Extended DPDK support in oVirt[0]
by Leon Goldberg 31 Jul '18

31 Jul '18

Hi, oVirt support for DPDK was introduced in 2017[1], and is now enhanced in terms of deployment via Ansible[2] and usage via OVN. Compatible hosts and NICs can now be easily configured to use userspace drivers, while usage is enhanced via OVN, allowing for both increased performance and SDN usability. For additional information and instructions, please refer to this blog post[0].

oVirt Dashboard issues
by Hetz Ben Hamo 31 Jul '18

31 Jul '18

Hi, Whats up with the oVirt Dashboard? it has few problems:. You can see my Dashboard here: https://imgur.com/a/n4IWppe * the errors/warning cube doesn't update so much even after cleaning and waiting an hour or 2 * Cluster cube shows "1 cluster" but also "N/A" even when my cluster is up with 2 machines (with DNS names). * The memory calculation is wrong - it still shows 503.5 GB even if 1 node is down for maintenance (which means I need to see something like 220GB) Should I open bugs on all of them in 1 bugzilla? if so, on which product? Thanks, Hetz

Image Transfer mechanism queries/API support
by Ranjit DSouza 31 Jul '18

31 Jul '18

Hello oVirt Development team We had a conversation with Pavan Chavva for supporting RHV. He had suggested to contact you with queries related to oVirt APIs we plan to use. We have following queries: 1. While downloading a snapshot disk, can we identify allocated extents and download only those using oVirt API? We are able to download the disk using the Image Transfer API mechanism. However, this method downloads the entire disk including the non-allocated extents, which is a performance overhead. If this functionality does not exist at this point will it be available in near future? 2. Is there an alternate method to transfer a snapshot to and from RHV storage? Are there other methods such as NFS share where we can download snapshot image to and from RHV storage? Thanks Ranjit Team EverestFalcons
