[libvirt] [PATCH 00/13] libxl: add basic support for migration
by Jim Fehlig
Based on an earlier patch from Chunyan Liu
https://www.redhat.com/archives/libvir-list/2013-September/msg00667.html
This patch series adds basic migration support to the libxl driver.
Follow-up patches can improve pre-migration checks and add support for
additional migration flags.
Patches 1-12 are almost exclusively code motion, moving functions from
the main driver module into the libxl_domain and libxl_conf modules.
Patch13 is rather large and provides the migration implementation. If it
is preferred to split patch13 further, I'm open to suggestions on ways to
do that.
I've done some basic migration testing of this series using NFS shared
storage. Error handling only minimally tested though. I attempted a
migration to host with a different bridge than the source, verifying
the migration failed and the vm was resumed on the source.
Jim Fehlig (13):
libxl: move libxlDomainEventQueue to libxl_domain
libxl: move libxlDomainManagedSavePath to libxl_domain
libxl: move libxlSaveImageOpen to libxl_domain
libxl: move libxlVmCleanup{,Job} to libxl_domain
libxl: move libxlDomEventsRegister to libxl_domain
libxl: move libxlDomainAutoCoreDump to libxl_domain
libxl: move libxlDoNodeGetInfo to libxl_conf
libxl: move libxlDomainSetVcpuAffinities to libxl_domain
libxl: move libxlFreeMem to libxl_domain
libxl: move libxlVmStart to libxl_domain
libxl: include a pointer to the driver in libxlDomainObjPrivate
libxl: move domain event handler to libxl_domain
libxl: add migration support

[libvirt] [PATCH] qemu: monitor: Provide more information in generic block job error
by Peter Krempa
The qemuMonitorJSONBlockJob handles a few errors internally. If qemu
returns a different error we would report a rather unhelpful message:
$ virsh blockpull gluster-job vda --base /dev/null
error: internal error: Unexpected error
As the actual message from qemu contains a bit more info, let's use it
to report something a little more useful:
$ virsh blockpull gluster-job vda --base /dev/null
error: internal error: Unexpected error: (GenericError) 'Base '/dev/null' not found'

[libvirt] [PATCHv8 0/2] Implement RBD storage pool support
by Adam Walters
This is an updated version of my RBD storage pool support patch. Relevant
changes since v7 are:
- Fixed bug where I compared disk->srcpool->mode to VIR_DOMAIN_DISK_TYPE_NETWORK
In response to a couple of items Ján mentioned, I decided not to pursue adding
anything to qemuxml2argvtest. The reason I decided not to pursue this is there is
not really any need. In comparison with other volume types, RBD already has the
same test coverage. Namely, a base set of test-cases without using storage pools,
plus a generic storage pool test.
In addition, I also attempted to implement a proper check for expected vs actual
secret usage, but at that particular point in the code, Ján was correct that the
pool definition has not yet been parsed. Thus, I had to keep my bypass.

[libvirt] [PATCH v13 00/49] write separate module for hostdev passthrough
by Chunyan Liu
These patches implements a separate module for hostdev passthrough so that it
could be shared by different drivers and can maintain a global state of a host
device.
Patches 1~6 are to switch existing qemu and lxc driver to use common library
lists, so that to maintain a global state of every host device.
Patches 7~45 are to extract general code from qemu_hostdev.c piece by piece,
make them reusable common APIs.
Patches 46: unit test for the virhostdev common library
Patches 47: add a hostdev backend type for xen
Patches 48: add pci passthrough to libxl driver based on the common library
Patches 49: change lxc to use common library APIs

[libvirt] [PATCH v4 0/3] support dumping guest memory in compressed format
by qiaonuohan
dumping guest's memroy is introduced without compression supported, and this is
a freature regression of 'virsh dump --memory-only'. This patchset is used to
add support in libvirt side to make qemu dump guest's memory in kdump-compressed
format and please refer the following address to see implementation of the qemu
side, the lastest version of qemu side is v9(ready for being queued).
http://lists.nongnu.org/archive/html/qemu-devel/2014-02/msg03016.html
ChangLog:
Changes from v3 to v4:
1. dropping patch "add dump_memory_format in qemu.conf"
2. fix to follow some conventions
Changes from v2 to v3:
1. address Jiri Denemark's comment about adding a new public API instead of
changing an old one.
Changes from v1 to v2:
1. address Daniel P. Berrange's comment about using a new parameter to replace
flags like VIR_DUMP_COMPRESS_ZLIB.
qiaonuohan (3):
add new virDomainCoreDumpWithFormat API
add qemu support to virDomainCoreDumpWithFormat API
allow "virsh dump --memory-only" specify dump format

[libvirt] [Question] Will we support to set boot order online?
by Wangyufei (James)
Hello,
I find that QEMU supports to set boot(QMP command "boot_set") order online, namely the virtual machine
can be reboot in appointed order, but libvirt had no corresponding interface. So, I want to know if libvirt intend to
support to set boot order online. If the answer is yes, I'll try to apply the patch. If no, why?
Best Regards,
-WangYufei

[libvirt] [PATCH 0/4] Expose FSFreeze/FSThaw within the guest as commands
by Tomoki Sekiyama
Currently FSFreeze and FSThaw are supported by qemu guest agent and they are
used internally in snapshot-create command with --quiesce option.
However, when users want to utilize the native snapshot feature of storage
devices (such as LVM over iSCSI, various enterprise storage systems, etc.),
they need to issue fsfreeze command separately from libvirt-driven snapshots.
(OpenStack cinder provides these storages' snapshot feature, but it cannot
quiesce the guest filesystems automatically for now.)
Although virDomainQemuGuestAgent() API could be used for this purpose, it
depends too much on specific hypervisor implementation.
This patchset adds virDomainFSFreeze()/virDomainFSThaw() APIs and virsh
domfsfreeze/domfsthaw commands to enable the users to freeze and thaw
domain's filesystems cleanly.
The APIs has mountPoint and flags option currently unsupported for future
extension, as virDomainFSTrim() API.
Duplicated FSFreeze results in error caused by qemu guest agent.

Tomoki Sekiyama (4):
Introduce virDomainFSFreeze() public API
remote: Implement virDomainFSFreeze and virDomainFSThaw
qemu: Implement virDomainFSFreeze
virsh: Expose new virDomainFSFreeze and virDomainFSThaw API
