--- Comment #17 from Jan Beulich
Jan, especially with the heavy i/o load case, do you think it's possible that guests aren't getting scheduled? I'm not suggesting it's a Xen bug since we see the same problem with Parallels - but perhaps it's a load issue?
Heavy load can certainly cause latency issues, but in the tens-of-milliseconds range, not many seconds (which would imply that several time slices of - by default - 30ms don't suffice to get enough non-interrupt work done in the guest to have the soft lockup timer run at least once). That is of course unless - the system is insanely overcommitted, in which case this wouldn't be a bug at all, or - all of the time is spent in handling interrupts in the guest. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
