The system keeps running but all vserver* scripts hangs after the crash.
A reboot will fail because the vserver* scripts hangs only a hard reset

i have defined a VARIABLE REALBLOCKDEVICE in v01.conf and handle the
vrsetup in /etc/init.d/vservers. The cqhadd/cqhrem is doing in v01.sh.
It's not so good because the REALBLOCKDEVICE is "hardcoded" in conf
file, but it works
