[xenpreview-dev] initial vm creation reports "not enough free memory" and xm info returns error "int exceeds XML-RPC limits"

[Fabio Sbano]

Can you remove this parameter 'dom0_mem=512M' grub?

restart the machine

you can see now 'xm list' will go display total memory you computer

try again start virtual machine after this change parameter.

I believe that you are using kernel-xenpae, ok?

Fábio Sbano
