[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 th...

[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 > > Hi Dan, > > I''m currently using your version of ssplitd as it is. I haven''t tried > kdb. For some reason I
