Hello, maybe I'm stupid but I find no way to
have the kernel in Dom0 instead of DomU for Centos 5.
Here is what I did:
Regular Centos 5 Dom0 install, then creating a LVM group (vms) and
install DomU with virt-install works perfectly:
virt-install --p --location=http://mirrors.kernel.org/centos/5/os/i386
--file=/dev/vms/centos5_data --name=centos5 --ram=512 --nographics
I get a working domU but the config file has no kernel or ramdisk
parameter and the kernel seems to be inside DomU
I created my own cfg then, using this parameter:
kernel = '/boot/vmlinuz'
ramdisk = '/boot/initrd.img'
root = '/dev/xvda ro'
name = "centos"
memory = "512"
disk = [ 'phy:/dev/vms/centos_data,xvda,w',
'phy:/dev/vms/centos_swap,xvdb,w',]
vif = [ 'mac=00:64:18:20:52:07, bridge=xenbr0', ]
vcpus = 1
on_reboot = 'restart'
on_crash = 'restart'
For vmlinuz I tried a copy of Dom0's kernel, the kernel copied from
inside the DomU as well as the downloaded kernel file from here:
http://mirrors.kernel.org/centos/5/os/i386/images/xen/
For initrd.img I tried a copy of
Dom0's ramdisk, the ramdisk copied from inside the DomU as well as the
downloaded ramdisk file from kernel.org.
I even tried building a ramdisk with:
/sbin/mkinitrd /boot/initrd.img 2.6.18-8.el5xen --with=netfront
--with=blkfront --with=sd_mod --with=scsi_mod
Nothing helps, the result is always:
mount: could not find filesystem '/dev/root'
then
switchroot: mount failed: No such file or directory
...well not always, if I use the ramdisk downloaded from kernel.org, I
get a installation procedure (asking for language, skip media check and
so on).
What have I done wrong?
Thank you very much for any help here!
