Hi,
I found one weird thing: I heard RAMDISK is not required for domU, but it
seems I have to add RAMDISK to my domU config file, otherwiese the domU
will hang up when it is booting. Please see the message below, the domU
booting hangs up after "Continuing..."
Does anyone have any clue for this issue? BTW, xen-friendly glibc is already
installed.
Thanks,
Liang
