I'm trying to configure GRUB to allocate fixed amount of dedicated memory to dom0, according to this best practices thread (http://wiki.xensource.com/xenwiki/XenBestPractices | "Xen dom0 dedicated memory and preventing dom0 memory ballooning "). When I reboot, dom0 has the fixed amount of memory as it was configured, but neither xm info shows the rest of memory available for the Hypervisor, nor can start domUs (due to lack of memory). For me it seems that the memory over the configured dom0_mem parameter is somehow invisible to the Hypervisor and both dom0/dumUs are unable to use it.

Is the given best practices article broken, or am I missing something?
