the two patches i needed to build 2.6.17-rc1 on a fresh FC5 system are attached. i am now running it with filesystem: http://uml.nagafix.co.uk/FedoraCore5 and have not modified the FC5 host kernel or filesystem in any way. it doesn't eat the umid= arg (no uml_utilities on the host?) and there is an initcall failure related to tls - but i get a prompt and that's pretty cool thank you all very much. linux-2.6.17-rc1 umid=happy ubd0=cow1,root_fs.fc-5 Checking that ptrace can change system call numbers...OK Checking syscall emulation patch for ptrace...OK Checking advanced syscall emulation patch for ptrace...OK Checking PROT_EXEC mmap in /tmp...OK Checking for the skas3 patch in the host: - /proc/mm...not found - PTRACE_FAULTINFO...not found - PTRACE_LDT...not found UML running in SKAS0 mode Adding 9007104 bytes to physical memory to account for exec-shield gap <...snip...> Checking for host processor cmov support...Yes Checking for host processor xmm support...No Checking that host ptys support output SIGIO...Yes Checking that host ptys support SIGIO on close...No, enabling workaround /usr/include/linux/aio_abi.h not present during build 2.6 host AIO support not used - falling back to I/O thread not_dead_yet : couldn't open pid file '/home/rtrsvcs/dbahi/.uml/happy/pid', err = 1 Failed to create 'happy' - err = -17 Failed to initialize umid "happy", trying with a random umid NET: Registered protocol family 16 Checking host MADV_REMOVE support...MADV_REMOVE failed, err = -22 Can't release memory to the host - memory hotplug won't be supported mconsole (version 2) initialized on /home/rtrsvcs/dbahi/.uml/vyvh4O/mconsole ubd: Synchronous mode Host TLS support detected Detected host type: i386 initcall at 0x0804cc9e: __setup_host_supports_tls+0x0/0x64(): returned with error code 1
