Hello All,
I am new to the Xen scene but an experienced Linux user. Today I
downloaded and installed the tarballed version of Xen 3.0 on my Dell
PowerEdge 2850 server (1x3.4GHz x86_64 proc, 4GB RAM, 700GB storage). I
successfully made my initrd image from the 2.6.12.6-xen (not xen0) libs
and booted up. However, now that I have modified the grub.conf file and
specified the dom0_mem for the master domain and rebooted, Xwindows
hangs when it (Xwindows) tries to start up. If I leave the dom0_mem
setting out of my grub.conf file, everything works fine, but now I can't
allocate memory to my slave OSs. Any thoughts. FYI; I did see on the
FAQ that this could be caused by agpart, but it was refering to the 2.x
series of Xen.
Also, after approx. 20 mins. after running the Xen0 master kernel,
the system logger says that it is disabling IRQ 16. Any thoughts as to
why? Below I have both my grub.conf file and the entries in my
/var/log/messages file (regarding the IRQ16 disabling).
Thanks in advance.
Mike Lee
