Hi all,

I have installed rhel 5.1 with xen 3.1 on a laptop and ALL is terrible slowly (network, mouse, etc.) If I starts with a normal kernel (without xen enabled) all works normally. Do I need to pass any param to grub on xen enabled kernel to all works ok??

Thanks ...
Laptops are always an adventure. Do you really have enough RAM? RHEL 5 is a bit of a RAM pig. Are you using all the CPU's, or only one? Is your hard drive an ATA drive that needs "hdparm" used to set it optimally? Tell us more!

My laptop have 1 GB of RAM, and it is Pentium M 2.0Ghz. for guests I only use one cpu. And another problem is clock: lost 5 minutes every 15 min.... runs so slowly on host ...
Umm. Not good. Are you running NTP on the Dom0, and being sure not to run it on your DomU? And how much RAM did you allocatae for DomU? RHEL 5 is really, really unhappy with less than 250 Meg, and not exactly thrilled with as little as 500 Meg.
