      Description
      Should allow read only mode for virtiofs from libvirt side. Read only mode for virtiofs has just been supported by virtiofsd: https://issues.redhat.com/browse/RHEL-9930
       
      How reproducible:
      100%
       
      Versions:
      libvirt-10.10.0-2.el9.x86_64
      virtiofsd-1.13.0-1.el9.x86_64
       
      1. Prepare a guest with following xml

      # cat lizhu.xml
...
   <filesystem type='mount' accessmode='passthrough'>
      <driver type='virtiofs' queue='1024'/>
      <binary path='/usr/libexec/virtiofsd' xattr='on'>
         <cache mode='always'/>
         <sandbox mode='namespace'/>
         <thread_pool size='16'/>
      </binary>
      <source dir='/path'/>
      <target dir='mount_tag'/>
       <readonly/>
  </filesystem>
...
 

      2. Define the guest

       # virsh define lizhu.xml 
error: Failed to define domain from lizhu.xml
error: unsupported configuration: virtiofs does not yet support read-only mode

       
      Expected result:
      virtiofsd had supported read only mode. We should support either.
