Hotplug/hotadd functionality of libvirt?
Hello,
First of all, happy new year!
I am interested in the hot plugging facilities of libvirt, in particular
in what qemu calls 'hot add' of network interface cards. (And also the
reverse: hot unplugging/removing of NICs.)
I think I am overlooking something, but so far the best I have been able
to find is:

and it is not entirely clear

Faulty manual?
Hi,
Look under examples:

pci:0000.00.11.0 --persistent
*error: command 'attach-disk' doesn't support option --address*
(root at h2)-(/)# virsh --version
0.7.5
Is someone playing a trick on me?
Regards,

quick question on schedinfo
Hey everyone,
Can anyone explain the scedinfo parameters? I am wondering if I can use
this, (along with host side niceness scheduler tweaks) to cause vCPUs to
dominate the total time of the CPUs they are pinned to.
Here are the sched info parameters:
Scheduler : posix
cpu_shares : 0
vcpu_period : 0
vcpu_quota : 0
emulator_period: 0

maxvcpus
Hi list,
According to the libvirt documentation [1]
"Show maximum number of virtual CPUs for guest domains on this connection"
This may not be a complete definition.
My first guess from the above was that this returns the number of virtual
CPUs that can exist at the same time on the host, either one or several
VMs. In fact it returned 16 in my fedora 20 desktop running with KVM,

The maxdowntime is probably too low for the migration to complete. Try
setting it to a higher value :
virsh migrate-setmaxdowntime <domain> <seconds>
Please tell me if it worked.

Editing http://libvirt.org/sources/virshcmdref/html-single/#sect-attach-device
I just noticed the entries on attach-disk and attach-devices are
a bit on the empty size. As I am just attaching a usb device to one of
my vm clients, I was wondering if I could offer examples to those
entries.

Migrate hangs at 99%
Hello guys!
We have a lot of virtual machines and I recently tried out the migrate
feature of libvirt.
It works like a charm, even without shared storage, but when we try to
migrate a VM under a little pressure (a HTTP server gets some 1-5
requests/sec) the migration process hangs at 99%.
After we stop the stressing of the VM, the migration immediately finishes.
I'm using the following

nested for() loops for returning a nearest point
I'm trying to do the following:
For each ordered pair of a data frame (D1) containing longitudes and
latitudes and unique point IDs, calculate the distance to every point in
another data frame (D2) also containing longitudes, latitudes and point
IDs, and return to a new variable in D1 the point ID of the nearest
element of D2.

Re: Easy solution for custom firewall rules- is it possible?
Hi,
libvirts nwfilter module can achieve that.
I'm currently working on opt-out patches to disable that functionality
if wished. I also don't use firewalld.
It's both paternalizing and annoying and takes away user flexilibity in
exchange for nothing.
anyways
Check the nwfilter page to write own filters for the beginning:

User longer than 20 characters can't join domain (windows 7 pro)
We are using samba 3.4.8.
We have some pc's using OS Windows XP Pro dan others Windows 7 Pro.
All of them can join and logon domain to samba PDC + LDAP.
FYI, the windows 7 clients are already hacked at registry settings:

behavior of weights in nnet's multinom()
I see that "case weights" can be optioned in multinom(). I wanted to
make sure I understand what weights= is expecting. My weights (not
really mine but I'm stuck with them) are noninteger, are not scaled to
sum to the sample size, and larger weights are intended to increase
influence.
The description of various types of weights is a perennial confusion for
me; sorry.

Migrating guests
Hi,
I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands:
virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system
virsh migrate-setmaxdowntime domain 20000
However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left

Bug in KRL signature verification
I believe there has been a bug in KRL signature verification that has been
present since the KRL feature was first introduced. It prevents signed KRLs
from being loaded by OpenSSH [0]. I believe this bug applies to all
versions of OpenSSH, although the majority of my effort has been devoted to
(and all of my code snippets come from) openssl-portable.
The bug is that an offset is incorrectly

using virDomainMigrateSetMaxDowntime
I would like to use the virDomainMigrateSetMaxDowntime but I'm a bit
confused about how to use it.
If I try to set the downtime before I call domain.migrate(), I get the
error "domain is not being migrated". But I cannot call it afterwards
because domain.migrate() does not return until the migration has
completed.
Am I meant to put the call to domain.migrate() into a separate

[LLVMdev] Questions about llvm/Object/COFF.h
If you haven't already found it, you should look inside
tools/llvm-objdump/llvm-objdump.cpp, which is an easy-to-follow example of
how these APIs work

[LLVMdev] Questions about llvm/Object/COFF.h
So, I'm trying to use this file to look inside COFF files.
Got the header. OK.
Now I want to look at the sections.
Look, there's a section iterator. I can use that!
So, I write:
for (llvm::object::section_iterator iter = Obj.begin_sections (); iter != Obj.end_sections(); ++iter )
and it doesn't compile. There's no ++ for section iterators.
Apparently, you're supposed to
