[GitHub] [cloudstack] ustcweizhou opened a new pull request #4656: Ubuntu 20.04: set Backing Format of qcow2 images in vm start and migration
ustcweizhou opened a new pull request #4656:
URL: https://github.com/apache/cloudstack/pull/4656
### Description
This PRs fix issue when fails to start or migrate vm after upgrade to ubuntu 20.04, by setting backing file format of qcow2 images.
In previous cloudstack versions, qcow2 image does not have a backing file format.
however, it is required in newer qemu versions, for example qemu 4.2 on ubuntu 20.04.
steps to reproduce the issue
(1) install cloudstack 4.14 or previous version, and ubuntu 19.04 or 18.04/16.04 LTS.
(2) create vms.
(3) upgrade to 4.15, upgrade os to ubuntu 20.04 , or install a new server with ubuntu 20.04.
(4) migrate vm from old ubuntu version to ubuntu 20.04, failed with exception below
```

```
(5)stop vm, and start it on ubuntu 20.04 server. failed with exception below
```

```
To make testing easier, step 1 and 2 can be replaced by
```
qemu-img create -f qcow2 -b <backing file> <qcow2 image>
```
so qcow2 image does not have a backing file format.
