[libvirt] [PATCH v3 0/5] Support of auto-dump on watchdog event in libvirtd
by Hu Tao 02 Dec '10

02 Dec '10

This patch series adds a new watchdog action `dump' which lets libvirtd can do auto-dump when receiving a watchdog event from qemu guest. In order to make the function work, there must be a watchdog device added to guest, and guest must have a watchdog daemon running, for example, /etc/init.d/watchdog start or auto-started on boot. Changes from v2: - let default auto-dump dir be /var/lib/libvirt/qemu/dump Hu Tao (5): Add a threadpool implementation Fall back to QEMUD_SAVE_FORMAT_RAW if compression method fails. Add a new function doCoreDump Add a watchdog action `dump' Add me to AUTHORS to make `make syntax-check' happy AUTHORS | 1 + src/Makefile.am | 3 +- src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 1 + src/qemu/qemu.conf | 5 + src/qemu/qemu_conf.c | 13 +++- src/qemu/qemu_conf.h | 4 + src/qemu/qemu_driver.c | 235 ++++++++++++++++++++++++++++++++++-------------- src/util/threadpool.c | 140 ++++++++++++++++++++++++++++ src/util/threadpool.h | 35 +++++++ 10 files changed, 367 insertions(+), 71 deletions(-) create mode 100644 src/util/threadpool.c create mode 100644 src/util/threadpool.h -- 1.7.3 -- Thanks, Hu Tao

[libvirt] CGROUPS network classID setting in domain
by D. Herrendoerfer 01 Dec '10

01 Dec '10

Hello, I'm looking into the possibility of putting a network(tc) classID into to the domain description and adding it into a (possibly) mounted cgroup directory upon launch of a VM. Has anyone before looked into this ? I've seen this mentioned in an abstract by Daniel B. I imagine a classid entry to look somewhat like: <domain type='qemu'> <name > foo</name> <uuid>3e3fce45-4f53-4fa7-bb32-11f34168b82b </uuid> ... <classid>0x1234</classid> ... Thoughts ? Best regards, D. Herrendoerfer

[libvirt] [v3] virsh: Categorize commands into groups for virsh help
by Osier Yang 01 Dec '10

01 Dec '10

Change the virsh help out. The new output of "virsh help" and "virsh --help" will be like: Secret (help keyword 'secret'): secret-define define or modify a secret from an XML file secret-dumpxml secret attributes in XML secret-set-value set a secret value secret-get-value Output a secret value secret-undefine undefine a secret secret-list list secrets Snapshot (help keyword 'snapshot'): snapshot-create Create a snapshot snapshot-current Get the current snapshot snapshot-delete Delete a domain snapshot snapshot-dumpxml Dump XML for a domain snapshot snapshot-list List snapshots for a domain snapshot-revert Revert a domain to a snapshot Also support output help information of specified command group, e.g. % ./tools/virsh help "Network Filter" Network Filter (help keyword 'filter'): nwfilter-define define or update a network filter from an XML file nwfilter-undefine undefine a network filter nwfilter-dumpxml network filter information in XML nwfilter-list list network filters nwfilter-edit edit XML configuration for a network filter Each group has a help keyword, e.g. % ./tools/virsh help filter Network Filter (help keyword 'filter'): nwfilter-define define or update a network filter from an XML file nwfilter-undefine undefine a network filter nwfilter-dumpxml network filter information in XML nwfilter-list list network filters nwfilter-edit edit XML configuration for a network filter * tools/virsh.c: - introduce new struct "vshCmdGrp" and macros to define the groups. - split previous array "commands" into small arrays which are orgnized by group - changed some functions, e.g. "vshCmdDefSearch" - Added new functions, e.g. "vshCmdGrpSearch" - commands of each group are in "alphabetical order" now. - command groups are in "alphabetical order" now. - the commands are categorized with reference of http://wiki.libvirt.org/page/VirshHelpV2 (by Justin) - the modifications doesn't affect tests * TODO: - doc --- tools/virsh.c | 414 ++++++++++++++++++++++++++++++++++++++------------------ 1 files changed, 281 insertions(+), 133 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index aec7749..17dd524 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -131,6 +131,22 @@ typedef enum { } vshCmdOptType; /* + * Command group types + */ +#define VSH_CMD_GRP_DOM_MANAGEMENT "Domain Management" +#define VSH_CMD_GRP_DOM_MONITORING "Domain Monitoring" +#define VSH_CMD_GRP_STORAGE_POOL "Storage Pool" +#define VSH_CMD_GRP_STORAGE_VOL "Storage Volume" +#define VSH_CMD_GRP_NETWORK "Networking" +#define VSH_CMD_GRP_NODEDEV "Node Device" +#define VSH_CMD_GRP_IFACE "Interface" +#define VSH_CMD_GRP_NWFILTER "Network Filter" +#define VSH_CMD_GRP_SECRET "Secret" +#define VSH_CMD_GRP_SNAPSHOT "Snapshot" +#define VSH_CMD_GRP_HOST_AND_HV "Host and Hypervisor" +#define VSH_CMD_GRP_VIRSH "Virsh itself" + +/* * Command Option Flags */ #define VSH_OFLAG_NONE 0 /* without flags */ @@ -207,8 +223,13 @@ typedef struct __vshControl { char *historyfile; /* readline history file name */ } __vshControl; +typedef struct vshCmdGrp { + const char *name; + const char *keyword; /* help keyword */ + const vshCmdDef *commands; +} vshCmdGrp; -static const vshCmdDef commands[]; +static const vshCmdGrp cmdGroups[]; static void vshError(vshControl *ctl, const char *format, ...)

