Ubuntu Host - Windows Guest getting hung up only on REboot
I wrongly posted this earlier and said it happened "on boot". This only happens during a REboot where you are in the Windows guest and do a restart. It hangs every time at the image shown here. If I hard shut off the guest at this point I can start the machine with no problem every time. Has anyone else grappled with this and found the cause of it?

fio fdp mode with qemu emulated nvme
Hi, I have problem using fio with fdp mode (flexible data placement) in qemu guest...Anyone knows how to do it successfully? Many thanks! I have used very recent code of fio and qemu, in which already include fdp related commits.fio: commit b311162cqemu: commit 0d52116fguest os: ubuntu 22.04, with default kernel v.5.15.0-43-generic Here are the commands I use:1. qemu# qemu-system-86_64 -hda ubuntu.qcow2 -boot d -net nic -net user -m 16384 -smp 8 -cpu host -enable-kvm \ -device nvme-subsys,id=nvme-subsys-0,nqn=subsys0,fdp=on,fdp.nrg=3,fdp.nruh=16,fdp.runs=96M \ -device nvme,id=nvme0,serial=mynvm,subsys=nvme-subsys-0 \ -drive file=nvm-1.qcow2,id=nvm-1,if=none \ -device nvme-ns,drive=nvm-1,fdp.ruhs=0-15,bus=nvme02. fio# fio --ioengine=io_uring_cmd --cmd_type=nvme --filename=/dev/ng0n1 --fdp=1 --fdp_pli=0-15 \ --iodepth=1 --direct=1 --rw=randwrite --bs=4K --size=1G \ --runtime=10 --time_based --group_reporting --name=job1 Then fio fails, error:fio: pid=1884, err=22/file:engines/io_uring.c:1089, func=io_queue_init, error=Invalid argument So I traced code and found this error occurs at syscall(__NR_io_uring_setup, depth, ) in fio_ioring_cmd_queue_init() of fio/engines/io_uring.c(Here: https://github.com/axboe/fio/blob/b311162c37a2867873e1222ce6b5f38c88be4d80/engines/io_uring.c#L955 )The variable p is a struct io_uring_params, so I print its content right before the syscall(): sq_entries=0, cq_entries=1, flags=15624, sq_thread_cpu=0, sq_thread_idle=0, features=0, wq_fd=0, resv[0]=0, resv[1]=0, resv[2]=0sq_entries=0, cq_entries=1, flags=3336, sq_thread_cpu=0, sq_thread_idle=0, features=0, wq_fd=0, resv[0]=0, resv[1]=0, resv[2]=0sq_entries=0, cq_entries=1, flags=3080, sq_thread_cpu=0, sq_thread_idle=0, features=0, wq_fd=0, resv[0]=0, resv[1]=0, resv[2]=0sq_entries=0, cq_entries=1, flags=3072, sq_thread_cpu=0, sq_thread_idle=0, features=0, wq_fd=0, resv[0]=0, resv[1]=0, resv[2]=0 Still can't figure out what's wrong...Finally, I suspect my io_uring library is too old to support fdp?So I make install the latest liburing (https://github.com/axboe/liburing), but still same fio failure. Mant thanks!
