The issue arises because firewall depends on qemu-server but qemu-server
depends on SDN. So if I try to include firewall from SDN, it will not work.
I have looked at Firewall for quite some time now. Some functions in
Firewall.pm depend on QemuServer mainly for the parse_net function. I
tried to extract the functions that depend on QemuServer to another
package but I couldn't get the tests to pass.
Firewall.pm is using several global variables and I couldn't identify
what I missed.
Another option would be to split the SDN module to allow QemuServer to
depend only on a certain part of SDN to notify SDN about nic added to a
VM and VM start. I have not analyzed if it's possible to can split the
I don't see a clear path to implement this at this point and I will
focus on supporting Stefan Hanreich next week to finalize other aspects
of SDN for a successful release.
