Hi,

I reran the test on: https://gerrit.ovirt.org/#/c/92734/

3 tests passed and two failed on:

004_basic_sanity.vm_run

The error is:

detail: Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host lago-he-basic-ansible-suite-master-host-0 did not satisfy internal filter Memory because its available memory is too low (656 MB) to run the VM.

It looks like there is not enough memory on the test environment and that may be causing intermittent errors on the other tests as well.

Is it possible to increase the memory for the CI environment so that we can ensure the errors are not due to lack of resources?

With Best Regards.

Steven Rosenberg.

Hi,

The jenkins job is no longer available, I will run the test manually and see why it fails.

Maybe this patch will fix the problem with the test: https://gerrit.ovirt.org/#/c/92734/

It ensures that all services are stopped before starting them again.

The purpose of the test is to try restarting the HE VM.

When the HE VM is run for the first time, the engine generates an OVF file describing the HE VM. Then when the VM is started again, the OVF is used. We wanted to test that the generated OVF is correct and the VM can be started.  The test intended to cleanly shutdown and restart the vdsm.

vdsm then stays for the 10 minutes above mentioned waiting for the storage pool to go up:

Andrej, I see the test has been added by you in commit e8d32f7375f2033b73544f47c1e1ca67abe8d35a

I'm not sure about the purpose of this test but I don't understand why we are restarting the services on the host.

Nir, Tal, any idea on why the storage pool is not getting up?

I see vdsm is in recovery mode, I'm not sure if this was what the test was supposed to do or if the intention was to cleanly shutdown vdsm and cleanly restart it.
