[libvirt] [PATCH] Fix failing virGetHostname.
by Chris Lalancette 26 May '10

26 May '10

We've been running into a lot of situations where virGetHostname() is returning "localhost", where a plain gethostname() would have returned the correct thing. This is because virGetHostname() is *always* trying to canonicalize the name returned from gethostname(), even when it doesn't have to. This patch changes virGetHostname so that if the value returned from gethostname() is already FQDN or localhost, it returns that string directly. If the value returned from gethostname() is a shortened hostname, then we try to canonicalize it. If that succeeds, we returned the canonicalized hostname. If that fails, and/or returns "localhost", then we just return the original string we got from gethostname() and hope for the best. Note that after this patch it is up to clients to check whether "localhost" is an allowed return value. The only place where it's currently not is in qemu migration.

[libvirt] [PATCH v3] Fix up basic migration.
by Chris Lalancette 26 May '10

26 May '10

Basic live migration was broken by the commit that added non-shared block support in two ways: 1) It added a virCheckFlags() to doNativeMigrate(). Besides the fact that typical usage of virCheckFlags() is in driver entry points, and doNativeMigrate() is not an entry point, it was missing important flags like VIR_MIGRATE_LIVE. Move the virCheckFlags to the top-level qemuDomainMigratePrepare2 and friends. 2) It also added a memory leak in qemuMonitorTextMigrate() by not freeing the memory used by virBufferContentAndReset(). This is fixed by storing the pointer in a temporary variable and freeing it at the end. With this patch in place, normal live migration works again. v3: Instead of the churn for virCheckFlagsUI and UL, instead always promote flags to an unsigned long and always use %lx for the fprintf. v2: Add back flags check, which required adding virCheckFlagsUI and virCheckFlagsUL Signed-off-by: Chris Lalancette <clalance(a)redhat.com> --- src/internal.h | 7 ++++--- src/qemu/qemu_driver.c | 30 +++++++++++++++++++++++++++--- src/qemu/qemu_monitor_text.c | 10 +++++++--- 3 files changed, 38 insertions(+), 9 deletions(-) diff --git a/src/internal.h b/src/internal.h index c3c5311..fab3e11 100644 --- a/src/internal.h +++ b/src/internal.h @@ -212,15 +212,16 @@ */ # define virCheckFlags(supported, retval) \ do { \ - if ((flags & ~(supported))) { \ + unsigned long __unsuppflags = flags & ~(supported); \ + if (__unsuppflags) { \ virReportErrorHelper(NULL, \ VIR_FROM_THIS, \ VIR_ERR_INVALID_ARG, \ __FILE__, \ __FUNCTION__, \ __LINE__, \ - _("%s: unsupported flags (0x%x)"), \ - __FUNCTION__, flags & ~(supported)); \ + _("%s: unsupported flags (0x%lx)"), \ + __FUNCTION__, __unsuppflags); \ return retval; \ } \ } while (0) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 77e71cc..941b482 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -10175,6 +10175,15 @@ qemudDomainMigratePrepare2 (virConnectPtr dconn, int ret = -1; int internalret; + virCheckFlags(VIR_MIGRATE_LIVE | + VIR_MIGRATE_PEER2PEER | + VIR_MIGRATE_TUNNELLED | + VIR_MIGRATE_PERSIST_DEST | + VIR_MIGRATE_UNDEFINE_SOURCE | + VIR_MIGRATE_PAUSED | + VIR_MIGRATE_NON_SHARED_DISK | + VIR_MIGRATE_NON_SHARED_INC, -1); + *uri_out = NULL; qemuDriverLock(driver); @@ -10356,9 +10365,6 @@ static int doNativeMigrate(struct qemud_driver *driver, qemuDomainObjPrivatePtr priv = vm->privateData; unsigned int background_flags = 0; - virCheckFlags(VIR_MIGRATE_NON_SHARED_DISK | VIR_MIGRATE_NON_SHARED_INC, - -1); - /* Issue the migrate command. */ if (STRPREFIX(uri, "tcp:") && !STRPREFIX(uri, "tcp://")) { /* HACK: source host generates bogus URIs, so fix them up */ @@ -10779,6 +10785,15 @@ qemudDomainMigratePerform (virDomainPtr dom, int resume = 0; qemuDomainObjPrivatePtr priv; + virCheckFlags(VIR_MIGRATE_LIVE | + VIR_MIGRATE_PEER2PEER | + VIR_MIGRATE_TUNNELLED | + VIR_MIGRATE_PERSIST_DEST | + VIR_MIGRATE_UNDEFINE_SOURCE | + VIR_MIGRATE_PAUSED | + VIR_MIGRATE_NON_SHARED_DISK | + VIR_MIGRATE_NON_SHARED_INC, -1); + qemuDriverLock(driver); vm = virDomainFindByUUID(&driver->domains, dom->uuid); if (!vm) { @@ -10882,6 +10897,15 @@ qemudDomainMigrateFinish2 (virConnectPtr dconn, virErrorPtr orig_err; int newVM = 1; + virCheckFlags(VIR_MIGRATE_LIVE | + VIR_MIGRATE_PEER2PEER | + VIR_MIGRATE_TUNNELLED | + VIR_MIGRATE_PERSIST_DEST | + VIR_MIGRATE_UNDEFINE_SOURCE | + VIR_MIGRATE_PAUSED | + VIR_MIGRATE_NON_SHARED_DISK | + VIR_MIGRATE_NON_SHARED_INC, NULL); + /* Migration failed.

