Title:
s390x guest hang when ipl boot from a mdev dasd
Status in QEMU:
Expired
Bug description:
qemu latest
kernel 5.3.18
I am using a passthrough dasd as boot device, the installment looks
fine and gets into reboot process. However VM could not boot and just
hang as below after that. I have been checking on "s390: vfio-ccw dasd
ipl support" series right now but no clue yet. Could anyone take a
look for it? Thanks.
