[libvirt] [PATCH] iohelper: Don't report errors on special FDs
by Michal Privoznik 06 Nov '12

06 Nov '12

Some FDs may not implement fdatasync() functionality, e.g. pipes or stdout. In that case EINVAL or EROFS is returned. We don't want to fail then nor report any error.

[libvirt] [PATCH] iohelper: Don't try to fdatasync(stdout)
by Christophe Fergeau 05 Nov '12

05 Nov '12

After upgrading to libvirt 1.0.0, I've started getting warnings from libvirt: (gnome-boxes:5965): Libvirt.GObject-CRITICAL **: cannot finish stream: internal error libvirt_iohelper: unable to fsync stdout: Invalid argument On further investigation, in iohelper.c:runIO(), fdatasync can get called on STDOUT_FILENO, which indeed returns EINVAL when this happens.

[libvirt] [PATCHv4 00/51] another round of snapshot patches
by Eric Blake 05 Nov '12

05 Nov '12

I think I've addressed most findings from round 3 - by implementing the ability to redefine a snapshot, it becomes possible to restore snapshot hierarchy when recreating a transient domain by the same name. New goodies in this round: several bug fixes, add virsh snapshot-edit, drop undefine --snapshots-full (you can only remove snapshot metadata on undefine). I tested as I went, but this went through so many rebases that there may be some nasties that snuck in; but I wanted to get this posted now. I also know that I'm missing at least one major feature requested in the v3 review: namely, transient domains _should_ auto-remove snapshot metadata files when they halt, but right now aren't doing that. v3 was at: https://www.redhat.com/archives/libvir-list/2011-August/msg01132.html Also available here: git fetch git://repo.or.cz/libvirt/ericb.git snapshot or browse online at: http://repo.or.cz/w/libvirt/ericb.git/shortlog/refs/heads/snapshot I'm also trying to group things by several bugzilla related to various patches (looks like I still need to create a few): Eric Blake (51): https://bugzilla.redhat.com/show_bug.cgi?id=674537 snapshot: fix corner case on OOM during creation https://bugzilla.redhat.com/show_bug.cgi?id=733762 snapshot: better events when starting paused snapshot: fine-tune ability to start paused snapshot: expose --running and --paused in virsh snapshot: fine-tune qemu saved images starting paused snapshot: improve reverting to qemu paused snapshots snapshot: properly revert qemu to offline snapshots snapshot: fine-tune qemu snapshot revert states no bug filed yet... should be one about no stale metadata snapshot: allow deletion of just snapshot metadata snapshot: add snapshot-list --parent to virsh https://bugzilla.redhat.com/show_bug.cgi?id=733529 snapshot: speed up snapshot location snapshot: avoid crash when deleting qemu snapshots snapshot: track current domain across deletion of children snapshot: simplify acting on just children no bug filed yet... should be one about no stale metadata snapshot: let qemu discard only snapshot metadata snapshot: identify which snapshots have metadata snapshot: reflect new dumpxml and list options in virsh snapshot: identify qemu snapshot roots snapshot: allow recreation of metadata snapshot: refactor virsh snapshot creation snapshot: improve virsh snapshot-create, add snapshot-edit snapshot: add qemu snapshot creation without metadata no bug filed yet... should be one about snapshot migration snapshot: add qemu snapshot redefine support snapshot: prevent stranding snapshot data on domain destruction snapshot: teach virsh about new undefine flags snapshot: refactor some qemu code snapshot: cache qemu-img location snapshot: support new undefine flags in qemu snapshot: prevent migration from stranding snapshot data https://bugzilla.redhat.com/show_bug.cgi?id=638510 snapshot: refactor domain xml output snapshot: allow full domain xml in snapshot snapshot: correctly escape generated xml snapshot: update rng to support full domain in xml snapshot: store qemu domain details in xml snapshot: additions to domain xml for disks snapshot: reject transient disks where code is not ready snapshot: introduce new deletion flag snapshot: expose new delete flag in virsh snapshot: allow halting after snapshot snapshot: expose halt-after-creation in virsh snapshot: wire up new qemu monitor command snapshot: support extra state in snapshots snapshot: add <disks> to snapshot xml snapshot: also support disks by path snapshot: add virsh domblklist command snapshot: add flag for requesting disk snapshot snapshot: wire up disk-only flag to snapshot-create snapshot: reject unimplemented disk snapshot features snapshot: make it possible to audit external snapshot snapshot: wire up live qemu disk snapshots snapshot: use SELinux and lock manager with external snapshots docs/formatdomain.html.in | 40 +- docs/formatsnapshot.html.in | 269 ++- docs/schemas/Makefile.am | 1 + docs/schemas/domain.rng | 2555 +------------------- docs/schemas/{domain.rng => domaincommon.rng} | 32 +- docs/schemas/domainsnapshot.rng | 84 +- examples/domain-events/events-c/event-test.c | 37 +- include/libvirt/libvirt.h.in | 66 +- src/conf/domain_audit.c | 12 +- src/conf/domain_audit.h | 4 +- src/conf/domain_conf.c | 902 ++++++-- src/conf/domain_conf.h | 76 +- src/esx/esx_driver.c | 38 +- src/libvirt.c | 256 ++- src/libvirt_private.syms | 8 + src/libxl/libxl_conf.c | 5 + src/libxl/libxl_driver.c | 11 +- src/qemu/qemu_command.c | 5 + src/qemu/qemu_conf.h | 1 + src/qemu/qemu_driver.c | 1532 +++++++++--- src/qemu/qemu_hotplug.c | 18 +- src/qemu/qemu_migration.c | 48 +- src/qemu/qemu_migration.h | 2 -

[libvirt] for initial review: updated doc for DHCPv6
by Gene Czarcinski 04 Nov '12

04 Nov '12

I have taken a shot at updating the libvirt documentation for DHCPv6 support and am attaching the resulting patch. This is a sanity check and not a submission. I will submit the documentation patch when I submit the patches which actually do the work. Is there any other documentation I should be updating? Gene
