Missing memory
-
Hello, I have total of 32GB ram installed.
During the installation of the system, I had 16GB installed. Much later, I decided to add an additional 16 GB. The problem is that Xen only shows16 of 32 GB. In spite of the new ones works correctly (BIOS displays total 32 and dmidecode shows 4 banks for 8 GB), they weren't correctly recongnised and added by OS
xsconsole displays 16GB
