[libvirt] virtual switch - how to store state information
by Laine Stump 01 Jul '11

01 Jul '11

(If you already know about my work on putting a logical switch abstraction into libvirt's <network>, skip to part 2) INTRODUCTION =========== The rudimentary logical network switch capability I'm currently implementing (see https://bugzilla.redhat.com/show_bug.cgi?id=643947) is intended to allow a guest's interface XML to be free of any specific physical network device name, particularly in bridge and direct modes. It does this by expanding the definition of a libvirt <network> to include cases that merely describe a host-configured bridge, or a host interface (or pool of interfaces) that can be used by a guest in one of the 'direct' modes (bridge, private, vepa, or passthrough). It will also allow certain details of the guest's network connection to be configured by "portgroups" in the <network> definition (initially this will be limited to a portgroup containing a <virtualportprofile> and bandwidth limiting information). For example, in the past, a guest that wanted to connect to interface eth10 using the direct (aka 'macvtap') "vepa" mode would need to have this <interface> in its guest XML: <interface type='direct'> <mac address='52:54:00:34:a5:aa'/> <source dev='eth10' mode='vepa'/> <model type='virtio'/> <virtualport type='802.1Qbg'> <parameters managerid='33' typeid='89' typeidversion='3'/> </virtualport> </interface> With my new code, you can instead define a <network> with connections on several physical ethernets: <network> <name>test</name> <forward mode='vepa'> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> <interface dev='eth14'/> <interface dev='eth15'/> <interface dev='eth16'/> <interface dev='eth17'/> </forward> <portgroup name='accounting'> <virtualport type='802.1Qbg'> <parameters managerid='44' typeid='54' typeidversion='1'/> </virtualport> </portgroup> <portgroup name='engineering' default='yes'> <virtualport type='802.1Qbg'> <parameters managerid='33' typeid='89' typeidversion='3'/> </virtualport> </portgroup> </network> and then tell the domain's <interface> to get the information from the network: <interface type='network'> <mac address='52:54:00:34:a5:aa'/> <source network='test' portgroup='engineering'/> <model type='virtio'/> </interface> When libvirt sets up the interface connection, it will grab the config for network 'test', see that the forward mode is 'vepa', decide which physical ethernet to use, add in any extra stuff from the <portgroup>, and use that as the information for connection. In this manner, 1) it will remove the hardcoded device name from the domain config, making it possible to migrate the domain to other hardware, and 2) share a pool of physical devices over a group of domains. PROPOSAL ======== After I've determined which physical device to use, I need to save that information for as long as the domain is running, so that if libvirtd is restarted, it won't be lost (in some configs, only a single guest can use any particular netdev at a given time, so we want to be able to manage allocation of the devices without leaking any). My current idea is to save this in the domain <interface> XML that's put in the state directory, but make sure that it's never put into the XML returned by virsh dumpxml. What I'm thinking of is to add an <actual> subelement under <interface>, like this: <interface type='network'> <mac address='52:54:00:34:a5:aa'/> <source network='test' porgroup='engineering'/> <model type='virtio'/> <actual type='direct'/> <source dev='eth10' mode='vepa'/> <virtualport type='802.1Qbg'> <parameters managerid='33' typeid='89' typeidversion='3'/> </virtualport> </actual> </interface> This will be a private/internal thing used only within libvirt, however it does need to be stable, since it has to be understandable by a libvirtd that has started up while guests are running (eg during a libvirt upgrade). So I want to make sure I'm doing something reasonable. So, it is? Should <actual> contain *everything* from the parent interface, plus the items that are changed? Or should it contain only: * type attribute * source element * <bridge name=.../> (if applicable) * <virtualport> (and other items that might come from <portgroup> in the future (i.e. the things that have changed)? I *think* the answer is that it should just contain the items that have changed, and there should be a wrapper API around the virDomainNetDef object for retrieving things like type (if (def->actual) return def->actual.type; else return def->type; and similar) to make sure that all functions use the correct data.

[libvirt] [PATCHv2] build: consistently use CFLAGS
by Eric Blake 01 Jul '11

01 Jul '11

According to the automake manual, CPPFLAGS (aka INCLUDES, as spelled in automake 1.9.6) should only include -I, -D, and -U directives; more generic directives like -Wall belong in CFLAGS since they affect more phases of the build process.

[libvirt] [PATCH] Add test case for parsing JSON docs
by Daniel P. Berrange 30 Jun '11

