Comment 13 for bug 1651678

Looks like the instance booting block on acquire lock on COMPUTE_RESOURCE_SEMAPHORE?

The instance stop after:

Then periodic task update_available_resource always get the lock:

release the lock http://logs.openstack.org/39/404239/14/check/gate-tempest-dsvm-ironic-ipa-wholedisk-pxe_snmp-tinyipa-ubuntu-xenial-nv/8f98498/logs/screen-n-cpu.txt.gz#_2016-12-21_13_24_24_367

Then acquire lock soon http://logs.openstack.org/39/404239/14/check/gate-tempest-dsvm-ironic-ipa-wholedisk-pxe_snmp-tinyipa-ubuntu-xenial-nv/8f98498/logs/screen-n-cpu.txt.gz#_2016-12-21_13_24_24_370

I don't know why update_available_resource always run, there should be 60 seconds interval?
