[libvirt] [PATCH] qemu: Rework handling of shutdown event
by Jiri Denemark 05 Dec '11

05 Dec '11

When QEMU guest finishes its shutdown sequence, qemu stops virtual CPUs and when started with -no-shutdown waits for us to kill it using SGITERM. Since QEMU is flushing its internal buffers, some time may pass before QEMU actually dies. We mistakenly used "paused" state (and events) for this which is quite confusing since users may see a domain going to pause while they expect it to shutdown. Since we already have "shutdown" state with "the domain is being shut down" semantics, we should use it for this state. However, the state didn't have a corresponding event so I created one and called its detail as VIR_DOMAIN_EVENT_SHUTDOWN_FINISHED (guest OS finished its shutdown sequence) with the intent to add VIR_DOMAIN_EVENT_SHUTDOWN_STARTED in the future if we have a sufficiently capable guest agent that can notify us when guest OS starts to shutdown. --- include/libvirt/libvirt.h.in | 10 +++ src/qemu/qemu_process.c | 126 ++++++++++++++++++++++++++++++------------ 2 files changed, 100 insertions(+), 36 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index d01d1bc..8d4a049 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -2288,6 +2288,7 @@ typedef enum { VIR_DOMAIN_EVENT_SUSPENDED = 3, VIR_DOMAIN_EVENT_RESUMED = 4, VIR_DOMAIN_EVENT_STOPPED = 5, + VIR_DOMAIN_EVENT_SHUTDOWN = 6, } virDomainEventType;

