Summary: network issue of 64bit linux guest

Initial Comment:
Environment:
------------
HOST (ia32/ia32e/IA64): ia32e
GUEST (ia32/ia32e/IA64): ia32e
COMMIT: 21bd205a4c38c06d25f93f20b0e6b26c75f84f44-1edeb9c05aa034633978f31e2c773a1be55ed337
Hardware: harwich/paxville



Bug detailed description:
--------------------------
Network of 64bit guest will be lost while copying small files from guest to host with scp command. 

error info on host:
[root@localhost ~]# scp ly test temp* 192.168.134.37:/root/
ssh: connect to host 192.168.134.37 port 22: No route to host
lost connection

error info on guest:
[root@localhost ~]# scp ly test temp* 192.168.199.79:/root/
ssh: connect to host 192.168.199.79 port 22: No route to host
lost connection

Coping from host to guest has't this issue.
And 32bit guest hasn't this issue

This can be worked around with '-no-kvm-irqchip' for kvm or 'noapic'  on 
the guest kernel command line.  Looks like a bug in ioapic emulation.

Should now be fixed in kvm.git.
