I installed and configured KVM on a HP Zbook 15 laptop with 2x4 CPUs and
24GB of memory
OS is Debian bullseye
No matter what I try, any VM with > 1GB virtual memory gives an error
message on start:
Cannot set up guest memory,'pc.ram': invalid argument.
In the target XML file, the amount of memory (I need 12GB for my VM) is
expressed in KiB and appears correct.
Any suggestions?
