Hello,
i have a little and the same Problem on “two” PC-Clients.
The Computers have 16 GB Memory, a brandnew installed OpenSuse 15.1 incl. Updates.
If the Computer boots without the “XEN Hypervisor” they are no Problems and the correct Memorysize displayed.
Boot the System with “XEN Hypervisor” only 2.2 GB Memory are displayed.
I remove 8 GB Memory and the Computer start with 8 GB Memory they only 1.7 GB are displayed!?
I tried a lot, kernel parameters, new installation and installed a Second System. Same Failure!
I’m also feeding Google wrong and I’m running out of ideas.
Some Systeminformations.:
# dmidecode 3.2
