Hello,
I successfuly run Centos 5.1 domU in Centos 5.1 dom0. But I still have some minor issues/errors/warnings while booting I'd like to fix and here are my questions:
- How to disable loading usb host controler module:
[...from dmesg... ] Loading uhci-hcd.ko module USB Universal Host Controller Interface driver v3.0 insmod: error inserting '/lib/uhci-hcd.ko': -1 No such device Loading ohci-hcd.ko module insmod: error inserting '/lib/ohci-hcd.ko': -1 No such device Loading ehci-hcd.ko module mount: could not find filesystem '/proc/bus/usb' [...] I have extra parameters being passed to kernel in grub: kernel /boot/vmlinuz-2.6.18-53.1.14.el5xen ro root=LABEL=/ console=xvc0 nousb nopcmcia parport=0 but it seems kernel ignores it in domU (works in dom0)
- How to disable loading floppy detection/support

- How to setup xm console correctly? While system boots I see:
Remounting root filesystem in read-write mode: [ OK ] Mounting local filesystems: [ OK ] Enabling local filesystem quotas: [ OK ] Enabling /etc/fstab swaps: [ OK ] INIT: Entering runlevel: 3 Entering non-interactive startup
with no colors. How to make it real console-like, with colors:
Remounting root filesystem in read-write mode: [ OK ] Mounting local filesystems: [ OK ] Enabling local filesystem quotas: [ OK ] Enabling /etc/fstab swaps: [ OK ]
I use this config for my domUs:
name = "CentOS" memory = "1024" extra = "TERM=vt100 xencons=xvc console=xvc0 console=tty1 video=xenfb" disk = [ 'phy:CentOS/CentOS,xvda,w' ] vif = [ 'bridge=xenbr0' ] vfb = [ 'type=vnc' ] bootloader = "/usr/bin/pygrub" vcpus = 1 on_reboot = 'restart' on_crash = 'restart'
If you want the xen console as the primary I believe you need to reverse the consoles in the 'extra' setting, if you want color then set TERM=linux.
My config also sets up a graphic framebuffer in domU accessible via vnc.
