Hi,

I'm running it under ESX and I've configured it with 2 GB Memory and a 30GB Disk.

I guess it's ok to configure the VM just like it says in the release notes.
http://up2date.astaro.com/ACC_V1.9_ReleaseNotes.pdf on Page 6.

VMware Tools are included in the ISO so it's ok to install it from there.

Hope that helps.

Regards,
Henrik