30 Jun '11

While investigating some memory leaks it was unclear whether the JSON code correctly free'd all memory during parsing. Add a test case which can be run under valgrind to clearly demonstrate that the parser is leak free. * tests/Makefile.am: Add 'jsontest' * tests/jsontest.c: A few simple JSON parsing tests --- tests/Makefile.am | 14 +++++++ tests/jsontest.c | 111 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 125 insertions(+), 0 deletions(-) create mode 100644 tests/jsontest.c diff --git a/tests/Makefile.am b/tests/Makefile.am index 7db9d1f..3bde22e 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -14,6 +14,7 @@ INCLUDES = \ $(SASL_CFLAGS) \ $(SELINUX_CFLAGS) \ $(APPARMOR_CFLAGS) \ + $(YAJL_CFLAGS) \ $(COVERAGE_CFLAGS) \ $(WARN_CFLAGS) @@ -29,6 +30,7 @@ LDADDS = \ $(SASL_LIBS) \ $(SELINUX_LIBS) \ $(APPARMOR_LIBS) \ + $(YAJL_LIBS) \ $(WARN_CFLAGS) \ ../src/libvirt_test.la \ ../gnulib/lib/libgnu.la \ @@ -112,6 +114,10 @@ if WITH_CIL check_PROGRAMS += object-locking endif +if HAVE_YAJL +check_PROGRAMS += jsontest +endif + check_PROGRAMS += networkxml2xmltest check_PROGRAMS += networkxml2argvtest @@ -195,6 +201,10 @@ TESTS = virshtest \ virnetsockettest \ $(test_scripts) +if HAVE_YAJL +TESTS += jsontest +endif + if WITH_XEN TESTS += xml2sexprtest \ sexpr2xmltest \ @@ -443,6 +453,10 @@ hashtest_SOURCES = \ hashtest.c hashdata.h testutils.h testutils.c hashtest_LDADD = $(LDADDS) +jsontest_SOURCES = \ + jsontest.c jsondata.h testutils.h testutils.c +jsontest_LDADD = $(LDADDS) + if WITH_LIBVIRTD eventtest_SOURCES = \ eventtest.c testutils.h testutils.c diff --git a/tests/jsontest.c b/tests/jsontest.c new file mode 100644 index 0000000..412f475 --- /dev/null +++ b/tests/jsontest.c @@ -0,0 +1,111 @@ +#include <config.h> + +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <time.h> + +#include "internal.h" +#include "json.h" +#include "testutils.h" + +struct testInfo { + const char *doc; + bool pass; +}; + + +static int +testJSONFromString(const void *data) +{ + const struct testInfo *info = data; + virJSONValuePtr json; + int ret = -1; + + json = virJSONValueFromString(info->doc); + + if (info->pass) { + if (!json) { + if (virTestGetVerbose()) + fprintf(stderr, "Fail to parse %s\n", info->doc); + ret = -1; + goto cleanup; + } else { + if (virTestGetDebug()) + fprintf(stderr, "Parsed %s\n", info->doc); + } + } else { + if (json) { + if (virTestGetVerbose()) + fprintf(stderr, "Should not have parsed %s\n", info->doc); + ret = -1; + goto cleanup; + } else { + if (virTestGetDebug()) + fprintf(stderr, "Fail to parse %s\n", info->doc); + } + } + + ret = 0; + +cleanup: + virJSONValueFree(json); + return ret; +} + + +static int +mymain(void) +{ + int ret = 0; + +#define DO_TEST_FULL(name, cmd, doc, pass) \ + do { \ + struct testInfo info = { doc, pass }; \ + if (virtTestRun(name, 1, testJSON ## cmd, &info) < 0) \ + ret = -1; \ + } while (0) + +#define DO_TEST_PARSE(name, doc) \ + DO_TEST_FULL(name, FromString, doc, true) + + DO_TEST_PARSE("Simple", "{\"return\": {}, \"id\": \"libvirt-1\"}"); + DO_TEST_PARSE("NotSoSimple", "{\"QMP\": {\"version\": {\"qemu\":" + "{\"micro\": 91, \"minor\": 13, \"major\": 0}," + "\"package\": \" (qemu-kvm-devel)\"}, \"capabilities\": []}}"); + + + DO_TEST_PARSE("Harder", "{\"return\": [{\"filename\": " + "\"unix:/home/berrange/.libvirt/qemu/lib/tck.monitor,server\"," + "\"label\": \"charmonitor\"}, {\"filename\": \"pty:/dev/pts/158\"," + "\"label\": \"charserial0\"}], \"id\": \"libvirt-3\"}"); + + DO_TEST_PARSE("VeryHard", "{\"return\": [{\"name\": \"quit\"}, {\"name\":" + "\"eject\"}, {\"name\": \"change\"}, {\"name\": \"screendump\"}," + "{\"name\": \"stop\"}, {\"name\": \"cont\"}, {\"name\": " + "\"system_reset\"}, {\"name\": \"system_powerdown\"}, " + "{\"name\": \"device_add\"}, {\"name\": \"device_del\"}, " + "{\"name\": \"cpu\"}, {\"name\": \"memsave\"}, {\"name\": " + "\"pmemsave\"}, {\"name\": \"migrate\"}, {\"name\": " + "\"migrate_cancel\"}, {\"name\": \"migrate_set_speed\"}," + "{\"name\": \"client_migrate_info\"}, {\"name\": " + "\"migrate_set_downtime\"}, {\"name\": \"netdev_add\"}, " + "{\"name\": \"netdev_del\"}, {\"name\": \"block_resize\"}," + "{\"name\": \"balloon\"}, {\"name\": \"set_link\"}, {\"name\":" + "\"getfd\"}, {\"name\": \"closefd\"}, {\"name\": \"block_passwd\"}," + "{\"name\": \"set_password\"}, {\"name\": \"expire_password\"}," + "{\"name\": \"qmp_capabilities\"}, {\"name\": " + "\"human-monitor-command\"}, {\"name\": \"query-version\"}," + "{\"name\": \"query-commands\"}, {\"name\": \"query-chardev\"}," + "{\"name\": \"query-block\"}, {\"name\": \"query-blockstats\"}, " + "{\"name\": \"query-cpus\"}, {\"name\": \"query-pci\"}, {\"name\":" + "\"query-kvm\"}, {\"name\": \"query-status\"}, {\"name\": " + "\"query-mice\"}, {\"name\": \"query-vnc\"}, {\"name\": " + "\"query-spice\"}, {\"name\": \"query-name\"}, {\"name\": " + "\"query-uuid\"}, {\"name\": \"query-migrate\"}, {\"name\": " + "\"query-balloon\"}], \"id\": \"libvirt-2\"}"); + + return (ret == 0) ?
