I tested this on the same system and I see something different. Trying to run a 6.8 guest, my 6.8 L1 crashes with the following trace (in L1): -----------[ cut here ]------------ kernel BUG at arch/x86/kvm/../../../virt/kvm/kvm_main.c:3167! invalid opcode: 0000 [#1] SMP last sysfs file: /sys/module/kvm_amd/initstate CPU 0 Modules linked in: ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat xt_CHECKSUM iptable_mangle bridge stp llc autofs4 ipt_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 iptable_filter ip_tables ip6t_REJECT nf_co] Pid: 2452, comm: qemu-kvm Not tainted 2.6.32-696.el6.x86_64 #1 Red Hat KVM RIP: 0010:[<ffffffffa018d3c9>] [<ffffffffa018d3c9>] kvm_spurious_fault+0x9/0x10 [kvm] RSP: 0018:ffff880079eebc20 EFLAGS: 00010046 RAX: ffff880078b10000 RBX: ffff88007d3a8038 RCX: 0000000002200000 RDX: 0000000000000000 RSI: ffff880079eebc54 RDI: 0000000002200000 RBP: ffff880079eebc20 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000001 R12: ffff88007d3a8098 R13: 0000000000000000 R14: 0000000000000000 R15: ffff880037083520 FS: 00007fe15316b700(0000) GS:ffff880002200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fe15d2c7000 CR3: 0000000036d2f000 CR4: 00000000000407f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process qemu-kvm (pid: 2452, threadinfo ffff880079ee8000, task ffff880037083520) Stack: ffff880079eebc88 ffffffffa0201849 ffffffffa01fdec6 000000000000bc88 <d> ffff88007d3a8038 ffff880079eebc68 0000000000000000 ffff880079eebc88 <d> ffff88007d3a8038 ffff88007d3a8098 0000000000000000 0000000000000000 Call Trace: [<ffffffffa0201849>] svm_hardware_unsetup+0xcd/0x172 [kvm_amd] [<ffffffffa01fdec6>] ? svm_vcpu_run+0x156/0x520 [kvm_amd] [<ffffffffa01a88fa>] kvm_arch_vcpu_ioctl_run+0x40a/0x1060 [kvm] [<ffffffffa018f034>] kvm_vcpu_ioctl+0x434/0x580 [kvm] [<ffffffff8109402d>] ? __sigqueue_free+0x3d/0x50 [<ffffffff81097702>] ? __dequeue_signal+0x102/0x200 [<ffffffff811af602>] vfs_ioctl+0x22/0xa0 [<ffffffff811afaca>] do_vfs_ioctl+0x3aa/0x580 [<ffffffff811afd21>] sys_ioctl+0x81/0xa0 [<ffffffff810ee3ce>] ? __audit_syscall_exit+0x25e/0x290 [<ffffffff8100b0d2>] system_call_fastpath+0x16/0x1b Code: 00 00 55 48 89 e5 0f 1f 44 00 00 31 c0 48 c7 86 88 00 00 00 c0 f0 1b a0 c9 c3 0f 1f 84 00 00 00 00 00 55 48 89 e5 0f 1f 44 00 00 <0f> 0b eb fe 0f 1f 00 55 48 89 e5 41 57 41 56 41 55 41 54 53 48 RIP [<ffffffffa018d3c9>] kvm_spurious_fault+0x9/0x10 [kvm] RSP <ffff880079eebc20> This looks lilke the virt instruction resulted in a fault for some reason. Seems to be like a hardware bug ? I will run my setup with an upstream kernel and check what the behavior is. Same here with L1 6.8 L2 6.8 and host AMD A4-5000 APU with Radeon(TM) HD Graphic How can I be of help?

Are you seeing the same trace as above ? What's the kernel version on the host ? |
