How reproducible:
100%

Steps to Reproduce:
1.Convert a rhel8.6 guest from VMware via vddk7.0.3 by v2v
# virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 esx7.0-rhel8.6-x86_64 -it vddk -io vddk-libdir=/home/vddk7.0.3 -io vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21 -ip /home/passwd
[   0.0] Opening the source -i libvirt -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 esx7.0-rhel8.6-x86_64 -it vddk  -io vddk-libdir=/home/vddk7.0.3 -io vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21
[   1.7] Creating an overlay to protect the source from being modified
[   2.5] Opening the overlay
[   7.0] Inspecting the overlay
[  48.2] Checking for sufficient free disk space in the guest
[  48.2] Estimating space required on target for each disk
[  48.2] Converting Red Hat Enterprise Linux 8.6 (Ootpa) to run on KVM
virt-v2v: error: no installed kernel packages were found.

This probably indicates that virt-v2v was unable to inspect this guest 
properly.

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]

2.Convert a rhel8.6 guest from VMware via vddk6.7 by v2v

# virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 esx7.0-rhel8.6-x86_64 -it vddk -io vddk-libdir=/home/vddk6.7 -io vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21 -ip /home/passwd

[   2.3] Opening the overlay
[   6.8] Inspecting the overlay
[  46.3] Checking for sufficient free disk space in the guest
[  46.3] Estimating space required on target for each disk
[  46.3] Converting Red Hat Enterprise Linux 8.6 (Ootpa) to run on KVM
virt-v2v: error: no installed kernel packages were found.

This probably indicates that virt-v2v was unable to inspect this guest 
properly.

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]

3.Convert a rhel8.6 guest from VMware without vddk by v2v
#  virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 esx7.0-rhel8.6-x86_64  -ip /home/passwd
[   0.0] Opening the source -i libvirt -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 esx7.0-rhel8.6-x86_64
[   2.7] Creating an overlay to protect the source from being modified
[   3.7] Opening the overlay
[  35.3] Inspecting the overlay
[ 298.1] Checking for sufficient free disk space in the guest

[ 298.1] Converting Red Hat Enterprise Linux 8.6 (Ootpa) to run on KVM
virt-v2v: error: no installed kernel packages were found.

properly.

  virt-v2v -v -x [...]


Actual results:
As above description

Expected results:
Virt-v2v can convert rhel8.6 guest from VMware on rhel8.7

Comment 5 Richard W.M. Jones 2022-05-24 08:05:45 UTC 
I agree.  Let's continue looking at this in bug 2089623, since
the two bugs are basically the same thing.
