Re: [Xen-users] Xen :Am not able to create a XenU Domain forFedoraCore 4

[Daniel Lacroix <dlacroix@xxxxxxxxxx>]

I have a working solution now. I try the Xen tools available with the
Fedora Core 4 without any update:

kernel-xen0-2.6.11-1.1369_FC4.i686.rpm
kernel-xenU-2.6.11-1.1369_FC4.i686.rpm
xen-2-20050522.i386.rpm

and now it is working even with memory like 768 MB for the VM. If it
help, here is my grub config:

title Fedora Core (2.6.11-1.1369_FC4xen0)
        root (hd0,0)
        kernel /boot/xen.gz dom0_mem=1572864
        module /boot/vmlinuz-2.6.11-1.1369_FC4xen0 ro root=LABEL=/
        module /boot/initrd-2.6.11-1.1369_FC4xen0.img

I also disabled TLS by doing:
mv /lib/tls /lib/tls.disabled

this was no the problem but I have done it.
