Hi,

in DPDK v17.02-rc2 there is available following patch:

commit: 59317cef249c0b23098543df527b3e360ce9764f

"""
vhost: allow many vhost-user ports
Currently select() is used to monitor file descriptors for vhostuser
ports. This limits the number of ports possible to create since the
fd number is used as index in the fd_set and we have seen fds > 1023.
This patch changes select() to poll(). This way we can keep an
packed (pollfd) array for the fds, e.g. as many fds as the size of
the array.
Also see:
http://dpdk.org/ml/archives/dev/2016-April/037024.html

Signed-off-by: Jan Wickbom <jan.wickbom at ericsson.com>
Signed-off-by: Yuanhan Liu <yuanhan.liu at linux.intel.com>
"""

I tested this feature with OVS and DPDK v17.02-rc2.
I applied also this patch to DPDK v16.11 without any issues
and performed the same tests as for v17.02-rc2.
It solves the problem with connecting many VMs to one vSwitch
instance (in my tests 70 VMs) with vhost user ports.

Is it possible to backport this feature to DPDK v16.11?

It is also worth pointing out that OVS 2.7 will use 16.11 
which means we will have this bug for the next 6 months at least 
unless we can backport.

What's your opinion?

Br,
Robert

As a vhost maintainer, I think this patch could be backported to v16.11:
it resolves an issue you met.

Just let me know if anyone has objections.

> It is also worth pointing out that OVS 2.7 will use 16.11 

One question though: will they use v16.11.1 or something like that?

@Mark do you know what exactly version OVS is going to use?

We could specify what version to compile against in the documentation. OVS has a stable branch for 2.7 so we could update the documentation if we needed to use a specific tag/branch. In DPDK, does each stable release get tagged?

Yes, but the stable tree is located at

I didn't realise that this was a different repository. It sounds like we should update the documentation in OVS with this information. We could just point to the stable branch which should catch the most up-to-date bugfixes.

Thanks, Ian updated the ovs docs to reflect this. Thanks, this stable branch really helps us.

JFYI, the link address changes every time we make a release, something
like:

    http://fast.dpdk.org/rel/dpdk-16.11.1.tar.xz
    http://fast.dpdk.org/rel/dpdk-16.11.2.tar.xz
    ...

And v16.11.1 is liekly to be released next week.
