Version-Release number of selected component (if applicable):
virt-install.noarch     2.0.0-5.el8                            @beaker-AppStream


How reproducible: Always (with this image)

Steps to Reproduce:
Fresh install of RHEL-8.0.0-20190325.n.0

One attempt to virt-install with --import (not sure if it matters)

Comment 1 Cole Robinson 2019-03-26 16:03:45 UTC 
We narrowed this down after a debugging session. What happened was:

* The first virt-install invocation used --disk /var/lib/libvirt/images/some-preexisting-path.qcow2
* virt-install imports the parent directory /var/lib/libvirt/images as a pool, names it 'images' after the last directory bit
* next virt-install run uses --disk size=X
* virt-install tries to look up pool name=default. there is no pool named default
* next it tries to lookup a pool using the default path /var/lib/libvirt/images, finds pool name=images
* however it fails to return name=images up to caller, which then tries to blindly look up name=default, which throws the erro

This is fixed upstream now with:

    cli: Fix pool=default when path belongs to another pool (bz 1692489)
Comment 6 zhoujunqin 2019-07-08 07:25:18 UTC 
I can reproduce this bug with build:
virt-manager-2.0.0-5.el8.noarch

Steps:
1. Remove default storage pool if it exists.

2. Define new storage pool that will point to the same directory as the default one with a different name then 'default:

# cat pool-images.xml 
<pool type='dir'>
  <name>images</name>
  <target>
    <path>/var/lib/libvirt/images</path>
  </target>
</pool>


# virsh pool-define pool-images.xml
Pool images defined from pool-images.xml

# virsh pool-start images
Pool images started


3. Run virt-install command that will try to create new disk in default storage pool:

# virt-install --name def-disk --memory 512 --import --disk size=1
ERROR    Error: --disk size=1: Storage pool not found: no storage pool with matching name 'default'


Then try to verify this bug with new build:
virt-install-2.2.0-2.el8.noarch
virt-manager-2.2.0-2.el8.noarch
libvirt-4.5.0-24.module+el8.1.0+3205+41ff0a42.x86_64
qemu-kvm-2.12.0-77.module+el8.1.0+3382+49219945.x86_64

Steps:
Rerun virt-install command that will try to create new disk in default storage pool:

# virt-install --name def-disk --memory 512 --import --disk size=1
WARNING  No operating system detected, VM performance may suffer. Specify an OS with --os-variant for optimal results.

Starting install...
Allocating 'def-disk.qcow2'

Result: No error reports, so I move this bug from ON_QA to VERIFIED.
