Hi,
I reproduced your set-up but did not get the same result. I can see 8 queue
pairs (8 x rx and 8 x tx) on the guest for each vHost device. Like you said
perhaps somebody else on t
Hi,
Since the segmentation fault is occurring in the DPDK vhost code, it might be a
good idea to post this information to the d...@dpdk.org mailing list where you
might be able to get more feedback on the root cause.
Thanks,

Hi Patrik,
The majority of your concerns seem to be to do with the DPDK code itself so I
would suggest posting to the d...@dpdk.org mailing list to raise your concerns,
especially questions 2 & 3. Either way some comments/questions below.

The latest one should do. R1.1. There should be a qemu directory inside this
tarball. Compile this, and use it when running the IVSHM test with dpdkr ports.

HMEM configuration.
What is your intention? Do you wish to use IVSHM to communicate with a VM? If
so I recommend you refer to the steps in INSTALL.DPDK explaining 'DPDK Rings' /
'dpdkr' ports.

At the moment multiqueue support is not available in OVS for vHost.
