[libvirt] [libvirt-glib] [PATCH v2] GVirDomainSnapshot: Add gvir_domain_snapshot_delete

by Timm Bäder

--- Whoops, totally forgot about the delete flags in the first version, sorry. As for the underline in domain_snapshot, I took that from gvir_domain_snapshot_get_config so I don't really know what's the correct version. Since this is using gvir_domain_snapshot_get_name now, the patch removing the #if 0's in libvirt-gobject-domain-snapshot.c is needed. libvirt-gobject/libvirt-gobject-domain-snapshot.c | 25 +++++++++++++++++++++++ libvirt-gobject/libvirt-gobject-domain-snapshot.h | 16 +++++++++++++++ libvirt-gobject/libvirt-gobject.sym | 6 ++++++ 3 files changed, 47 insertions(+) diff --git a/libvirt-gobject/libvirt-gobject-domain-snapshot.c b/libvirt-gobject/libvirt-gobject-domain-snapshot.c index fcf70ed..aa0504d 100644 --- a/libvirt-gobject/libvirt-gobject-domain-snapshot.c +++ b/libvirt-gobject/libvirt-gobject-domain-snapshot.c @@ -205,3 +205,28 @@ GVirConfigDomainSnapshot *gvir_domain_snapshot_get_config free(xml); return conf; } + +/** + * gvir_domain_snapshot_delete: + * @snapshot: the domain snapshot + * @flags: Bitwise or of #GVirDomainSnapshotDeleteFlags + * @error: (allow-none): Place-holder for error or NULL + */ +void gvir_domain_snapshot_delete (GVirDomainSnapshot *snapshot, + GVirDomainSnapshotDeleteFlags flags, + GError **error) +{ + GVirDomainSnapshotPrivate *priv; + int status; + + g_return_if_fail(GVIR_IS_DOMAIN_SNAPSHOT (snapshot)); + g_return_if_fail(error == NULL || *error == NULL); + + priv = snapshot->priv; + status = virDomainSnapshotDelete(priv->handle, flags); + if (status < 0) { + gvir_set_error(error, GVIR_DOMAIN_SNAPSHOT_ERROR, 0, + "Unable to delete snapshot `%s'", + gvir_domain_snapshot_get_name(snapshot)); + } +} diff --git a/libvirt-gobject/libvirt-gobject-domain-snapshot.h b/libvirt-gobject/libvirt-gobject-domain-snapshot.h index 5bd827c..3985795 100644 --- a/libvirt-gobject/libvirt-gobject-domain-snapshot.h +++ b/libvirt-gobject/libvirt-gobject-domain-snapshot.h @@ -58,6 +58,18 @@ struct _GVirDomainSnapshotClass gpointer padding[20]; }; +/** + * GVirDomainSnapshotDeleteFlags: + * @GVIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN: Also delete children + * @GVIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY: Delete just metadata + * @GVIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY: Delete just children + */ +typedef enum { + GVIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN = 1, + GVIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY = 2, + GVIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY = 4 +} GVirDomainSnapshotDeleteFlags; + GType gvir_domain_snapshot_get_type(void); GType gvir_domain_snapshot_handle_get_type(void); @@ -69,6 +81,10 @@ GVirConfigDomainSnapshot *gvir_domain_snapshot_get_config guint flags, GError **err); +void gvir_domain_snapshot_delete (GVirDomainSnapshot *snapshot, + guint flags, + GError **error); + G_END_DECLS #endif /* __LIBVIRT_GOBJECT_DOMAIN_SNAPSHOT_H__ */ diff --git a/libvirt-gobject/libvirt-gobject.sym b/libvirt-gobject/libvirt-gobject.sym index f2419ac..232e63b 100644 --- a/libvirt-gobject/libvirt-gobject.sym +++ b/libvirt-gobject/libvirt-gobject.sym @@ -234,4 +234,10 @@ LIBVIRT_GOBJECT_0.1.5 { gvir_connection_open_read_only_finish; } LIBVIRT_GOBJECT_0.1.4; +LIBVIRT_GOBJECT_0.1.9 { + global: + gvir_domain_snapshot_delete_flags_get_type; + gvir_domain_snapshot_delete; +} LIBVIRT_GOBJECT_0.1.5; + # .... define new API here using predicted next version number .... -- 1.9.3

