[PATCH RFC] do_settime is backwards?!
While digging through the time code, I found something very strange
in do_settime:
x = (secs * 1000000000ULL) + (u64)nsecs - system_time_base;
y = do_div(x, 1000000000);
spin_lock(&wc_lock);
wc_sec = _wc_sec = (u32)x;
wc_nsec = _wc_nsec = (u32)y;
spin_unlock(&wc_lock);
The value "x" appears to be the number of nanoseconds, while

[BUG 1282] time jump on live migrate root cause & proposed fixes
Hi,
I have done some debugging to find out the root cause of bug 1282, which
has the following symptoms with paravirtualized guests:
- after a live migrate, the time on the guest can jump
- after a live migrate, the guest "forgets" to wake up processes
- after a domU save, dom0 reboot and domU restore, the time is
correct but processes are not woken up from sys_nanosleep
The problem

Re: Debugging Xen via serial console
Hi,
kdb: to debug xen hypervisor, could also debug guests
gdbsx: to debug PV/HVM linux guests
The tree is : http://xenbits.xensource.com/ext/debuggers.hg
See README-dbg. You''ll need to setup serial access for kdb.
Thanks,
Mukesh
