cputune shares with multiple cpu and pinning
Hi,
I have found the cpu time partitioning based on cpu shares weights not
very intuitive.
On RHEL64, I deployed two qemu/kvm VMs
VM1 with 1 vcpu and 512 cpu shares
VM2 with 2 vcpus and 1024 cpu shares
I pinned their vcpus to specific host pcpus:
VM1 vcpu 0 to host pcpu1
VM2 vcpu 0 to host pcpu1, VM2 vcpu 1 to host pcpu2
I executed inside the VMs a simple process that consume all

picking a NUMA cell for pinning using virsh freecell
Hi
I'd want to pin the vcpu of a guest to a pcpu.
the docs clearly say
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/ch09s04.html
"Locking a guest to a particular NUMA node offers no benefit if that node
does not have sufficient free memory for that guest. libvirt stores
information on the free memory available on

can virsh set the cpuset attribute of <vcpu ..> (CPU Allocation) ?
Is it possible to use virsh to set the cpuset attribute of the CPU
Allocation element in a domain ?
<domain>
...
<vcpu placement='static' cpuset="1-4,^3,6" current="1">2</vcpu>
...
</domain>
I have seen that virsh vcpupin and virsh emulatorpin can be used to query
and set
the cpusets of the <vcpupin> and <emulatorpin>

Using a shared LVM volume group for both virtual disks and host filesystems
Hi
I have a test environment where a single LVM volume group is used
both as a storage pool for virtual machines' disks AND for the LVs used
for the HOST system filesystem.
I never use libvirt commands to start/stop/activate the pool. Only to
create/delete volumes.
The test environment works fine.
How suitable would be a shared VG for a production environment ?
thanks,

guest daemon reading kvmclock - is it not needed or bad idea ?
Hi
(apologies for the previous post in html - was scrubbed in the list
digest)
I've dug various posts and articles on host-guest time synchronization.
I could not conclude why it might be better to use ntpd in a guest rather
than a daemon that reads from kvmclock
and having NTP running on the host only

DVD Shrink and wine 20050111 vs 20041019
hallo
i'm running mepis (debian unstable) and if i install wine from the
regular (non-wine specific) deb repositories, I get wine 20041019.
if I install from wine.sourceforge, I get 200501011.
with the former, the application seems to lock up much more often.
with the latter, the ability to play the movie (e.g. to see which audio
stream to include) is disabled.

adding winehq debian repository to apt-get | synaptic
I added the winehq debian repository to apt-get | synaptic
(I am running mepis 3.3) and would like to install those rather than the
debian official unstable builds
but
since the winehq repository is also marked as part of 'unstable' distro
I can't find a way to distinguish the wine / winelib provided by winehq
from the official ones (which would need the many winelib-* packages)

I would need some help in building R using minGW in windows 8.1. After

CDR billsec greater than duration
Hi all,
I have a strange situation on a Asterisk 1.2.17 with FreePBX 2.2.1
Doing a select in the CDR table I noticed there are some calls with
billsec greater than duration, duration is always 0 in those calls.
How can this happens ? Am I missing something ?
Tnx in advance

running an icecast server
Hello everyone,
I'm in the process of running an Icecast server and I would like to know
some best pratices.
1. Should I place Icecast on port 8000 or should I change that to one more
common (80, 443...)?
2. Should I place the server behind a webserver like ngingx or apache?
3.Can I disable the login interface? what can be disabled?
My best guess is to run icecast behind a webserver,

Sponsored development - Monodirectional audio handling
Hi Guys,
we're needing a special implementation on Asterisk
Our intention is to contribute the development and share back the code
to Asterisk community
Here is what we need:
- An option to Asterisk Dial command which, if used, when calls is
answered gives monodirectional audio
(Caller should hear the called party but not vice-versa)
- A DTMF sequence (maybe handled in features.conf) for

syslinux.efi pxeboot across multiple subnets
The same client was used for syslinux.efi (both success on same subnet and
failure on different subnet) and grub.efi. The DHCP host block is setup
like:
host testing {
hardware ethernet {mac} ;
next-server 10.16.195.178 ;
filename "rhel64/syslinux.efi" ;
}
I'll pull a tcpdump filtering by the IP tomorrow when I get back to the
systems.

SIP/IAX peers UNREACHABLE and audio loss
Hi all,
I'm having a problem with some Asterisk servers interconnected with
each other using IAX (I also tried with SIP without solving the problem)
Sometimes, with apparently no reason, some peers become UNREACHABLE
(I have qualify=yes in iax.conf) and REACHABLE again as soon as
another qualify test is made.
Our users are also complaining about audio loss during their calls,
