[libvirt] Debian packaging for the Java bindings
by Wido den Hollander
Currently the Java bindings for libvirt do not provide a Debian package.
Users with Debian based systems like Ubuntu are now forced to compile from source since
no binary distribution of the JAR file is available.
This patch adds building Debian packages with ant
$ ant deb
This will build a .deb file in the target directory.
It requires dpkg-dev to be installed.

[libvirt] [PATCH v10 0/9] Add basic driver for Parallels Cloud Server
by Dmitry Guryanov
Parallels Cloud Server is a virtualization solution
that allows users to simultaneously run multiple virtual
machines and containers on the same physical server.
More information can be found here: http://www.parallels.com/products/pcs/
Also beta version of Parallels Cloud Server can be downloaded there.
Changes in v10:
* Change the FSF address
* Replace format strings without % with ' "%s", string '
Dmitry Guryanov (9):
parallels: add driver skeleton
add function virCommandNewVAList
parallels: add functions to list domains and get info
parallels: implement functions for domain life cycle management
parallels: get info about serial ports
parallels: add support of VNC remote display
parallels: implement virDomainDefineXML operation for existing
domains
parallels: add storage driver
parallels: implement VM creation

[libvirt] [PATCH v2] qemu: Allow to attach/detach controller device persistently
by Osier Yang
* src/conf/domain_conf.c:
- Add virDomainControllerFind to find controller device by type
and index.
- Add virDomainControllerRemove to remove the controller device
from maintained controler list.
* src/conf/domain_conf.h:
- Declare the two new helpers.
* src/libvirt_private.syms:
- Expose private symbols for the two new helpers.
* src/qemu/qemu_driver.c:
- Support attach/detach controller device persistently
* src/qemu/qemu_hotplug.c:
- Use the two helpers to simplify the codes.

[libvirt] [PATCH] build: don't export avahi syms when unused
by Eric Blake
Detected when building --without-avahi.
* src/libvirt_private.syms (virnetservermdns.h): Move...
* src/libvirt_avahi.syms: ...to new file.
* src/Makefile.am (USED_SYM_FILES, EXTRA_DIST): Use it.
---
I'm debating whether to push this under the build-breaker rule.
Unfortunately, while this solved my build on an Ubuntu machine,
I have other machines which are failing for other symbols (some
SASL related, and one for xenLinuxDomainBlockStats), so it's
probably better to fix everything instead of just half the problem.

[libvirt] [PATCH v4 00/12] Support hypervisor-threads-pin in vcpupin.
by tangchen
Users can use vcpupin command to bind a vcpu thread to a specific physical cpu.
But besides vcpu threads, there are alse some other threads created by qemu
(known as hypervisor threads) that could not be explicitly bound to physical cpus.
The first 3 patches are from Wen Congyang, which implement Cgroup for differrent
hypervisors.
The other 10 patches implemented hypervisor threads binding, in two ways:
1) Use sched_setaffinity() function;
2) Use cpuset cgroup.
A new xml element is introduced, and vcpupin command is improved, see below.
1. Introduce new xml elements:
<cputune>
......
<hypervisorpin cpuset='1'/>
</cputune>
2. Improve vcpupin command to support hypervisor threads binding.
For example, vm1 has the following configuration:
<cputune>
<vcpupin vcpu='1' cpuset='1'/>
<vcpupin vcpu='0' cpuset='0'/>
<hypervisorpin cpuset='1'/>
</cputune>
1) query all threads pining
# vcpupin vm1
VCPU: CPU Affinity
----------------------------------
0: 0
1: 1
Hypervisor: CPU Affinity
----------------------------------
*: 1
2) query hypervisor threads pining only
# vcpupin vm1 --hypervisor
Hypervisor: CPU Affinity
----------------------------------
*: 1
3) change hypervisor threads pining
# vcpupin vm1 --hypervisor 0-1
# vcpupin vm1 --hypervisor
Hypervisor: CPU Affinity
----------------------------------
*: 0-1
# taskset -p 397
pid 397's current affinity mask: 3
Note: If users want to pin a vcpu thread to pcpu, --vcpu option could no longer be omitted.
Tang Chen (9):
Enable cpuset cgroup and synchronous vcpupin info to cgroup.
Support hypervisorpin xml parse.
Introduce qemuSetupCgroupHypervisorPin and synchronize hypervisorpin
info to cgroup.
Add qemuProcessSetHypervisorAffinites and set hypervisor threads
affinities
Introduce virDomainHypervisorPinAdd and virDomainHypervisorPinDel
functions
Introduce virDomainPinHypervisorFlags and
virDomainGetHypervisorPinInfo functions.
Introduce qemudDomainPinHypervisorFlags and
qemudDomainGetHypervisorPinInfo in qemu driver.
Introduce remoteDomainPinHypervisorFlags and
remoteDomainGetHypervisorPinInfo functions in remote driver.
Improve vcpupin to support hypervisorpin dynically.
Wen Congyang (3):
Introduce the function virCgroupForHypervisor
Introduce the function virCgroupMoveTask
create a new cgroup and move all hypervisor threads to the new cgroup

[libvirt] Stored secrets seem to get corrupted
by Wido den Hollander
Hi,
On one of my systems I'm having troubles with my RBD storage backend.
At first I thought it was a problem with my code, but after trying the
same code on a second machine I'm a bit confused.
The problem is that the storage backend tries to retrieve the value of a
secret and base64 decode it, that fails.
My debug log shows:
debug : virStorageBackendRBDOpenRADOSConn:65 : Using cephx authorization
debug : virStorageBackendRBDOpenRADOSConn:75 : Looking up secret by
UUID: 322bccea-f2ed-4eae-a7e5-d0793ffb162d
debug : virSecretLookupByUUIDString:14128 : conn=0x7fac9c0009c0,
uuidstr=322bccea-f2ed-4eae-a7e5-d0793ffb162d
debug : virSecretLookupByUUID:14086 : conn=0x7fac9c0009c0,
uuid=322bccea-f2ed-4eae-a7e5-d0793ffb162d
debug : virSecretGetValue:14486 : secret=0x7fac94000d30,
value_size=0x7facad481918, flags=0
debug : virStorageBackendRBDOpenRADOSConn:103 : Found cephx key: `I^%
debug : virStorageBackendRBDOpenRADOSConn:135 : Found 1 RADOS cluster
monitors in the pool configuration
debug : virStorageBackendRBDOpenRADOSConn:159 : RADOS mon_host has been
set to: 31.25.100.131:6789,
error : virStorageBackendRBDOpenRADOSConn:171 : internal error failed to
connect to the RADOS monitor on: 31.25.100.131:6789,
It goes wrong at "Found cephx key: <garbage>"
So I figured it had to be something in my code and I went over the code
again, but nothing seemed odd.
I tried the same checkout (tag: 0.9.13-rc1) on a different host (also
Ubuntu 12.04) and that worked.
The secret and pool XML's are the same, but what I found is that the
secret storage on disk seems to go wrong on one machine.
Notice this behavior:

As you can see, the md5sum of the file changes when I set the value of
the secret to the same.
I tried the same on the other host:
root@stack02:~# virsh secret-set-value

root@stack02:~#
The md5sum stays the same on stack02.
I verified that stack01 isn't out of disk space or out of inodes, those
are in the acceptable values range.
Any suggestions?
For the record, the hosts:
OS: Ubuntu 12.04 x864_64
Kernel: 3.2.0-25-generic
