Description Rik van Riel 2006-09-12 11:13:53 EDT
Description of problem:

When converting a RHEL4 fully virtualized guest to a paravirtualized guest,
Kudzu will happily offer you to throw away the configuration for all the (no
longer present) "physical" devices, but it will not set up configuration for the
virtual devices at all.

This leads to a virtual machine without a network.

Steps to Reproduce:
1. install RHEL4 fully virt guest
2. install paravirt kernel in that guest
3. twiddle /etc/xen/guest config file to boot it paravirt
4. kudzu offers to remove all device configuration on bootup
5. do as kudzu suggests
6. network device is gone
  
Expected results:

Kudzu should configure Xen virtual devices.

Needs done for 4.5, yes?
Comment 2 Rik van Riel 2006-09-12 11:35:50 EDT
Yes. Can't set those flags from the initial bug creation though :)
Comment 3 RHEL Product and Program Management 2006-09-12 11:46:55 EDT
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
Comment 5 Jeremy Katz 2006-10-18 16:05:56 EDT
More importantly, this is needed so that anaconda can find the devices so we can
get the right install experience :-)

And committed bits for that, will be in 1.1.95.16
