Public bug reported:
Guest XML
virt-clone fails on a suspended (paused) guest, whereas documentation claims
the clone should be successful.
---uname output---
Linux T257KVX 5.4.0-21-generic #25-Ubuntu SMP Sat Mar 28 13:10:00 UTC 2020
s390x s390x s390x GNU/Linux
Machine Type = Type: 8562 Model: A00, LT2
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1. Create a guest
2. Suspend it by running the following: virsh suspend <guest>
3. Verify that the guest has paused.
4. Attempt to clone it: virt-clone -o <suspended_guest> -n <new_guest>
--auto-clone
Observe the error:
ERROR Couldn't create storage volume '<new_guest>.qcow2': 'internal error:
Child process (/usr/bin/qemu-img convert -f qcow2 -O qcow2 -o
compat=1.1,lazy_refcounts /guestimages/<suspended_guest>.qcow2
/guestimages/<new_guest>.qcow2) unexpected exit status 1: qemu-img: Could not
open '/guestimages/<suspended_guest>.qcow2': Failed to get shared "write" lock
Is another process using the image [/guestimages/<suspended_guest>.qcow2]?
'
Even though the virt-clone --help documentation claims the following:
General Options:
-o ORIGINAL_GUEST, --original ORIGINAL_GUEST
Name of the original guest; The status must be shut off
or paused.
And when one tries to clone a running guest, they are given the following
message:
ERROR Domain with devices to clone must be paused or shutoff.
It is worth noting that this operation is successful on a guest that is shutdown
