[libvirt] virsh vol-upload purpose question
by Li, Chun Wen 21 Aug '12

21 Aug '12

I use virsh vol-upload to upload some data in a volume and use vol-download to download these data from the same volume, both these two commands work well. However, when I first use these two commands, I thought I can use vol-upload to upload some file, then attach this volume to a vm, and access the upload file in this vm. I did this experiment, bud it not success. Once I upload a file into a volume, attach it to a vm, then the vm can not recognize the file type of this vm, if I mkfs to the volume, the file I upload disappear. So, my question is the purpose of the vol-upload is just to save some data in the volume outside vm? I think it is more reasonable if we can access upload data from vm. Best Regards Kimi Li

[libvirt] [ANNOUNCE] libvirt-glib 0.1.2 release
by Daniel P. Berrange 20 Aug '12

20 Aug '12

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.2, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Add async binding for virDomainResume - Fix deadlock in event loop handle/timer removal libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list redhat com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH] ESX:Refactor ESX storage driver and add iSCSI support
by Ata E Husain Bohra 20 Aug '12

20 Aug '12

The patch refactors the current ESX storage driver due to following reasons: 1. Given most of the public APIs exposed by the storage driver in Libvirt remains same, ESX storage driver should not implement logic specific for only one supported format (current implementation only supports VMFS). 2. Decoupling interface from specific storage implementation gives us an extensible design to hook implementation for other supported storage formats. This patch refactors the current driver to implement it as a facade pattern i.e. the driver exposes all the public libvirt APIs, but uses backend drivers to get the required task done. The backend drivers provide implementation specific to the type of storage device. File changes: ------------------ esx_storage_driver.c ----> esx_storage_driver.c (base storage driver) | |---> esx_storage_backend_vmfs.c (VMFS backend) | |---> esx_storage_backend_iscsi.c (iSCSI backend) The patch adds the backend driver to support iSCSI format storage pools and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt is as follows: 1. ESX static iSCSI target <------> Libvirt Storage Pools 2. ESX iSCSI LUNs <------> Libvirt Storage Volumes. The above understanding is based on http://libvirt.org/storage.html. The operation supported on iSCSI pools includes: 1. List storage pools & volumes. 2. Get xml descriptor operaion on pools & volumes. 3. Lookup operation on pools & volumes by name, uuid and path (if applicable). iSCSI pools does not support operations such as: Create / remove pools and volumes --- src/Makefile.am | 2 + src/esx/esx_driver.c | 4 +- src/esx/esx_storage_backend_iscsi.c | 794 +++++++++++++++++++ src/esx/esx_storage_backend_iscsi.h | 31 + src/esx/esx_storage_backend_vmfs.c | 1471 +++++++++++++++++++++++++++++++++++ src/esx/esx_storage_backend_vmfs.h | 31 + src/esx/esx_storage_driver.c | 1303 +++++-------------------------- src/esx/esx_vi.c | 341 +++++++- src/esx/esx_vi.h | 21 +- src/esx/esx_vi_generator.input | 306 ++++++++ src/esx/esx_vi_generator.py | 20 + 11 files changed, 3212 insertions(+), 1112 deletions(-) create mode 100644 src/esx/esx_storage_backend_iscsi.c create mode 100644 src/esx/esx_storage_backend_iscsi.h create mode 100644 src/esx/esx_storage_backend_vmfs.c create mode 100644 src/esx/esx_storage_backend_vmfs.h diff --git a/src/Makefile.am b/src/Makefile.am index 49bcf50..050d6f9 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -476,6 +476,8 @@ ESX_DRIVER_SOURCES = \ esx/esx_interface_driver.c esx/esx_interface_driver.h \ esx/esx_network_driver.c esx/esx_network_driver.h \ esx/esx_storage_driver.c esx/esx_storage_driver.h \ + esx/esx_storage_backend_vmfs.c esx/esx_storage_backend_vmfs.h \ + esx/esx_storage_backend_iscsi.c esx/esx_storage_backend_iscsi.h \ esx/esx_device_monitor.c esx/esx_device_monitor.h \ esx/esx_secret_driver.c esx/esx_secret_driver.h \ esx/esx_nwfilter_driver.c esx/esx_nwfilter_driver.h \ diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 47957cc..4cd9353 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -162,7 +162,7 @@ esxParseVMXFileName(const char *fileName, void *opaque) datastoreName = NULL; if (esxVI_LookupDatastoreHostMount(data->ctx, datastore->obj, - &hostMount) < 0 || + &hostMount, esxVI_Occurrence_RequiredItem) < 0 || esxVI_GetStringValue(datastore, "summary.name", &datastoreName, esxVI_Occurrence_RequiredItem) < 0) { goto cleanup; @@ -306,7 +306,7 @@ esxFormatVMXFileName(const char *fileName, void *opaque) if (esxVI_LookupDatastoreByName(data->ctx, datastoreName, NULL, &datastore, esxVI_Occurrence_RequiredItem) < 0 || esxVI_LookupDatastoreHostMount(data->ctx, datastore->obj, - &hostMount) < 0) { + &hostMount, esxVI_Occurrence_RequiredItem) < 0) { goto cleanup; } diff --git a/src/esx/esx_storage_backend_iscsi.c b/src/esx/esx_storage_backend_iscsi.c new file mode 100644 index 0000000..4f79a0f --- /dev/null +++ b/src/esx/esx_storage_backend_iscsi.c @@ -0,0 +1,794 @@ +/* + * esx_storage_backend_iscsi.c: ESX storage backend for iSCSI handling + * + * Copyright (C) 2007-2008, 2010-2012 Red Hat, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[libvirt] [PATCHv2] selinux: Fix incorrect object label generation.
by Viktor Mihajlovski 20 Aug '12

20 Aug '12

This is a fix for the object label generation. It uses a new flag for virSecuritySELinuxGenNewContext that specifies whether the context is for an object. If so the context role remains unchanged. Without this fix it is not possible to start domains with image file or block device backed storage when selinux is enabled.

[libvirt] [PATCHv5 0/2] Rework of Disk Geometry Support
by Viktor Mihajlovski 20 Aug '12

20 Aug '12

With qemu it is possible to override the geometry (cylinders, heads, sectors) of disks. This series adds a new XML tag for geometry and the related support in the qemu driver. V2 Changes: Refactor into the generic domain configuration/XML support for disk geometry and a qemu specific part with the testcase V3 Changes: 1. Use virReportError instead of custom xxxReportError. 2. Moved the geometry element to diskspec, so it applies to all kind of disks. V4 Changes: Rebase for libvirt 0.10.0 freeze.
