[libvirt] [PATCH] qemu: add a check for nodeset in qemuDomainSetNumaParamsLive
by Luyao Huang 25 Aug '15

25 Aug '15

We will try to set the node to cpuset.mems without check if it is available, since we already have helper to check this. Call virNumaNodesetIsAvailable to check if node is available, then try to change it in the cgroup.

[libvirt] [PATCH] fix vol-create when target allocation=0
by Chunyan Liu 25 Aug '15

25 Aug '15

Regression is introduced by commit e30297b0. After that, it will report "Cannot fill file" error with following xml file: <volume> <name>virtinst-vmlinuz-xen.tP1NHh</name> <capacity>4343792</capacity> <allocation>0</allocation> <target> <format type="raw"/> <nocow/> </target> </volume> Because of this, installing xen pv guest with virt-manager fails. Reason is: posix_fallocate(int fd, off_t offset, off_t len) will return EINVAL when len is equal to 0. So, this patch adds a check before calling safezero().

[libvirt] [PATCH] storage: only run safezero if allocation is > 0
by Guido Günther 24 Aug '15

24 Aug '15

While a zero allocation in safezero should be fine it isn't when we use posix_fallocate which returns EINVAL on a zero allocation. While we could skip the zero allocation in safezero_posix_fallocate it's an optimization to do it for all allocations. This fixes vm installation via virtinst for me which otherwise aborts like: Starting install... Retrieving file linux... | 5.9 MB 00:01 ... Retrieving file initrd.gz... | 29 MB 00:07 ... ERROR Couldn't create storage volume 'virtinst-linux.sBgds4': 'cannot fill file '/var/lib/libvirt/boot/virtinst-linux.sBgds4': Invalid argument' --- No idea while this didn't show up earlier though. src/storage/storage_backend.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/storage/storage_backend.c b/src/storage/storage_backend.c index db49739..0418473 100644 --- a/src/storage/storage_backend.c +++ b/src/storage/storage_backend.c @@ -455,7 +455,7 @@ createRawFile(int fd, virStorageVolDefPtr vol, pos = inputvol->target.capacity - remain; } - if (need_alloc) { + if (need_alloc && (vol->target.allocation - pos > 0)) { if (safezero(fd, pos, vol->target.allocation - pos) < 0) { ret = -errno; virReportSystemError(errno, _("cannot fill file '%s'"), -- 2.1.4

[libvirt] compressed stream support
by Vasiliy Tolstov 24 Aug '15

24 Aug '15

I want to able to get VolumeUpload and VolumeUpload compressed on the fly (for example to minimize network load) Some times ago i ask this question in this list, and get some suggestions from developers. But as i see, May be not good to detect compressor from libvirt config, but create new stream functions that have in flags somewhere compressor type. So when data uploaded/downloaded stream Recv/Send functions able to compress/decompress on the fly. But i'm not understand some things: 1) user run volumedownload with offset (uncompressed size) and length. But when user recieve data - resulted len < requested len. How to deal with this? 2) how to display progress when downloading/uploading data? in case of uncompressed size thing very simple (i know all size and transfered), but in case of compressed data how to determine progress ? Thanks! -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru
