Hi All,
I have one control, one neutron and three compute nodes for deploy. Recently, I
reinstalled one of compute node's OS (Ubuntu 14.04) because a boot issue in
that machine. After Ubuntu was installed, I reconfigured exactly the same as
other two compute nodes to be three compute nodes. After it's up, I saw it's up
state from "nova service-list" in control node. In the following
nova-scheduler.log, this new installed system, compute04, has weight 1.0 and
the other two compute nodes are less than 1.0. That means the new launched
instance should be created in compute04. But, I don't see any qemu command is
applied in compute04. The dashboard instance page shows it stuck at task
"scheduling" forever after an instance is launched.
I don't see any error logs for this issue. I also installed the VM manager app
in compute04 and a VM can be created from that app. The hardware seems OK. It
seems the order to launch a VM is not passed from control node to the compute
node, compute04. How this issue can be debugged? Please advice.
Thanks,
Mitchell
