RDMA-based Migration of Live Guests
by Gianluca Cecchi 01 Apr '15

01 Apr '15

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. Gianluca

Guest PXE boot with 2 NICs : MAC order
by Nicolas Ecarnot 01 Apr '15

01 Apr '15

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. -- Nicolas Ecarnot

VDSM memory consumption
by Federico Alberto Sayd 01 Apr '15

01 Apr '15

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
