[libvirt] CPU tuning in containers
by Sukadev Bhattiprolu 11 Jul '12

11 Jul '12

Following section indicates that CPU tuning with <period> and <quota> tags are only supported for QEMU http://libvirt.org/formatdomain.html#elementsCPUTuning I see this commit in libvirt.git: commit d9724a81b3c53a40f45bf76067a976cce73ed278 Author: Daniel P. Berrange <berrange(a)redhat.com> Date: Thu Nov 10 12:16:26 2011 +0000 Add support for CPU quota/period to LXC driver and the code seems to be included in libvirt-0.9.10-21.el6. I have not had a chance to try on latest libvirt yet, but is it just that the CPUTuning section on the above wiki needs an update ?

[libvirt] [PATCH v4 0/7] file descriptor passing using pass-fd
by Corey Bryant 11 Jul '12

11 Jul '12

libvirt's sVirt security driver provides SELinux MAC isolation for Qemu guest processes and their corresponding image files. In other words, sVirt uses SELinux to prevent a QEMU process from opening files that do not belong to it. sVirt provides this support by labeling guests and resources with security labels that are stored in file system extended attributes. Some file systems, such as NFS, do not support the extended attribute security namespace, and therefore cannot support sVirt isolation. A solution to this problem is to provide fd passing support, where libvirt opens files and passes file descriptors to QEMU. This, along with SELinux policy to prevent QEMU from opening files, can provide image file isolation for NFS files stored on the same NFS mount. This patch series adds the pass-fd QMP monitor command, which allows an fd to be passed via SCM_RIGHTS, and returns the received file descriptor. Support is also added to the block layer to allow QEMU to dup the fd when the filename is of the /dev/fd/X format. This is useful if MAC policy prevents QEMU from opening specific types of files. One nice thing about this approach is that no new SELinux policy is required to prevent open of NFS files (files with type nfs_t). The virt_use_nfs boolean type simply needs to be set to false, and open will be prevented (and dup will be allowed). For example: # setsebool virt_use_nfs 0 # getsebool virt_use_nfs virt_use_nfs --> off Corey Bryant (7): qemu-char: Add MSG_CMSG_CLOEXEC flag to recvmsg qapi: Convert getfd and closefd qapi: Add pass-fd QMP command qapi: Re-arrange monitor.c functions block: Prevent /dev/fd/X filename from being detected as floppy block: Convert open calls to qemu_open osdep: Enable qemu_open to dup pre-opened fd block/raw-posix.c | 22 +++++----- block/raw-win32.c | 4 +- block/vdi.c | 5 ++- block/vmdk.c | 21 ++++------ block/vpc.c | 2 +- block/vvfat.c | 21 +++++----- cutils.c | 26 +++++++++--- dump.c | 3 +- hmp-commands.hx | 6 +-- hmp.c | 18 ++++++++ hmp.h | 2 + main-loop.c | 6 +-- migration-fd.c | 2 +- monitor.c | 120 ++++++++++++++++++++++++++++++++--------------------- monitor.h | 2 +- net.c | 6 ++- osdep.c | 91 ++++++++++++++++++++++++++++++++++++++++ qapi-schema.json | 71 +++++++++++++++++++++++++++++++ qemu-char.c | 2 +- qemu-common.h | 2 +- qmp-commands.hx | 56 ++++++++++++++++++++++--- 21 files changed, 378 insertions(+), 110 deletions(-) -- 1.7.10.2

[libvirt] [PATCH] Support creation of sparse LVM volumes
by Daniel P. Berrange 11 Jul '12

