Hi, <br>
<br>
One of my servers in a IDC in another country mysteriously went down
this morning, and when I contacted the IDC, I was told that XEN doesn&#39;t
boot up, as follows:<br>
<br>
[QUOTE]<br>
This is error message on the screen &quot; Error 19: Linux Kernel must be loaded before initrd&quot;<br>

<br>

Server is currently up with 2nd kernel.<br>

<br>

Please check the grub.conf.<br clear="all">[/QUOTE]<br>
<br>
Looking at grub.conf, I see the following:<br>
<br>
#boot=/dev/hda<br>
default=0<br>
timeout=5<br>
splashimage=(hd0,0)/grub/splash.xpm.gz<br>
hiddenmenu<br>
title CentOS (2.6.18-128.1.10.el5xen)<br>
        root (hd0,0)<br>
        kernel /xen.gz-2.6.18-128.1.10.el5 ro root=/dev/VolGroup00/LogVol01 ide0=noprobe ide1=noprobe<br>
        initrd /initrd-2.6.18-128.1.10.el5.img<br>
title CentOS (2.6.18-128.1.10.el5)<br>
        root (hd0,0)<br>
        kernel /vmlinuz-2.6.18-128.1.10.el5 ro root=/dev/VolGroup00/LogVol01 ide0=noprobe ide1=noprobe<br>
        initrd /initrd-2.6.18-128.1.10.el5.img<br>
title CentOS (2.6.18-128.el5)<br>
        root (hd0,0)<br>
        kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol01<br>
ide0=noprobe ide1=noprobe<br>
        initrd /initrd-2.6.18-128.el5.img<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
Then on another server, I see the following in grub.conf:<br>
#boot=/dev/sda<br>
default=0<br>
timeout=5<br>
splashimage=(hd0,0)/grub/splash.xpm.gz<br>
hiddenmenu<br>
<br>
title CentOS (2.6.18-8.1.15.el5xen)<br>
        root (hd0,0)<br>
        kernel /xen.gz-2.6.18-8.1.15.el5<br>
module /vmlinuz-2.6.18-8.1.15.el5xen ro root=/dev/VolGroup00/root<br>
module /initrd-2.6.18-8.1.15.el5xen.img<br>
<br>
title CentOS (2.6.18-8.1.15.el5)<br>
        root (hd0,0)<br>
        kernel /vmlinuz-2.6.18-8.1.15.el5 ro root=/dev/VolGroup00/root<br>
        initrd /initrd-2.6.18-8.1.15.el5.img<br>
<br>
title CentOS (2.6.18-8.el5)<br>
        root (hd0,0)<br>
        kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/root<br>
        initrd /initrd-2.6.18-8.el5.img<br>
<br>
<br>
<br>
<br>
<br>
<br>
On both kernels, I can see that initrd is loaded 2nd, as it should. So
the error doesn&#39;t make sense. The BIG problem is that the server is on
another continent, and their support is totally useless. I have actiall
ordered a new server, from another IDC and got it last night,  but need
XEN to work on this server in order to move the domU&#39;s across. <br>
<br>
Can anyone see anyting wrong with this? Google has revelaed the
obvious, that the initrd is incorrectly loaded, but according to the
grub.conf that I have, it should be loading properly.<br clear="all"><br>-- <br>Kind Regards<br>Rudi Ahlers<br>CEO, SoftDux Hosting<br>Web: <a href="http://www.SoftDux.com">http://www.SoftDux.com</a><br>Office: 087 805 9573<br>
