[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.

Didn't have time to fix this today; virVirtualPortProfileFormat is conditionally implemented based on PROXY, but unconditionally called.

[libvirt] [PATCH v2] esx: Add read-only storage pool access
by Matthias Bolte 26 May '10

26 May '10

Allows listing existing pools and requesting information about them. Alter the esxVI_ProductVersion enum in a way that allows to check for product type by masking. Changes in v2: - split not directly related parts into separate patches - simplify goto usage: don't jump backwards - rework format of esxVI_ProductVersion values and explain the format - expand a FIXME in esxStoragePoolGetXMLDesc --- po/POTFILES.in | 1 + src/esx/esx_storage_driver.c | 597 +++++++++++++++++++++++++++++++++++++++- src/esx/esx_vi.c | 126 ++++++++- src/esx/esx_vi.h | 33 ++- src/esx/esx_vi_generator.input | 59 ++++ src/esx/esx_vi_generator.py | 7 +- 6 files changed, 794 insertions(+), 29 deletions(-) diff --git a/po/POTFILES.in b/po/POTFILES.in index 88218bd..e047b1b 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -19,6 +19,7 @@ src/cpu/cpu_map.c src/cpu/cpu_x86.c src/datatypes.c src/esx/esx_driver.c +src/esx/esx_storage_driver.c src/esx/esx_util.c src/esx/esx_vi.c src/esx/esx_vi_methods.c diff --git a/src/esx/esx_storage_driver.c b/src/esx/esx_storage_driver.c index 97b92a5..0e2e1a3 100644 --- a/src/esx/esx_storage_driver.c +++ b/src/esx/esx_storage_driver.c @@ -29,6 +29,7 @@ #include "memory.h" #include "logging.h" #include "uuid.h" +#include "storage_conf.h" #include "esx_private.h" #include "esx_storage_driver.h" #include "esx_vi.h" @@ -65,17 +66,587 @@ esxStorageClose(virConnectPtr conn) +static int +esxNumberOfStoragePools(virConnectPtr conn) +{ + int count = 0; + esxPrivate *priv = conn->storagePrivateData; + esxVI_ObjectContent *datastoreList = NULL; + esxVI_ObjectContent *datastore = NULL; + + if (esxVI_EnsureSession(priv->host) < 0) { + return -1; + } + + if (esxVI_LookupObjectContentByType(priv->host, priv->host->datacenter, + "Datastore", NULL, esxVI_Boolean_True, + &datastoreList) < 0) { + return -1; + } + + for (datastore = datastoreList; datastore != NULL; + datastore = datastore->_next) { + ++count; + } + + esxVI_ObjectContent_Free(&datastoreList); + + return count; +} + + + +static int +esxListStoragePools(virConnectPtr conn, char **const names, int maxnames) +{ + bool success = false; + esxPrivate *priv = conn->storagePrivateData; + esxVI_String *propertyNameList = NULL; + esxVI_DynamicProperty *dynamicProperty = NULL; + esxVI_ObjectContent *datastoreList = NULL; + esxVI_ObjectContent *datastore = NULL; + int count = 0; + int i; + + if (names == NULL || maxnames < 0) { + ESX_ERROR(VIR_ERR_INVALID_ARG, "%s", _("Invalid argument")); + return -1; + } + + if (maxnames == 0) { + return 0; + } + + if (esxVI_EnsureSession(priv->host) < 0) { + return -1; + } + + if (esxVI_String_AppendValueToList(&propertyNameList, + "summary.name") < 0 || + esxVI_LookupObjectContentByType(priv->host, priv->host->datacenter, + "Datastore", propertyNameList, + esxVI_Boolean_True, + &datastoreList) < 0) { + goto cleanup; + } + + for (datastore = datastoreList; datastore != NULL; + datastore = datastore->_next) { + for (dynamicProperty = datastore->propSet; dynamicProperty != NULL; + dynamicProperty = dynamicProperty->_next) { + if (STREQ(dynamicProperty->name, "summary.name")) { + if (esxVI_AnyType_ExpectType(dynamicProperty->val, + esxVI_Type_String) < 0) { + goto cleanup; + } + + names[count] = strdup(dynamicProperty->val->string); + + if (names[count] == NULL) { + virReportOOMError(); + goto cleanup; + } + + ++count; + break; + } else { + VIR_WARN("Unexpected '%s' property", dynamicProperty->name); + } + } + } + + success = true; + + cleanup: + if (! success) { + for (i = 0; i < count; ++i) { + VIR_FREE(names[i]); + } + + count = -1; + } + + esxVI_String_Free(&propertyNameList); + esxVI_ObjectContent_Free(&datastoreList); + + return count; +} + + + +static int +esxNumberOfDefinedStoragePools(virConnectPtr conn ATTRIBUTE_UNUSED) +{ + /* ESX storage pools are always active */ + return 0; +} + + + +static int +esxListDefinedStoragePools(virConnectPtr conn ATTRIBUTE_UNUSED, + char **const names ATTRIBUTE_UNUSED, + int maxnames ATTRIBUTE_UNUSED) +{ + /* ESX storage pools are always active */ + return 0; +} + + + +static virStoragePoolPtr +esxStoragePoolLookupByName(virConnectPtr conn, const char *name) +{ + esxPrivate *priv = conn->storagePrivateData; + esxVI_String *propertyNameList = NULL; + esxVI_ObjectContent *datastore = NULL; + esxVI_Boolean accessible = esxVI_Boolean_Undefined; + char *summaryUrl = NULL; + char *suffix = NULL; + int suffixLength; + char uuid_string[VIR_UUID_STRING_BUFLEN] = "00000000-00000000-0000-000000000000"; + unsigned char uuid[VIR_UUID_BUFLEN]; + char *realName = NULL; + virStoragePoolPtr pool = NULL; + + if (esxVI_EnsureSession(priv->host) < 0) { + return NULL; + } + + if (esxVI_String_AppendValueListToList(&propertyNameList, + "summary.accessible\0" + "summary.name\0" + "summary.url\0") < 0 || + esxVI_LookupDatastoreByName(priv->host, name, + propertyNameList, &datastore, + esxVI_Occurrence_RequiredItem) < 0 || + esxVI_GetBoolean(datastore, "summary.accessible", + &accessible, esxVI_Occurrence_RequiredItem) < 0) { + goto cleanup; + } + + /* + * Datastores don't have a UUID.

