Re: [Libguestfs] appliance VM won't start, can't find /init, but /init is in the image.



OK.  So now I am trying with a 2.6.38 kernel.  Surprising result: some confusion about ext2 root filesystem.  I can confirm the /var/tmp/.guestfs has a root file that is a valid ext2 file system.  

libguestfs: new guestfs handle 0x22df410

You could compile it from source, but it'd be easier to just take a
compiled binary from any later Ubuntu (11.04 seems like the best bet
since it's the one we use).  Don't forget you need the modules
directory as well as vmlinuz.


Looks like this is moot.  Turns out my kernel team has a test kernel (2.6.38, I feel like I'm in the 23rd century) and I'm getting my workstation converted to that.
