[libvirt] [PATCH] RFC Libvirt + Openvswitch
by Ansis Atteka 06 Feb '12

06 Feb '12

This patch allows libvirt to add interfaces to already existing Open vSwitch bridges. The following syntax in domain XML file must be used: <interface type='bridge'> <mac address='52:54:00:d0:3f:f2'/> <source bridge='ovsbr'/> <virtualport type='openvswitch'> <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/> </virtualport> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> or if libvirt should auto-generate the interfaceid us following syntax: <interface type='bridge'> <mac address='52:54:00:d0:3f:f2'/> <source bridge='ovsbr'/> <virtualport type='openvswitch'> </virtualport> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> To create Open vSwitch bridge us following command: ovs-vsctl add-br ovsbr 1. This patch has been tested only on Ubuntu 11.10 with KVM 2.

[libvirt] [PATCH] qemu: Fix seamless spice migration
by Jiri Denemark 05 Feb '12

05 Feb '12

Calling qemuDomainMigrateGraphicsRelocate notifies spice clients to connect to destination qemu so that they can seamlessly switch streams once migration is done. Unfortunately, current qemu is not able to accept any connections while incoming migration connection is open. Thus, we need to delay opening the migration connection to the point spice client is already connected to the destination qemu. --- src/qemu/qemu_migration.c | 83 +++++++++++++++++++++++++++++--------------- 1 files changed, 55 insertions(+), 28 deletions(-) diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index 8453a47..687e77d 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1381,6 +1381,7 @@ cleanup: enum qemuMigrationDestinationType { MIGRATION_DEST_HOST, + MIGRATION_DEST_CONNECT_HOST, MIGRATION_DEST_UNIX, MIGRATION_DEST_FD, }; @@ -1519,6 +1520,44 @@ cleanup: } static int +qemuMigrationConnect(struct qemud_driver *driver, + virDomainObjPtr vm, + qemuMigrationSpecPtr spec) +{ + virNetSocketPtr sock; + const char *host; + char *port = NULL; + int ret = -1; + + host = spec->dest.host.name; + if (virAsprintf(&port, "%d", spec->dest.host.port) < 0) { + virReportOOMError(); + return -1; + } + + spec->destType = MIGRATION_DEST_FD; + spec->dest.fd.qemu = -1; + + if (virSecurityManagerSetSocketLabel(driver->securityManager, vm->def) < 0) + goto cleanup; + if (virNetSocketNewConnectTCP(host, port, &sock) == 0) { + spec->dest.fd.qemu = virNetSocketDupFD(sock, true); + virNetSocketFree(sock); + } + if (virSecurityManagerClearSocketLabel(driver->securityManager, vm->def) < 0 || + spec->dest.fd.qemu == -1) + goto cleanup; + + ret = 0; + +cleanup: + VIR_FREE(port); + if (ret < 0) + VIR_FORCE_CLOSE(spec->dest.fd.qemu); + return ret; +} + +static int qemuMigrationRun(struct qemud_driver *driver, virDomainObjPtr vm, const char *cookiein, @@ -1583,6 +1622,11 @@ qemuMigrationRun(struct qemud_driver *driver, if (flags & VIR_MIGRATE_NON_SHARED_INC) migrate_flags |= QEMU_MONITOR_MIGRATE_NON_SHARED_INC; + /* connect to the destination qemu if needed */ + if (spec->destType == MIGRATION_DEST_CONNECT_HOST && + qemuMigrationConnect(driver, vm, spec) < 0) + goto cleanup; + switch (spec->destType) { case MIGRATION_DEST_HOST: ret = qemuMonitorMigrateToHost(priv->mon, migrate_flags, @@ -1590,6 +1634,10 @@ qemuMigrationRun(struct qemud_driver *driver, spec->dest.host.port); break; + case MIGRATION_DEST_CONNECT_HOST: + /* handled above and transformed into MIGRATION_DEST_FD */ + break; + case MIGRATION_DEST_UNIX: if (qemuCapsGet(priv->qemuCaps, QEMU_CAPS_MIGRATE_QEMU_UNIX)) { ret = qemuMonitorMigrateToUnix(priv->mon, migrate_flags, @@ -1712,7 +1760,6 @@ static int doNativeMigrate(struct qemud_driver *driver, xmlURIPtr uribits = NULL; int ret = -1; qemuMigrationSpec spec; - char *tmp = NULL; VIR_DEBUG("driver=%p, vm=%p, uri=%s, cookiein=%s, cookieinlen=%d, " "cookieout=%p, cookieoutlen=%p, flags=%lx, resource=%lu", @@ -1720,6 +1767,7 @@ static int doNativeMigrate(struct qemud_driver *driver, cookieout, cookieoutlen, flags, resource); if (STRPREFIX(uri, "tcp:") && !STRPREFIX(uri, "tcp://")) { + char *tmp; /* HACK: source host generates bogus URIs, so fix them up */ if (virAsprintf(&tmp, "tcp://%s", uri + strlen("tcp:")) < 0) { virReportOOMError(); @@ -1736,41 +1784,20 @@ static int doNativeMigrate(struct qemud_driver *driver, return -1; } - spec.fwdType = MIGRATION_FWD_DIRECT; - - if (qemuCapsGet(priv->qemuCaps, QEMU_CAPS_MIGRATE_QEMU_FD)) { - virNetSocketPtr sock; - - spec.destType = MIGRATION_DEST_FD; - spec.dest.fd.qemu = -1; - - if (virAsprintf(&tmp, "%d", uribits->port) < 0) { - virReportOOMError(); - goto cleanup; - } - if (virSecurityManagerSetSocketLabel(driver->securityManager, vm->def) < 0) - goto cleanup; - if (virNetSocketNewConnectTCP(uribits->server, tmp, &sock) == 0) { - spec.dest.fd.qemu = virNetSocketDupFD(sock, true); - virNetSocketFree(sock); - } - if (virSecurityManagerClearSocketLabel(driver->securityManager, vm->def) < 0 || - spec.dest.fd.qemu == -1) - goto cleanup; - } else { + if (qemuCapsGet(priv->qemuCaps, QEMU_CAPS_MIGRATE_QEMU_FD)) + spec.destType = MIGRATION_DEST_CONNECT_HOST; + else spec.destType = MIGRATION_DEST_HOST; - spec.dest.host.name = uribits->server; - spec.dest.host.port = uribits->port; - } + spec.dest.host.name = uribits->server; + spec.dest.host.port = uribits->port; + spec.fwdType = MIGRATION_FWD_DIRECT; ret = qemuMigrationRun(driver, vm, cookiein, cookieinlen, cookieout, cookieoutlen, flags, resource, &spec, dconn); -cleanup: if (spec.destType == MIGRATION_DEST_FD) VIR_FORCE_CLOSE(spec.dest.fd.qemu); - VIR_FREE(tmp); xmlFreeURI(uribits); return ret; -- 1.7.8.4

[libvirt] [PATCH] maint: consolidate several .gitignore files
by Eric Blake 03 Feb '12

03 Feb '12

Unlike .cvsignore under CVS, git allows for ignoring nested names. We weren't very consistent where new tests were being ignored (some in .gitignore, some in tests/.gitignore), and I found it easier to just consolidate everything. * .gitignore: Subsume entries from subdirectories. * daemon/.gitignore: Delete. * docs/.gitignore: Likewise. * docs/devhelp/.gitignore: Likewise. * docs/html/.gitignore: Likewise. * examples/dominfo/.gitignore: Likewise. *
