:54:00:5c:67:56'/> <source address='127.0.0.1' port='11112'/> <model type='virtio'/> <dest address="127.0.0.1' port='22222'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> ... QEMU call: -netdev socket,udp=127.0.0.1:22222,localaddr=127.0.0.1:11112 Notice the xml "source" entry becomes the "localaddr" for the qemu call. reference: http://lists.gnu.org/archive/html/qemu-devel/2011-11/msg00629.html Signed-off-by: Jonathan Toppins <jtoppins(a)cumulusnetworks.com> --- docs/formatdomain.html.in | 17 ++++++++++++ src/conf/domain_conf.c | 56 +++++++++++++++++++++++++++++++++++++--- src/conf/domain_conf.h | 3 +++ src/conf/netdev_bandwidth_conf.h | 1 + src/libxl/libxl_conf.c | 1 + src/lxc/lxc_controller.c | 1 + src/lxc/lxc_process.c | 1 + src/qemu/qemu_command.c | 12 +++++++++ src/qemu/qemu_hotplug.c | 1 + src/qemu/qemu_interface.c | 2 ++ src/uml/uml_conf.c | 5 ++++ src/xenconfig/xen_sxpr.c | 1 + tools/virsh-domain.c | 1 + 13 files changed, 99 insertions(+), 3 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index c0a265a..95f7f5d 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4165,6 +4165,23 @@ </devices> ...</pre> + <h5><a name="elementsNICSUDP">UDP unicast tunnel</a></h5> + + <p> + A UDP unicast architecture provides a virtual network which enables + connections between Qemu instances using Qemu's UDP infrastructure.</p> + +<pre> + ... + <devices> + <interface type='udp'> + <mac address='52:54:00:22:c9:42'/> + <source address='127.0.0.1' port='11115'/> + <dest address='127.0.0.1' port='11116'/> + </interface> + </devices> + ...</pre> + <h5><a name="elementsNICSModel">Setting the NIC model</a></h5> <pre> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index e4114f8..11961ea 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -385,7 +385,8 @@ VIR_ENUM_IMPL(virDomainNet, VIR_DOMAIN_NET_TYPE_LAST, "bridge", "internal", "direct", - "hostdev") + "hostdev", + "udp") VIR_ENUM_IMPL(virDomainNetBackend, VIR_DOMAIN_NET_BACKEND_TYPE_LAST, "default", @@ -1629,7 +1630,9 @@ void virDomainNetDefFree(virDomainNetDefPtr def) case VIR_DOMAIN_NET_TYPE_SERVER: case VIR_DOMAIN_NET_TYPE_CLIENT: case VIR_DOMAIN_NET_TYPE_MCAST: + case VIR_DOMAIN_NET_TYPE_UDP: VIR_FREE(def->data.socket.address);

[libvirt] [RFC PATCH 0/3] Implement mockup capabilities cache in QEMU tests
by Pavel Fedin 04 Sep '15

04 Sep '15

Since commit e8d55172544c1fafe31a9e09346bdebca4f0d6f9 qemu driver checks emulator capabilities during domain XML post-parse. However, test suite does not initialize it, therefore a condition to skip all checks if there is no cache supplied was added. This is actually a hack, whose sole purpose is to make existing test suite working. Additionally, it prevents from writing new tests for this particular functionality. This series attempts to solve this problem by implementing proper cache mockup in test suite. The main idea is to create a cache in standard way and put there a pre-defined capabilities set (which tests already have). The main problem here is to know emulator binary name, which is contained in the source XML. However, we have to create our cache before reading the XML. The simplest way to resolve this is to assume particular binary name from test name. Currently tests which assume cross-architecture binary are all prefixed with the architecture name (with one exception of "keywrap" tests which all assume /usr/bin/qemu-system-s390x and do not have "s390-" prefix in their name). This scheme works fine, unless we use "native" emulator binary. Here we have a mess. Most newer tests use /usr/bin/qemu, however there is a large number of tests which use /usr/libexec/qemu-kvm or /usr/bin/kvm (i guess these are leftovers from the epoch when qemu-kvm was a separate fork of qemu). This is currently not handled in any way, and these tests may report errors due to missing binaries (because virQEMUCapsCacheLookup() attempts to populate the cache automatically by querying the binary if not already known). There are several possible ways to resolve this: a) Add all possible names as aliases for /usr/bin/qemu b) Forbid to use oldstyle names at all in these tests c) Declare some prefix like "kvm-" for those tests who want to use /usr/libexec/qemu-kvm. Again, this would ban /usr/bin/kvm and /usr/bin/qemu-kvm (if not using aliases like in (b) d) Hardcode (optional) emulator name per test. IMHO a bad idea because number of tests is huge. e) Do some preparsing of the XML and extract binary name from it. Again, i disliked it for not being simple enough. I also thought about an alternate implementation which would patch postParseCallback and insert own function there which builds a cache. At this point binary name is already known from the XML. However, such a design looks like an ugly hack by itself, so i stopped going in this direction. Comments and opinions are welcome.