[libvirt] [PATCH] Introduce gvir_set_error (and friends) & convert all code

This mirrors g_set_error, but uses gvir_xml_error_new. The main benefit of using gvxr_xml_set_error over gvir_xml_error_new is that it handles NULL GError **. --- libvirt-gconfig/libvirt-gconfig-helpers-private.h | 2 + libvirt-gconfig/libvirt-gconfig-helpers.c | 40 ++++++++++++++++----- libvirt-gconfig/libvirt-gconfig-object.c | 32 ++++++---------- 3 files changed, 45 insertions(+), 29 deletions(-) diff --git a/libvirt-gconfig/libvirt-gconfig-helpers-private.h b/libvirt-gconfig/libvirt-gconfig-helpers-private.h index 0a35595..b5b4878 100644 --- a/libvirt-gconfig/libvirt-gconfig-helpers-private.h +++ b/libvirt-gconfig/libvirt-gconfig-helpers-private.h @@ -32,6 +32,8 @@ G_BEGIN_DECLS GError *gvir_xml_error_new(GQuark domain, gint code, const gchar *format, ...); +void gvir_xml_set_error(GError **error, GQuark domain, gint code, + const gchar *format, ...); xmlNodePtr gvir_config_xml_parse(const char *xml, const char *root_node, GError **err); diff --git a/libvirt-gconfig/libvirt-gconfig-helpers.c b/libvirt-gconfig/libvirt-gconfig-helpers.c index 722fe3d..bfdcfc3 100644 --- a/libvirt-gconfig/libvirt-gconfig-helpers.c +++ b/libvirt-gconfig/libvirt-gconfig-helpers.c @@ -59,6 +59,22 @@ static GError *gvir_xml_error_new_literal(GQuark domain, } +static GError *gvir_xml_error_new_va(GQuark domain, + gint code, + const gchar *format, + va_list args) +{ + GError *err; + gchar *message; + + message = g_strdup_vprintf(format, args); + err = gvir_xml_error_new_literal(domain, code, message); + + g_free(message); + + return err; +} + GError *gvir_xml_error_new(GQuark domain, gint code, const gchar *format, @@ -66,17 +82,25 @@ GError *gvir_xml_error_new(GQuark domain, { GError *err; va_list args; - gchar *message; va_start(args, format); - message = g_strdup_vprintf(format, args); + err = gvir_xml_error_new_va(domain, code, format, args); va_end(args); - err = gvir_xml_error_new_literal(domain, code, message); + return err; +} - g_free(message); +void gvir_xml_set_error(GError **error, GQuark domain, gint code, + const gchar *format, ...) +{ + va_list args; - return err; + if (error == NULL) + return; + + va_start(args, format); + *error = gvir_xml_error_new_va(domain, code, format, args); + va_end(args); } xmlNodePtr @@ -94,10 +118,8 @@ gvir_config_xml_parse(const char *xml, const char *root_node, GError **err) doc = xmlParseMemory(xml, strlen(xml)); if (!doc) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "%s", - "Unable to parse configuration"); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, + 0, "%s", "Unable to parse configuration"); return NULL; } if ((!doc->children) || (strcmp((char *)doc->children->name, root_node) != 0)) { diff --git a/libvirt-gconfig/libvirt-gconfig-object.c b/libvirt-gconfig/libvirt-gconfig-object.c index 03c7d5a..e2597f5 100644 --- a/libvirt-gconfig/libvirt-gconfig-object.c +++ b/libvirt-gconfig/libvirt-gconfig-object.c @@ -202,28 +202,23 @@ void gvir_config_object_validate(GVirConfigObject *config, xmlSetStructuredErrorFunc(NULL, gvir_xml_structured_error_nop); if (!priv->node) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "%s", - "No XML document associated with this config object"); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, 0, "%s", + "No XML document associated with this config object"); return; } rngParser = xmlRelaxNGNewParserCtxt(priv->schema); if (!rngParser) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "Unable to create RNG parser for %s", - priv->schema); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, 0, + "Unable to create RNG parser for %s", + priv->schema); return; } rng = xmlRelaxNGParse(rngParser); if (!rng) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "Unable to parse RNG %s", - priv->schema); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, 0, + "Unable to parse RNG %s", priv->schema); xmlRelaxNGFreeParserCtxt(rngParser); return; } @@ -231,19 +226,16 @@ void gvir_config_object_validate(GVirConfigObject *config, rngValid = xmlRelaxNGNewValidCtxt(rng); if (!rngValid) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "Unable to create RNG validation context %s", - priv->schema); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, 0, + "Unable to create RNG validation context %s", + priv->schema); xmlRelaxNGFree(rng); return; } if (xmlRelaxNGValidateDoc(rngValid, priv->node->doc) != 0) { - *err = gvir_xml_error_new(GVIR_CONFIG_OBJECT_ERROR, - 0, - "%s", - "Unable to validate doc"); + gvir_xml_set_error(err, GVIR_CONFIG_OBJECT_ERROR, 0, + "%s", "Unable to validate doc"); xmlRelaxNGFreeValidCtxt(rngValid); xmlRelaxNGFree(rng); return; -- 1.7.7.3

[libvirt] [PATCH 0/2] Expose virNodeGetCPUStats and virNodeGetMemoryStats in python
by Peter Krempa 05 Dec '11

05 Dec '11

These patches add two API functions to the libvirt python bindings, that were missing. The constants denoting a summary stat value instead of a separate per-node values was declared using a preprocessor macro: ... #define VIR_NODE_MEMORY_STATS_ALL_CELLS (-1) #define VIR_NODE_CPU_STATS_ALL_CPUS (-1) ... This inhibits automatic generation of these constants in the automaticaly generated python library code. If this change is too controversial, there's another option: Including these constants in the python library (using libvirt-override.py). Please let me know which of those options you prefer. Thanks Peter Peter Krempa (2): python: Expose binding for virNodeGetCPUStats() python: Expose binding for virNodeGetMemoryStats() include/libvirt/libvirt.h.in | 12 +++-- - change macro definitions to enums python/libvirt-override-api.xml | 14 ++++++ - add doc's about newly added functions python/libvirt-override.c | 95 +++++++++++++++++++++++++++++++++++++++ - add code for calling those functions and reclaiming return values. 3 files changed, 117 insertions(+), 4 deletions(-) -- 1.7.3.4
