Greetings, the circus is back in town -- another version of the guest page hinting patches. The patches differ from version 6 only in the kernel version, they apply against 2.6.29. My short sniff test showed that the code is still working as expected.

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

Hello, First of all, thanks very much for this piece of software, it's working like a charm. I'm using it to boot a Linux distro I'm working on. What I want to deal with is the display of accented characters in ISOLINUX. First, I set EXTLINUX up to boot an ext2-formatted USB stick. No problem so far. I wrote a config file ordering to load a font (lat-9w) to display french
