Hi Kleber,
The error KVM: Failed to create TCE64 table for liobn 0x... is harmless
so let's forget it.
I tried hard to reproduce the error without success so far, so I'm going
to ask you another favor. Could you generate a trace

@Breno
Did you notice that error (KVM: Failed to create TCE64 table for liobn
...) in your logs as well? The log in #comment 10 is not complete.
I'm not sure if the problem that Kleber is facing is the same pointed by
Breno.

I was talking to Kleber and he's getting some errors like:
KVM: Failed to create TCE64 table for liobn 0x7102
KVM: Failed to create TCE64 table for liobn 0x8000
TCE is responsible to translate IO address to physical
