Why is SELinux blocking virt-manager from reading my qcow2 file ?

[Sreyan Chakravarty]

I have a file for a Windows 10 VM in my home folder under a folder 
called virt-manager:

/home/sreyan/virt-manager/Windows 10-disk001.qcow2

When I try to switch on the VM from virt-manager it fails with:


SELinux is preventing worker from read access on the file 
/home/sreyan/virt-manager/Windows 10-disk001.qcow2.

*****  Plugin qemu_file_image (91.4 confidence) suggests *******************

If Windows 10-disk001.qcow2 is a virtualization target
Then you need to change the label on Windows 10-disk001.qcow2'
Do
# semanage fcontext -a -t virt_image_t 
'/home/sreyan/virt-manager/Windows.10-disk001.qcow2'
# restorecon -v '/home/sreyan/virt-manager/Windows.10-disk001.qcow2'

*****  Plugin catchall (9.59 confidence) suggests **************************

If you believe that worker should be allowed read access on the Windows 
10-disk001.qcow2 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'worker' --raw | audit2allow -M my-worker
# semodule -X 300 -i my-worker.pp

Should I just BLINDLY run the commands specified ? I don't want to be 
making exceptions that I don't understand fully.


Now what is strange is that it was working fine 2 days back. During that 
time I have not done any changes. No updates or whatever.

So why is this happening all of the sudden?

And why the hell is SELinux blocking a file in my /home ? It should be 
totally safe, why would anyone think this is suspicious ?
