Hi All,
I'm implementing VM migration support for open-VPP, an open source Vector
Packet Processing (VPP) technology (https://wiki.fd.io/view/VPP) - A Linux
foundation project. In lieu of it, I have hit an issue and I need some
clarification.
In Qemu's vhost-user implementation, each queue is

Solution:
--
VHOST_USER_RESET_OWNER API is issued by QEMU so that DPDK slave
application is informed that mappings will be soon gone so that
it can take necessary steps.

If a guest has vhost-user enabled, then on reboot vhost_virtqueue_stop is
invoked. This unmaps vring memory. However, it will not give any indication
to the underlying DPDK application about it. Therefore, a pollmode DPDK
driver tries to read the ring to check for packets and segfaults.

Hi,
I'm profiling memcpy and seeing strange behavior (for me at least) and
wanted to see if some one has an idea what may be happening.
My set up is as follows:
I have a Ubuntu 12.04 Linux host running 3.2.0-23 kernel. It has a four
10-core dual-hyper-threaded CPU with 128GB RAM. I have
Hi All,
I'm using the following command to have two nics in multicast on the
same vlan. I see a storm of ARP requests. Does any one have any
suggestions?
qemu.bin.kvm84 -hda /live_disks/clone-disk.img -snapshot -serial
telnet:SERVER:5,nowait,server -monitor
