Hi!
This is my first post here so please bear with me; we have a Debian
Lenny system with kernel 2.6.28 and kvm-84, and can't start a guest
with
more than 3536 MB Ram. With kvm-72 (the version lenny released with) we
can use all 7GB that is intended for that guest.
(...)
qemu: loading initrd (0x781b93 bytes) at 0x000000007f87e000
create_userspace_phys_mem: Invalid argument
kvm_cpu_register_physical_memory: failed
And back to the console. When I try the same with 3584MB, I can boot
into the machine flawlessly.
Sorry for getting the numbers wrong in the first mail - the actual
problem starts at 3585MB Ram for the guest.
If you can't reproduce it with yout 2.6.28 and kvm-84, I should possibly
take this to the debian bugtracker ...
kvm-72 is pretty old. It used to be that we used phys_ram_base for
loading kernel/initrds which would break when using > 3.5GB of memory.
I wouldn't be surprised if that fix happened post kvm-72.
Doesn't he say that it did work for him with kvm-72, but does not with
kvm-84?
