[libvirt] [PATCH] Fix compilation of legacy xen driver with Xen 4.2
by Jim Fehlig
In Xen 4.2, xs.h is deprecated in favor of xenstore.h. xs.h now
contains
#warning xs.h is deprecated use xenstore.h instead
#include <xenstore.h>
which fails compilation when warnings are treated as errors.
Introduce a configure-time check for xenstore.h and if found,
use it instead of xs.h.

[libvirt] [PATCH] Network: LXC generic ethernet interface
by Takayuki Usui
The patch adds generic ethernet type to LXC, that allows you to make
an arbitrary virtual network interface and associate it to an LXC
domain. That does not, however, provide a means to execute a script,
that is still available only for QEMU.
1. Create a virtual ethernet device pair
# ip link add type veth (e.g. veth0 and veth1 by default)
2. Define a LXC domain and associate it to one end of the pair
[...]
<interface type='ethernet'>
<target dev='veth1'/>
</interface>
3. Do whatever you like, for example, add another end of the pair
to a bridge (e.g. br0)
# brctr addif br0 veth0
# ip link set dev veth0 up
4. Start a LXC domain. The interface shows up as eth0 in the domain.

[libvirt] [PATCH] Fix dnsmasq/radvd on bridges not being able to be bound to IPv6 address on "recent" kernels
by Benjamin Cama
Hi,
I hit this problem recently when trying to create a bridge with an IPv6
address on a 3.2 kernel: dnsmasq (and, further, radvd) would not bind to
the given address (resp. interface), waiting 20s and then giving up with
-EADDRNOTAVAIL (resp. exiting immediately with "error parsing or
activating the config file", without libvirt noticing it, BTW). This can
be reproduced with (I think) any kernel >= 2.6.39 and the following XML
(to be used with "virsh net-create"):
<network>
<name>test-bridge</name>
<bridge name='testbr0' />
<ip family='ipv6' address='fd00::1' prefix='64'>
</ip>
</network>
(it happens even when you have an IPv4, too)
The problem is that since commit [1] (which, ironically, was made to
“help IPv6 autoconfiguration”) the linux bridge code makes bridges
behave like “real” devices regarding carrier detection. This makes the
bridges created by libvirt, which are started without any up devices,
stay with the NO-CARRIER flag set, and thus prevents DAD (Duplicate
address detection) from happening, thus letting the IPv6 address flagged
as “tentative”. Such addresses cannot be bound to (see RFC 2462), so
dnsmasq fails binding to it (for radvd, it detects that "interface XXX
is not RUNNING", thus that "interface XXX does not exist, ignoring the
interface" (sic)). It seems that this behavior was enhanced somehow with
commit [2] by avoiding setting NO-CARRIER on empty bridges, but I
couldn't reproduce this behavior on my kernel. Anyway, with the “dummy
tap to set MAC address” trick, this wouldn't work.
To fix this, the idea is to get the bridge's attached device to be up so
that DAD can happen (deactivating DAD altogether is not a good idea, I
think). Currently, libvirt creates a dummy TAP device to set the MAC
address of the bridge, keeping it down. But even if we set this device
up, it is not RUNNING as soon as the tap file descriptor attached to it
is closed, thus still preventing DAD. So, we must modify the API a bit,
so that we can get the fd, keep the tap device persistent, run the
daemons, and close it after DAD has taken place. After that, the bridge
will be flagged NO-CARRIER again, but the daemons will be running, even
if not happy about the device's state (but we don't really care about
the bridge's daemons doing anything when no up interface is connected to
it).
Other solutions that I envisioned were:
* Keeping the *-nic interface up: this would waste an fd for each
bridge during all its life. May be acceptable, I don't really
know.
* Stop using the dummy tap trick, and set the MAC address directly
on the bridge: it is possible since quite some time it seems,
even if then there is the problem of the bridge not being
RUNNING when empty, contrary to what [2] says, so this will need
fixing (and this fix only happened in 3.1, so it wouldn't work
for 2.6.39)
* Using the --interface option of dnsmasq, but I saw somewhere
that it's not used by libvirt for backward compatibility. I am
not sure this would solve this problem, though, as I don't know
how dnsmasq binds itself to it with this option.
This is why this patch does what's described earlier. I see radvd
yelling quite often in the logs when the interface is NO-CARRIER, but
it's ok, it keeps running.
Still, this patch is not exactly correct, as radvd get daemonized “too
soon” most of the time (i.e. when not debugging libvirtd…) and probes
the bridge once it has been set down (even if started before setting it
down), thus failing as before (and libvirt lets it be like that: this
would need some more checking, maybe). One /may/ introduce some delay
between networkStartRadvd() and setting the dummy tap down to solve it,
but it seemed too hackish to me. But I couldn't come with a better
solution. I would welcome suggestions here.
BTW, I removed the “up” argument from virNetDevTapCreateInBridgePort()
and virNetDevTapCreate() as all TAP devices are created up now, and I
fixed a function name in the docstring.

This patch fixes incorrect help screen parsing for QEMU 1.0.1 package
Version line changed from
QEMU emulator version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard
To
QEMU emulator version 1.0,1 (qemu-kvm-1.0.1), Copyright (c) 2003-2008 Fabrice Bellard
Comma in version number hits parsing logic and leads to incorrect capabilities list.
Particularity KVM support capability is not detected making problems in various scenarious.
The patch treats the newly added 1 as a micro version number, not sure this is legitimate.
Please, correct me if I'm wrong.
