adb unable to connect to Android-x86 in VirtualBox today

Question

I WAS successfully installed Android-x86-v3.2-eeepc in VirtualBox for a while. And it is a good method to help me to debug USB host applications on Android. The installation of such configuration is:

• Install VirtualBox
• Install Android-x86-v3.2-eeepc image into virtual HDD in VBOX
• Set network as "host-only"
• Enter console, type "dhcpcd eth0" to get IP address, like "192.168.56.101"
• Go to console of host, type "adb connect 192.168.56.101"

Normally, it should be all right to get connected to adb daemon running in Android-in-VBox.

Today, it suddenly prompts me as following:

C:\>adb connect 192.168.56.101
unable to parse 192.168.56.101 as <host>:<port>

I tried to ping its IP. It has a fast response. I tried to enforce IP and port.

C:\>adb connect 192.168.56.101:5554
unable to connect to 192.168.56.101:5554

I have no idea about its root cause. I checked the firewall, VirtualBox is on the Exception List. It still doesn't work.

PC Configuration: Windows XP VirtualBox V4.1
