I'm trying to get a UML virtual machine running on a ReadyNAS Ultra 4. I was trying VirtualBox for the VM, but can't seem to get that running either.
Looking at the UML homepage http://user-mode-linux.sourceforge.net/ they say it's as simple to get going as download the kernel, download a filesystem, and simply run "./kernel ubda=filesystem" Anyone here with UML experience? Actually it may not just be a UML issue, but more my understanding of TTY/PTY/PTS terminals/consoles etc. I'll continue... The RNAS box is a x86_64 processor. The kernel I downloaded was kernel32-2.6.39.2 for 32 bit i386, and the filesystem was Ubuntu-LucidLynx-i386-root_fs. I did also download 64 bit kernel and filesystem, but the FS one was for AMD64. Got them from http://uml.devloop.org.uk/index.html and http://fs.devloop.org.uk/ Below is an extract of the output, I can provide full if that'll help. I'm shelling into the NAS via ssh and then opening a screen session. "tty" in one of the screen windows is /dev/pts/1 etc. After that last line nothing else is displayed, and I have to killall the process I'm not sure where to go from here. Searching around google the only time similar question has come up, it's unanswered. Any suggestions? # ./kernel32-2.6.39.2 ubda=./Ubuntu-LucidLynx-i386-root_fs Locating the bottom of the address space ... 0x0 Locating the top of the address space ...