[libvirt] [PATCH v10] vepa: parsing for 802.1Qb{g|h} XML
by Stefan Berger 26 May '10

26 May '10

Below is David Alan's original patch with lots of changes. In particular, it now parses the following two XML descriptions, one for 802.1Qbg and 802.1Qbh and stored the data internally. The actual triggering of the switch setup protocol has not been implemented here but the relevant code to do that should go into the functions associatePortProfileId() and disassociatePortProfileId(). <interface type='direct'> <source dev='eth0.100' mode='vepa'/> <model type='virtio'/> <virtualport type='802.1Qbg'> <parameters managerid='12' typeid='0x123456' typeidversion='1' instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/> </virtualport> <filterref filter='clean-traffic'/> </interface> <interface type='direct'> <source dev='eth0.100' mode='vepa'/> <model type='virtio'/> <virtualport type='802.1Qbh'> <parameters profileid='my_profile'/> </virtualport> </interface> I'd suggest to use this patch as a base for triggering the setup protocol with the 802.1Qb{g|h} switch. V10: - Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams as per Daniel Berrange's request V9: -Addressing Daniel Berrange's comments: - removing macvtap.h's dependency on domain_conf.h by moving the virVirtualPortProfileDef structure into macvtap.h and not passing virtDomainNetDefPtr to any functions in macvtap.c Changes from V7 to V8: - Addressed most of Chris Wright's comments: - indicating error in case virtualport XML node cannot be parsed properly - parsing hex and decimal numbers using virStrToLong_ui() with parameter '0' for base - tgifname (target interface name) variable wasn't necessary to pass to openMacvtapTap function anymore - assigning the virtual port data structure to the virDomainNetDef only if it was previously parsed -> still leaving possibility to start a domain with macvtap but no profile Changes from V6 to V7: - make sure that the error code returned by openMacvtapTap() is a negative number in case the associatePortProfileId() function failed. Changes from V5 to V6: - renaming vsi in the XML to virtualport - replace all occurrences of vsi in the source as well Changes from V4 to V5: - removing mode and MAC address parameters from the functions that will communicate with the hareware diretctly or indirectly Changes from V3 to V4: - moving the associate and disassociate functions to the end of the file for subsequent patches to easier make them generally available for export - passing the macvtap interface name rather than the link device since this otherwise gives funny side effects when using netlink messages where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev all of a sudden gets the MAC address of the macvtap interface. - Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case we wanted to use hook scripts for the setup and so the setup doesn't fail here. Changes from V2 to V3: - if instance ID UUID is not supplied it will automatically be generated - adapted schema to make instance ID UUID optional - added test case Some of the changes from V1 to V2: - parser and XML generator have been separated into their own functions so they can be re-used elsewhere (passthrough case for example) - Adapted XML parser and generator support the above shown type (802.1Qbg, 802.1Qbh). - Adapted schema to above XML - Adapted test XML to above XML - Passing through the VM's UUID which seems to be necessary for 802.1Qbh -- sorry no host UUID - adding