FL1SKHi guys16:16
FL1SKWas there anything done on the Security side with HDFS and Sahara integration in Mitaka16:17
*** david-lyle has quit IRC16:24
vponomaryovFL1SK: HDFS driver in manila is kind of orphaned. no one updates it - https://github.com/openstack/manila/commits/master/manila/share/drivers/hdfs/hdfs_native.py16:26
vponomaryovFL1SK: then, this driver has nothing to do with Sahara16:26
FL1SKreally16:27
FL1SKWow16:27
vponomaryovFL1SK: why wow?16:27
vponomaryovFL1SK: it works with filesystem, not OpenStack service16:27
FL1SK:-)16:27
FL1SKoh gotcha vponomaryov16:28

*** harlowja has joined #openstack-manila20:36
gouthamrbswartz: we;re in this room for the working session at 5:20.. will we have that streamed/recorded?20:37
bswartzwinston-d winston-d_: http://vmsplice.net/~stefan/stefanha-connectathon-2016.pdf if you look at slide 15, the NFS utils patch is the only missing one20:37
bswartzyou don't need vsock support in nfs-kernel-server because you can use ganesha20:38
bswartzgouthamr: streamed: yes, recorded: no20:38
winston-d_bswartz: yes, ganesha can do whatever k-nfsd should do, and it's ready.20:39
bswartzwinston-d_: https://github.com/stefanha/nfs-utils <-- looks like waiting for vsock support in glibc20:40
*** cknight has joined #openstack-manila20:43
winston-d_bswartz: a lot things that are needed to get the whole vsock stuff working for FS host-mount: 1) add virtio transport for AF_VSOCK into linux kernel: http://www.spinics.net/lists/kvm/msg130190.html, the latest version patch was up 1st. April, targeting v4.5; 2) add virtio-vsock support to qemu: https://github.com/stefanha/qemu/tree/vsock; 3) libvirt support20:51
winston-d_for vsock device, no patch found; 4) nfs-utils vsock support.20:51
*** lpetrut has joined #openstack-manila20:52
*** bill_az_ has quit IRC20:54
*** lpetrut has quit IRC20:56
bswartzwinston-d_: what makes you think that any changes to libvirt are needed at all?21:04
bswartzwhen I think about vsock connection from hypervisor to guest VM it seems that libvirt doesn't need to be involved21:05
winston-d_vsock is a new device in qemu, libvirt has to support that to be useful in OpenStack environment.21:05
winston-d_A vsock device has to be added to VM to open this hypervisor to VM channel21:06
winston-d_Or maybe I missed some magic and can automatically done for VM21:07
*** harlowja has quit IRC21:10
*** cknight1 has joined #openstack-manila21:10
gregsfortytwoI don't know for certain, but the whole point of vsock is to be zero-config21:11
gregsfortytwoso I don't think libvirt will need to plumb anything together the way it would for looping back a tcp/ip network connection21:11
gregsfortytwoalthough the host might need something to accept stuff21:12
*** cknight has quit IRC21:12
*** xiaoxi has joined #openstack-manila21:13
*** gouthamr has quit IRC21:14
winston-d_zero config in terms of? my understanding is zero config could simply refer to 'user don't have to do anything to make the vsock device to able to talk to host' that kind of 0-config21:14
*** mtanino has quit IRC21:14
winston-d_but i can be quite possibly wrong21:14
bswartzwinston-d_: I imagine that ganesha just binds to vsock:0 on the hypervisor and the kernel does the rest21:14
*** breitz has quit IRC21:15
winston-d_bswartz: yeah, mostly, but VM kernel has to load a vsock device driver, and before that a device should be added to VM somehow.21:15
gregsfortytwohmm, I'm not sure at that level of detail -- I thought you just had to register a vsock listener and they would get all guest connections, but I could be spewing nonsense21:15
*** david-lyle has quit IRC21:17
*** gouthamr has joined #openstack-manila21:22
winston-d_Stefan's wiki: http://qemu-project.org/Features/VirtioVsock21:23
winston-d_indeed he didn't mention adding device to VM, so I guess I was wrong about the libvirt part.21:24
*** cknight1 has quit IRC21:24
*** bill_az has joined #openstack-manila21:25
*** cknight has joined #openstack-manila21:32
bswartzwinston-d_: yeah that's one of the really attractive aspects of nfs-over-vsock21:33
bswartznot depending on libvirt at all is a big win IMO21:33
winston-d_to us, working around networking issue is the big win, the orchestration part in Nova is trivial and solvable problem 'cos host-mount itself already means a lot of work has to be done in Nova to make it work.21:36
winston-d_but of course, less dependency is always better21:38
