[ovirt-devel] VDSM faqemu default memory change

[Martin Polednik]

Hello

I'm writing in order to propose a change to faqemu hook as indicated in [1],
modifying the hook's default behavior:

There are currently hardcoded x86_64 and PPC memory limits (20480 and 262144),
this change would remove these implicit constraints and keep the memory unchanged.
A new variable in configuration is introduced, fake_kvm_memory, which allows you
to limit the memory for both these platforms to a value (or using unchanged memory
by setting it to 0, which is default).

This means that running faqemu without modification would consume up to 10x times
memory using default VM memory memory size for x86_64 and unchanged for PPC.