virtual function ID to association function, in case it's necessary to use (for SR-IOV) Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com> >From a945107f047c7cd71f9c1b74fd74c47d8cdc3670 Mon Sep 17 00:00:00 2001 From: David Allan <dallan(a)redhat.com> Date: Fri, 12 Mar 2010 13:25:04 -0500 Subject: [PATCH 1/1] POC of port profile id support * Modified schema per DanPB's feedback * Added test for modified schema --- docs/schemas/domain.rng | 69 +++++++++++ src/conf/domain_conf.c | 202 +++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 2 src/qemu/qemu_conf.c | 21 +-- src/qemu/qemu_conf.h | 5 src/qemu/qemu_driver.c | 19 +-- src/util/macvtap.c | 137 ++++++++++++++++++++-- src/util/macvtap.h | 45 ++++++- tests/domainschemadata/portprofile.xml | 36 +++++ 9 files changed, 498 insertions(+), 38 deletions(-) create mode 100644 tests/domainschemadata/portprofile.xml Index: libvirt-acl/docs/schemas/domain.rng =================================================================== --- libvirt-acl.orig/docs/schemas/domain.rng +++ libvirt-acl/docs/schemas/domain.rng @@ -817,6 +817,9 @@ </optional> <empty/> </element> + <optional> + <ref name="virtualPortProfile"/> + </optional> <ref name="interface-options"/> </interleave> </group> @@ -902,6 +905,45 @@ </optional> </interleave> </define> + <define name="virtualPortProfile"> + <choice> + <group> + <element name="virtualport"> + <attribute name="type"> + <value>802.1Qbg</value> + </attribute> + <element name="parameters"> + <attribute name="managerid"> + <ref name="uint8range"/> + </attribute> + <attribute name="typeid"> + <ref name="uint24range"/> + </attribute> + <attribute name="typeidversion"> + <ref name="uint8range"/> + </attribute> + <optional> + <attribute name="instanceid"> + <ref name="UUID"/> + </attribute> + </optional> + </element> + </element> + </group> + <group> + <element name="virtualport"> + <attribute name="type"> + <value>802.1Qbh</value> + </attribute> + <element name="parameters"> + <attribute name="profileid"> + <ref name="virtualPortProfileID"/> + </attribute> + </element> + </element> + </group> + </choice> + </define>  @@ -1769,4 +1811,31 @@ <param name="pattern">[a-zA-Z0-9_\.:]+</param> </data> </define> + <define name="uint8range"> + <choice> + <data type="string"> + <param name="pattern">0x[0-9a-fA-F]{1,2}</param> + </data> + <data type="int"> + <param name="minInclusive">0</param> + <param name="maxInclusive">255</param> + </data> + </choice> + </define> + <define name="uint24range"> + <choice> + <data type="string"> + <param name="pattern">0x[0-9a-fA-F]{1,6}</param> + </data> + <data type="int"> + <param name="minInclusive">0</param> + <param name="maxInclusive">16777215</param> + </data> + </choice> + </define> + <define name="virtualPortProfileID"> + <data type="string"> + <param name="maxLength">39</param> + </data> + </define> </grammar> Index: libvirt-acl/src/conf/domain_conf.c =================================================================== --- libvirt-acl.orig/src/conf/domain_conf.c +++ libvirt-acl/src/conf/domain_conf.c @@ -242,6 +242,11 @@ VIR_ENUM_IMPL(virDomainNetdevMacvtap, VI "private", "bridge") +VIR_ENUM_IMPL(virVirtualPort, VIR_VIRTUALPORT_TYPE_LAST, + "none", + "802.1Qbg", + "802.1Qbh") + VIR_ENUM_IMPL(virDomainClockOffset, VIR_DOMAIN_CLOCK_OFFSET_LAST, "utc", "localtime", @@ -1807,6 +1812,190 @@ cleanup: } +static int +virVirtualPortProfileParamsParseXML(xmlNodePtr node, + virVirtualPortProfileParamsPtr virtPort) +{ + int ret = -1;
