[libvirt] [PATCH] Storage: Fix allocation for raw files.
by Prerna Saxena
When virsh vol-clone is attempted on a raw file where capacity > allocation,
the resulting cloned volume has a size that matches the virtual-size of
the parent; in place of matching its actual, disk size.
For example : Given this image:
[root@localhost]# qemu-img info /var/lib/libvirt/images/f20.raw
image: /var/lib/libvirt/images/f20.raw
file format: raw
virtual size: 2.0G (2147483648 bytes)
disk size: 617M
When this disk is copied using virsh vol-clone :
[root@localhost~] vol-clone --vol f20.raw --newname f20-copy.raw
--pool default
Vol f20-copy.raw cloned from f20.raw
[root@localhost~]
The characteristics of the cloned disk differ in "disk size".
Its allocated disk size is more than the allocated size of parent file;
which is an anomaly. It has picked up an allocated size matching
the parent's virtual size.
[root@localhost~] qemu-img info /var/lib/libvirt/images/f20-copy.raw
image: /var/lib/libvirt/images/f20-copy.raw
file format: raw
virtual size: 2.0G (2147483648 bytes)
disk size: 2.0G
This patch fixes the cloned disk to have same _allocated_size_ as
the parent file from which it was cloned.

Commit 0e1a1a8c introduced umask for virCommand, but the variables
used emit a warning on older compilers about shadowed global

[libvirt] [PATCH V2] fix: unix sockets created for virtio-serail has insufficient permissions
by Chunyan Liu
Add umask to _virCommand, allow user to set umask to command.
Set umask(002) to qemu process to overwrite default umask(022) so
that unix sockets created for virtio-serial has expected permissions.
Fix problem reported here:
https://sourceware.org/bugzilla/show_bug.cgi?id=13078#c11
https://bugzilla.novell.com/show_bug.cgi?id=888166
To use virtio-serial device, unix socket created for chardev with
default umask(022) has insufficient permissions.
e.g.:
-device virtio-serial \
-chardev socket,path=/tmp/foo,server,nowait,id=foo \
-device virtserialport,chardev=foo,name=org.fedoraproject.port.0
srwxr-xr-x 1 qemu qemu 0 21. Jul 14:19 /tmp/somefile.sock
Other users in the same group (like real user, test engines, etc)
cannot write to this socket.
Signed-off-by: Chunyan Liu <cyliu(a)suse.com>

Changes:
* set umask(002) to the whole qemu process instead of calling
umask in qemu unix_listen_opts.

[libvirt] [PATCH v1 0/6] ivshmem support
by Maxime Leroy
The following patches are an implementation of
a new shmem device to support ivshmem in libvirt.
Any feedback is welcome.
Changes since RFC:
- replace <ivshmem> by a more generic term <shmem>
- remove role attribute
- libvirt is able to start and stop an ivshmem server
- update xml format from:
<ivshmem use_server='yes' role='master'>
<source file='/tmp/socket-ivshmem0'/>
<size unit='M'>32</size>
<msi vectors='32' ioeventfd='on'/>
</ivshmem>
to:
<shmem name='shmem0' model='ivshmem'>
<server path='/tmp/sockect-ivshem0' start='yes'/>
<size unit='M'>32</size>
<msi vectors='32' ioeventfd='on'/>
</shmem>
Maxime Leroy (6):
doc: schema: Add documentation for the shmem support
conf: Parse and format shmem device XML
qemu: Add cap flag QEMU_CAPS_IVSHMEM
qemu: Build command line for ivshmem device
tests: Add tests for ivshmem device handling
ivshmem: add start param to server attribute
