People have been confused about this in the past, so document that
vnet and vif are reserved names and will be ignored if manually specified.

[libvirt] [PATCH] 514532 Fix man page, most operation are synchronous
by Daniel Veillard
As pointed in https://bugzilla.redhat.com/show_bug.cgi?id=514532
we were historically warning about operation being asynchronous
in the man page but actually most operations are synchronous.
I still kept a warning about domain creation and shutdown, maybe
we should add a few more, but as is this is mostly correct and
better than the current description IMHO
Maybe we should flag formally in the description all APIs which
have an asynchronous behaviour.
514532 Fix man page, most operation are synchronous
* tools/virsh.pod: the man page was stating that most operations
are asynchronous while in fact most of them are synchronous except
domain creation and shutdown

[libvirt] [PATCH] Check for duplicated UUID in XM Xen defines
by Daniel Veillard
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=504262
where the xen drivers happily allows to define domains with conflicting
UUID. This is similar to the virDomainObjIsDuplicate check done in other
drivers but the internal structures are different so this need to be
done in a special way
Author: Daniel Veillard <veillard(a)redhat.com>
Date: Tue Nov 17 12:06:46 2009 +0100
504262 Check for duplicated UUID in XM Xen defines
* src/xen/xm_internal.c: the XM driver was not checking for previously
defined UUID on new defines. Similar to virDomainObjIsDuplicate()
behaviour.

512069 fix domain XML schemas for backward compatibility
For backward compatibility we used to add the tty path as
a tty attribute on console of type pty, duplicating the value
now found in source/@path, but the Relax-NG grammar wasn't
extended for this
<console type='pty' tty='/dev/pts/8'>
<source path='/dev/pts/8'/>
<target port='0'/>
</console>

[libvirt] PATCH: recent qemu-kvm requires -enable-kvm flag to activate VT optimization
by Steve Yarmie
Hello,
Recent qemu releases require command option '-enable-qemu' in order
for the kvm functionality be activated. Libvirt needs to pass this
flag to qemu when starting a domain. Note that without the option,
even if both the kernel and qemu support KVM, KVM will not be activated
and VMs will be slow as molasses ;)
I added a check in qemu_conf.c to see if `qemu -help` emits the -enable-kvm
flag, and if so, use the flag accordingly.
There exists a check in src/qemu/qemu_conf.c to check for the -no-kvm flag.
This check works the same way.
Adding the included code will not break systems where qemu does not
have the option.
See 'qemu -help':
...
-enable-kvm enable KVM full virtualization support
...
included patch against src/qemu/qemu_conf.{c,h}
