RDMA-based Migration of Live Guests
by Gianluca Cecchi
Hello,
I see a title as in subject on RH EL 7.1 release notes (and I presume the
same functionality to be inside the just released, right now in
respin/remirror, CentOS 7.1).
Description says:
The support for Remote Direct Memory Access (RDMA)-based migration has been
added to
libvirt. As a result, it is now possible to use the new rdma:// migration
URI to request migration
over RDMA, which allows for significantly shorter live migration of large
guests. Note that prior to
using RDMA-based migration, RDMA has to be configured and libvirt has to be
set up to use it.
What about enabling into oVirt too, via os support detection or something
similar?
Eventually in 3.6 and not in 3.5 trunk.
I didn't delve yet with it and its configuration, but I think it could be a
nice thing for oVirt.

Get involved in oVirt project! Spring Holidays / April edition
by Sandro Bonazzola
Hi,
have you got some free time in upcoming holidays and do you want to get involved in oVirt project?
Do you like the idea of having fresh disk images of recent distribution in oVirt Gluster repository?
You can help us by testing existing online images (like https://getfedora.org/en/cloud/download/) ensuring they works with cloud-init
or creating one yourself and report your success to devel(a)ovirt.org.
We'll be happy to upload the images once these are ready.
Do you like Debian and do you have some programming skill?
Help us getting VDSM running on it!
You can follow the progress here: http://www.ovirt.org/VDSM_on_Debian

Guest PXE boot with 2 NICs : MAC order
by Nicolas Ecarnot
Hello,
I can't remember if I already asked that here, but my researches
returned nothing obvious.
It is frequent in our setup to boot a VM setup with two NICS :
- one in a network with a DHCP server, leading to a PXE/tftp/kickstart setup
- a second one with a network with no DHCP, nor routed. We use this
network in some cases to access iSCSI data.
When PXE booting such a VM, I realized that in gPXE, the NICs are order
according to their MAC address (net0, net1...)
I found no mean to explicitly tell gPXE to use a specific interface, and
it is a pain, because my setup workflow implies I could choose the
correct interface.
In the oVirt web GUI, I found nothing about that.
In the ovirt-shell, I had no better luck.
In the gPXE wiki, I found nothing more that what's above.
This is not a big issue, but was worth asking.

VDSM memory consumption
by Federico Alberto Sayd
Hello:
I am experiencing troubles with VDSM memory consuption.
I am running
Engine: ovirt 3.5.1
Nodes:
Centos 6.6
VDSM 4.16.10-8
Libvirt: libvirt-0.10.2-46
Kernel: 2.6.32
When the host boots, memory consuption is normal, but after 2 or 3 days
running, VDSM memory consuption grows and it consumes more memory that
all vm's running in the host. If I restart the vdsm service, memory
consuption normalizes, but then it start growing again.
I have seen some BZ about vdsm and supervdsm about memory leaks, but I
don't know if VDSM 4.6.10.8 is still affected by a related bug.
Any help? If you need, I can provide more information
Thank you
