Benchmark LXD VMs

LXD

How can I benchmark LXD VMs, if it’s possible at all.
I tried one from the doc:

lxd.benchmark launch --count 10 worker-image

but without success:

[Jun  9 07:43:22.030] Failed to launch container 'benchmark-01':
Requested image's type "virtual-machine" doesn't match instance type "container"

Hi @mezobari,
Have you check it out the documentation? May be you should try with the init.
https://linuxcontainers.org/lxd/docs/master/howto/benchmark_performance/
And if the worker-image is the alias name of a vm then maybe the default case is looking for container image.
Regards.

if I understand it correctly, the tool only supports container not vm image.
lxd.benchmark --help
Regards.
