Enable KSM for KubeVirt #192
Conversation
The Kernel Samepage Merging should help in reducing the memory footprint for the test. See: https://kubevirt.io/user-guide/cluster_admin/ksm/ Signed-off-by: Alice Frosi <afrosi@redhat.com>

When the CI is more stable, we could try to run some of the tests in parallel and the KSM can help in reducing the memory consumption |

No I haven't, but it merges and shares several pages. So, it should help decreasing the memory footprint. I can try to come up with the memory saving on the next run of the tests |

With the page sharing and letting running 4 VMs in parallel with 4GB memory for 2 min, we save around 2172 MB. I calculated with this command |
