[libvirt] [PATCH 0/2 v2] Colorize HTML documentation
by Claudio Bley
The only difference to v1 is that I fixed the CSS pseudo elements
adding some vital whitespaces.
(I tried to be extra smart and removed some whitespace without further
testing, just to discover that it did not work anymore *after*
sending the patcheset).

[libvirt] [PATCH 00/12] virsh: Partially convert to c99 struct initialization

For now, we have to suffice with vshCmdOptDef. Others coming soon.
Changes are pretty mechanical, so if you find a mistake there,
blame my vim macro :)

[libvirt] [PATCH] Move comment after enum members
by Claudio Bley
The api builder always associates comments to the last member it read,
not to the current member even if there was a comment for the previous
member and a comma was already seen.
This has the effect that the comment for the previous member gets
overwritten and the current member has no comment at all.

[libvirt] iptables --physdev-out warnings
by Reinier Schoof
Hi,
we've experienced some issues with starting lots of KVM based VM's with
libvirt. Since I couldn't find any clues on the libvirt mailing list,
I'm posting the way I fixed the issues.
When starting a VM, /var/log/messages was spammed with the following
message:
xt_physdev: using --physdev-out in the OUTPUT, FORWARD and POSTROUTING
chains for non-bridged traffic is not supported anymore.
With each extra VM I start, the messages get amplified exponentially.
This results in longer starting times every new VM, relative the the
previously started VM. When I ran a test with starting 100 equal VM's,
the first VM started in about 2 seconds, the 100th VM took 48 seconds to
start. I'm running a vanilla 3.7.1 kernel, but I have the same issue on
VM hosts with kernel 3.2.28 or 3.2.0, running libvirt 0.9.12 and 0.9.8
respectively.
Looking into the warning, it seemed that iptables need an extra
argument, --physdev-is-bridged, in commands like:
iptables -A libvirt-out -m physdev --physdev-is-bridged --physdev-out
vnet99 -g FP-vnet99
I patched the libvirt source (version 1.0.0) to test whether this works
or not:

static const char *m_state_out_str = "-m state --state NEW,ESTABLISHED";
static const char *m_state_in_str = "-m state --state ESTABLISHED";
The warnings in /var/log/messages are gone and running the test again
proved the 100th VM started in 3.8 seconds. It suprises me I'm the first
to mention this problem on the libvirt mailing list and I wondering if
I'm doing something wrong. Until then, this fix helps me a lot!

[libvirt] [test-API][PATCH] Add storage cases of pool list, pool lookup and volume lookup
by Wayne Sun
Add 3 simple storage realted API cases
* pool_list_active is only for testing with flags:
libvirt.VIR_CONNECT_LIST_STORAGE_POOLS_ACTIVE
* pool_lookup is for testing lookup pool object by name, UUID,
UUIDString and volume object
* vol_lookup is for testing lookup volume object by name, key
and path
* add cases into storage_dir.conf

[libvirt] [PATCH v2 0/5]use VIR_ENUM_DECL for domain NIC model and add usb-net
by Guannan Ren
v1 to v2
*removed i8* NIC models support for QEMU/KVM
*updated docs
This patchset uses VIR_ENUM_DECL and VIR_ENUM_IMPL macros for NIC models
and changes the related codes to use them.
All of NIC models supported by various hypervisors comprise the enum,
so the problem is that we need to do further checking in hypervisor-specific
implementation. Fortunately, VMX and Vbox did this checking very well already.
In 4/5, a similar job is performed for QEMU/KVM.
And, adds usb-net support.
The vendorId and productID of is 0525:a4a2. The corresponding item in
usb-ids is as follows:
0525 Netchip Technology, Inc.
a4a2 Linux-USB Ethernet/RNDIS Gadget
In my opinion, using usb-net directly is good enough, so I keep it.
Any idea is welcome.
