			<content:encoded><![CDATA[<p>So a buddy of mine about a week ago decides to put together a machine whose software setup is similar to the machine which runs DotBlag here.  <a href="http://sun.com/solaris">Solaris</a> or <a href="http://opensolaris.org">OpenSolaris</a>, running <a href="http://debian.org">Debian</a> inside of a Paravirtualized Machine under <a href="http://wiki.xensource.com">Xen</a> (xVM in Solaris).</p>
<p>This process sucks a little bit because unlike everyone else Debian still doesn&#8217;t support PVM inside of their installer.  So you have to fire up a full HVM environment and use debootstrap, OR, convert that (HVM) environment to a PVM.</p>
<p>Everything was fine getting the initial HVM bootstrap env up, but nothing he did would get pygrub to fire up the kernels, it kept complaining (when run interactively) that it could not find the kernel.</p>
<pre># pygrub /dev/zvol/dsk/p0/zvol2
Traceback (most recent call last):
  File "./pygrub", line 658, in ?
    chosencfg = run_grub(file, entry, fs)
  File "./pygrub", line 509, in run_grub
    g = Grub(file, fs)
  File "./pygrub", line 198, in __init__
    self.read_config(file, fs)
  File "./pygrub", line 388, in read_config
    raise RuntimeError, "couldn't find bootloader config file in the image provided."
RuntimeError: couldn't find bootloader config file in the image provided.</pre>
<p>This was to say the least, VERY irritating.  And we couldn&#8217;t figure out why.  We tried messing with the partition tables, the menu.lst, everything.  Until I remembered a problem with mke2fs -t ext2 NOT producing 2.4.x compatible ext2 filesystems and began to wonder if that is what happened here.  Sure enough, running mke2fs from Debian 4 and not Debian 5 produced a working system.  Solaris&#8217; pygrub is completely useless in providing a good error, only providing the traceback above.</p>
<p>Hopefully this will help some poor soul trying to get Debian 5 inside a PVM running on Solaris or OpenSolaris.</p>

			<content:encoded><![CDATA[<p>OK so if you try to pronounce it incorrectly people might think you have a cold.  The good news is though that <a href="http://rfc-editor.org/cgi-bin/rfcdoctype.pl?loc=RFC&amp;letsgo=4366&amp;type=ftp&amp;file_format=txt">Server Name Identification</a> AKA <a href="http://rfc-editor.org/cgi-bin/rfcdoctype.pl?loc=RFC&amp;letsgo=4366&amp;type=ftp&amp;file_format=txt">TLS-SNI</a> will <a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461917">likely be making it</a> into <a href="http://www.us.debian.org/releases/lenny/">Debian Lenny</a>.  It&#8217;s already in <a href="https://issues.apache.org/bugzilla/show_bug.cgi?id=34607">Apache 2.2.x upstream</a> but there&#8217;s no release with it quite yet.  </p>
<p>Now we can do SSL Names Based VHosts&#8230;.sorta.  Only <a href="http://www.microsoft.com/windows/ie/default.mspx">IE7 on Vista</a>, <a href="http://www.opera.com/products/desktop/">Opera 8</a>, and <a href="http://www.mozilla.com/firefox/">Firefox 2+</a> support it (<a href="https://sni.velox.ch/">sni.velox.ch is a test site</a> FYI).  C&#8217;mon <a href="http://apple.com/safari">Apple</a>!  Get with it.  And Microsoft?  WTF is up with Vista only support.  </p>
<p>Soon.  Soon.  And this becomes more and more important as we run out of IPv4 addresses.  In fact for a LOT of places, it&#8217;s the primary use of IPv4 address space, including here!</p>
