[libvirt] [PATCH] Unify *ReportError logic
by Cole Robinson
Currently, most src/* files have their own ReportError
function. Some support printf style arguments, others
only allow reporting a single string message. The code
for all of them does virtually the same thing, possibly
passing a different constant off to another function.
The attached patch adds a function to virterror.c which
encapsulates the common ReportError logic. I used this
to replace qemudReportError with a macro, which also
allows passing off filename and line number info if
we wanted to do something with it later.
I did just the one function conversion to see what
people think: if I'm missing something, or ideas for
anything else to add. Seems to work as expected in
my testing.
Thanks,
Cole

[libvirt] first argument in virDomainMigrate, is it free'ed?
by Stefan de Konink
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Hi,
I saw that freeing the dom after a migration takes place results in:
libvir: Domain error : invalid domain pointer in virDomainFree
Now I wonder, if this is the case, could a normale migrate function
'just' be:
domain = virDomainMigrate(domain, ....)
Or is this unsafe; for example as a domain migration fails?

[libvirt] [PATCH] Add generic parameter=value support for virsh's schedinfo command
by Dan Smith
This patch maintains the two Xen-specific --weight and --cap options,
but adds support for setting arbitrary parameters by specifying them in
param=value syntax.
Changes to the virsh manual are included.
Changes:
- Replace use of 'a' conversion modifier with pre-alloc

[libvirt] [PATCH] Reboot support for QEMU/KVM
by Eduardo Habkost
This patch implements reboot support on qemu_driver.
It is so simple that I am wondering if there is some problem I am missing,
that would be the reason it wasn't implemented yet. I hope not. :)
