Hi, Dan,
With attached patch, I can "xend start" successfully now and
finally domU reached xen_init from the serial output:
NET: Registered protocol family 16
Running on Xen! start_info_pfn=0x0 lags=0x0
xen-event-channel using irq 233
store_evtchn = 1
Then domU falls into a dead loop to acquire spinlock of printk
buffer (already held by others), and strange thing is that machine timer
interrupt still happens while domain switches disappeared.
I'll go to Intel IDF (Shanghai) at the rest of this week, and so
can't find enough time to continue debug. Dan, could you take over the
domU boot? ;-) Actually the start_info_pfn is problematic point here,
since it should be passed from control panel.
Thanks,
Kevin
