Shmmax & shmall warnings on LXD VM

Community Support

Hello,

Getting this error from an rpm that I wish to install on a LXD Centos 7 based image.

current shmmax: 18446744073692774399; required shmmax: 1261961216
current shmall: 18446744073692774399; required shmall: 308096

This LXD host is a physical host and not some VM.

Any idea what it could mean and what is suggested for a fix? Some settings maybe from LXD host side?

Maybe move from unprivileged to privileged and try again? Can a VM be switched between unprivileged<>privileged or need to start from scratch again creating VM?

Thanks ahead of time.

HI,

I haven’t seen that before, not sure what to do.

Can a VM be switched between unprivileged<>privileged or need to start from scratch again creating VM?

Technically yes, but it will result in an odd experience. You can find more info about this here
