[libvirt] [PATCH v2] docs: Properly mark acl.html dependencies
by Michal Privoznik 26 Jun '15

26 Jun '15

The acl.html file includes aclperms.htmlinc which is generated. However, acl.html is generated too from acl.html.tmp. And in fact, this is the place where the aclperms file is needed. Fix the dependency in Makefile.

[libvirt] Bug: vnc + websocket = websocket autoport not working right at live migration
by Piotr Rybicki 25 Jun '15

25 Jun '15

Hello. Problem description: When i start qemu via libvirt with vnc websocket defined, it is not possible to live migrate to host where other qemu process is running with the same display id. migration error is: error: internal error: early end of file from monitor: possible problem: [1] => 2015-06-23T11:54:25.590506Z qemu-system-x86_64: -vnc 0.0.0.0:1,websocket=5700,password: Failed to start VNC server on `(null)': Failed to bind socket: Address already in use (please note vnc display id=1 and websocket=5700 - where it should be 5701) in libvirt's xml i have: (...) <graphics type='vnc' port='-1' autoport='yes' websocket='-1' listen='0.0.0.0' passwd='xxx'> <listen type='address' address='0.0.0.0'/> </graphics> (...) for first and only qemu process on host, this creates qemu commandline: (...) -vnc 0.0.0.0:0,websocket=5700,password (...) for second qemu process on the same host: (...) -vnc 0.0.0.0:1,websocket=5701,password (...) There is no problem with migration, when there is no websocket configuration. Solution: I believe, to solve this problem, libvirt has to omit websocket port definition in commandline string ('websocket=5700' => 'websocket') when autoport is defined in domain xml definition. from man qemu: -vnc display[,option[,option[,...]]] (...) websocket Opens an additional TCP listening port dedicated to VNC Websocket connections. By definition the Websocket port is 5700+display. If host is specified connections will only be allowed from this host. As an alternative the Websocket port could be specified by using "websocket"=port. TLS encryption for the Websocket connection is supported if the required certificates are specified with the VNC option x509. So if I understand it right, not specifying websocket port means 5700+display id, and display id is given via commandline and increments just fine. Can anyone confirm this? Or perhaps there is some misconfiguration in my xml domain definition? Best regards Piotr Rybicki

[libvirt] [PATCH] qemu_hotplug: try harder to eject media
by Pavel Hrdina 25 Jun '15

25 Jun '15

Some guests lock the tray and QEMU eject command will simply fail to eject the media. But the guest OS can handle this attempt to eject the media and can unlock the tray and open it. In this case, we should try again to actually eject the media. If the first attempt fails we will wait for tray to open and try again to eject the media, but if the second attempt fails, returns with error.

[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] virt-xml-validate: Allow input to be read from stdin

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
