My guest is a Fedora guest Fedora Core 2 includes a 2.6.5 kernel . I just tried to install newer kernel (through rpm install) and to modify clock kernel parameter with grub : kernel /vmli... clock=pit Next try : I'm installing a real linux partition on my hd to try with a Linux host. (I wonder if it's a windows host problem). PS1 : How can i determine what s going wrong with the clock (debug mode for qemu ?). What information could be usefull to debug the problem ?
