Hey Dan: Do you know if we are disabling the rtl8139 driver in RHOS? I should note that when Junquin looked into one of the Nova log files, she found: u"UnsupportedHardware: Requested hardware 'rtl8139' is not supported by the 'kvm' virt driver\n" which is the reason we think the NIC specifically is to blame here. Urrggh, I'm stupid. Spot the deliberate error: | Property 'hw_disk_bus' | rtl8139 | | Property 'hw_vif_model' | ide | Upstream fix: https://github.com/libguestfs/libguestfs/commit/7407c0ae14c382e11e93afe94c0fc37d16df6ae9 (In reply to Richard W.M. Jones from comment #2) > Hey Dan: > > Do you know if we are disabling the rtl8139 driver in RHOS? I'll let Dan reply, but I saw this from RHOS (and upstream) Nova code: commit 40f3724bec5cc9883af7597af6c33c480b7d3c97 Author: Daniel P. Berrange <berrange> Date: Mon Dec 17 15:04:18 2012 +0000 Make libvirt driver default to virtio for KVM/QEMU NICs Currently users of KVM/QEMU must set libvirt_use_virtio_for_bridges to true to get a virtio based NIC, instead of the awful rtl8139 that QEMU defaults to. Switch libvirt_use_virtio_for_bridges to default to enabled, but ensure it only takes effect if libvirt_type is 'kvm' or 'qemu'. Although it is possible that some guest OS do not support virtio drivers, currently Nova hardcodes use of 'virtio' for disks, so this change doesn't make the current guest OS support situation worse. Obviously in the future, both NIC & disk models will have to be made fully configurable Change-Id: I7c0d306921f554ac2d06b5bdb1f9017ab7f9c643 Signed-off-by: Daniel P. Berrange <berrange> Try to verify this bug with new build:
steps:
1. Convert a guest with no virtio driver installed on it:
# virt-v2v -i disk /var/lib/libvirt/images/win2k8r2.qcow2 -o glance
[ 0.0] Opening the source -i disk /var/lib/libvirt/images/win2k8r2.qcow2
[ 0.0] Creating an overlay to protect the source from being modified
[ 0.0] Opening the overlay
[ 67.0] Initializing the target -o glance
[ 67.0] Inspecting the overlay
[ 69.0] Checking for sufficient free disk space in the guest

virt-v2v: warning: there are no virtio drivers available for this version

/usr/share/virtio-win
The guest will be configured to use slower emulated devices.

[ 353.0] Finishing off
Result: conversion finished successfully.
and this part showing is right now:
| Property 'hw_disk_bus' | ide |
| Property 'hw_vif_model' | rtl8139 |
2. Launch images on openstack server and instance can boot up successfully.
3. Always test with win7 guest, can pass also.
See above steps, move this bug from ON_QA to VERIFIED.