[libvirt] [PATCH v5] Add helper program to create custom leases

by Nehal J Wani

Introduce helper program to catch events from dnsmasq and maintain a custom lease file per network. It supports dhcpv4 and dhcpv6. The file is saved as "<interface-name>.status". Each lease contains the following info: <expiry-time (epoch time)> <mac> <iaid> <ip-address> <hostname> <clientid> Example of custom leases file content: [ { "iaid": "1221229", "ip-address": "2001:db8:ca2:2:1::95", "mac-address": "52:54:00:12:a2:6d", "hostname": "Fedora20", "client-id": "00:04:1a:c1:d9:6b:5a:0a:e2:bc:f8:4b:1e:37:2e:38:22:55", "expiry-time": 1393244216 }, { "ip-address": "192.168.150.208", "mac-address": "52:54:00:11:56:b3", "hostname": "Wani-PC", "client-id": "01:52:54:00:11:56:b3", "expiry-time": 1393244248 } ] src/Makefile.am: * Add options to compile the helper program src/network/bridge_driver.c: * Introduce networkDnsmasqLeaseFileNameCustom() * Invoke helper program along with dnsmasq * Delete the .status file when corresponding n/w is destroyed. src/network/leaseshelper.c * Helper program to create the custom lease file --- v5: * More comments added, for better explanation * Use of virFileFindResource() to identify proper path to helper binary * Use of VIR_ENUM_IMPL for handling action events added v4: * Addition of pidfile and a corresponding lock for it * Make correction for dnsmasq < 2.52 (Only IPv4) * Move helper file from src/util to src/network * Increase limit on max size of leases file * Refer: https://www.redhat.com/archives/libvir-list/2014-March/msg01038.html v3: * Improved file handling, removed redundant copying, introduced --help and --version * Refer: https://www.redhat.com/archives/libvir-list/2014-February/msg01431.html v2: * Changed format to JSON * Refer: https://www.redhat.com/archives/libvir-list/2014-January/msg01234.html v1: * Refer: https://www.redhat.com/archives/libvir-list/2014-January/msg00626.html src/Makefile.am | 22 +++ src/network/bridge_driver.c | 27 ++++ src/network/leaseshelper.c | 360 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 409 insertions(+), 0 deletions(-) create mode 100644 src/network/leaseshelper.c diff --git a/src/Makefile.am b/src/Makefile.am index dd0abe7..fbe72c4 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -859,6 +859,9 @@ STORAGE_HELPER_DISK_SOURCES = \ UTIL_IO_HELPER_SOURCES = \ util/iohelper.c +NETWORK_LEASES_HELPER_SOURCES = \ + network/leaseshelper.c + # Network filters NWFILTER_DRIVER_SOURCES = \ nwfilter/nwfilter_driver.h nwfilter/nwfilter_driver.c \ @@ -2466,6 +2469,25 @@ libvirt_iohelper_CFLAGS = \ $(AM_CFLAGS) \ $(PIE_CFLAGS) \ $(NULL) + +if WITH_NETWORK +libexec_PROGRAMS += libvirt_leaseshelper +libvirt_leaseshelper_SOURCES = $(NETWORK_LEASES_HELPER_SOURCES) +libvirt_leaseshelper_LDADD = \ + libvirt_util.la \ + ../gnulib/lib/libgnu.la +if WITH_DTRACE_PROBES +libvirt_leaseshelper_LDADD += libvirt_probes.lo +endif WITH_DTRACE_PROBES + +libvirt_leaseshelper_CFLAGS = \ + $(AM_CFLAGS) \ + $(PIE_CFLAGS) \ + $(NULL) +else !

[libvirt] [PATCH] virsh: Check wether found volume is member of the specified storage pool

When looking up storage volumes virsh uses multiple lookup steps. Some of the steps don't require a pool name specified.

[libvirt] Release fo libvirt-1.2.5

by Daniel Veillard

As planned the release of libvirt 1.2.5 is out, it is tagged in git and available as tarballs and rpms at the usual place: ftp://libvirt.org/libvirt/ This is a relatively small release in the number of commits, around 150, but includes a security fix (which happened to be my fault !) and 2 new set of APIs. There is also some interesting refactoring work and the usual flow of bug fixes, so people are really invited to update: Security: - LSN-2014-0003: Don't expand entities when parsing XML (Daniel P. Berrange) Features: - Introduce virDomain{Get,Set}Time APIs (Michal Privoznik) - Introduce virDomainFSFreeze() and virDomainFSThaw() public API (Tomoki Sekiyama) Portability: - build: avoid compiler warning on 32-bit platform (Eric Blake) -

