[Xen-users] Install CentOS as Dom-U

[Daniel Lam <daniel@xxxxxxxxxxxxxxxx>]

Hi there,

I'm getting confused trying to install CentOS as Dom-U.

I'm trying to follow instructions here, 

http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU

which is to

1. Download "domU installation initrd image and kernel" from CentOS mirrors site

2. Create a Domain Config File which kernel and ramdisk parameters point to the 

    files in step 1

3. Install the domain U by running "xm create <domain config file>"

So far so good. However in this domain U installation process, it asks about

package source location and the instructions in wiki suggested supplying the 

normal CentOS download location. I'm confused - this is as if I'm installing 

a "real" CentOS, like installing dom0.

My questions:

- If I proceed, am I installing as a para-virtualized CentOS (which is what I want),

  or am I installing as a full-virtualized CentOS (which is what it looks like to me at the moment)?

- When I was previously using Debian as domain-0, xen-tools set up the guest domain

  configuration file in such a way that its kernel parameter is specified "/boot/vmlinuz-2.6.26-2-xen-686".

  However in the CentOS wiki, it's suggesting not to specify it after install.

  I don't get it - Should kernel be specified? And if it is, does it mean the kernel of

  domain-U is actually in domain 0?

- With Debian I could use xen-tools. Are there similar tools with CentOS?

  Some pointed virt-install but that appears to not have CentOS as one

  of the OS options.

Cheers,

Daniel
