Bug 465587

Created attachment 319442 [details]
virt-p2v.log

Description of problem:
virt-p2v doesn't understand linux software raid.

Version-Release number of selected component (if applicable):
virt-p2v-0.9.7.iso 

How reproducible:
Always.

Steps to Reproduce:
1. Install Linux (my case, RHEL4) on a physical multi-drive (my case, 3 SCSI drives) system.
2. Create a Software RAID1 (This contained my /boot) and a Software RAID5 (This contained my single LVM Physical Volume) that spans the disks (I would assume this fails equally for RAID0, but did not test that).
3. Use virt-p2v LiveCD to transfer the image over to a Fully Virt Xen Host (in my case, RHEL5).
  
Actual results:
Failure due to not detecting that the partitions are software RAID, and instead is trying to read the partitions as Logical Volumes or some other formatted partition.

Expected results:
Should be able to detect the software raid and construct the disks in the virtual guest image.

Hello,

I was in the process of moving a server using virt-p2v this evening,
when I came across the issue described at:

https://www.redhat.com/archives/et-mgmt-tools/2008-February/msg00037.html
https://www.redhat.com/archives/et-mgmt-tools/2008-February/msg00038.html

https://www.redhat.com/archives/et-mgmt-tools/2008-February/msg00040.html

I was wondering if there is any progress on getting linux software raid
support.  I'm not really qualified to help with patches, but I'd be more
than happy to test any patches to get this functionality in.  It appears
I have a similar setup where I have three physical drives, three
identical partitions in a software RAID-1 (/boot), three identical
partitions for swap, and three identical partitions in a software RAID-5
(/).  And of course it bails out because it doesn't understand the
software raid type.  If there is a bug, or anything I can do to help on
this front, please let me know, as this has thrown a bit of a
monkey-wrench into a migration plan that I had, but could not test until
now.

Thanks!
Brandon

Sorry I wasn't concentrating very hard on this list for the past
couple of weeks.

virt-p2v doesn't understand RAID devices at all.  There's no real
limitation here, it's just that you're the first person who has asked
about it.

Can you open a bug report, and also send the virt-p2v.log file from
your attempted installation.
