[libvirt] [PATCH] Include param.h in case of HAVE_BSD_CPU_AFFINITY
by Guido Günther
This fixes compilation on kFreeBSD which otherwise fails like

from util/virprocess.c:43:

And it's the correct usage as documented in

[libvirt] [PATCH v2 0/2] Add machine type pc-1.0-qemu-kvm for live migrate compatibility with qemu-kvm
by Alex Bligh
This patch series adds inbound migrate capability from qemu-kvm version
1.0. The main ideas are those set out in Cole Robinson's patch here:
http://pkgs.fedoraproject.org/cgit/qemu.git/tree/0001-Fix-migration-from-...
however, rather than patching statically (and breaking inbound
migration on existing machine types), I have added a new machine
type (pc-1.0-qemu-kvm) without affecting any other machine types.
The existing pc-1.0 machine type is renamed to pc-1.0-qemu-git,
with pc-1.0 becoming an alias for one or another, as selected
by a configure option (defaulting to pc-1.0-qemu-git, IE no
change).
This requires 'hot patching' the VMStateDescription in a couple of
places, which in turn is less than obvious as there may be (indeed
are for i8259) derived classes. Whilst pretty nausea-inducing, this
approach has the benefit of being entirely self-contained.
I developed this on qemu 2.0 but have forward ported it (trivially)
to master. My testing has been on a VM live-migrated-to-file from
Ubuntu Precise qemu-kvm 1.0.
I have given this a moderate degree of testing but it could do
with more.
Note that certain hardware devices (including QXL) will not
migrate properly due to a fundamental difference in their internal
state between versions.
Also note that (as expected) migratino from qemu-2.x to qemu-1.0
will not work, even if the machine types are the same.
Alex Bligh (2):
Add machine type pc-1.0-qemu-kvm for live migrate compatibility with
qemu-kvm
Add configure option --enable-pc-1-0-qemu-kvm

[libvirt] [BUG] Two different connections to the same host through different transport
by Емил Гелев
Hi. I am using libvirt for some time and I have found the following problem.
When I try opening two connections with the same credentials to the same
host but using different transport(TCP and TLS) I get the following error
when trying to free the TLS one:
"*** Error in `./test': double free or corruption (!prev):

virConnectAuth auth2;
auth2.credtype = authCredTypes;
auth2.ncredtype = sizeof(authCredTypes) / sizeof(int);

virConnectPtr conn2;
conn2 = virConnectOpenAuth("qemu://host1/system", &auth2, 0);
// virConnectClose(conn); // this does not change the behaviour
virConnectClose(conn2); // here the error occurs
}
If I try to close "conn" then everything works until I try to close
"conn2". I can even invoke virConnectListAllDomains using "conn2" and use
the domain pointers when "conn" is closed. The problem is when I try to
close "conn2".
The platform running this code is Ubuntu 14.04. The version of libvirt is
1.2.2 (default configuration). The certificate of the CA which signed the
server certificate is under /etc/pki/CA/cacert.pem
The target machine is RHEL 6.5. The version of libvirt is 0.10.2. It is
configured this way:
listen_tls = 1
listen_tcp = 1
auth_tcp = sasl
auth_tls = sasl
tls_no_verify_certificate = 1
Everything else is set to default.
The certificate of the CA which signed the server certificate is under
/etc/pki/CA/cacert.pem
The user "user" is added to the DB( using $ saslpasswd2 -a libvirt user). I
can successfully execute the following on the command line using the
"user"/"pass" credentials:
virsh -c qemu://host1/system list
virsh -c qemu+tcp://host1/system list
I hope this will be useful.
Thank you.

[libvirt] virsh migrate: sometimes command line cannot exit until manually press "ENTER" key
by Chun Yan Liu
Hi, List,
Do you meet the same problem? Host is kvm, doing: (e.g.)
#virsh migrate sles11 qemu+ssh://147.2.207.55/system --live --unsafe
password:
Sometimes, VM is already running on the target host and disappears
from source host, but the command line still hangs there, if pressing
"ENTER", it will exit.
I debugged the code, but found the result is weird. The code hangs at
tools/virsh-domain.c -> cmdMigrate ->vshWatchJob->poll():
poll() is trying to select pipe_fd, which is used to receive message from
doMigrate thread. In debugging, found that doMigrate finishes and at
the end it does call safewrite() to write the retval ('0' or '1') to pipe_fd,
and the write is completed. But cmdMigrate poll() cannot get the event.
Then after pressing "ENTER" key, poll() can get the event and select
pipe_fd, then command line can exit.
Any ideas about the possible reason?
Thanks,
Chunyan

[libvirt] [PATCH 0/2] active commit fixes
by Eric Blake
In response to the valgrind trace I posted to the list last night.
Valgrind is awesome :) I had a very hard time reproducing the race
when run under gdb or at normal speeds, but valgrind was slow enough
that I was hitting it more frequently, as well as getting information
about the bug and where to go to fix it.

Thanks.
I have a question about comment style.
I see there are two comment styles in our libvirt code.
One is
/* XXXX
* XXXX
*/
The other is
/* XXXX
* XXXX */
Are both of them fine ?
Or which one is recommended ?
(I'm not sure about my comments when coding.)
