Reproduce with:
virt-manager-2.0.0-5.el8.noarch
virt-install-2.0.0-5.el8.noarch
Verify with:
virt-install-2.2.1-1.el8.noarch
virt-manager-2.2.1-1.el8.noarch
libvirt-4.5.0-31.module+el8.1.0+3808+3325c1a3.x86_64
qemu-kvm-2.12.0-82.module+el8.1.0+3738+0d8c0249.x86_64
Steps:
Scenario-1
1. Prepare a guest which has a cdrom disk and no path is set to the cdrom.
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<target dev='sda' bus='sata'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
2.Force copy the cdrom device during virt-clone.
2.1
# virt-clone -o rhel7.7-clone -n rhel7.7-clone-new --auto-clone --force-copy sda
Allocating 'rhel7.7-clone-new.qcow2' | 7.0 GB 00:00:02
Clone 'rhel7.7-clone-new' created successfully.
2.2
#virsh dumpxml rhel7.7-clone-new.qcow2 | grep disk
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/rhel7.7-clone-new.qcow2'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
</disk>
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<target dev='sda' bus='sata'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
Results:Cloning finishes successfully with the empty cdrom device and new guest can start successfully.
Scenario-2
1.Prepare a guest which has a floppy disk and no path is set to the floppy disk.
<disk type='file' device='floppy'>
<driver name='qemu' type='raw'/>
<target dev='fda' bus='fdc'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
2.Force copy the floppy device during virt-clone.
2.1
# virt-clone -o rhel7.7-clone -n rhel7.7-clone-fdc --auto-clone --force-copy fdc
Allocating 'rhel7.7-clone-fdc.qcow2' | 7.0 GB 00:00:02
Clone 'rhel7.7-clone-fdc' created successfully.
2.2
# virsh dumpxml rhel7.7-clone-fdc | grep disk
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/rhel7.7-clone-fdc.qcow2'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
</disk>
<disk type='file' device='floppy'>
<driver name='qemu' type='raw'/>
<target dev='fda' bus='fdc'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
Result:Cloning finishes successfully with floppy disk attached and new guest can start successfully.
So I move this bug from ON_QA to VERIFIED.
