I should probably play with this myself, but due to lack of a test system where I can mess with systemd: Assuming we're on a s390x host (using KVM) and we specify: + <memory model='virtio-mem'> + <target dynamicMemslots='yes'> + <size unit='KiB'>2097152</size> + <node>0</node> + <requested unit='KiB'>1048576</requested> + </target> + </memory> In particular, without + <block unit='KiB'>2048</block> What would be the default value on a s390x host? In QEMU, we'd be using the default of 1 MiB on a s390x host, which corresponds to the THP size. Note that on an x86_64 host, the default will be 2 MiB. Ideally, we'd also be using the default of 1 MiB on an s390x host. How is the default value determined here? Thanks! -- Cheers, David / dhildenb
