If we use larger BIOS image than current 256KB, we would need move reserved
TSS and EPT identity mapping pages. Currently TSS support this, but not
EPT.

This was suggested but we thought it might be safer to keep the
get_cpu/put_cpu pair in case -rt kernels require it (which might be
bullshit, but nobody verified).

Make some small style changes to handling of pre- and post-commands.
These changes are not required, but they make the code slightly shorter and
more consistent with the rest of the code (IMO).
Also, do not print "Adding ... to environment" for each parameter in the
dict because in some cases there
'redirs' and 'vnc_port' might be used before they're defined, if
make_qemu_command() is called before create(). To make sure this doesn't
happen, define them in the VM constructor.

KVM would like to provide x2APIC interface to a guest without emulating

is that x2APIC interface is better virtualizable and provides better
