How to reserve the advanced option in ova when import image to VIO?

Hi expert,

I have a ova image with some advanced option for VMXNET3 nic. (the advanced options are ctxPerDev which used to improve the TX performance of VMXNET3 nic)

But when I import this image to GLANCE, the advanced options are discarded. I can verify it from the vmtx file in the vCenter.

I know in vCloud Director (before V8.10 version), the advanced options can't be reserved either only if you add the whitelist of this option in the database of vCD manually.

So I want to know is there any method simular in VIO3.0, to reserve the advanced option that I need ?

Thank you very much!

BR.

Haifeng.

Hi,

Unfortunately, not all OVA properties are preserved on VIO.

If you are looking specifically to configure 'ctxPerDev', it can be set using flavor extra spec.

hw:vifs_multi_thread='true'

nova flavor-key <flavor-id> set hw:vifs_multi_thread='true'


If your apps are sensitive to latency, then I recommend latency sensitivity feature.

vmware:latency_sensitivity_level='high'


nova flavor-key <flavor-id> set hw:vifs_multi_thread='true' vmware:latency_sensitivity_level='high'
