Hi Daniel and other developers,
We have programed a HLFS(HDFS based Log-Structured FileSystem)
driver for QEMU, which you can see it here.
http://cloudxy.googlecode.com/svn/trunk/hlfs/patches/hlfs_driver_for_qemu_1.3.0.patch
And i have tested in QEMU environment, which works well for us.
Now, we

1. git clone git://git.qemu.org/qemu.git
2. cd qemu
3, git reset --hard v1.3.0
4, ./configure
5, make
6, sudo make install
After step 6, i did following jobs.

This is a stupid mistake, which the latter one is *NOT* installed by
the first one. Jackson, thanks for your suggestions ;-)

HI all :
I write a new block driver based on hdfs of hadoop, it need to
connect to hdfs when create step (called by bdrv_create in block.c) by
use libhdfs ( hdfs c++ api) 。
libhdfs use jni api to will create jvm . The problem is —— it
will cause sigsegv error when create jvm .

HLFS is HDFS-based(Hadoop Distributed File System) Log-Structured File
System. Actually, HLFS, currently, is not a FS but a block-storage system,
which we simplify LFS to fit block-level storage. So you could also call HLFS
as HLBS (HDFS-based Log-Structured Block-storage System).

Hi all,
I wanna add a new block storage driver by Libvirt/Qemu way for Openstack, which
is as same as Sheepdog driver for Openstack. So i think the theories
are like this.
1, In the Openstack Nova branch, Openstck driver call libvirt client
and send parameters
to libvirt client.(From this point,

Hi all,
We programmed a block storage(HLFS) patch for QEMU. Therefore,
when i patched this driver for QEMU, it happened to me some errors.
Could anyone give me some suggestions, thanks in advance ;-)

Hi all,
We add new entries for qemu/configure(QEMU v1.3.0), which
can locate our libraries and header files to compile our driver
for QEMU. The new entries in qemu/configure are like following.

Hi all,
When i debug our block driver in QEMU source codes, i cannot
find the debug logs for QEMU. I have searched /var/log/messages
and /var/log/dmesg but i cannot find debug logs.
Could anyone tell me how to find debug logs? Thanks in advance ;-)
