Jim,
what is the actual problem? I've tried to reproduce this by running vm
with 3.5G RAM backed by 1GB huge pages and the guest runs just fine. I
mean kvm guest. This is because at the cmd line level there is aligned
value:
-m size=4194304k,slots=16,maxmem=8388608k
This is result of qemuDomainAlignMemorySizes(). So perhaps there's a bug
somewhere in the function?
Quite possibly. Some memory values work fine and appear to be rounded
to the next gigabyte boundary. One KiB values that fails for me is,
<memory unit='KiB'>52428801</memory>
<currentMemory unit='KiB'>52428801</currentMemory>
Which results in qemu-kvm ... -m 51201
