 The network controller should be configured as PCnet-PCI II or PCNet-FAST III

+Note: If your Hurd image freezes on startup with "start ext2fs: ext2fs: device:hd0s1: No such device or address", then you may need to manually edit the hard disk controller to be "IDE", because VirtualBox defaults to "SATA" which does not work. Go in to the "Storage" tab and check whether there is an entry for "Controller: SATA". If the SATA entry exists and the Hurd disk image is attached to it, delete the SATA controller and then add a new hard disk under "Controller: IDE". Restart the virtual machine. The hard disk should now be accessible via an IDE interface and Hurd should start successfully and reach the login prompt. (This is the case on VirtualBox 4.3.28 on Mac OS.)

-    <tschwinge> I should still be able to access the data from Barry's zenhost
-      (including all the VMs it hosted), so I should be able to replicate that
-      quite easily.
-    <braunr> do you think it could be hosted on darnassus, or would you like a
-      separate vm ?
     <tschwinge> The repository for people to push to and pull from (used to be
       on flubber) would be on darnassus now.
-    <tschwinge> About the web server, hmm.
-    <tschwinge> It's basically a security concern.
-    <tschwinge> And it might get hammered by bots from time to time.
-    <braunr> it won't need much resources i suppose
-    <tschwinge> No.  The web server (snubber) was running with 242 MiB of RAM,
-      and had uptimes of several weeks typically.
-    <braunr> tschwinge: otherwise, could it use the web server running on the
-      host ?
-    <tschwinge> The host being darnassus?
-    <braunr> no
-    <braunr> shattrath, the linux system
-    <tschwinge> Ah.
-    <tschwinge> Sure.
-    <tschwinge> There is no requirement this to be a Hurd system -- was just
-      nice to show to people.
-    <braunr> i think it is too
-    <braunr> what's the problem with darnassus ?
-    <braunr> yçou mentioned security
-    <tschwinge> The web server being a public-facing component which might be
-      broken into.
-    <braunr> how ?
-    <braunr> it's so much easier to just ask for an account .. :)
-    <tschwinge> Web server bugs, CGI script bugs, etc.
-    <tschwinge> Sure.
-    <tschwinge> I just wanted to make you aware of it.  :-)
-    <braunr> oh don't worry
-    <braunr> ok so darnassus it is
-    <pinotree> was it running apache? maybe, if other (lighter?) web servers
-      are tested to work on hurd, they could be used
-    <tschwinge> pinotree: Yes, and yes.
-    <braunr> doesn't ikiwiki need php ?
-    <tschwinge> Only requirement (I think) is abaility to run CGI scripts.
-    <tschwinge> braunr: No.  It's written in perl.
-    <braunr> ok
-    <braunr> i still think i'll use apache
-    <braunr> it's really not that heavy
-    <braunr> lighter servers matter when the number of concurrent clients get
-      very high
-    <tschwinge> Then I'll figure out how exactly the setup was between flubber
-      and snubber.
-    <braunr> ok
-    <braunr> it's good to finally get that going :)
