It's not permissinos, it's ownership. Kvm/qemu/qemu-kvm does not
touch permissions and ownership of existing files.
I'm not sure if it's virt-manager or libvirt or whatever issue, since
I know nothing about that part of the game.
But to me the issue looks quite serious: starting a vm makes some
files owned by root not by user. This might well be a security
issue that needs further investigation.
Reassigning the bug to virt-manager and Cc'ing to
[email protected].
Thanks.
