[SOLVED] Virt-manager could not open Win10 ISO: Permission denied

Hi everyone, hope you're doing well, so I'm having a problem with virt-manager where I hit the "Begin Installation" button it throws this error:

Unable to complete install: 'internal error: process exited while connecting to monitor: 2022-01-10T02:38:55.112690Z qemu-system-x86_64: -blockdev {"driver":"file","filename":"/home/max/Downloads/Win10_21H2_English_x64.iso","node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}: Could not open '/home/max/Downloads/Win10_21H2_English_x64.iso': Permission denied'

Just for the record, I've already done most of the preparations needed to run a KVM (including the package ovmf for UEFI support, the process of enabling libvirtd, setting up a network though virsh and do the configuration in the XML before opening the VM for the CD-ROM and configuring the topology of the CPU and enabling UEFIx86_64) I tried to search the problem and found that people solved a similar problem installing the ovmf package (which I already had installed) so I'm clueless of what to do to solve this, I also tried changing the permissions of the "Downloads" directory where the ISO is kept, but that didn't do anything.

If there is any information I forgot to bring here just comment it and I gladly share it. Thanks for reading and hope you respond

What are the perms of the ISO itself? Have you tried putting it somewhere more "global" rather than the home dir where a potential daemon can't access it? Did you see https://wiki.archlinux.org/title/Libvir … entication ?

Just from a "errors" perspective this seems pretty simple, the daemon you use can't access the file you pass.

Oh, I didn't think of the perms of the ISO itself, sorry about that.
And it works when I move out of the home dir thank you so much!! I didn't know that the daemon can't access the home dir, I thought that adding the user to libvirt and enabling the services was enough.
