[libvirt] [PATCH 1/2] blkiotune: add support for device iops and bps throttle
by hzguanqiang@gmail.com
From: Guan Qiang <hzguanqiang(a)corp.netease.com>
This adds per-device iops and bps throttle to <blkiotune>. By
extending the existed 'domainSetBlkioParameters' interface,
read/write iops and bps throttle for per-device can be set
with blkio cgroup. The blkiotune xml entry is now looked like:
<domain ...>
<blkiotune>
<device>
<path>/path/to/block</path>
<weight>1000</weight>
<read_bps>100000</read_bps>
<write_bps>100000</write_bps>
<read_iops>100000</read_iops>
<write_iops>1000000</write_iops>
</device>
</blkiotune>
..
Elments <weight>,<read_bps>,<write_bps>,<read_iops>,<write_iops>
are all optional, but must have one.

[libvirt] [PATCHv5 0/3] VMX: CD-ROM handling improvements
by Doug Goldstein
A user came into #virt the other day and was trying to get libvirtd
to work with VMware Fusion 5, which is basically the Mac OS X version of
VMware Workstation. In helping him out I noticed a few limitations of our
VMX parser so I've added support through this patchset. I don't personally
have access or own VMware's product.
v5:
* use virBufferEscapeString NULL handling instead of doing my own checks
* merge v4's patch 1 into master
* 2 & 3 of this series are unchanged and ACK'd from v4.
v4:
* Half the patchset has been merged at this point
* Add back 'auto detect' support via <source startupPolicy='optional'/>
* Made device='lun' match device='cdrom'
* Patch 1 & 2 are new to the series
v3:
* Dropped 'auto detect' support from series as it needs more work based on
feedback
* Added patch to combine virVMXFormatHardDisk and virVMXFormatCDROM into
one function.
* Converted to <disk type='block' device='lun'> instead of adding a
<driver> element to better match the behavior available via QEMU.
v2:
* Added additional test cases and fixed issues that arose from those
*** BLURB HERE ***
Doug Goldstein (3):
Allow <source> for type=block to have no dev
VMX: Add support for 'auto detect' fileNames
VMX: Add a VMWare Fusion 5 configuration for tests

[libvirt] [PATCH 4/5] blkiotune: add support for device iops and bps throttle
by hzguanqiang@gmail.com
From: Guan Qiang <hzguanqiang(a)corp.netease.com>
This adds per-device iops and bps throttle to <blkiotune>. By
extending the existed 'domainSetBlkioParameters' interface,
read/write iops and bps throttle for per-device can be set
with blkio cgroup. The blkiotune xml entry is now looked like:
<domain ...>
<blkiotune>
<device>
<path>/path/to/block</path>
<weight>1000</weight>
<read_bps>100000</read_bps>
<write_bps>100000</write_bps>
<read_iops>100000</read_iops>
<write_iops>1000000</write_iops>
</device>
</blkiotune>
..
Elments <weight>,<read_bps>,<write_bps>,<read_iops>,<write_iops>
are all optional, but must have one.

[libvirt] [PATCH 3/5] Add tftp protocol support for cdrom disk
by hzguanqiang@gmail.com
From: Aline Manera <alinefm(a)br.ibm.com>
qemu/KVM also supports a tftp URL while specifying the cdrom ISO image.
The xml should be as following:
<disk type='network' device='cdrom'>
<source protocol='tftp' name='/url/path'>
<host name='host.name' port='69'/>
</source>
</disk>
Signed-off-by: Aline Manera <alinefm(a)br.ibm.com>

[libvirt] [PATCH 2/5] Add ftps protocol support for cdrom disk
by hzguanqiang@gmail.com
From: Aline Manera <alinefm(a)br.ibm.com>
The ftps protocol is another protocol supported by qemu/KVM while specifying
the cdrom ISO image.
The xml should be as following:
<disk type='network' device='cdrom'>
<source protocol='ftps' name='/url/path'>
<host name='host.name' port='990'/>
</source>
</disk>

[libvirt] Can I request a new release of libvirt-java?
by Wido den Hollander
Hello,
In the recent months various new methods were added to libvirt-java
which we (Apache CloudStack) would like to use in our KVM code.
For example resizing storage volumes, right now we have to do this with
Bash scripting since although libvirt supports resizing volumes, the
current release (0.4.9) of libvirt-java doesn't.
I don't know if there are any objections, but if possible I'd like to
see 0.5.0 released so we get this new functionality for CloudStack.
We use maven for building CloudStack and it fetches libvirt-java from
libvirt.org/maven2
Thank you,
Wido den Hollander
