Description Huang Wenlong 2011-02-14 09:19:48 UTC 
Description of problem:
convert rhel4u8 guest from esx to kvm (libvirt and rhevm) modprobe.conf is incorrect 
the network and storage driver are not virtio 

Version-Release number of selected component (if applicable):
virt-v2v-0.6.3-5.el5

libguestfs-1.2.7-1.el5.8

libguestfs-*-1.2.7-1.el5.8

libvirt-0.8.2-15.el5_6.1

febootstrap-2.6-1.el5.2

hivex-1.2.2-1.el5.1

augeas-libs-0.7.3-1.el5.1

virtio-win-1.0.1-2.52454.el5

RHEVM ic91

rhevh-5.6-8.1

How reproducible:
always

Steps to Reproduce:
1.# virt-v2v -ic esx://10.66.72.149/?no_verify=1 -op esx -n default ESX4.0-rhel4u8-32b

unknown filesystem /dev/hdc
unknown filesystem /dev/fd0
virt-v2v: No capability in config matches os='linux' name='virtio' distro='redhat-based'
virt-v2v: ESX4.0-rhel4u8-32b configured without virtio drivers

2.check the modprobe.conf
# cat /etc/modprobe.conf 
alias eth0 e1000 

  
Actual results:
alias eth0 e1000 


Expected results:
alias eth0 virtio
  

Additional info:
esx3.5 esx4.0 and esx4.1 all can reproduce this bug 
/boot/devive.map is not update  
if the guest is rhel4u9 ,everything is fine .

sorry Matt , We install the wrong guest(redhat desktop 4u8 ) ,the "Red Hat Enterprise Linux 4u8" is fine ,but it is also a bug .
Comment 3 Matthew Booth 2011-02-14 11:12:09 UTC 
Note from the error message that the guest OS has been detected as 'redhat-based', which we don't have any config for:

virt-v2v: No capability in config matches os='linux' name='virtio'
distro='redhat-based'

This seems to be an oversight in libguestfs's OS detection. I've moved this to to libguestfs and updated the title.
Comment 4 Richard W.M. Jones 2011-03-07 13:01:07 UTC 
Huang, could you please let us know the contents of the file:

  /etc/redhat-release

from *inside* the guest?
Comment 5 yuping zhang 2011-03-08 03:07:13 UTC 
From guest:
#cat /etc/redhat-release
Red Hat Desktop release 4 (Nahant Update 8)
Comment 6 Richard W.M. Jones 2011-03-08 07:54:19 UTC 
I see the problem.  Cloning this bug for upstream and 6.2.
Comment 7 Richard W.M. Jones 2011-06-13 21:08:23 UTC 
Damn I'd forgotten about this bug (or rather, have plans
to fix it in 6.2).  We're too late for 5.7 obviously, and
unless we rebase libguestfs and virt-v2v in 5.x (not likely)
we can't fix it very easily.

Since this hasn't been reported by a customer and we are
going to fix it in RHEL 6, I'm closing this.

Please reopen if there is a reason to fix this in RHEL 5,
but be aware that a fix could be disruptive.
