Description IBM Bug Proxy 2011-04-05 19:20:35 UTC
1. Feature Overview:
Feature Id: [71035]
a. Name of Feature: [6.2 FEAT] virt-manager: Enable 'passthru' mode for direct interfaces
b. Feature Description
Support 'passthru' mode with macvlan/macvtap to enable assigning SR-IOV VFs to a KVM guest via
macvtap/virtio. In order to use this feature via virsh utility, we need to add support for
a new mode 'passthru' to the domain XML format.
    <interface type='direct'>
      <mac address='54:52:20:74:60:01'/>
      <source dev='eth10' mode='passthru'/>
      <model type='virtio'/>

Request Type: Package - Feature from IBM
d. Upstream Acceptance: Not Started

Code Contribution: IBM code
g. Component Version Target: ---

3. Business Case
This feature is required to leverage SR-IOV NICs that support multiple Virtual Functions to be
assigned to a KVM guest while supporting live migration. Direct assigment of VFs to a guest don't
allow live migration and memory overcommit.

Comment 2 RHEL Program Management 2011-04-05 19:23:45 UTC
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 3 Cole Robinson 2011-04-07 17:05:49 UTC
Blocking on libvirt support at the moment.

Comment 7 Cole Robinson 2011-06-10 22:08:55 UTC
Rather than track this separately, just merging this with the existing direct interface virt-manager request