[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;

[libvirt] avoid new "make check" failure and fix a related bug
by Jim Meyering 26 May '10

26 May '10

In reviewing/testing some incoming patches, I noticed a new "make check" failure. There were two problems: - not diagnosing an invalid host UUID. The lack of this diagnostic made it slightly more challenging to track down the next problem: - not accommodating the fact that our template now contains an invalid line; before the addition of "host_uuid", each commented-out sample line was valid. Here are the fixes. >From 11228f4b2dba1b43a9de97a575d1121eba2e8cf4 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 25 May 2010 20:56:18 +0200 Subject: [PATCH 1/2] libvirtd: diagnose invalid host UUID * daemon/libvirtd.c (remoteReadConfigFile): Diagnose an invalid host UUID rather than silently exiting with status 7. --- daemon/libvirtd.c | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index 8fa78b8..e86f78d 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -2843,8 +2843,10 @@ remoteReadConfigFile (struct qemud_server *server, const char *filename) GET_CONF_INT (conf, filename, max_client_requests); GET_CONF_STR (conf, filename, host_uuid); - if (virSetHostUUIDStr(host_uuid)) + if (virSetHostUUIDStr(host_uuid)) { + VIR_ERROR(_("invalid host UUID: %s"), host_uuid); goto free_and_fail; + } VIR_FREE(host_uuid); -- 1.7.1.342.g1c280 >From 6d20ae23fe5a5e64a0cf1be1f0b9cebce49625c1 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 25 May 2010 21:08:37 +0200 Subject: [PATCH 2/2] tests: avoid new failure of the daemon-conf test * tests/daemon-conf: Accommodate the fact that out template, daemon/libvirtd.conf now contains an invalid host_uuid.

[libvirt] [PATCH v7] [REPOST] add 802.1Qbh and 802.1Qbg handling
by Stefan Berger 25 May '10

25 May '10

Reposting due to malformatted patch. This patch builds on the work recently posted by Stefan Berger. It builds on top of Stefan's three posted patches: [PATCH v10] vepa: parsing for 802.1Qb{g|h} XML [RFC][PATCH 1/3] vepa+vsi: Introduce dependency on libnl [PATCH v3] Add host UUID (to libvirt capabilities) Stefan's RFC patches 2/3 and 3/3 are incorporated into my patch. V7: - Addressing Jim Meyering's comments; this also touches existing code for example for correcting indentation of break statements or simplification of switch statements. Changes from v5 to v6: - Renamed occurrencvirVirtualPortProfileDef to virVirtualPortProfileParamses - 802.1Qbg part prepared for sending a RTM_SETLINK and getting processing status back plus a subsequent RTM_GETLINK to get IFLA_PORT_RESPONSE. Note: This interface for 802.1Qbg may still change Changes from v4 to v5: - [David Allan] move getPhysfn inside IFLA_VF_PORT_MAX to avoid compiler warning when latest if_link.h isn't available Changes from v3 to v4: - move from Stefan's 802.1Qb{g|h} XML v8 to v9 - move hostuuid and vf index calcs to inside doPortProfileOp8021Qbh Changes from v2 to v3: - remove debug fprintfs - use virGetHostUUID (thanks Stefan!) - fix compile issue when latest if_link.h isn't available - change poll timeout to 10s, at 1/8 intervals - if polling times out, log msg and return -ETIMEDOUT Changes from v1 to v2: - Add Stefan's code for getPortProfileStatus - Poll for up to 2 secs for port-profile status, at 1/8 sec intervals: - if status indicates error, abort openMacvtapTap - if status indicates success, exit polling - if status is "in-progress" after 2 secs of polling, exit polling loop silently, without error My patch finishes out the 802.1Qbh parts, which Stefan had mostly complete. I've tested using the recent kernel updates for VF_PORT netlink msgs and enic for Cisco's 10G Ethernet NIC. I tested many VMs, each with several direct interfaces, each configured with a port-profile per the XML. VM-to-VM, and VM-to-external work as expected. VM-to-VM on same host (using same NIC) works same as VM-to-VM where VMs are on diff hosts. I'm able to change settings on the port-profile while the VM is running to change the virtual port behaviour. For example, adjusting a QoS setting like rate limit. All VMs with interfaces using that port-profile immediatly see the effect of the change to the port-profile. I don't have a SR-IOV device to test so source dev is a non-SR-IOV device, but most of the code paths include support for specifing the source dev and VF index. We'll need to complete this by discovering the PF given the VF linkdev. Once we have the PF, we'll also have the VF index. All this info- mation is available from sysfs.

[libvirt] [PATCH] qemu: Allow using regular audio backends with VNC
by Cole Robinson 25 May '10

25 May '10

Currently all host audio backends are disabled if a VM is using VNC, in favor of the QEMU VNC audio extension. Unfortunately no released VNC client supports this extension, so users have no way of getting audio to work if using VNC. Add a new config option in qemu.conf which allows changing libvirt's behavior, but keep the default intact.
