Saksham Srivastava commented on CLOUDSTACK-7186:
------------------------------------------------
The issue is happening because of failure during comparison of mac address of
vpc router in nics table and the mac address of the router on the hypervisor.
In a Xenserver setup, CitrixResourceBase.java:
prepareNetworkElementCommand(SetNetworkACLCommand cmd)
NicTO nic = cmd.getNic();
VIF vif = getVifByMac(conn, router, nic.getMac());
//vif turns out to be null.
Similarly in
prepareNetworkElementCommand(SetupGuestNetworkCommand cmd)
String mac = nic.getMac();
VIF domrVif = null;
for (VIF vif : vm.getVIFs(conn)) {
String lmac = vif.getMAC(conn);
if (lmac.equals(mac)) {
domrVif = vif;
break;
}
}
if (domrVif == null) {
return new ExecutionResult(false, "Can not find vif with mac "
+ mac + " for VM " + domrName);
}
lmac and mac do not match and null value is returned and hence the NPE.
