Why are you doing any of this?  Try it without any of that.

Also (if it still fails) please collect the full output using virt-resize -v -x and
attach that to the bug.

Comment 6 Keigo Noha 2019-08-22 00:26:19 UTC

Hi Richard,

I ran the command without the env parameter on RHEL7 works for RHEL7 images.
However, for RHEL8 image, virt-resize doesn't work fine.
I found the solution about the issue with RHEL8 image.

https://access.redhat.com/solutions/4073061

I understand the use case is not supported. So, I close this bugzilla as WONTFIX.

Thank you,
Keigo Noha