[libvirt] [PATCH] util: fix DST end date in virtimetest timezones

by Laine Stump

Reported by: Roman Bogorodskiy <bogorodskiy(a)gmail.com> Some of the tests for virTimeLocalOffsetFromUTC set an imaginary timezone that attempts to force dyalight savings time active all the time by setting a start date of 0/00:00:00 and end date of 366/23:59:59. Since the day is 0-based, 366 really means "day 367" which will never occur - this was an attempt to eliminate problems with DST not being active in some cases right around midnight on January 1. Even though it didn't completely solve the problem, it didn't seem to cause harm so it was left in the test timezones. Although Linux glibc doesn't mind having a DST end date of 366, FreeBSD refuses to use such timezones, so the tests fail. This patch changes the 366 to 365. This may or may not cause failure of the remaining DST tests around midnight Jan 1. If so, we will need to disable those tests at year's end too. --- Pushed as a build breaker. tests/virtimetest.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/tests/virtimetest.c b/tests/virtimetest.c index 749a112..859bd13 100644 --- a/tests/virtimetest.c +++ b/tests/virtimetest.c @@ -192,13 +192,13 @@ mymain(void) * have DST in effect; what's more, cover a zone with * with an unusual DST different than a usual one hour */ - TEST_LOCALOFFSET("VIR-00:30VID,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR-00:30VID,0/00:00:00,365/23:59:59", ((1 * 60) + 30) * 60); - TEST_LOCALOFFSET("VIR-02:30VID,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR-02:30VID,0/00:00:00,365/23:59:59", ((3 * 60) + 30) * 60); - TEST_LOCALOFFSET("VIR-02:30VID-04:30,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR-02:30VID-04:30,0/00:00:00,365/23:59:59", ((4 * 60) + 30) * 60); - TEST_LOCALOFFSET("VIR-12:00VID-13:00,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR-12:00VID-13:00,0/00:00:00,365/23:59:59", ((13 * 60) + 0) * 60); if (!isNearYearEnd()) { @@ -214,11 +214,11 @@ mymain(void) * tests, except on Dec 31 and Jan 1. */ - TEST_LOCALOFFSET("VIR02:45VID00:45,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR02:45VID00:45,0/00:00:00,365/23:59:59", -45 * 60); - TEST_LOCALOFFSET("VIR05:00VID04:00,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR05:00VID04:00,0/00:00:00,365/23:59:59", ((-4 * 60) + 0) * 60); - TEST_LOCALOFFSET("VIR11:00VID10:00,0/00:00:00,366/23:59:59", + TEST_LOCALOFFSET("VIR11:00VID10:00,0/00:00:00,365/23:59:59", ((-10 * 60) + 0) * 60); } -- 1.9.3

[libvirt] [PATCHv2 0/4] qemu: fix broken RTC_CHANGE event when clock offset='variable'

by Laine Stump

(the cover letter from V1 has been preserved here with small updates) This patch series is all about: https://bugzilla.redhat.com/show_bug.cgi?id=964177 which points out a flaw in qemu's RTC_CHANGE event when the base for the guest's real time clock was given as an explicit date (rather than as 'utc' or 'localtime'). Patch 3/4 explains what qemu does, and how this patch fixes it (for the case of basis='utc' - an additional fix to properly support basis='localtime', both for RTC_CHANGE and when migrating across timezone/DST boundaries, is in Patch 4/4). (NB: the flawed RTC_CHANGE offset has been in QEMU for so long now that it has been documented and cannot be changed, so libvirt must work around it) In the meantime, the fix for basis='localtime' required that we learn the offset of localtime from utc, and that seems like something we might want to do for other reasons, so Patch 1/4 adds a new utility function do get that value that is (I hope!) POSIX compliant. Since the original patch to fix this problem was incorrect, and the new patch doesn't use any of its code, Patch 2/4 reverts that patch completely. Note that I have tested this patch by starting a domain with several variations of <clock> parameters (in a locale that is currently at UTC+3) and using the following short script to add and remove seconds from the guest's RTC while watching both the <clock> line in /var/run/libvirt/qemu/$domain.xml and the offset value sent in libvirt's VIR_DOMAIN_EVENT_ID_RTC_CHANGE event (using examples/domain-events/events-c/event-test from a libvirt source tree that has been built). All cases appear to maintain the adjustment in the status properly, as well as sending the correct value to any event handler. Here is the script I used to add/remove time from the RTC: #!/bin/sh old=$(hwclock --show | cut -f1-7 -d' ') oldabs=$(date +%s --date="$old") newabs=$(expr $oldabs + $1) new=$(date --date="@$newabs") echo Old: $oldabs $old echo New: $newabs $new hwclock --set --date="@$newabs" Laine Stump (4): util: new function virTimeLocalOffsetFromUTC Revert "qemu: Report the offset from host UTC for RTC_CHANGE event" qemu: fix RTC_CHANGE event for <clock offset='variable' basis='utc'/> qemu: fix <clock offset='variable' basis='localtime'/> src/conf/domain_conf.c | 32 +++++++++++++------------------- src/conf/domain_conf.h | 8 +++++--- src/libvirt_private.syms | 1 + src/qemu/qemu_command.c | 43 ++++++++++++++++++++++++++++++------------- src/qemu/qemu_process.c | 34 +++++++++++++++++++--------------- src/util/virtime.c | 41 ++++++++++++++++++++++++++++++++++++++++- src/util/virtime.h | 5 +++-- tests/virtimetest.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 155 insertions(+), 53 deletions(-) -- 1.9.0
