Hi,
I'm trying to run gem5 SE mode with X86KvmCPU, but get the following error:
Cmdline: build/X86_MOESI_AMD_Base_KVM/gem5.opt --debug-flags=KvmAll
configs/example/se.py --cpu-type=kvm --mem-type=SimpleMemory -c
tests/test-progs/hello/bin/x86/linux/hello
.
panic: KVM: Unknown error when starting vCPU (hw reason: 0x80000021)
@ tick 121227000
[handleKvmExitUnknown:build/X86_MOESI_AMD_Base_KVM/cpu/kvm/base.cc, line
1089]
Memory Usage: 761456 KBytes
Program aborted at tick 121227000
.
(The whole error messages with debug-flag=KvmAll are attached.)
Gem5 build options:
PROTOCOL = 'MOESI_AMD_Base'
TARGET_ISA = 'x86'
USE_KVM = True
CPU_MODELS = 'AtomicSimpleCPU,MinorCPU,O3CPU,TimingSimpleCPU'
Host CPU:
Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz
Virtualization: VT-x
OS & Kernel:
Red Hat Enterprise Linux Server release 6.5 (Santiago)
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10
22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
I've tried to run Qemu with KVM acceleration and it succeeded, so it seems
that the KVM installation in my system is OK.
Any suggestions?
Thanks,
Zehan
