Category: None Group: None >Status: Closed >Resolution: Duplicate Priority: 5 Private: No Submitted By: Technologov (technologov) Assigned to: Nobody/Anonymous (nobody) Summary: Debian 4 fails to boot on KVM-AMD Initial Comment: Host: AMD Barcelona K10, F7/x64, KVM-62. Guest: Debian 4 (32-bit). Problem: When installing Debian 4 (32-bit) on KVM-AMD host, it installs "k7" kernel by default, and the resulting image is not bootable. It can be booted only with "-no-kvm". This problem can be avoided when installing on KVM-intel host, which uses "i686" kernel for Debian guests. This is because Debian's setup check for CPUID and setups the kernel, that best matches the current CPU. This kernel (i686) can be booted from kvm-intel or from kvm-amd without problems. Perhaps KVM-AMD doesn't emulate something K7 specific (3Dnow ?). I don't know what is the best solution to this problem, but I think using custom CPUID when installing Debian guests might do it. Any ideas? =================================================== (gdb) bt #0 0x0000003dd02c9117 in ioctl () from /lib64/libc.so.6 #1 0x000000000051bb29 in kvm_run (kvm=0x2a9b040, vcpu=0) at libkvm.c:850 #2 0x00000000004fda86 in kvm_cpu_exec (env=<value optimized out>) at /root/Linstall/kvm-62rc2/qemu/qemu-kvm.c:127 #3 0x00000000004fe5d5 in kvm_main_loop_cpu (env=0x2b82bb0) at /root/Linstall/kvm-62rc2/qemu/qemu-kvm.c:307 #4 0x00000000004110fd in main (argc=44675488, argv=<value optimized out>) at /root/Linstall/kvm-62rc2/qemu/vl.c:7862 =================================================== kvm statistics efer_reload 0 0 exits 11387804 324872 fpu_reload 1340894 296 halt_exits 0 0 halt_wakeup 0 0 host_state_reload 1340931 295 hypercalls 0 0 insn_emulation 10053389 323534 insn_emulation_fail 10009814 323534 invlpg 0 0 io_exits 1334757 1004 irq_exits 0 0 irq_window 0 0 largepages 0 0 mmio_exits 27231 0 mmu_cache_miss 20 0 mmu_flooded 0 0 mmu_pde_zapped 0 0 mmu_pte_updated 0 0 mmu_pte_write 0 0 mmu_recycled 0 0 -Alexey, 3.3.2008. ---------------------------------------------------------------------- >Comment By: Jes Sorensen (jessorensen) Date: 2011-03-03 16:06 Message: Joerg moved this to https://bugzilla.kernel.org/show_bug.cgi?id=30402 ---------------------------------------------------------------------- Comment By: Joerg Roedel (jroedel) Date: 2008-03-03 17:54 Message: Logged In: YES user_id=2019182 Originator: NO I was able to reproduce this problem. The instruction emulater lacks support for mmx memory instructions. Needs to be fixed. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1906272&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
