Can not reproduce on rhel6.9 with manual test. Installed latest rhel6.9 host and guest and ran the supplied test. eth0.3164 was created successfully. Can you please re-test. Thanks vlad
QE re-tested with following versions: Host: 2.6.32-672.el6.x86_64 qemu-kvm-0.12.1.2-2.496.el6.x86_64 Guest: 2.6.32-671.el6.x86_64 create 4000 vlan also no this issue, seems this is a auto bug.

I don't think so. I found the issue with autotest, but i can reproduce it manually when i filed this issue
