Change default libvirt storage pool location on KVM
When I add a new KVM host to a cluster it sets up a default Primary storage that's pointing to the /var/lib/libvirt/images/ directory on the KVM host. I've dug around trying to find where to change that default but I'm not see where it's being configured.
I've tried to change the local_path values in the storage_pool and storage_pool_host_ref tables, but I keep getting errors when trying to spin up the systemvms.
Is this something that is configured through cloudstack somewhere or something I need to change in libvirt when configuring a new KVM host and where/how would I change that? The libvirt docs show some XML files that describe how that's setup and that /var/lib/libvirt/images/ is the default, but doesn't explain where/how to change that.
Thanks,
Travis

Until you figure this out, you can use bind mount to bind
/var/lib/libvirt/images to a larger local directory. Lines such as this
would exist in /etc/fstab;
/data1/var/lib/libvirt/images /var/lib/libvirt/images none bind 0 0
ignore if you are already using this method and need to other method to
meet your requirements.

Fair enough. I am running 4.0.1, so it must have been removed then. I would restart the agent though to be safe. Might be worth asking on the dev list as well since I would imagine someone there knows what the agent does to get its local storage path. Let me know if you find out what the new approach is as I expect to be setting up a KVM cluster with 4.2 in the next couple months (which will hopefully be the same). =D

The path in the table is set to /var/lib/libvirt/images/ and as I mentioned earlier, I tried to change it in the db with no luck. Not sure if I should have restarted cloudstack-agent or not to pick up any settings changed in the db.

Hello Dave,
I don't have a local.storage.path variable in my agent.properties file, instead I have local.storage.uuid which is set to the uuid in the storage_pool table. The path in the table is set to /var/lib/libvirt/images/ and as I mentioned earlier, I tried to change it in the db with no luck. Not sure if I should have restarted cloudstack-agent or not to pick up any settings changed in the db.
I'm using the 4.1.1 agent so I'm not sure if that property was removed since the 4.1.0 release.
Thoughts?

Travis,
Change the property local.storage.path in /etc/cloud/agent/agent.properties.
Thanks, Dave

Hello Travis,
If you are using virt-manager GUI then you can select the host, in case of
localhost select localhost (qemu connection) go to edit->connection details
there you have storage and you should be able to delete add or whatever.
If no GUI then use 'virsh' with storage pool commands.
first 'virsh pool-list, then virsh pool-destroy and finally virsh
pool-define with your xml config I believe.
Thanks,
Jithin
