We should not use nested kvm > for the CI, such vms are much slower then regular vms, and we probably run > too many vms per cpu. > We can disable such tests in the CI, but we do want to know when there is > a regression in this code. Before it was fixed, the same test took 9 seconds > on my laptop. We need fast machines in the CI for this. > Nir -- This message was sent by Atlassian JIRA (v1000.620.0#100023) _______________________________________________ Infra mailing list Infra@ovirt.org http://lists.ovirt.org/mailman/listinfo/infra
