Re: [Fedora-xen] fc5 kernel-xen0 w/ pae

[Jason Tower]

that's what i tried already (reread my original post).  but xend doesn't
start properly when booting kernel-xen (it starts fine with kernel-xen0).
thanks for answering my question, the next problem is to figure out why xend
isn't happy with that particular kernel.

unfortunately circumstances beyond my control have forced me to put this box
in production my monday am so i can't troubleshoot things at this time.
hopefully i can scrounge up a similar box w/ 6gb ram so i can work this out.

Can you post your log from XEN - xen dmesg and the /var/log/xen* files?

fc5 kernel-xen0 w/ pae

[Jason Tower]

i will as soon as i cobble together another test box with that much ram,
hopefully later this week.  this particular box goes into production on
monday so i pulled two of the ram sticks out and am just using 4gb with the
xen0 kernel.  thanks for the help - jason

fc5 kernel-xen0 w/ pae

[Jason Tower]

i tracked it down to this:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=202182

i did manage to work around it by adding the modprobe lines in the xend init
script (see the bz link above), plus i had to build a new initrd with the
xenblk module in order to boot my ubuntu domU:

  mkinitrd --preload=xenblk /boot/initrd.img `uname -r`

now it seems to be working fine, i have access to 6gb ram and everything
starts as it should.
