-net user is not supported. Does this work with -net tap?
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion.
I can not reproduce this under -net tap, looks like the problem of -net user.
Since -net user isn't supported, I'll mark this as NOTABUG.
