I am using KVM-88. However I can't get gdb still working. I stared qemu with -s -S option and when I try to connect gdb to it I get following error:- (gdb) target remote lochost:1234 lochost: unknown host lochost:1234: No such file or directory. (gdb) target remote locahost:1234 locahost: unknown host locahost:1234: No such file or directory.

If your host is running 64 bit mode but your target uses less, you need an extra patch [1] to deal with gdb limitations and a lacking workaround in qemu(-kvm).
