QEMU will not boot #44

Closed sooyun802 closed 6 years ago

sooyun802 commented 6 years ago

Hello, I am currently using the following options to boot my VM.

sudo $HOME/qemu-nvme/bin/qemu-system-x86_64 -m 4G -smp 4 -s \
-vnc :4 \
-drive file={path to vm image},id=diskdrive,format=raw,if=none \
-device virtio-blk-pci,drive=diskdrive,scsi=off,config-wce=off,x-data-plane=on \
-drive file={path to ocssd backend file},id=myocssd,format=raw,if=none \
-device nvme,drive=myocssd,serial=deadbeef,lnum_pu=4,lstrict=1,meta=16,mc=3

This is what it looks like when I execute the command.

Are there any more options I need to add to get this to work?

Thank you.

Looks like you're missing your os image or something to boot from. Did you create an OS image to as the "path to vm image"?

sooyun802 commented 6 years ago

Yes, and I know it should work because it worked with FEMU.

Ok. Instead of

-drive file={path to vm image},id=diskdrive,format=raw,if=none \ -device virtio-blk-pci,drive=diskdrive,scsi=off,config-wce=off,x-data-plane=on \

You can try:

-hda {path to vm image} \

Then the virtio acceleration is disabled.
