[libvirt] driver level connection close event
by Nikolay Shirokovskiy 25 Jun '15

25 Jun '15

Notify of connection close event from parallels driver (possibly) wrapped in the remote driver. Discussion. In 1 and 2 patch we forced to some decisions because we don't have a weak reference mechanics. 1 patch. ----------- virConnectCloseCallback is introduced because we can not reference the connection object itself when setting a network layer callback because of how connection close works. A connection close procedure is next: 1. client closes connection 2. a this point nobody else referencing a connection and it is disposed 3. connection dispose unreferencing network connection 4. network connection disposes Thus if we referece a connection in network close callback we never get step 2. virConnectCloseCallback broke this cycle but at cost that clients MUST unregister explicitly before closing connection. This is not good as this unregistration is not really neaded. Client is not telling that it does not want to receive events anymore but rather forced to obey some implementation-driven rules. 2 patch. ----------- We impose requirements on driver implementations which is fragile. Moreover we again need to make explicit unregistrations. Implementation of domain events illustrates this point. remoteDispatchConnectDomainEventRegister does not reference NetClient and makes unregistration before NetClient is disposed but drivers do not meet the formulated requirements. Object event system release lock before delivering event for re-entrance purposes. Shortly we have 2 undesired consequences here. 1. Mandatory unregistration. 2. Imposing multi-threading requirements. Introduction of weak pointers could free us from these artifacts. Next weak reference workflow illustrates this. 1. Take weak reference on object of interest before passing to party. This doesn't break disposing mechanics as weak eference does not prevent from disposing object. Object is disposed but memory is not freed yet if there are weak references. 2. When callback is called we are safe to check if pointer dangling as we make a weak reference before. 3. Release weak reference and this trigger memory freeing if there are no more weak references. daemon/libvirtd.h | 1 + daemon/remote.c | 87 ++++++++++++++++++++++++++++++++ src/datatypes.c | 112 +++++++++++++++++++++++++++++++---------- src/datatypes.h | 21 ++++++-- src/driver-hypervisor.h | 12 +++++ src/libvirt-host.c | 79 ++++++++++-------------------- src/remote/remote_driver.c | 108 +++++++++++++++++++++++++++++++--------- src/remote/remote_protocol.x | 24 +++++++++- src/remote_protocol-structs | 6 ++ src/vz/vz_driver.c | 26 ++++++++++ src/vz/vz_sdk.c | 32 +++++++++++- src/vz/vz_utils.h | 3 + 12 files changed, 396 insertions(+), 115 deletions(-)

[libvirt] [PATCH] qemu: fix wrong remove guest cfg if migrate fail
by Luyao Huang 25 Jun '15

If we get fail in qemuMigrationPrepareAny, we forget check if the vm is persistent then always call qemuDomainRemoveInactive to clean the inactive settings. Add a check to avoid this.

[libvirt] [PATCH] virt-xml-validate: Allow input to be read from stdin
by Johannes Holmberg 25 Jun '15

--- Hello, I often find myself wanting to validate a domain xml without having to save it to a file, so I've updated virt-xml-validate to support the standard practice of reading from stdin when "-" is given as the input file. Of course, the validation is multipass so there still needs to be a temporary file but I think it makes sense to hide this complexity in virt-xml-validate and not force it onto the user. /Johannes tools/virt-xml-validate.in | 53 +++++++++++++++++++++++++++++++++------------- 1 file changed, 38 insertions(+), 15 deletions(-) diff --git a/tools/virt-xml-validate.in b/tools/virt-xml-validate.in index a04fa06..8807f8d 100644 --- a/tools/virt-xml-validate.in +++ b/tools/virt-xml-validate.in @@ -17,6 +17,16 @@ set -e +TMPFILE= + +cleanup() { + if [ $TMPFILE ]; then + rm -f $TMPFILE + fi +} + +trap cleanup EXIT + case $1 in -h | --h | --he | --hel | --help) cat <<EOF @@ -35,7 +45,7 @@ $0 (libvirt) @VERSION@ EOF exit ;; --) shift ;; - -*) + -?*) echo "$0: unrecognized option '$1'" >&2 exit 1 ;; esac @@ -43,18 +53,27 @@ esac XMLFILE="$1" TYPE="$2" -if [ -z "$XMLFILE" ]; then - echo "syntax: $0 XMLFILE [TYPE]" >&2 - exit 1 -fi - -if [ ! -f "$XMLFILE" ]; then - echo "$0: document $XMLFILE does not exist" >&2 - exit 2 +if [ "$XMLFILE" = "-" ]; then + TMPFILE=`mktemp --tmpdir virt-xml.XXXX` + cat > $TMPFILE +else + if [ -z "$XMLFILE" ]; then + echo "syntax: $0 XMLFILE [TYPE]" >&2 + exit 1 + fi + + if [ ! -f "$XMLFILE" ]; then + echo "$0: document $XMLFILE does not exist" >&2 + exit 2 + fi fi if [ -z "$TYPE" ]; then - ROOT=`xmllint --stream --debug "$XMLFILE" 2>/dev/null | grep "^0 1 " | awk '{ print $3 }'` + if [ $TMPFILE ]; then + ROOT=`cat "$TMPFILE" | xmllint --stream --debug - 2>/dev/null | grep "^0 1 " | awk '{ print $3 }'` + else + ROOT=`xmllint --stream --debug "$XMLFILE" 2>/dev/null | grep "^0 1 " | awk '{ print $3 }'` + fi case "$ROOT" in *domainsnapshot*) # Must come first, since *domain* is a substring TYPE="domainsnapshot" @@ -99,8 +118,11 @@ if [ ! -f "$SCHEMA" ]; then exit 4 fi -xmllint --noout --relaxng "$SCHEMA" "$XMLFILE" - +if [ $TMPFILE ]; then + cat "$TMPFILE" | xmllint --noout --relaxng "$SCHEMA" - +else + xmllint --noout --relaxng "$SCHEMA" "$XMLFILE" +fi exit : <<=cut @@ -119,9 +141,10 @@ exit Validates a libvirt XML for compliance with the published schema.

