Hi, I'm trying to run a x86_64 host system with a 32bit and/or a 64bit guest system.
Whilst applying the uml kernel patch -bb1 for the 2.6.18 kernel, I get the following messages: -> patching file arch/um/Makefile-x86_64 Reversed (or previously applied) patch detected! Assume -R? [n] Apply anyway? [n] Skipping patch. 1 out of 1 hunk ignored -- saving rejects to file arch/um/Makefile-x86_64.rej <- -> patching file arch/um/include/sysdep-i386/kernel-offsets.h Reversed (or previously applied) patch detected!

[n] Skipping patch. 1 out of 1 hunk ignored -- saving rejects to file arch/um/os-Linux/tls.c.rej <- After all that, the kernel compiles well and runs - but only in skas0 mode with the following error on startup: -> [EMAIL PROTECTED]:~# /home/test/vmlinux-2.6.18.1-64 ubd0=/home/test/Debian-3.1-AMD64-root_fs mem=64M con0=fd:0,fd:1 Checking that ptrace can change system call numbers...OK Checking syscall emulation patch for ptrace...missing Checking for tmpfs mount on /dev/shm...OK Checking PROT_EXEC mmap in /dev/shm/...OK Checking for the skas3 patch in the host: - /proc/mm...found - PTRACE_FAULTINFO...not found - PTRACE_LDT...found UML running in SKAS0 mode <- I tried the same with the kernels on Paolo's website, but I did not succeed in starting a 64bit instance on a 64bit host in skas3 mode. My 32bit guest kernels won't start on the 64bit host, either. Could someone clarify the status of UML and SKAS3 on 64 bit hosts? - Is it possible to run 32 bit guests on 64 bit hosts - in skas3? in skas0? how? - Is it possible to run 64 bit guests on 64 bit hosts - in skas3? - If a 64bit guest won't run in skas3, how much of a performance penalty do you expect in running skas0 with a noptracefaultinfo set? I tried to search the list for this information, but there was no sufficient answer to me, sorry if this request is redundant in any kind.
