Hi, I'm hoping someone can help guide me to a fully working UML setup. On the host, I'm running the AMD64 port of Debian Sarge with a custom kernel built from the standard kernel.org 2.6.16.1 source with the SKAS3-v8.2 patch applied. uname -a gives:
Linux bedlam 2.6.16.1-jp5-skas3-v8.2 #1 SMP PREEMPT Fri Mar 31 12:34:36 BST 2006 x86_64 GNU/Linux The guest kernel is again built from the 2.6.16.1 source, in a seperate location (not /usr/src/linux) with the bb1 patch applied (but not the skas3 one). uname -a within the guest gives: Linux umlpcloc1 2.6.16.1-bb1 #1 Fri Mar 31 19:49:41 BST 2006 x86_64 GNU/Linux While the basic things work (i.e. I can boot into the UML, get networking going, use SSH etc) I am plagued with segfaults. I can't install firefox for example, it segfaults during the "firefox-bin -register" phase. I also get random segfaults when using "apt-get install". Xnest also works but frequently dies due to segfaults. When I boot the UML I notice it says I'm running in SKAS0 mode: ... 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 Linux version 2.6.16.1-bb1 ([EMAIL PROTECTED]) (gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13)) #1 Fri Mar 31 19:49:41 BST 2006 ... Does skas3 work with AMD64? Am I missing something fundamental here? I have a 32-bit chroot on the system, and I've tried using that to build a 32-bit (686) UML but again I had problems with segfaults - not necessarily in the same places. I'm ripping out my hair here and would welcome any advice you have to offer. If you need any more information just let me know, Cheers, John ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
