Hi, I'd tried re-compile the kernel, loading all modules but the only thing I can get is a kernel panic, so I don't know how much to do, and Google isn't help me this time. I look into the menus using the search on menuconfig, but the KVM symbol isn't in Virtualization menu (this is the output the search gives to me). I'll keep thinking about it. But thanks anyway for the reply!

Hello,

I'd tried to run a qemu vm using kvm, but I get the message "failed to initialize KVM: no such file or directory". I upgrade the kernel to 4.8.0-rc3 thinking that was a kernel issue (but I don't think it so, really) but nothing. The CPU virtualization is enabled on bios and in the kernel sources, I don't see anything to enable kvm (I think there are enabled by default from some old kernel version onward). I try run `modprobe kvm`, `modprobe kvm_intel`, but nothing. I'd tried review the logs too but I see nothing too.

I attach the /proc/cpuinfo, lsmod and dmesg outputs.

Do anyone knows whats happens? Do I forget something to enable kvm? I don't have this issues on other Linux OS before.

Thanks PD: sorry for my english. It is not my native language.

I am running 4.7.0 kernel with a working qemu/kvm on Intel chipset. My config has these: # grep -i kvm .config CONFIG_HAVE_KVM=y CONFIG_HAVE_KVM_IRQCHIP=y CONFIG_HAVE_KVM_IRQFD=y CONFIG_HAVE_KVM_IRQ_ROUTING=y CONFIG_HAVE_KVM_EVENTFD=y CONFIG_KVM_APIC_ARCHITECTURE=y CONFIG_KVM_MMIO=y CONFIG_KVM_ASYNC_PF=y CONFIG_HAVE_KVM_MSI=y CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT=y CONFIG_KVM_VFIO=y CONFIG_KVM_GENERIC_DIRTYLOG_READ_PROTECT=y CONFIG_KVM_COMPAT=y CONFIG_HAVE_KVM_IRQ_BYPASS=y CONFIG_KVM=m CONFIG_KVM_INTEL=m # CONFIG_KVM_AMD is not set CONFIG_KVM_DEVICE_ASSIGNMENT=y If you make menuconfig for the kernel, you can use /CONFIG_HAVE_KVM to search for individual options, they are some times hard to find through the menus. I am surpised that modprobe did not make them show up in the lsmod yet did not give any error message. Check dmesg|tail right after the modprobe and see if there are any errors. That is as much as I know. Maybe if this doesn't help some one else on the list knows what to look for. -Daryl

Well, I realize my mistake: I'm using as kernel config file the provided with crux-3.2 (kernel 4.1.13), and this kernel has not the virtualization enabled (and I don't find it through menus and configuration files), so I tune up the kernel by hand and the kvm module finally has loaded with 4.7.2 kernel (lsmod shows kvm=1) I'm late so I'll make test with qemu tomorrow, but I think it's gonna be well. Thanks you all for your replies.

Depends on: VIRTUALIZATION [=y] && HAVE_KVM [=y] && HIGH_RES_TIMERS [=y] && NET [=y] So you'll need to make sure these are selected. When they are, the KVM options should appear in menuconfig

I'll keep thinking about it.

But thanks anyway for the reply!
