So I compile new xen and xenolinux images with the matching tools and I have
some troubles. When I boot the first time with new kernels, the boot frozen
after enabling the Real Time Clock Driver. So I removed it from the kernel and
everything went fine. I don't know if this driver is a problem. I will make a
new try with "Enhanced Real Time Clock Support" enable in the kernel...
Another problem occures when I try to start a new domain. I receive a kernel
panic during the boot. I use the following /etc/xenctl.xml file:
--------------------------------------------------
xenohost2:~# cat /etc/xenctl.xml
<?xml version="1.0"?>
<domctl_defaults>
<domain_name>XenoLinuxDeb</domain_name>
<domain_size_kb>98304</domain_size_kb>
<domain_image>/boot/xenolinux11.gz</domain_image>
<domain_vifs>1</domain_vifs>
<root_device>/dev/hda5</root_device>
<root_args>rw</root_args>
<args>4 DOMID=+</args>
<nw_ip>169.254.1.0+</nw_ip>
<nw_gw>169.254.1.0</nw_gw>
<nw_mask>255.255.0.0</nw_mask>
<nw_nfs_server>169.254.1.0</nw_nfs_server>
<max_domain_number>1000</max_domain_number>
<xi_tools_dir>/usr/local/bin/</xi_tools_dir>
</domctl_defaults>
--------------------------------------------------------
And when I use the command "xenctl script -f/etc/xen-mynewdom" I have the
following output:
--------------------------------------------------------

I don't know when the partition is checked there is an error because it works
fine during the boot of domain_0 as I can see with dmesg output:

--------------------------------------------------------
So I will try to found what is going wrong. I don't know if the new domain
access to hardware via domain_0 or if it can access through the hypervisor
because here it seems that my new domain is not allow to access /dev/hda...