[libvirt] [PATCH v2] 802.1Qbg: use pre-associate state at beginning of incoming migration
by Stefan Berger 30 Nov '10

30 Nov '10

-v2: - changing the vmOpStr array and vmOperation enum to use VIR_ENUM_IMPL and VIR_ENUM_DECL. Renaming the enum to virVMOperationType and adapting the name of the enum constants. This patch introduces the usage of the pre-associate state of the IEEE 802.1Qbg standard on incoming VM migration on the target host. It is in response to bugzilla entry 632750. https://bugzilla.redhat.com/show_bug.cgi?id=632750 For being able to differentiate the exact reason as to why a macvtap device is being created, either due to a VM creation or an incoming VM migration, I needed to pass that reason as a parameter from wherever qemudStartVMDaemon is being called in order to determine whether to send an ASSOCIATE (VM creation) or a PRE-ASSOCIATE (incoming VM migration) towards lldpad. I am also fixing a problem with the virsh domainxml-to-native call on the way. Gerhard successfully tested the patch with a recent blade network 802.1Qbg-compliant switch. The patch should not have any side-effects on the 802.1Qbh support in libvirt, but Roopa (cc'ed) may want to verify this.

[libvirt] [PATCH] OpenVZ: take veid from vmdef->name when defining new domains
by Guido Günther 30 Nov '10

30 Nov '10

Hi, We currently use the next free veid although there's one given in the domain xml. This currently breaks defining new domains since vmdef->name and veid don't match leading to the following error later on: error: Failed to define domain from 110.xml error: internal error Could not set UUID Since silently ignoring vmdef->name is not nice respect it instead. We avoid veid collisions in the upper levels already. O.k. to apply? -- Guido

[libvirt] [PATCH] Log client errors in libvirtd at debug priority
by Matthias Bolte 30 Nov '10

30 Nov '10

This reverts commit Log all errors at level INFO to stop polluting syslog 04bd0360f32ec628ecf7943b3fd1468d6eb2dde5. and makes virRaiseErrorFull() log errors at debug priority when called from inside libvirtd. This stops libvirtd from polluting it's own log with client errors at error priority that'll be reported and logged on the client side anyway. --- This is basically a v2 for https://www.redhat.com/archives/libvir-list/2010-November/msg01060.html v2 logs client error at debug priority in libvirtd instead of not logging them at all.
