[kvm-devel] VM entry/exit time

it takes almost 3 times longer on the Lenovo to make a vmcall. Anyone have any idea what might be causing this? Running kvm on suse10.2 on both the systems. Thanks Omar Khan - This SF.net email is sponsored by DB2 Express

[kvm-devel] unix lite

hi, I am trying to run unix like operating system (mainly meant for educational purposes) on kvm called "Unix Lite" (http://www.unixlite.org/). It runs fine on qemu but on kvm it gives the unhandled vm exit 0x9. This is caused by the hardware task switch that is used in unix lite. The code

[kvm-devel] unhandled vm exit: 0x9

hi, I am trying to run an experimental operating system 'Choices' on kvm and it is giving me the 'unhandled vm exit: 0x9' error. It runs fine with the -no-kvm switch though. In an earlier post (http://article.gmane.org/gmane.comp.emulators.kvm.devel/ 654/match=unhandled+vm+exit) Avi said that

[kvm-devel] vmcall time

hi, What is an easy way to approximately measure the time it takes to make a vmcall? If I make let us say 100,000 vmcalls from the guest os and print jiffies in kvm for the first and last call would that do the job? Thanks Omar --

[kvm-devel] paravirtualization

The paravirtualization announcement by Ingo Molnar said that: - it provides an ad-hoc paravirtualization hypercall API between a Linux guest and a Linux host. (this will be replaced with a proper hypercall later on.) Is it possible to modify a non-linux guest to take advantage of this hyperc

hi, "make install" does not install the modules in the right directory (actually it is not making the 'extra' directory). I changed KERNELDIR ?= /lib/modules/$(shell uname -r)/build to KERNELDIR := /lib/modules/$(shell uname -r)/build in the kernel/Makefile and it is working now
