Hi,

If using the virtio-blk drivers version 0.1.141 are used nothing crashes
but the disk is not found...

My config:

loader="uefi"
cpu=2
cpu_sockets=1
cpu_cores=2
cpu_threads=1
wired_memory="yes"
memory=8G
virt_random="yes"
network0_type="virtio-net"
network0_switch="private"
disk0_type="nvme"
disk0_dev="zvol"
