arjunbainduris there a way to simulate SRIOV in a virtualized env without physical Intel NICs or a physical server? I don't mean presenting VFs to Pods or VMs. This is for testing in nested virtualization environment, where our hypervisors are themselves VMs(in an Openstack or vmware cloud). Currently our VM nodes come up with virtio driver, and i'm guessing a lot more like enabling GRUB params, iommu, are needed. But is this even possible?08:00
arjunbaindurI am wondering how SRIOV is tested w/o dependency on actual physical hosts and NIC hardware08:01

ralonsoharjunbaindur, there is a emulator for developers but not useful for us08:07
ralonsohyou need to have real HW for SRIOV testing08:07
*** baojg has joined #openstack-neutron08:07
arjunbaindurWe've basically ran out of bare metal hosts, was hoping there was some way we could use VMs to emulate these for dev-test purposes08:07
ralonsohno, now is not possible to emulate SRIOV capable devices08:07

ralonsohI left those lines there just to explicitly say that I'm removing this09:01
ralonsohbecause I need to rebase the patch, I'll remove them09:01
ralonsohnow we can't test that: we don't have nested transactions in the same thread09:01

slaweqralonsoh: I just commented in https://review.opendev.org/#/c/758391/ but please tell me if I missunderstood it so I can change my vote then :)09:12
ralonsohslaweq, hehehe but this is the key point of the bug09:14
ralonsohIn case a logical switch has no name, skip the maintenance IGMP09:14
ralonsohsnoop check.09:14
slaweqralonsoh: but that will skip setting it only if MCAST_SNOOP is set AND there is no ls.name09:16
ralonsohslaweq, oh my... I'm more stupid every day!!09:16
slaweqmy understanding is that it should not check it if:09:16
ralonsohyou are right!!09:16
slawequff09:16
ralonsohthanks a lot hahahaha09:16
slaweqI though that I don't understand basic logic operations anymore :)09:17
ralonsohhahahahhaa09:17
ralonsohthanks a lot09:17
slaweq:D09:17
slaweqso maybe You can also add one more test case to cover such case when MCAST_SNOOP != value AND there is no ls.name set  - it shouldn't be set then09:18
ralonsohslaweq, yes, I need to add this test09:18

kklimonda_Hi, I'm seeing some weird connectivity issue between VM and its metadata server with ussuri ml2/ovn 20.06.2 deployment - after enough hard reboots (e.g. rescue/unrescue cycles) the VM receives IP address from dhcp server but has no communication with metadata server. Before I start digging into it, does that sound a bell to anyone?10:43
kklimonda_restarting ovn-controller fixes that10:43
kklimonda_so far the only difference I can see is one additional flow being present when communication breaks down10:45
kklimonda_haven't figured out how to diff output of `dump-flows br-int` though10:45
