init error

[heshriti]

when I initialize, using : vm init
I get this:

/usr/local/sbin/vm: ERROR: unable to load vmm.ko!

I tried many things, including rebooting the machine. No luck.

Can you suggest what I can do to resolve?

thank you very much.

[heshriti]

hi, any thoughts on this? thanks in advance.

[handcode]

what's the output if you try to load the vmm module without vm?

kldload vmm

[heshriti]

$ sudo kldload vmm
kldload: can't load vmm: module already loaded or in kernel

[handcode]

If the module is already loaded, kldstat has to return an error, see: util::load_module

what's the output of:
kldstat -v -m vmm && echo "kldstat returned success" || echo "kldstat returned error"

[heshriti]

The kldstat does not recognize vmm:

$ kldstat -v -m vmm && echo "kldstat returned success" || echo "kldstat returned error"
kldstat: can't find module vmm: No such file or directory
kldstat returned error

[heshriti]

But plain kldstat seems to show that vmm is loaded, as follows

$ kldstat

Id Refs Address Size Name
8 1 ... .... vmm.ko

[heshriti]

sorry, so what's the solution for this?

[handcode]

then I guess the error occurs when initializing the module. try unload/load the module and search for error in dmesg.

kldunload vmm
kldload vmm

if you see a error like this in dmesg, your CPU is not supported

vmx_init: processor does not support VMX operation
module_register_init: MOD_LOAD (vmm, 0xffffffff8205f230, 0) error 6

Jens, as yo suggested, I unloaded and reloaded vmm, and that seems to at least initialize the vm module. I was also able to get the switch to work However, the vm setup just fails. $ sudo vm -f install ubuntu ubuntu-16.04.3-server-amd64.iso Could not create VM ubuntu Error in initializing VM

I recommended that you unload/load the module and look for errors in dmesg or /var/log/messages.

Obviously the module is loaded but not initialized correctly.

That's why I still guess that your CPU is not supported or EPT is not activated in BIOS and therefore it doesn't make any sense to try to start a VM because this can't work without a correctly initialized vmm module

It looks like kldstat -m vmm does not work while kldstat -n vmm does.

[churchers]

This appears to be due to issues loading the vmm module, most likely due to missing hardware support.

Either way this doesn't seem to be an issue with vm-bhyve, and if the module can be loaded, which is obviously required, then both kldstat -n & kldstat -m should work. In fact as per the bug above, the current -n method needs to be used as -m may return true if some parts of vmm.ko are loaded (ppt and ivhd), but not the vmm module we actually need.
