[libvirt] [PATCH] rbd: Use rbd_create3 to create RBD format 2 images by default
by Wido den Hollander
This new RBD format supports snapshotting and cloning. By having
libvirt create images in format 2 end-users of the created images
can benefit of the new RBD format.
Older versions of libvirt can work with this new RBD format as long
as librbd supports format 2, something that all recent versions of
librbd do.

[libvirt] [uq/master PATCH 0/7] x86 CPU subclasses, take 7
by Eduardo Habkost
Is there any hope to get this into QEMU 2.0, or it is now too late? I got
almost no feedback on take 6 (submitted November 27).
This is the main blocker to allow libvirt finally implement an equivalent to the
"enforce" flag, finally making the CPU configuration safe and sane (today
libvirt simply ignores GET_SUPPORTED_CPUID information, and features are
silently disabled because "enforce" is not used).
This blocks libvirt because the current available interfaces requires re-running
QEMU for each CPU model to be probed. Having the x86 CPU subclasses allow
libvirt to simply create and destroy CPU objects from each available CPU class,
and query for the results using QMP.
Demonstration of how this can be used, below:
Running QEMU as:
$ qemu-system-x86_64 -enable-kvm -machine none -monitor stdio -qmp unix:/tmp/qmp,server,nowait -nographic
Then running qmp-shell as:
$ ./scripts/qmp/qmp-shell /tmp/qmp

Changes from take 6:
* Rebase against uq/master
* Patch 1/7:
* Check for __i386__ on host_cpuid() so the code compiles properly
on non-x86 hosts.
Suggested-by: Paolo Bonzini <pbonzini(a)redhat.com>
* Don't add assert(kvm_enabled()) line, which is not necessary to help
the compiler (and wouldn't help it if using -DNDEBUG, anyway).
Reported-by: Richard Henderson <rth(a)twiddle.net>
* Commit message update
Eduardo Habkost (7):
target-i386: Eliminate CONFIG_KVM #ifdefs
target-i386: Don't change x86_def_t struct on cpu_x86_register()
target-i386: Move KVM default-vendor hack to instance_init
target-i386: Rename cpu_x86_register() to x86_cpu_load_def()
target-i386: Call x86_cpu_load_def() earlier
target-i386: Rename x86_def_t to X86CPUDefinition

[libvirt] [PATCHv2] build: correctly check for SOICGIFVLAN GET_VLAN_VID_CMD command
by Laine Stump
In order to make a client-only build successful on RHEL4, commit
3ed2e54 modified src/util/virnetdev.c so that the functional version
of virNetDevGetVLanID() was only compiled if GET_VLAN_VID_CMD was
defined. However, it is *never* defined, but is only an enum value, so
the proper version was no longer compiled even on platforms that
support it. This resulted in the vlan tag not being properly set for
guest traffic on VEPA mode guest macvtap interfaces that were bound to
a vlan interface (that's the only place that libvirt currently uses
virNetDevGetVLanID)
Since there is no way to compile conditionally based on the presence
of an enum value, this patch modifies configure.ac to check for said
enum value with AC_CHECK_DECLS(), which #defines HAVE_GET_VLAN_VID_CMD
if it's successful compiling a test program that uses
GET_VLAN_VID_CMD. We can then make the compilation of
virNetDevGetVLanID() conditional on that #define instead.
---
Difference from V1:
Use the amazingly compact AC_CHECK_DECLS() instead
of deprecated AC_TRY_COMPILE() + extra trappings.

[libvirt] [PATCH RFC 2/2] support configuring the format of dumping memory in qemu.conf
by Qiao Nuohan
This patch is used to add dump_memory_format to qemu.conf and make the
specified format as the default dump format of 'virsh dump --memory-only'.
But when "--compress" is specified with dump command, the format configured
by dump_memory_format will be overrided. dump_memory_format can one of elf,
kdump-zlib, kdump-lzo and kdump-snappy. And elf is the default value.

[libvirt] [PATCH] build: correctly check for SOICGIFVLAN GET_VLAN_VID_CMD command
by Laine Stump
In order to make a client-only build successful on RHEL4, commit
3ed2e54 modified src/util/virnetdev.c so that the functional version
of virNetDevGetVLanID() was only compiled if GET_VLAN_VID_CMD was
defined. However, it is *never* defined, but is only an enum value, so
the proper version was no longer compiled even on platforms that
support it. This resulted in the vlan tag not being properly set for
guest traffic on VEPA mode guest macvtap interfaces that were bound to
a vlan interface (that's the only place that libvirt currently uses
virNetDevGetVLanID)
Since there is no way to compile conditionally based on the presence
of an enum value, this patch modifies configure.ac to check for said
enum value with AC_TRY_COMPILE(), and #defines HAVE_GET_VLAN_VID_CMD
if it's successful compiling a test program that uses
GET_VLAN_VID_CMD. We can then make the compilation of
virNetDevGetVLanID() conditional on that #define instead.

[libvirt] [PATCH] virNetworkLoadState: Disallow mangled 'floor' element
by Michal Privoznik
In the network status XML we may have the <floor/> element with the
'sum' attribute. The attribute represents sum of all 'floor'-s of
computed over each interface connected to the network (this is needed to
guarantee certain bandwidth for certain domain). The sum is therefore a
number. However, if the number was mangled (e.g. by an user's
interference to network status file), we've just ignored it without
refusing to parse such file. This was all due to 'goto error' missing.
