1. Create images with different formats.

qcow2:

# qemu-img create -f qcow2 gluster://10.73.196.181/gv0/test1.qcow2 20G

2.  Install guest over a image with qcow2 format, reboot, and shutdown.

/usr/libexec/qemu-kvm \
        -name 'guest-rhel' \
        -machine pc \
        -nodefaults \
        -vga qxl \
        -drive id=drive_cd1,if=none,snapshot=off,aio=threads,cache=unsafe,media=cdrom,file=/home/RHEL-7.8-20200225.1-Server-x86_64-dvd1.iso  \
        -device ide-cd,id=cd1,drive=drive_cd1,bus=ide.0,unit=0 \
        -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=qcow2,file=gluster://10.73.196.181/gv0/test1.qcow2 \
        -device virtio-blk-pci,id=virtio_blk_pci0,drive=drive_image1,addr=05 \
        -vnc :0 \
        -monitor stdio \
        -m 8192 \
        -smp 8 \
        -device virtio-net-pci,mac=9a:b5:b6:b1:b2:b3,id=idMmq1jH,vectors=4,netdev=idxgXAlm,addr=0x9  \
        -netdev tap,id=idxgXAlm \
        -chardev socket,id=qmp_id_qmpmonitor1,path=/var/tmp/timao/monitor-qmpmonitor1-20180220-094308-h9I6hRsI,server,nowait \
        -mon chardev=qmp_id_qmpmonitor1,mode=control  \


Result:
Creation works fine, and install,reboot, shutdown all work fine.
