It works! I wonder why this didn't work: title Fedora (2.6.31-rc6-enming.teo) Serial Console root (hd0,0) kernel /xen.gz iommu=3D1 com1=3D115200,8n1 console=3Dcom1 module /vmlinuz-2.6.31-rc6-enming.teo ro root=3D/dev/mapper/vg_fedora11_host-lv_root selinux=3D0 console=3DttyS0,1= 15200 module /initrd-2.6.31-rc6-enming.teo.img And this worked: title pv_ops dom0-test (2.6.29-rc7-tip) with serial console root (hd0,0) kernel /xen-3.3.gz dom0_mem=3D1024M loglvl=3Dall guest_loglvl=3D= all com1=3D19200,8n1 console=3Dcom1 module /vmlinuz-2.6.29-rc7-tip ro root=3D/dev/vg00/lv01 console=3D= hvc0 earlyprintk=3Dxen module /initrd-2.6.29-rc7-tip.img Anyway, I still got a tty1 output! I thought that after using serial cons= ole, it is not supposed to output to a monitor anymore? As a result of this, I still can't hide the VGA card from dom 0 and pass = it through to the Windows Dom U.
