Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: kvmuser2010 (kvmuser2010) Assigned to: Nobody/Anonymous (nobody) Summary: qemu_x86-64 cores on linux Initial Comment: Sorry. I couldn't find any mailing list etc for kvm. so posting it here I am trying to get KVM/qemu running on linux. I compiled 2.6.27.10 by enabling "KVM", "KVM for intel" options at configure time. My box is running with this KVM enabled inside kernel. I also built qemu-kvm-0.12.2 using above kernel headers etc. I enabled virtualization in BIOS. I didn't try to install any guest from CD etc. I made a hard disk image, installed grub on it, copied kernel, initrd onto it. Now when I try to create Vm as below, it crashes with following backtrace. What could be going wrong? Also when I try to say "-m 256" malloc (or posix_memalign) fails with ENOMEM. So right now "-m 128", which is default, works. Why is that? I have 4G RAM in my setup and my native linux is using less than 1G. Is there some rlimits for qemu that I need to raise? Sounds like I'm doing some basic stuff wrong. I'm using bios, vapic, pxe-rtl bin straight from the qemu-kvm dir. If I don't do '-nographic' its running into some malloc failure inside some vga routine. I pasted that backtrace too below. Appreciate your help. thanks qemu-system-x86_64 -hda /dev/shm/vmhd.img -bios ./bios.bin --option-rom ./vapic.bin -curses -nographic -vga none -option-rom ./pxe-rtl8139.bin #0 0x414875a6 in raise () from /lib/libc.so.6 (gdb) bt #0 0x414875a6 in raise () from /lib/libc.so.6 #1 0x4148ad18 in abort () from /lib/libc.so.6 #2 0x080b4cb3 in die2 (err=<value optimized out>, what=0x81f2662 "pthread_create") at posix-aio-compat.c:80 #3 0x080b5682 in thread_create (arg=<value optimized out>, start_routine=<value optimized out>, attr=<value optimized out>, thread=<value optimized out>) at posix-aio-compat.c:118 #4 spawn_thread () at posix-aio-compat.c:379 #5 qemu_paio_submit (aiocb=0x846b550) at posix-aio-compat.c:390 #6 0x080b57cb in paio_submit (bs=0x843c008, fd=5, sector_num=0, qiov=0x84cefb8, nb_sectors=512, cb=0x81cb950 <dma_bdrv_cb>, opaque=0x84cef80, type=1) at posix-aio-compat.c:584 #7 0x080cc7b8 in raw_aio_submit (type=<value optimized out>, opaque=<value optimized out>, cb=<value optimized out>, nb_sectors=<value optimized out>, qiov=<value optimized out>, sector_num=<value optimized out>, bs=<value optimized out>) at block/raw-posix.c:562 #8 raw_aio_readv (bs=0x843c008, sector_num=0, qiov=0x84cefb8, nb_sectors=1, cb=0x81cb950 <dma_bdrv_cb>, opaque=0x84cef80) at block/raw-posix.c:570 #9 0x080b0593 in bdrv_aio_readv (bs=0x843c008, sector_num=0, qiov=0x84cefb8, nb_sectors=1, cb=0x81cb950 <dma_bdrv_cb>, opaque=0x84cef80) at block.c:1548 #10 0x081cbb26 in dma_bdrv_cb (opaque=0x84cef80, ret=0) at /ws/pkoya-sjc/temp/qemu-kvm-0.12.2/dma-helpers.c:123 #11 0x081cbcde in dma_bdrv_io (bs=0x843c008, sg=0x846861c, sector_num=0, cb=0x8074320 <ide_read_dma_cb>, opaque=0x8468f1c, is_write=0) at /ws/pkoya-sjc/temp/qemu-kvm-0.12.2/dma-helpers.c:167 #12 0x0807441b in ide_read_dma_cb (opaque=0x8468f1c, ret=0) at /ws/pkoya-sjc/temp/qemu-kvm-0.12.2/hw/ide/core.c:597 #13 0x080760ec in bmdma_cmd_writeb (opaque=0x8468f1c, addr=49152, val=9) at /ws/pkoya-sjc/temp/qemu-kvm-0.12.2/hw/ide/pci.c:51 #14 0x080d9d5f in ioport_write (data=<value optimized out>, address=<value optimized out>, index=<value optimized out>) at ioport.c:80 #15 cpu_outb (addr=6587, val=<value optimized out>) at ioport.c:198 #16 0xb60a3bc9 in ??
