<title>Dom0 Modifications for Resize/Migration Support</title>
|
|
<para>To get resize to work with XenServer (and XCP) you need to:</para>
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Establish a root trust between all hypervisor nodes of your
|
|
deployment:</para>
|
|
|
|
<para>You can do so by generating an ssh key-pair (with
|
|
<command>ssh-keygen</command>) and then ensuring
|
|
that each of your dom0's
|
|
<filename>authorized_keys</filename> file (located
|
|
in <filename>/root/.ssh/authorized_keys</filename>)
|
|
contains the public key fingerprint (located in
|
|
<filename>/root/.ssh/id_rsa.pub</filename>).</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Provide an <filename>/images</filename> mount point
|
|
to your hypervisor's dom0:</para>
|
|
|
|
<para>Dom0 space is a premium so creating a directory in
|
|
dom0 is kind of dangerous, and almost surely bound to
|
|
fail especially when resizing big servers. The least
|
|
you can do is to symlink <filename>/images</filename>
|
|
to your local storage SR. The instructions below work
|
|
for an English-based installation of XenServer (and
|
|
XCP) and in the case of ext3 based SR (with which the
|
|
resize functionality is known to work
|
|
correctly).</para>
