Hi, my name is Bruce. I have been using Linux for several years and toying with VMWare and looked at User Mode Linux. I discovered Xen a few days ago while reading a recent issue of Linux Weekly News. I installed Xen lastnight and joined this list att. I am currently running SuSE 9.1 Linux on a custom machine made my Monarch Computer with a Tyan motherboard, 2 Althon MP 2GHz processors, 1GB of RAM and three SCSI HDDs. From what I understand Xen cud be what I have been looking for. I got the Xen 2.6.9 kernel booted with only two minor problems I have resolved. 1. I did not understand the dom0_mem value and set too low. When I increased it, the kernel booted just fine. 2. my USB trackball would not work, but when I plug it into a PS/2 port, with works just fine. Now for my questions 1. Is "Domains" in Xen speak the same as Virtual Machines in VMWare speak? 2. I read that various OS''s need to be ported to work with Xen, but I can''t find out how or what needs to be done when reading the Xen manual. I have a 9GB HDD ready to format and use for ported OSs.

> Now for my questions > 1. Is "Domains" in Xen speak the same as Virtual Machines in VMWare speak?Yes, or has very similar meaning. At least I think so :-) Domain0 is the same as the "host OS" in VMware, another domains are "guest OSes".> 2.

"Porting xen" means rewriting some machine-dependent parts of OS'' kernel code to work under xen. This is job for experienced programmers, not for you. Linux has been ported already :-), so you won''t have to bother with it. j. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

If you enable USB support your xen0 kernel, it should work fine.> 1. Is "Domains" in Xen speak the same as Virtual Machines in VMWare speak?Basically less. Technically, we call a "virtual machine" the persistent entity with configuration, virtual disks, etc. We call a *running* virtual machine a domain. This is like the distinction between programs and processes that many OSs have.> 2. I read that various OS''s need to be ported to work with Xen, but I can''t > find out how or what needs to be done when reading the Xen manual. I have a > 9GB HDD ready to format and use for ported OSs.There''s some guidelines on porting OSs in the interface manual. Note however that only the operating system kernel needs modification - this has been done already for Linux 2.4 / 2.6, NetBSD, FreeBSD and Plan 9.

Experienced programmer would probably read the "Developer Manual" first :-). Well, it was a guess, but (according to private correspondation with original poster) true. j. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
