[libvirt] [PATCH 0/6] Introduce a new migration protocol to QEMU driver
by Daniel P. Berrange
The current migration protocol has several flaws
- No initial hook on the source host to do work before
the dst VM is launched
- No ability to restart src VM if dst fails to recv all
migration data, but src successfully sent it all
This introduces a new 5 step migration process to address
this limitation. To support features such as seemless
migration of SPICE clients, and lock driver state passing
this now makes use of the migration cookie feature too

Ah okay. The issue is that libvirt only advertises KVM if it finds a
file named qemu-kvm or kvm, so it won't by default allow using kvm with
a stock qemu release. You can probably work around this by symlinking
/usr/bin/qemu-kvm to /usr/bin/qemu-system-x86_64. Might want to file a
bug with your distro to do the same (or have them actually ship the
forked qemu that is distributed with KVM upstream, since it's generally
what receives the most testing).
The proper fix though is to have libvirt advertise KVM for upstream qemu
binaries if it finds the correct CLI arguments. We will probably need to
do this anyways when the KVM qemu fork is fully merged upstream.

[libvirt] [PATCH 0/3] Support for marking domains as "tainted"
by Daniel P. Berrange
There are various configurations for virtual domains that we allow,
but do not wish to actively support in production environments.
The support situation is similar to that of binary only or non-GPL
kernel modules, so borrow the kernel's idea of "tainting".
When an undesirable configuration is used on a running VM, set a
suitable taint flag and log a warning. OS distro bug triagers can
see these warnings and decide whether to support users filing bugs
in this scenarios

[libvirt] [PATCH] Fix qemuMigrationToFile nonull annotation
by Daniel P. Berrange
The qemuMigrationToFile method was accidentally annotated for
the 'compressor' parameter to be non-null, instead of the
'path' parameter. Thus GCC with -O2, unhelpfully deleted the
entire 'if (compressor == NULL)' block of code during
optimization. Thus NULL was passed to virCommandNew() with
predictably bad results.
* src/qemu/qemu_migration.h: Fix non-null annotation to be
against path instead of compressor
---
src/qemu/qemu_migration.h | 2 +-
1 files changed, 1 insertions(+), 1 deletions(-)
This shows that the 'ATTRIBUTE_NONNULL' annotation is actually
really very dangerous to use. GCC is incapable of issuing any
warnings about callers passing NULL, unless they pass a literal
"NULL". If the caller does 'void *p = NULL; foo(p)' it will not
warn. GCC is also not warning about the fact that there is a
huge block of code for 'if (compressor == NULL)' that is "dead"
code and being deleted.
While it is perhaps nice to have ATTRIBUTE_NONNULL for static
analysis tools like clang, IMHO, it is too dangerous for us
to continue to have it enabled in builds. I think we should
define it to a no-op macro, unless explicitly enabled with
configure.

[libvirt] Keep qemu capability data for each VM from startup
by Daniel P. Berrange
Currently, whenever we require QEMU capabilities data, we rerun
QEMU to extract the info. This isn't desirable because it is
inefficient and the QEMU binary may have changed since we started
the guest. This series makes us keep a copy of the capability
data around for lifetime of the VM process

Ok, I think the problem is your KVM version. You probably need
to make the /etc/libvirt/qemu.conf changes I mentioned, to get
it to work.

[libvirt] the guest killed itself
by guan qin
Hi,
I try to use VT-d, but meet with a strange problem .
I create a VM through "virsh create ***.xml",as follows:
root@shahe26:~# virsh create vt_d_debian.xml
Domain vt_d_debian created from vt_d_debian.xml
root@shahe26:~# virsh list
Id Name State
----------------------------------
4 vt_d_debian running
root@shahe26:~# virsh list
Id Name State
----------------------------------
4 vt_d_debian running
root@shahe26:~# virsh list
Id Name State
----------------------------------
4 vt_d_debian running
root@shahe26:~# virsh list
Id Name State
----------------------------------
4 vt_d_debian no state
root@shahe26:~# virsh list
Id Name State
----------------------------------
root@shahe26:~# vim vt_d_debian.xml
The VM has already killed itself.

[libvirt] [PATCH] maint: detect clang 2.9
by Eric Blake
In Fedora 15, with clang 2.8, 'scan-build env' shows:
CCC_ANALYZER_ANALYSIS=-analyzer-check-objc-mem -analyzer-check-security-syntactic -analyzer-check-dead-stores -analyzer-check-objc-unused-ivars -analyzer-check-objc-methodsigs
But in rawhide, with clang 2.9, the same variable is set but
empty, implying the default set of analysis. We still want
sa_assert defined in that case, to stop clang from hitting
false positives.
* configure.ac (STATIC_ANALYSIS): Detect clang even when the set
of analyses is the default.
---
I'm pushing this under the trivial rule. It has no effect on
a real build, but makes it easier for me to repeat my clang
testing on rawhide.
