Re: about hot plug issue

Any extreme case is going to stress the crap out of the dom0
hotplug subsystem; it's not clear it was designed for the sort
of workloads xen puts on it :-(

BTW, your attachment was stripped, but I think we can probably
work out what it does.

cheers,

Subject: about hot plug issue


We found that cs 11554 increases some of timeout to fix
the hot plug issue when starting 4 VMX simultaneously.
Thanks for the quick reponse to nightly status report.

But we found that when in an extremely condition, like
creating 12 VMX domains and 4 XENU domains at the same
time, sometimes we still can meet this bug. Attached is a
demo script to start many domains. So we just wonder changing
the timout value could not resolve this issue completely.
At the same time, we found when main_loop_wait is increased to
100 ms, windows guest's keyboard and mouse response is
significantly slower.
