[Starlingx-discuss] Cannot allocate a VM - STX2.0-AIO-SX - Error500

[Mariano Ucha]

Thank you very much  Chris, now my VM is running. I have one question
because i try to allocate a vm with 512Mb and fails. But now i create a new
flavor with 1Gb of RAM.

My question is, Do I have to allocate so much hugepages like RAM i'll use
in my VM.

Thank you in advance.
Mariano
