Hence I needed ''full virtualization'' (I think).

I certainly need to do some more reading. http://www.virtuatopia.com/index.php/Xen_Virtualization_Essentials seems worth it but a little out of date?> >>> New to Xen. >>> Confused about the base architecture. > Just try it - If you want to dig a little bit deeper then ideally by play around with the xen and kernel sources byself...One Linux is enough for me (bear of tiny brain). I need windows for odd apps, and am curious about Windows 7, it''s getting a good reputation.> >>> implies that xen runs closest to hardware > yes, a little bit like your BIOS too...Nearly. Long time back I wrote an OS for some dedicated hw, in assembler, with all its drivers. I''m fairly happy next to the hardware.. .Just not with the x86 setup and it''s VT ideas.> > >> My assumptions probably.

Tks. Also found another workaround for the tools/curl problem. http://forums.fedoraforum.org/showthread.php?t=234928 Workaround: disable libcurl.so.4 in VMWare, e.g. mv /usr/lib/vmware/lib/libcurl.so.4 /usr/lib/vmware/lib/libcurl.so.4.DISABLE P.S. Leave the certs untouched, you can install the vmware tools. HTH others. -- Dave Pawson XSLT XSL-FO FAQ.

Windows arrived this moring. Now installing. Only disappointment, I have a spare disk set up for it, I wasn''t given the choice of ''which'' disk to install the OS. Is that needed in the config file before I start to install please? Dave -- Dave Pawson XSLT XSL-FO FAQ.

Your previous post contains references to vmware, I''m not sure which system you installed it on. How do you install it? using virt-manager? editing config files manually? if you edit config file, there''s a section called "disk". For example, in my setup I use this disk = [ ''phy:/dev/rootvg/win01lv,hda,w'', ] I use LVM as domU/guest backing storage. If you have a spare drive (e.g. sdb) and want to use it ONLY for Windows guest, you could use something like disk = [ ''phy:/dev/sdb,hda,w'', ] or, since you already use Vmware, you can just store domU''s disk images as files (similar to vmware). Format the spare disk and mount it as /var/lib/xen/images (or whatever path you like, as long as you also make sure that things like selinux and permissions match), and use something like this on domU config file disk = [ ''tap:aio:/var/lib/xen/images/win01.img,hda,w'', ] if you use virt-manager it asks you where you want to put domU''s disk image. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
