Strange QoS behavior
Hi,
I'm having some weird problem with the setup of the QoS on a bridged network.
As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected).
Using 1280 units I get a speed og 5Mbps.
I'm aware of peak and

Changing QoS on-the-fly
Hi all,
it's possible to change/add the QoS settings for a running domain?
I edited the domain definition with virsh but it seems to have no effect until I shut down the domain.
libvirt version 0.9.13
kvm-qemu version 1.2.0
Best,
Davide.

Incremental Backups
Hello.
Is someone performing incremental backups via libvirt for qemu/kvm
machines? I'm still having a hard time to
find a nice procedure. I mean is it possible to make a full backup of an
image on monday a do the next days of the week
incremental backups?
Another way could be mount the image and rsync its contents. Does that
makes sense?
Also i read in qemu changelog:

Yeah. I saw that and tried this already. But it needs to be adjusted to
libvirtd-1.1.2 i think. Can you do this? I fiddled a litte bit around
but wasn't realy successfull.

[Feature Request] Allow options in Host block to override global options in ssh
Hi everyone,
For ssh(1) to override global options with the options in "Host" block, the
attached diff (w.r.t. the openssh code in FreeBSD 8.1-R) contains the code to
do so while parsing ssh configuration file.
This is useful for case like following where {d,proj,p,n}cvs.FreeBSD.org is an
alias to ncvs.FreeBSD.org hostname, thus connecting to
{d,proj,p,n}cvs.FreeBSD.org should utilize

Disk-only internal snapshot
Hi all,
it's possible to do an internal snapshot with the --disk-only option (for
qcow2 images)?
The following command
virsh snapshot-create-as my-dom my-snap my-description
creates an internal snapshot but the following
virsh snapshot-create-as my-dom my-snap my-description --disk-only
creates an external snapshot.
Thanks,
Davide.

Block device IO limits
Hi all,
is there a way to limit the throughput (or the number of operations per seconds) of a block device?
I ask because I've a couple of misconfigured VMs that are performing a lot of disk activity (swapping I'd bet but I haven't access to their OS). Since their storage is on a NFS share they are slowing down other VMs on the same share.
Thank you.
Davide.

Cisco VoIP QOS
I have currently following the instructions at-

I am using a Cisco 877 router with an ADSL2+ connection.
My upstream bandwidth is around 1Mbps, and my downstream around 4-5Mbps.
I have two PSTN side interfaces - atm0 and dialer0 (dialer0 is where the ISP
details are configured and the interface that the WAN side IP is applied on)

QoS in wireless networks
Hello,
I''m trying to configure several wireless routers with QoS support. The
idea is to implement differentiated services so that VoIP traffic gets
the maximal priority, then video, control traffic, interactive data
traffic and best-effort traffic.
I have seen that CBQ used to be chosen as qdisc for implementing
bandwith share in DiffServ but now HTB is preferred because it is

DCC rule set
I have been given a set of "firewall rules" to open my firewall for DCC
to support my spam filtering.
(I have done many web searches trying to find info relating to DCC with
Shorewall, to no avail.
The problem is that I am clueless on how these "rules" translate into
the shorewall rule format.
Could someone please help me translate these?

CRAN: How to list a non-Sweave doc under "Vignettes:" on package page?
Hi,
is it possible to have non-Sweave vignettes(*) in inst/doc/ be listed
under 'Downloads' on CRAN package pages? For instance, in my R.rsp
package I have a inst/doc/report.pdf (part of the source *.tar.gz)
that is not detected/listed. The PDF is not based on a Sweave
vignette but an *.tex.rsp vignette that is dynamically created via

QOS ip filter does no work with 2 queues below top level queue ...
Hello
First thanks for the answers I have received from the list!!
I have now a working qos configuration which bases of the lartc howto

One Problem I have is that I have limited the upload stream to 100kps
because my
upstream is only 128kbps.
Everything works fine EXCEPT Voip.
I have a VoiP phone which is connected on the same net as the adsl modem BUT

QoS + OpenVPN
Hi, I''ve got 3 questions:
1) is it possible to do QoS and OpenVPN? I thought about doing QoS based
on IP, as there''s a couple of servers here that need to be on a higher
priority.
2) can anyone point me to a decent QoS how-to?
3) damn, I can''t remember what this one was. :o)

Validating QoS
Hi all,
I have been tasked with "implementing QoS" on one of our networks.
Looking at the documents of LARTC I believe I can implement most of
what we want just using netfilter rules and tc. So far, so good.
My question though is how can I analyse how much of an improvement I
can expect to achieve using these kinds of solutions. Does anyone here
have any experiences that they can share

QoS IP precedence and Diffserv combination
All:
I am tasked with creating an environment in which DiffServ and IP
precedence is handled as close to RFC specification as possible. I have
a few problems with implementing this based on current queueing
structure. Here are a few of my questions.
1.) Is there any way to get DiffServ AF drop levels without using
DSMARK and GRED?
Ex.
AF11 Gred DP 1
AF12 Gred DP 2
AF13 Gred DP 3
2.)
