In kvm-10, the system hangs during boot. One of the last things I can see is that a shell process dies with a SIGSEGV. Then the load rises to 100% (sys) on the host and stays there until I kill qemu (yes I've waited several minutes). - opensolaris displays a "Time of Day clock error" during boot, claiming the clock has jumped by 0x5 (no unit given, I suppose that means seconds). Everything else seems to work. - qemu-puppy-2.13-1 sometimes works and sometimes hangs somewhere inside the initial ramdisk. The exact place seems to differ, but usually it happens while the kernel modules are loaded. Again, host load rises to 100%. An older version (2.01-3) still works fine. kvm-9 works, too. (Core Duo T2400, 32-bit SMP host, 32-bit guest, Linux 2.6.19 + kvm trunk revision 4290) Any idea what to look for? The SIGSEGV on netbsd makes me suspect that there's a problem with the page tables, but I couldn't narrow down the cause yet. -- Michael "Tired" Riepe X-Tired: Each morning I get up I die a little ------------------------------------------------------------------------- Take Surveys.
