<P>hi, i run command nova evacuate failed, anyone can help point out
direction?<BR>steps:<BR>1.run two compute host A and B<BR>2.run instance vm01 on
host A, shutdown host A<BR>3.run command nova evacuate --on-shared-storage vm01
B</P>
<P> </P>
<P>------------------------------------------------------------</P>
<P>My analysis is:</P>
<P>When VM starting to be created in Host B, I can see the
'network-vif-plugged' message showed up in neutron server log.</P>
<P>but after VM is created, no more neutron 'network-vif-plugged' rpc
message generated, thus we got 'timeout' error.<BR>actually no any error
messages in neutron server log during evacuation.<BR></P>
<P>i see from source code that it has some notifier with port api
create/<WBR>delete/<WBR>update and port db insert/update/set.<BR>i guess
that it is due to the port data not changed during evacuation, so no
any message to be sent out as notification</P>
<P> </P>
<P>could any confirm this?</P>
<P> </P>
