Hi everybody, Is it possible to install PV DomainU from a CD-ROM? Say Ubuntu or CentOS? Bill _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I am using the stock Xen that comes with CentOS 5.5, and I have installed CentOS 5, CentOS 4, OpenBSD, and Windows XP as DomU''s (BSD and Windows were not PV). But I have never been able to get Fedora to install, either para or full virtualization. It always hangs during the kernel boot from the install CD. So the answer is YMMV (it may depend on what OS your Dom0 is, what version of Xen you are running, and what OS you are trying to install as a DomU). --Greg _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Then, convert it to a PV by installing a xen kernel, modifying /etc/inittab, securetty, and fstab, and telling the kernel that root is /dev/xvda versus /dev/hda, then modifying the domU''s config file to use pygrub. I''ve done this sucessfully for Ubuntu, Debian, and OpenSuse. I would assume CentOS will have a similar install to OpenSuse.

I''ve installed RHEL from cd, and that is similar enough to fedora. Have you tried an older version of fedora?

The oldest version I tried was F11, and I''ve also tried F12 and F13 after they were released with the same results: it hangs on the install when booting the kernel. I am aware that there is a place where I can download images for $10 that are reported to work (I''ve got the URL someplace), but I did this more as a test, to see what worked and what didn''t (it is still on my list to try Ubuntu Lucid). I suppose that installing an older version of Fedora would be a valid test from which something could be learned; how old would I have to go?>From things I''ve read, it seems like the real problem might be the newkernels that Fedora uses, and I might be able to get it to work by mounting and modifying the ISO and putting in an older kernel. That might cause other unanticipated problems of course, and that too would be illegal under our security policy unless the kernel version I put in could be supported outside of the Fedora update mechanism, but something could be learned from this too. I would think this would be a kernel bug, but I''m guessing that as long as it works under KVM, which is where Red Hat seems to be heading now, that they won''t consider it a bug. I have tried KVM and it works in some circumstances, but it isn''t nearly as robust as Xen, at least not yet, so I want to use Xen on the production servers. --Greg _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