11 Jul '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> When calling 'lvcreate' if specifying both the '-L' and '--virtualsize' options, the latter will be treated as the capacity and the former as the allocation. This can be used to support sparse volume creation. In addition, when listing volumes it is neccessary to include the 'size' field in lvs output, so that we can detect sparse volume allocation correctly. --- src/storage/storage_backend_logical.c | 27 ++++++++++++++++++--------- 1 files changed, 18 insertions(+), 9 deletions(-) diff --git a/src/storage/storage_backend_logical.c b/src/storage/storage_backend_logical.c index 9fe769b..c6e09e6 100644 --- a/src/storage/storage_backend_logical.c +++ b/src/storage/storage_backend_logical.c @@ -171,6 +171,11 @@ virStorageBackendLogicalMakeVol(virStoragePoolObjPtr pool, "%s", _("malformed volume extent size value")); goto cleanup; } + if (virStrToLong_ull(groups[8], NULL, 10, &vol->allocation) < 0) { + virStorageReportError(VIR_ERR_INTERNAL_ERROR, + "%s", _("malformed volume allocation value")); + goto cleanup; + } /* Now parse the "devices" field separately */ regex = strdup(regex_unit); @@ -271,12 +276,12 @@ virStorageBackendLogicalFindLVs(virStoragePoolObjPtr pool, virStorageVolDefPtr vol) { /* - * # lvs --separator , --noheadings --units b --unbuffered --nosuffix --options "lv_name,origin,uuid,devices,seg_size,vg_extent_size" VGNAME - * RootLV,,06UgP5-2rhb-w3Bo-3mdR-WeoL-pytO-SAa2ky,/dev/hda2(0),5234491392,33554432 - * SwapLV,,oHviCK-8Ik0-paqS-V20c-nkhY-Bm1e-zgzU0M,/dev/hda2(156),1040187392,33554432 - * Test2,,3pg3he-mQsA-5Sui-h0i6-HNmc-Cz7W-QSndcR,/dev/hda2(219),1073741824,33554432 - * Test3,,UB5hFw-kmlm-LSoX-EI1t-ioVd-h7GL-M0W8Ht,/dev/hda2(251),2181038080,33554432 - * Test3,Test2,UB5hFw-kmlm-LSoX-EI1t-ioVd-h7GL-M0W8Ht,/dev/hda2(187),1040187392,33554432 + * # lvs --separator , --noheadings --units b --unbuffered --nosuffix --options "lv_name,origin,uuid,devices,seg_size,vg_extent_size,size" VGNAME + * RootLV,,06UgP5-2rhb-w3Bo-3mdR-WeoL-pytO-SAa2ky,/dev/hda2(0),5234491392,33554432,5234491392 + * SwapLV,,oHviCK-8Ik0-paqS-V20c-nkhY-Bm1e-zgzU0M,/dev/hda2(156),1040187392,33554432,1040187392 + * Test2,,3pg3he-mQsA-5Sui-h0i6-HNmc-Cz7W-QSndcR,/dev/hda2(219),1073741824,33554432,1073741824 + * Test3,,UB5hFw-kmlm-LSoX-EI1t-ioVd-h7GL-M0W8Ht,/dev/hda2(251),2181038080,33554432,2181038080 + * Test3,Test2,UB5hFw-kmlm-LSoX-EI1t-ioVd-h7GL-M0W8Ht,/dev/hda2(187),1040187392,33554432,1040187392 * * Pull out name, origin, & uuid, device, device extent start #, segment size, extent size. * @@ -290,10 +295,10 @@ virStorageBackendLogicalFindLVs(virStoragePoolObjPtr pool, * striped, so "," is not a suitable separator either (rhbz 727474). */ const char *regexes[] = { - "^\\s*(\\S+)#(\\S*)#(\\S+)#(\\S+)#(\\S+)#([0-9]+)#(\\S+)#([0-9]+)#?\\s*$" + "^\\s*(\\S+)#(\\S*)#(\\S+)#(\\S+)#(\\S+)#([0-9]+)#(\\S+)#([0-9]+)#([0-9]+)#?\\s*$" }; int vars[] = { - 8 + 9 }; int ret = -1; virCommandPtr cmd; @@ -304,7 +309,7 @@ virStorageBackendLogicalFindLVs(virStoragePoolObjPtr pool, "--units", "b", "--unbuffered", "--nosuffix", - "--options", "lv_name,origin,uuid,devices,segtype,stripes,seg_size,vg_extent_size", + "--options", "lv_name,origin,uuid,devices,segtype,stripes,seg_size,vg_extent_size,size", pool->def->source.name, NULL); if (virStorageBackendRunProgRegex(pool, @@ -718,6 +723,10 @@ virStorageBackendLogicalCreateVol(virConnectPtr conn, "--name", vol->name, NULL); virCommandAddArg(cmd, "-L"); + if (vol->capacity != vol->allocation) { + virCommandAddArgFormat(cmd, "%lluK", VIR_DIV_UP(vol->allocation, 1024)); + virCommandAddArg(cmd, "--virtualsize"); + } virCommandAddArgFormat(cmd, "%lluK", VIR_DIV_UP(vol->capacity, 1024)); if (vol->backingStore.path) virCommandAddArgPair(cmd, "-s", vol->backingStore.path); -- 1.7.7.6
