Re: Virtiofs xattr options on domain xml

Hi! I have a debian 11 (bullseye) machine running libvirtd version 7.0.0 and a RHEL 9 virtual machine that I need to share a disk and though about virtiofs. The disk is a btrfs disk and I have successfully mount it with:     <filesystem type='mount' accessmode='passthrough'>       <driver type='virtiofs' queue='1024'/>       <binary path='/usr/lib/qemu/virtiofsd' xattr='on'>         <cache mode='always'/>         <lock posix='on' flock='on'/>       </binary>       <source dir='/mnt/WD-Disk'/>       <target dir='media'/>       <alias name='fs0'/>       <address type='pci' domain='0x0000' bus='0x07' slot='0x00' function='0x0'/>     </filesystem> The problem I have is with selinux, when I try to change the context of a file inside the virtual machine I get a 'Operation not permitted' error, I can change the context in the Debian host and see the changes in the virtual machine but I would want to be able to change the context from the vm to able to use podman containers with selinux enabled. I see on the docs https://qemu.readthedocs.io/en/latest/tools/virtiofsd.html#selinux-support you can run virtiofsd with a xattr option so it is compatible with selinux but I do not find a way to change the domain xml to add this option, is there a way to add this option? Does a better option exists (maybe on the guest side)?
