More information in case it could help to isolate and solve the problem: - the problem could be related with a extrange incompatibility between the use of /dev/pts consoles and network kernel modules. Just making a "modprobe" of a network related kernel module after having used the pts console makes the virtual machine hang. I've tested with modules like wanrouter, pktgen, bridge, 8021q or ip_vs and all of them make the vm hang. However, loading other no network related modules work without problem (aes-i586, crypto-null or sunrpc). - I have made a quick test with kernel 2.6.23-rc4 and the behaviour is the same.
