modprobe: FATAL: Module nova not found in directory /lib/modules/5.1.0+

[urb31075]

I am executing a set of commands: 1) git clone https://github.com/NVSL/linux-nova.git 2) cd ./linux-nova 3) make menuconfig CONFIG_LIBNVDIMM=y CONFIG_BLK_DEV_PMEM=y CONFIG_FS_DAX=y CONFIG_NOVA_FS=y 4) sudo make bindeb-pkg 5) sudo dpkg -i linux-headers-5.1.0+_5.1.0+-1_amd64.deb sudo dpkg -i linux-image-5.1.0+_5.1.0+-1_amd64.deb sudo dpkg -i linux-image-5.1.0+-dbg_5.1.0+-1_amd64.deb sudo dpkg -i linux-libc-dev_5.1.0+-1_amd64.deb 6) sudo reboot 7) root@shd2:~# uname -r 5.1.0+ 8) root@shd2:~# modprobe nova modprobe: FATAL: Module nova not found in directory /lib/modules/5.1.0+

What else needs to be done?

Looks like you might have compiled nova directly into the kernel (“y”) rather than as module (“m”).
