Currently able to accelerate Linux guest on VMware (by using hypercalls), because only VMware uses them. Because those two technologies are open-standards, other OSS projects will use them soon. They are not VMware specific in concept, otherwise mainline kernel would never agree to integrate them. Xen may use those standards soon, and other teams will follow later... There are no OSS user-space utilities, that I know of. OS-level virtualization: Those technologies are part of Linux VServer and OpenVZ projects. This is not complete solution as of yet, so it won't work by itself, but it may enable easier installation of OpenVZ in the future. Currently, installing OpenVZ (kernel) on openSUSE is extremely difficult task, due to huge number of kernel patches it requires. Not all of OpenVZ is in mainline, but some parts are. Currently full kernel rebuild is required. I hope that enabling those features will make it easier in the future to install "OS-level virtualization" products without full kernel rebuild. OpenVZ user-space utilities are OSS and easy to install. (but they don't work without the kernel part) Overall: At this point of time, the changes will be negligible (very small). Another reason for enabling those technologies, is that we want to be ready for upcoming technologies. History: in SUSE 10.2 we mistakenly disabled CONFIG_USB_DEVICEFS, which resulted in serious hit for Virtualization products (VMware, VirtualBox and maybe Qemu) not able to use USB on SUSE 10.2 systems. https://bugzilla.novell.com/show_bug.cgi?id=210899#c47 I would like to prevent such a case (like 10.2) where upcoming virtualization technologies aren't supported by SUSE. P.S. I would like to see complete integration between OpenVZ and openSUSE, not just on kernel level, but also in GUI and documentation levels... but it's just a dream... :) -- 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, or are watching someone who is.

No packages are needed at all, just this kernel config option and then performance and scalability for Linux in a VM increase dramatically. -- 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.

Is this an i386 thing only? If not, it isn't clear how to enable it.

Yes, VMI is only for i386 (32-bit). -- 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.
