Hi, I just want to have the confirmation of something that i was asked for. Some colleagues wanted to know if it was possible for the owner of a DomU (who doesn''t have any access to the dom0 host) to recompile his domU kernel in order to customize the options. I have answered him that it was not possible because the domU kernel was on the dom0 /boot directory but I wanted a confirmation in order to be sure that I have not said any errors. Thanks for your help, Guillaume Thiery _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I think they can because the files in on the /boot directory of their own partition.

Hi, i''ve never used it, but via pygrub this should be possible. As far as I know, pygrub uses a menu entry at domU''s /boot directory and also loads the kernel from this place. I could be wrong, but this way, the owner of a domU is able to use his own kernel (as long as it''s valid for the host architecture (PAE/64bit vs non-PAE) and contains the xen- patches. A vanilla kernel will probably not work. If you want to give full access to the domU owner, use HVM domU''s. cheers, Stephan Guillaume Thiery schrieb:> Hi, > > I just want to have the confirmation of something that i was asked for. > Some colleagues wanted to know if it was possible for the owner of a DomU > (who doesn''t have any access to the dom0 host) to recompile his domU kernel > in order to customize the options.

This is acheived (for example) by installing domUs from a regular distrib tree using virt-install. By this way, domU owners see a more regular machine, that has and uses the classic boot files with a classic grub configuration.> > > -- > One of the strokes of genius from McCarthy was making lists > the center of the language - kt > > > _______________________________________________ > 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
