Summary0016891: qemu-kvm-2.12.0-88.module_el8.1.0+248+298dec18.x86_64 write error when using nfs as storage
Description i use Centos8 stream and installed current version qemu-kvm. qemu-kvm-2.12.0-88.module_el8.1.0+248+298dec18.x86_64. when i use file in nfs dir as qemu-kvm storage , the guest machine appears many write error.
when i removed qemu-kvm-2.12.0-88.module_el8.1.0+248+298dec18.x86_64 and installed qemu-kvm-2.12.0-64.module_el8.0.0+44+94c1b039.2.x86_64, the problem disappered.
so I guess there are some bugs in qemu-kvm-2.12.0-88.module_el8.1.0+248+298dec18.x86_64
