Description Prasad Pandit 2020-06-10 11:33:51 UTC 
Recently we received a few issues reported against block/vvfat.c driver.
Looking at

-> http://download.eng.bos.redhat.com/brewroot/vol/rhel-7/packages/qemu-kvm/1.5.3/175.el7/data/logs/x86_64/build.log

We currently build block/vvfat.o driver for virtual VFAT directory in

  rhel-6/qemu-kvm
  rhel-7/qemu-kvm
  rhel-7/qemu-kvm-ma
  rhel-7/qemu-kvm-rhev

However, these QEMU versions have a block driver's white list which states the drivers that are allowed to be used by a guest VM.

 Block whitelist (rw) qcow2 raw file host_device nbd iscsi rbd blkdebug luks null-co nvme copy-on-read throttle
 Block whitelist (ro) vmdk vhdx vpc https ssh 

./configure \
--block-drv-rw-hitelist=qcow2,raw,file,host_device,blkdebug,nbd,iscsi,gluster,rbd --block-drv-ro-whitelist=vmdk,vhdx,vpc,ssh,https

None of the list includes 'vvfat' format.

It'd serve good to remove 'block/vvfat.o' driver from qemu-kvm builds.
