Re: [Users] too much debugging in ovirt-node

I just installed fresh server and looking at the libvirtd.conf, VDSM properly configured it to have also: log_filters=1:libvirt 3:event 3:json 1:util 1:qemu where 3:event 3:json gets rid of a lot unnecessary messages (but beware, it depends on the order in which those directives are specified). You can also have a look at what we discussed about in Bug 920614 [1], where you might find interesting settings for that as well. There is also link to the Gerrit tracker, where the issue is tracked [2] as well. Logs should also be rotated. In case there is no logrotate daemon or no rules for it, that may be another point of failure.

I was exploring the python sdk to figure out Host-VMs mapping i.e What are the VMs running on the different host. Looks like the only way to find this, is to query each VM in /api/vms list to get the host on which it is running. Is this the right way ? Is there no direct query or REST API to list the VMs running on a given host at that instant. you can run query=host = X for that. Thanks! I was able to successfully come up with the hierarchy. I was looking to get the data center hierarchy structure. Number_of_datacenters | V clusters in each data center | V Hosts in each cluster | V VMs on each host. This kind of mapping as seen on the GUI. Is there any way to obtain the same from the ovirt-python-sdk ? you can combine query to fetch vms by dc+cluster+host, query = datacenter = x and cluster = y and host = z also you can fetch hosts from the given cluster cluster=x same for cluster Datacenter.name = x With this information, this would help me write scripts to turn-off my hosts if idle automatically and power them on as required.

I wanted to know as to why start/stop of hosts options are enabled in Power Mgmt tab only when the host is in Maintenance mode and not otherwise. cause you don't want to kill all vms running on this host when switching it off, moving host to the maintenance mode will make them migrating to other host/s in the cluster, actually there are much more scenarios where you want to be sure that you can safely switch off the host. So as I understand, issuing a STOP just halts the host but not migrate VMs . This needs to be done by putting the host in the maintenance mode where all the VMs running are migrated. Host is disconnected from the storage pool after which one can shut-down the system. Maintenance is per-requisite mode where u explicitly tell the engine to migrate the VMs and disconnect host from storage and not done as part of integral shutdown process. Also, is there any way via pythonSDK to put the host in maintenance mode ?
