Re: [Openstack] [Compute] nova-compute does not show up as ":-)" in nova-manage service list

Just forget to restart nova-compute meanwhile :^)

ok I resolved the issue
libvirt misses one dependency "avahi-daemon". Here are the steps :

apt-get install avahi-daemon
service messagebus restart
service avahi-daemon start
service libvirtd restart
service nova-compute stop
nova-manage service disable $server_name nova-compute
nova-manage service enable $server_name nova-compute
nova-manage service list

Hi, I've also the same problem actually for a qemu hypervisor. I'll let you know when I come up with something. There is not any error into the nova-compute.log

So the things to check are:

 

-          Is the nova-compute service running ?  If not the nova-compute.log should show why its failing

 

-          If it is running then it probably means that its getting stuck on some long running issue (e.g as down loading an image, problems talking to libvirt, slow response from the DB, etc).     XXX in this case means that its slow in updating its services entry rather than failed as such

Shouldn't nova-network and nova-scheduler also fail then, since they share the same config file? If so, that's not what's happening with me, only the compute service is listed as "XXX".

Hi Leander,

 

The issue is the Compute is not updating its heartbeat (services table in the nova database), which is causing this.

You probably need to check database connection string in the nova.conf on the  Compute host and the db connection from the Compute host is working.

Hello,

 

 

I can't get nova-compute to show up as ":-)" under 'nova-manager service list'. I've checked the logs and can't find any error or warning. 

 

I'm using the default packages shipped with ubuntu 12.04 and have installed everything in a virtual machine.

 

Regards,

 

Leander
