Re: qemu-img create Timeout on 'nvme://'

[Pascal]

hi,

I discover this way (URI nvme://...) with your question.
according to the documentation (https://qemu.readthedocs.io/en/latest/system/images.html?highlight=nvme#nvme-disk-images), the access is exclusive : wouldn't there be another process that would monopolize the device ?

regards, lacsaP.

Hi,

When I'm trying to create a image on nvme disk, i get an error message that says:

➜  ~ qemu-img create -f qcow2 nvme://0000:87:00.0/1 1G

Formatting 'nvme://0000:87:00.0/1', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=1073741824 lazy_refcounts=off refcount_bits=16

qemu-img: nvme://0000:87:00.0/1: Timeout while waiting for device to start (20000 ms)

Any ideas where to look?

Below are info about the disk

➜  ~ qemu-img info nvme://0000:87:00.0/1              
image: nvme://0000:87:00.0/1
file format: raw

➜  ~ lspci|grep non-v -i
