Bug 1176598

What does the data domain look like in that case?  I looked at
one on my machine and it used <domain-id>/master/vms/<vmid>.

it maybe an old domain, I think the new format not longer have the vms (it does have an empty vm directory for backward compatibility).

Posted patch to:
https://www.redhat.com/archives/libguestfs/2014-December/msg00183.html

This has been committed upstream as 14d11916faf68afb672d1626348931f2b90afd08.

Try to verify this bug on new build:

libguestfs-1.28.1-1.33.el7.x86_64
libvirt-1.2.15-2.el7.x86_64
virt-v2v-1.28.1-1.33.el7.x86_64

Steps:
1. Check whether option "--vdsm-ovf-output" has added:
1.1 Check virt-v2 manual page:
# man virt-v2v
...

       --vdsm-ovf-output
...

           ·   the OVF output directory (default current directory) (--vdsm-ovf-output).

1.2 Check virt-v2v help info

# virt-v2v  --help
  --vdsm-ovf-output                           Output OVF file

Result: New option has added.

2. Use virt-v2v convert a kvm guest to rhev.

2.1 Check rhev Data Center path and mount it to local:
(I mount nfs path to local since bug 1176591, i'm not sure whether my steps is right or not, please also help me check, thanks)

Path: 10.66.90.115:/vol/v2v_auto/nfs_export
# mount 10.66.90.115:/vol/v2v_auto /mnt

2.2 Create 2 new path:
images/12345678-1234-1234-1234-123456789001
master/vms/12345678-1234-1234-1234-123456789003

2.3 Run virt-v2v command:
# virt-v2v  -o vdsm -of raw --vdsm-image-uuid 12345678-1234-1234-1234-123456789001  --vdsm-vol-uuid 12345678-1234-1234-1234-123456789002 --vdsm-vm-uuid 12345678-1234-1234-1234-123456789003 --vdsm-ovf-output /mnt/nfs_export/8a94984a-a1e2-465d-83e7-a2f8165aaffe/master/vms/12345678-1234-1234-1234-123456789003 -os /mnt/nfs_export/8a94984a-a1e2-465d-83e7-a2f8165aaffe   rhel6.6-juzhou-smartcard

2.4 Login rhevm and try to import images.

Result: Failed to import for error:
Cannot import VM. VM'S Image does not exist.
I will attach engine.log.

So rjones, please help me have a look, thanks.

Your verification is correct, up to this point:

> 2.4 Login rhevm and try to import images.
> 
> Result: Failed to import for error:
> Cannot import VM. VM'S Image does not exist.
> I will attach engine.log.

Normally end users would use '-o rhev' to import and image, which appears
in RHEV's Export Storage Domain (ESD).  However this bug is about '-o vdsm'
which is a private mode used by VDSM to import directly into the RHEV
Data Domain (not going via ESD).

When VDSM uses '-o vdsm' it also does some updates to RHEV's database so
the imported image just appears.

It's not possible for us to emulate those database updates.  Without them
the imported VM is not visible anywhere.

So your verification is correct, as far as it is possible for us to test
it, and I think you can mark the bug as VERIFIED.

Hi rjones,
