virtManager: clone: build default clone path if we know how
I can reproduce this issue with package:
virt-manager-1.4.3-3.el7.noarch
Then try to verify this bug with new build:
virt-manager-1.5.0-3.el7.noarch
virt-install-1.5.0-3.el7.noarch
libvirt-4.5.0-12.el7.x86_64
qemu-kvm-rhev-2.12.0-26.el7.x86_64
libvirt-python-4.5.0-1.el7.x86_64
Steps:
1. Prepare a guest has two disks, one of them is readonly.
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/rhel7.6-1.qcow2'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</disk>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/rhel7.6-bios.qcow2'/>
<target dev='vdb' bus='virtio'/>
<readonly/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</disk>
1.1. Open virt-manager to clone the guest.
1.1.1 Launch virt-manager.
1.1.2 Choose the shutdown guest you want to clone and right click to choose 'clone'.
1.3. In Clone virtual machine dialog, choose 'Clone this disk' for the readonly disk.
1.4. Click 'clone' button.
Result: Clone is success,then start the new guest to check.
1.5 Check disk's configuration in guest's xml file
#virsh dumpxml rhel7.6-bios-clone
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/rhel7.6-bios-clone.qcow2'/>
<backingStore/>
<target dev='vdb' bus='virtio'/>
<readonly/>
<alias name='virtio-disk1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</disk>
Result:Virt-clone can prepare the default path for user when they want to clone ReadOnly disk.
Clone is success and the newly cloned guest can start successfully.
I move this bug from ON_QA to VERIFIED based on above testing.
