Hi, I've recently upgraded my UML setup from a 2.6.8+skas3 host kernel to a 2.6.18+skas on debian etch. I've also upgraded to using the nagafix kernel32-2.6.24.3 kernel to run my guest instances in.
I uses to be able to specify mem=3072M to the guest instance, but when I try this now I see : [EMAIL PROTECTED]:~/umltest$ /usr/bin/kernel32-2.6.24.3 udb0=./root_fs mem=3072M Core dump limits : soft - 0 hard - NONE 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 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...found - PTRACE_LDT...found UML running in SKAS3 mode CONFIG_HIGHMEM not enabled - physical memory shrunk to 3045064704 bytes Segmentation fault If I boot with something like mem=2800M it boots ok. I have a tmpfs partion defined on the host : tmpfs 4.0G 1.3G 2.8G 31% /dev/shm (which is empty when no guest is running). I have the following set in my host kernel : CONFIG_HIGHMEM4G=y CONFIG_PAGE_OFFSET=0xC0000000 CONFIG_HIGHMEM=y CONFIG_PROC_MM=y Anybody have any ideas what might be setting this limit, as I'd expect to be able to specify up to mem=4096M Thanks, Rob ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
