Public bug reported:
When creating a multiple in the row KVM instances with an SR-IOV interface this
way:
manually
- openstack port create --vnic-type direct --network sriov-net sriov-portN
(2 sec pause)
- openstack server create --port sriov-portN --image bionic-sriov
--availability-zone nova:hostname --flavor m1.small --key-name maaskey
test-sriovN
(2 sec pause)
and x 5 times.
The host hangs, stops being accessible via juju ssh, ssh attempt to bondm
address gets connection refused.
Icmp to host gets response though.
If I type password manually in ilo console - there is no bash prompt after it.
After rebooting I found the following in journalctl :
