1161575 – Failed to import guest with "rtl8139" nic to openstack server after converted by v2v

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Steps to Reproduce:
1. Prepare a guest with "rtl8139" nic.
# virsh dumpxml win2k8r2 
...
    <interface type='network'>
      <mac address='52:54:00:be:b9:46'/>
      <source network='default'/>
      <model type='rtl8139'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>
...

2. Use virt-v2v convert this guest to openstack server:

3. Login openstack server and try to import.

Actual results:
Import guest image file failed:
File "/usr/lib/python2.7/site-packages/nova/scheduler/filter_scheduler.py", line 108, in schedule_run_instance raise exception.NoValidHost(reason="") 

Expected results:
Import guest successfully.

Additional info:
1. Will attach nova-scheduler.log.

Comment 2 Richard W.M. Jones 2014-11-07 11:21:46 UTC

Hey Dan:

Do you know if we are disabling the rtl8139 driver in RHOS?

Comment 3 Richard W.M. Jones 2014-11-07 11:23:15 UTC

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.

Comment 4 Richard W.M. Jones 2014-11-07 11:24:11 UTC

Urrggh, I'm stupid.  Spot the deliberate error:

| Property 'hw_disk_bus'     | rtl8139                              |
| Property 'hw_vif_model'    | ide                                  |

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

2. Launch images on openstack server and instance can boot up successfully.