[libvirt] [PATCH] test: Refactor vcpu pinning and vcpu info retrieval

Drop internal data structures and use the proper fields in virDomainDef. This allows to greatly simplify the code and allows to remove the private data structure that was holding just redundant data.

Changes from v1 Remove "cleanup" label and "goto" operator from prlsdkAttachNet() and prlsdkDetachNet() Replace it with "return" operator. Rename netMac variable to expectedMac in prlsdkGetNetIndex() Move prlsdkGetNetIndex() call after PrlVm_BeginEdit call in prlsdkDetachNet() function.

[libvirt] [sandbox PATCH 00/10] Patches for libvirt-sandbox
by Eren Yagdiran 24 Jun '15

24 Jun '15

Hello, These patches provide disk support for libvirt-sandbox. Implemented '--disk' parameter will be useful when integrating Docker image support for libvirt-sandbox. --Main diffs compared to previous patches. Since many hypervisors, including kvm, will not even honour requested names for disk devices we link each device under /dev/disk/by-tag e.g /dev/disk/by-tag/foobar -> /dev/sda We populate disks.cfg with tag to device mapping when we build the sandbox. After that, in each init-process {Common,Qemu}, we basically read the configuration and populate the right symlinks under /dev/disk/by-tag The common functions for modifying directories are moved under Init-util. {Common,Qemu} inits are using them. Cédric Bosdonnat (2): Add gvir_sandbox_config_has_disks function qemu: use devtmpfs rather than tmpfs to auto-populate /dev Eren Yagdiran (8): Add an utility function for guessing filetype from file extension Add configuration object for disk support Add disk parameter to virt-sandbox Add disk support to the container builder Add disk support to machine builder Init-util : Common directory functions for init-common and init-qemu Common-init: Building symlink from disks.cfg Common-builder: /dev/disk/by-tag/thetag to /dev/vdN bin/virt-sandbox.c | 37 +++ libvirt-sandbox/Makefile.am | 7 +- .../libvirt-sandbox-builder-container.c | 36 ++- libvirt-sandbox/libvirt-sandbox-builder-machine.c | 44 ++- libvirt-sandbox/libvirt-sandbox-builder.c | 73 ++++- libvirt-sandbox/libvirt-sandbox-config-disk.c | 274 +++++++++++++++++++ libvirt-sandbox/libvirt-sandbox-config-disk.h | 82 ++++++ libvirt-sandbox/libvirt-sandbox-config.c | 300 +++++++++++++++++++++ libvirt-sandbox/libvirt-sandbox-config.h | 11 + libvirt-sandbox/libvirt-sandbox-init-common.c | 51 +++- libvirt-sandbox/libvirt-sandbox-init-qemu.c | 151 ++--------- libvirt-sandbox/libvirt-sandbox-init-util.c | 58 ++++ libvirt-sandbox/libvirt-sandbox-init-util.h | 41 +++ libvirt-sandbox/libvirt-sandbox-util.c | 72 +++++ libvirt-sandbox/libvirt-sandbox-util.h | 5 + libvirt-sandbox/libvirt-sandbox.h | 1 + libvirt-sandbox/libvirt-sandbox.sym | 5 + libvirt-sandbox/tests/test-config.c | 11 + po/POTFILES.in | 1 + 19 files changed, 1111 insertions(+), 149 deletions(-) create mode 100644 libvirt-sandbox/libvirt-sandbox-config-disk.c create mode 100644 libvirt-sandbox/libvirt-sandbox-config-disk.h create mode 100644 libvirt-sandbox/libvirt-sandbox-init-util.c create mode 100644 libvirt-sandbox/libvirt-sandbox-init-util.h create mode 100644 libvirt-sandbox/libvirt-sandbox-util.c -- 2.1.0
