I''ve taken a look in /tools/firmware. I''ve grepped for cpu and CPU. I don''t see something obvious to set the number of vcpus for a guest. All of the code seems as though it ought to deal with the vcpu setting. Anyway, if you, or anyone else, has a pointer to a particular file I''d be thankful.

hi, i''m having trouble booting with the areca raid driver. actually running debian sarge, i''m following the tutorial found at http://www.debian-administration.org/articles/304 my clean debian installation boots and finds up the areca drivers, i''m able to install the system on it, but after installing xen, the new kernel refuses to load the drivers (ending by a ''kernel panic'' sda1 couldn''t be found) is there something i''ve missed out ? should i include the areca driver in the xen kernel ? if someone could give me any clue, i''d really appreciate. regards, Cem Koker Unity Web Sàrl _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The 2.6.16.29 kernel does not have them by default. Be sure to build them with the compiler used to build the kernel, if using binary packages. The drivers themselves can be downloaded from Areca, and have very good instructions on how to install in or out of the kernel build. I have 5 of those cards in use, I am very, very happy with them :) Best, -Tim _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Areca''s RAID products are excellent in our experience and their support team is superb. - Roger _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
While reading http://wiki.xensource.com/xenwiki/XenRoadMap I found the following quote: "The current HVM code only stably supports uniprocessor guests, though work is underway to robustify SMP guest support." Could this be why I only see one processor in my HVM guests? Is it turned off by default someplace? I followed Mats directions and searched /tools/firmware and didn''t find anything obvious for enabling multiple vcpus. Any information would be greatly appreciated. If HVM is only uni-processor, that''s fine. I can live with that. (Hey, it''ll make me look harder at paravirtualization.) I''d just like to know.

It sounds like you are ready and willing to dig in and get dirty, which is great! Just don''t trust anything important to modified firmware. Just like you wouldn''t run anything vital on an untested overclocked system. Tinkering there can produce odd effects :) That being said its important that trial, error and success get documented in the list .. so please share your research with the list.> Any information would be greatly appreciated.

I''d just like to know. >Unless you need to virtualize something that simply will not work with the Xen 2.6 kernel, I''d really recommend working with paravirtualized guests for production stuff. HVM will get there soon, no doubt .. just not quite yet. Realize that HVM requires newer hardware that only a small percentage of this list has access to .. so you''ll also find the support for it a little slower than you would otherwise.> Thanks, > > Mark >Best, -Tim> _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
