A very minimal vmm built using Linux Kernel Virtual Machine for Linux.
Following project is under-development expect unfinished components.
User needs to download and build kernel images from https://www.kernel.org/.
Usage: wiser [OPTION...] --image path-to-kernel-image
wiser - Extremely tiny type-2 hypervisor for linux. Will boot your
unikernel/linux someday.
-c, --vcpu Number of cpu for your vm
-i, --image=IMAGE linux kernel bzImage
-r, --memory Ram size for your vm
-v, --verbose Produce verbose output
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.
Report bugs to https://github.com/flouthoc/wiser/issues.Path to linux kernel bzImage. The bzImage file is in a specific format. It contains concatenated bootsect.o + setup.o + misc.o + piggy.o.
Allow users to load initramfs. Closed in flouthoc#4- Add basic support for Apple hypervisor
